154-409: [REDACTED]   British Empire [REDACTED]   France 1915 1916 1917 1918 Associated articles During the First World War, the Second Battle of Ypres was fought from 22 April – 25 May 1915 for control of the tactically important high ground to the east and south of the Flemish town of Ypres in western Belgium . The First Battle of Ypres had been fought

308-428: A redox mechanism for providing energy to bacteria under anaerobic conditions in sediments. However, XANES spectroscopy measurements have revealed that the charge densities of both sulfur atoms point out to +5 and −1 oxidation states. This observation is consistent with the disproportionation of thiosulfate into sulfate and sulfide as a redox mechanism freeing up energy from microbial fermentation . Thiosulfate ion

462-515: A valence of 2 while the central sulfur atom has a valence of 6. The oxygen atoms have a valence of 2. The S-S distance is appropriate for a single bond. The S-O distances are slightly shorter than the S-O distances in sulfate. A longtime, the oxidation states of the two sulfur atoms in thiosulfate were considered to be +6 as in sulfate and −2 as in sulfide . This view precluded the disproportionation reaction of thiosulfate into sulfate and sulfide as

616-498: A 75 per cent casualty rate. The British press were confused by the attack: The Germans set fire to a chemical product of sulphur chloride which they had placed in front of their own trenches, causing a thick yellow cloud to be blown towards the trenches of the French and Belgians. The cloud of smoke advanced like a yellow low wall, overcoming all those who breathed in poisonous fumes. The French were unable to see what they were doing or what

770-422: A bombardment of the 83rd Brigade in trenches on the forward slope of the ridge, but the first and second infantry assaults were repelled by the survivors. The third German assault of the morning pushed the defenders back. Although the neighbouring 80th Brigade repulsed the attack, the 84th Brigade was pushed back; this left a 2 mi (3.2 km) gap in the line. The Germans were prevented from advancing further by

924-465: A contest of ideologies between the two nations. It was not only Britain's position on the world stage that was at risk: Napoleon threatened to invade Britain itself, just as his armies had overrun many countries of continental Europe . The Napoleonic Wars were therefore ones in which Britain invested large amounts of capital and resources to win. French ports were blockaded by the Royal Navy , which won

1078-612: A decisive victory over a French Imperial Navy - Spanish Navy fleet at the Battle of Trafalgar in 1805. Overseas colonies were attacked and occupied, including those of the Netherlands, which was annexed by Napoleon in 1810. France was finally defeated by a coalition of European armies in 1815. Britain was again the beneficiary of peace treaties: France ceded the Ionian Islands , Malta (which it had occupied in 1798), Mauritius , St Lucia ,

1232-690: A dependency of the New South Wales colony. From 16 June 1840 New South Wales laws applied in New Zealand. This transitional arrangement ended with the Charter for Erecting the Colony of New Zealand on 16 November 1840. The Charter stated that New Zealand would be established as a separate Crown colony on 3 May 1841 with Hobson as its governor. During the 19th century, Britain and the Russian Empire vied to fill

1386-464: A field test of this idea, the chemist Fritz Haber instead proposed using chlorine gas that was heavier-than-air. The German commander Erich von Falkenhayn agreed to try the new weapon but intended to use it in a diversionary attack by the 4th Army . Falkenhayn wanted to use the gas to cover the transfer of Imperial German Army units to the Eastern Front to assist its ally Austria-Hungary with

1540-508: A fixing salt because it acts three to four times faster. Thiosulfate salts have been used to extract or leach gold and silver from their ores as a less toxic alternative to cyanide ion. The enzyme rhodanase (thiosulfate sulfurtransferase) catalyzes the detoxification of cyanide ion by thiosulfate ion by transforming them into thiocyanate ion and sulfite ion: Sodium thiosulfate has been considered as an empirical treatment for cyanide poisoning, along with hydroxocobalamin . It

1694-606: A form that attempted to be more inclusive by showcasing the empire as a family of newly birthed nations with common roots. The last decades of the 19th century saw concerted political campaigns for Irish home rule . Ireland had been united with Britain into the United Kingdom of Great Britain and Ireland with the Act of Union 1800 after the Irish Rebellion of 1798 , and had suffered a severe famine between 1845 and 1852. Home rule

1848-513: A greenish black and yellow, the tongue protrudes and the eyes assume a glassy stare. It is a fiendish death to die. The First Attack on Bellewaarde was conducted by the 3rd Division of V Corps on 16 June 1915 and the Second Attack on Bellewaarde, a larger operation, was conducted from 25 to 26 September 1915 by the 3rd Division of V Corps and the 14th Division of VI Corps. The Battle of Mont Sorrel (2–13 June 1916) took place south of Ypres with

2002-568: A minor settlement, and other treaty ports including Shanghai . During the late 18th and early 19th centuries, the British Crown began to assume an increasingly large role in the affairs of the company. A series of Acts of Parliament were passed, including the Regulating Act of 1773 , Pitt's India Act of 1784 and the Charter Act of 1813 which regulated the company's affairs and established

2156-534: A new line closer to the village. On 26 April the 4, 6 and 7 Battalions of the Northumberland Brigade, the first Territorial brigade to go into action, attacked and gained a foothold in the village but were forced back, having suffered 1,954 casualties. Despite hundreds of casualties, the 2nd Battalion Royal Dublin Fusiliers participated without respite in the battles at Frezenberg and Bellewaarde. On 24 April

2310-541: A perceived violation of the guaranteed Rights of Englishmen . The American Revolution began with a rejection of Parliamentary authority and moves towards self-government. In response, Britain sent troops to reimpose direct rule, leading to the outbreak of war in 1775. The following year, in 1776, the Second Continental Congress issued the Declaration of Independence proclaiming the colonies' sovereignty from

2464-472: A rapid escalation in the number of slaves transported. British ships carried a third of all slaves shipped across the Atlantic—approximately 3.5 million Africans —until the abolition of the trade by Parliament in 1807 (see § Abolition of slavery ). To facilitate the shipment of slaves, forts were established on the coast of West Africa, such as James Island , Accra and Bunce Island . In

2618-524: A security threat to Great Britain or mark the beginning of the break-up of the empire. A second Home Rule bill was defeated for similar reasons. A third bill was passed by Parliament in 1914, but not implemented because of the outbreak of the First World War leading to the 1916 Easter Rising . By the turn of the 20th century, fears had begun to grow in Britain that it would no longer be able to defend

2772-812: A series of Anglo-Mysore wars in Southern India with the Sultanate of Mysore under Hyder Ali and then Tipu Sultan . Defeats in the First Anglo-Mysore war and stalemate in the Second were followed by victories in the Third and the Fourth . Following Tipu Sultan's death in the fourth war in the Siege of Seringapatam (1799) , the kingdom became a protectorate of the company. The East India Company fought three Anglo-Maratha Wars with

2926-498: A smoke screen, alerted the troops. When the gas reached the front Allied trenches, soldiers began to complain of chest pains and a burning sensation in the throat. Captain Francis Scrimger of the 2nd Canadian Field Ambulance may have passed the order to use urine to counteract the gas, on the advice of Lieutenant-Colonel George Gallie Nasmith. Soldiers realised they were being gassed and many ran as fast as they could. An hour after

3080-686: A target presented itself, until dusk. By the end of the battle, British forces had withdrawn to a new line 3 miles closer to Ypres, thereby resulting in a compression of its surrounding salient. The city, bombarded by artillery fire, was demolished. Although poison gas had been used on the Eastern Front, it surprised the Allies and about 7,000 gas casualties were transported in field ambulances and treated in casualty clearing stations. In May and June, 350 British deaths were recorded from gas poisoning. Both sides developed gas weapons and counter-measures, which changed

3234-655: A way station for its ships travelling to and from its colonies in the East Indies . Britain formally acquired the colony, and its large Afrikaner (or Boer ) population in 1806, having occupied it in 1795 to prevent its falling into French hands during the Flanders Campaign . British immigration to the Cape Colony began to rise after 1820, and pushed thousands of Boers , resentful of British rule, northwards to found their own—mostly short-lived— independent republics , during

3388-446: Is a component of the very rare mineral sidpietersite Pb 4 (S 2 O 3 )O 2 (OH) 2 . The presence of this anion in the mineral bazhenovite was disputed. Thiosulfate is an acceptable common name and used almost always. The functional replacement IUPAC name is sulfurothioate ; the systematic additive IUPAC name is trioxidosulfidosulfate(2−) or trioxido-1 κ O -disulfate( S — S )(2−) . Thiosulfate also refers to

3542-765: Is most effective in a pre-hospital setting, since immediate administration by emergency personnel is necessary to reverse rapid intracellular hypoxia caused by the inhibition of cellular respiration , at complex IV . It activates thiosulfate sulfurtransferase ( TST ) in mitochondria. TST is associated with protection against obesity and type II (insulin resistant) diabetes . Thiosulfate can also work as electron donor for growth of bacteria oxidizing sulfur , such as Chlorobium limicola forma thiosulfatophilum . These bacteria use electrons from thiosulfate (and other sources) and carbon from carbon dioxide to synthesize carbon compounds through reverse Krebs cycle . Some bacteria can metabolise thiosulfates. Thiosulfate ion

3696-434: Is produced by the reaction of sulfite ion with elemental sulfur, and by incomplete oxidation of sulfides (e.g. pyrite oxidation). Sodium thiosulfate can be formed by disproportionation of sulfur dissolving in sodium hydroxide (similar to phosphorus ). Thiosulfate ions reacts with acids to give sulfur dioxide and various sulfur rings: This reaction may be used to generate sulfur colloids and demonstrate

3850-641: Is related to its role in of silver-based photography . Also reflecting its affinity for metals , thiosulfate ion rapidly corrodes metals in acidic conditions. Steel and stainless steel are particularly sensitive to pitting corrosion induced by thiosulfate ions. Molybdenum improves the resistance of stainless steel toward pitting (AISI 316L hMo). In alkaline aqueous conditions and medium temperature (60 °C), carbon steel and stainless steel (AISI 304L, 316L) are not attacked, even at high concentration of base (30%w  KOH ), thiosulfate ion (10%w) and in presence of fluoride ion (5%w  KF ). In

4004-551: Is seen by some historians as the event defining the transition between the first and second empires, in which Britain shifted its attention away from the Americas to Asia, the Pacific and later Africa. Adam Smith 's Wealth of Nations , published in 1776, had argued that colonies were redundant, and that free trade should replace the old mercantilist policies that had characterised the first period of colonial expansion, dating back to

4158-415: The 16th Battalion (Canadian Scottish) of the 3rd Brigade arriving to support the advance. Both battalions attacked with over 800 men, in waves of two companies each, at 11:46 p.m. Without reconnaissance , the battalions ran into obstacles halfway to their objective. Engaged by small-arms fire from the wood, they began an impromptu bayonet charge. The attack cleared the former oak plantation of Germans at

4312-698: The Acts of Union 1707 . The 18th century saw the newly united Great Britain rise to be the world's dominant colonial power, with France becoming its main rival on the imperial stage. Great Britain, Portugal, the Netherlands, and the Holy Roman Empire continued the War of the Spanish Succession, which lasted until 1714 and was concluded by the Treaty of Utrecht . Philip V of Spain renounced his and his descendants' claim to

4466-563: The Age of Discovery in the 15th and 16th centuries, Portugal and Spain pioneered European exploration of the globe, and in the process established large overseas empires. Envious of the great wealth these empires generated, England, France , and the Netherlands began to establish colonies and trade networks of their own in the Americas and Asia . A series of wars in the 17th and 18th centuries with

4620-656: The American War of Independence towards the end of the 18th century, has been referred to by some historians as the "First British Empire". England's early efforts at colonisation in the Americas met with mixed success. An attempt to establish a colony in Guiana in 1604 lasted only two years and failed in its main objective to find gold deposits. Colonies on the Caribbean islands of St Lucia  (1605) and Grenada  (1609) rapidly folded. The first permanent English settlement in

4774-546: The Battle of Vimy Ridge in a similar light. The important contribution of the Dominions to the war effort was recognised in 1917 by British prime minister David Lloyd George when he invited each of the Dominion prime ministers to join an Imperial War Cabinet to co-ordinate imperial policy. Thiosulfate Thiosulfate is tetrahedral at the central S atom. Thiosulfate ion has C 3v symmetry. The external sulfur atom has

4928-681: The British economy . Added to this was the cost of suppressing regular slave rebellions . With support from the British abolitionist movement, Parliament enacted the Slave Trade Act in 1807, which abolished the slave trade in the empire. In 1808, Sierra Leone Colony was designated an official British colony for freed slaves. Parliamentary reform in 1832 saw the influence of the West India Committee decline. The Slavery Abolition Act , passed

5082-823: The Caribbean in the British West Indies , British colonial expansion turned towards Asia, Africa , and the Pacific . After the defeat of France in the Napoleonic Wars (1803–1815), Britain emerged as the principal naval and imperial power of the 19th century and expanded its imperial holdings. It pursued trade concessions in China and Japan, and territory in Southeast Asia . The " Great Game " and " Scramble for Africa " also ensued. The period of relative peace (1815–1914) during which

5236-764: The First Anglo-Afghan War was a disaster for Britain. When Russia invaded the Ottoman Balkans in 1853, fears of Russian dominance in the Mediterranean and the Middle East led Britain and France to enter the war in support of the Ottoman Empire and invade the Crimean Peninsula to destroy Russian naval capabilities. The ensuing Crimean War (1854–1856), which involved new techniques of modern warfare ,

5390-538: The Gorlice–Tarnów offensive against the Russian Empire . The gas would be released by siphoning liquid chlorine out of cylinders; the gas could not be released directly because the valves would freeze; wind would carry the gas to the enemy lines. 5,730 gas cylinders, the largest weighing 40 kg (88 lb), were carried into the front line. Installation was supervised by Haber, Otto Hahn , James Franck and Gustav Hertz . Twice cylinders were breached by shell fire,

5544-658: The Government of India Act 1858 , establishing the British Raj , where an appointed governor-general administered India and Queen Victoria was crowned the Empress of India . India became the empire's most valuable possession, "the Jewel in the Crown", and was the most important source of Britain's strength. A series of serious crop failures in the late 19th century led to widespread famines on

5698-832: The Great Trek of the late 1830s and early 1840s. In the process the Voortrekkers clashed repeatedly with the British, who had their own agenda with regard to colonial expansion in South Africa and to the various native African polities, including those of the Sotho people and the Zulu Kingdom . Eventually, the Boers established two republics that had a longer lifespan: the South African Republic or Transvaal Republic (1852–1877; 1881–1902) and

The French were still majority shareholders and attempted to weaken the British position, but a compromise was reached with the 1888 Convention of Constantinople , which made the Canal officially neutral territory. With competitive French, Belgian and Portuguese activity in

6006-576: The Mahdist Army in 1896 and rebuffed an attempted French invasion at Fashoda in 1898. Sudan was nominally made an Anglo-Egyptian condominium , but a British colony in reality. British gains in Southern and East Africa prompted Cecil Rhodes , pioneer of British expansion in Southern Africa , to urge a " Cape to Cairo " railway linking the strategically important Suez Canal to the mineral-rich south of

6160-618: The Maratha Confederacy . The First Anglo-Maratha War ended in 1782 with a restoration of the pre-war status quo . The Second and Third Anglo-Maratha wars resulted in British victories. After the surrender of Peshwa Bajirao II on 1818, the East India Company acquired control of a large majority of the Indian subcontinent. Britain was challenged again by France under Napoleon, in a struggle that, unlike previous wars, represented

6314-650: The Middle East . Increasing degrees of autonomy were granted to its white settler colonies , some of which were formally reclassified as Dominions by the 1920s. By the start of the 20th century, Germany and the United States had begun to challenge Britain's economic lead. Military, economic and colonial tensions between Britain and Germany were major causes of the First World War , during which Britain relied heavily on its empire. The conflict placed enormous strain on its military, financial, and manpower resources. Although

6468-690: The Orange Free State (1854–1902). In 1902 Britain occupied both republics, concluding a treaty with the two Boer Republics following the Second Boer War (1899–1902). In 1869 the Suez Canal opened under Napoleon III , linking the Mediterranean Sea with the Indian Ocean . Initially the Canal was opposed by the British; but once opened, its strategic value was quickly recognised and became

6622-532: The Rayleigh scattering of light in physics . If white light is shone from below, blue light is seen from sideways and orange light from above, due to the same mechanisms that color the sky at midday and dusk . Thiosulfate ions react with iodine to give tetrathionate ions: This reaction is key for iodometry . With bromine (X = Br) and chlorine (X = Cl), thiosulfate ions are oxidized to sulfate ions: Thiosulfate ion extensively forms diverse complexes with transition metals . This reactivity

6776-407: The Ross rifle worsened tactical difficulties. The Canadian Division received several thousand replacements shortly after the battle. At Second Ypres, the smallest tactical unit in the infantry was a company ; by 1917 it would be the section . The Canadians were employed offensively later in 1915 but not successfully. The battle was the beginning of a long period of analysis and experiment to improve

6930-411: The Royal African Company was granted a monopoly on the supply of slaves to the British colonies in the Caribbean. The company would transport more slaves across the Atlantic than any other, and significantly grew England's share of the trade, from 33 per cent in 1673 to 74 per cent in 1683. The removal of this monopoly between 1688 and 1712 allowed independent British slave traders to thrive, leading to

7084-500: The Saint John and Saint Croix river valleys, then part of Nova Scotia , felt too far removed from the provincial government in Halifax , so London split off New Brunswick as a separate colony in 1784. The Constitutional Act of 1791 created the provinces of Upper Canada (mainly English speaking ) and Lower Canada (mainly French-speaking ) to defuse tensions between the French and British communities, and implemented governmental systems similar to those employed in Britain, with

7238-443: The Seychelles , and Tobago ; Spain ceded Trinidad ; the Netherlands ceded Guiana , Ceylon and the Cape Colony , while the Danish ceded Heligoland . Britain returned Guadeloupe , Martinique , French Guiana , and Réunion to France; Menorca to Spain; Danish West Indies to Denmark and Java and Suriname to the Netherlands. With the advent of the Industrial Revolution , goods produced by slavery became less important to

7392-441: The Treaty of Paris of 1763 had important consequences for the future of the British Empire. In North America, France's future as a colonial power effectively ended with the recognition of British claims to Rupert's Land, and the ceding of New France to Britain (leaving a sizeable French-speaking population under British control) and Louisiana to Spain. Spain ceded Florida to Britain. Along with its victory over France in India,

7546-408: The United Kingdom and its predecessor states. It began with the overseas possessions and trading posts established by England in the late 16th and early 17th centuries. At its height in the 19th and early 20th centuries, it was the largest empire in history and, for a century, was the foremost global power. By 1913, the British Empire held sway over 412 million people, 23 percent of

7700-417: The Victorian gold rush , making its capital Melbourne for a time the richest city in the world. The British also expanded their mercantile interests in the North Pacific. Spain and Britain had become rivals in the area, culminating in the Nootka Crisis in 1789. Both sides mobilised for war, but when France refused to support Spain it was forced to back down, leading to the Nootka Convention . The outcome

7854-454: The War of 1812 , and invaded Canadian territory. In response, Britain invaded the US, but the pre-war boundaries were reaffirmed by the 1814 Treaty of Ghent , ensuring Canada's future would be separate from that of the United States. Since 1718, transportation to the American colonies had been a penalty for various offences in Britain, with approximately one thousand convicts transported per year. Forced to find an alternative location after

8008-545: The metropole and the entirety of the empire while at the same time maintaining the policy of "splendid isolation". Germany was rapidly rising as a military and industrial power and was now seen as the most likely opponent in any future war. Recognising that it was overstretched in the Pacific and threatened at home by the Imperial German Navy , Britain formed an alliance with Japan in 1902 and with its old enemies France and Russia in 1904 and 1907, respectively. Britain's fears of war with Germany were realised in 1914 with

8162-413: The privateers John Hawkins and Francis Drake to engage in slave-raiding attacks against Spanish and Portuguese ships off the coast of West Africa with the aim of establishing an Atlantic slave trade . This effort was rebuffed and later, as the Anglo-Spanish Wars intensified, Elizabeth I gave her blessing to further privateering raids against Spanish ports in the Americas and shipping that

8316-440: The protectionism of Spain and Portugal. The growth of trade between the newly independent United States and Britain after 1783 seemed to confirm Smith's view that political control was not necessary for economic success. The war to the south influenced British policy in Canada, where between 40,000 and 100,000 defeated Loyalists had migrated from the new United States following independence. The 14,000 Loyalists who went to

8470-399: The spice trade of the East Indies archipelago to the Netherlands and the textiles industry of India to England, but textiles soon overtook spices in terms of profitability. Peace between England and the Netherlands in 1688 meant the two countries entered the Nine Years' War as allies, but the conflict—waged in Europe and overseas between France, Spain and the Anglo-Dutch alliance—left

8624-475: The "Sugar Revolution" transformed the Caribbean economy in the mid-17th century. Large sugarcane plantations were first established in the 1640s on Barbados, with assistance from Dutch merchants and Sephardic Jews fleeing Portuguese Brazil . At first, sugar was grown primarily using white indentured labour , but rising costs soon led English traders to embrace the use of imported African slaves. The enormous wealth generated by slave-produced sugar made Barbados

8778-480: The "jugular vein of the Empire". In 1875, the Conservative government of Benjamin Disraeli bought the indebted Egyptian ruler Isma'il Pasha 's 44 per cent shareholding in the Suez Canal for £4 million (equivalent to £480 million in 2023). Although this did not grant outright control of the strategic waterway, it did give Britain leverage. Joint Anglo-French financial control over Egypt ended in outright British occupation in 1882. Although Britain controlled

8932-428: The 1730s. This trade, illegal since it was outlawed by China in 1729, helped reverse the trade imbalances resulting from the British imports of tea, which saw large outflows of silver from Britain to China. In 1839, the confiscation by the Chinese authorities at Canton of 20,000 chests of opium led Britain to attack China in the First Opium War , and resulted in the seizure by Britain of Hong Kong Island , at that time

The Third Battle of Ypres, also known as the Battle of Passchendaele , was fought from 31 July to 10 November 1917. Canadian participation in the Battle of Gravenstafel is commemorated on the Saint Julien Memorial in the village. During the Second Battle of Ypres, Lieutenant colonel John McCrae , Medical Officer of

9394-400: The 2nd Royal Dublin Fusiliers, shows that their C.O. Lieutenant Colonel Arthur Loveband suspected a gas attack and had warned all company officers. Later the Germans threw up red lights over their trench, which would signal a gas release. We had only just time to get our respirators on before the gas was over us. German forces managed to advance and occupy the British line to north and left of

No further attempts to establish English colonies in the Americas were made until well into the reign of Queen Elizabeth I , during the last decades of the 16th century. In the meantime, Henry VIII 's 1533 Statute in Restraint of Appeals had declared "that this realm of England is an Empire". The Protestant Reformation turned England and Catholic Spain into implacable enemies. In 1562, Elizabeth I encouraged

The transatlantic slave trade played a pervasive role in British economic life, and became a major economic mainstay for western port cities. Ships registered in Bristol , Liverpool and London were responsible for

10164-443: The British Empire as the new United States of America . The entry of French and Spanish forces into the war tipped the military balance in the Americans' favour and after a decisive defeat at Yorktown in 1781, Britain began negotiating peace terms. American independence was acknowledged at the Peace of Paris in 1783. The loss of such a large portion of British America , at the time Britain's most populous overseas possession,

Alongside the formal control that Britain exerted over its colonies, its dominance of much of world trade, and of its oceans, meant that it effectively controlled the economies of, and readily enforced its interests in, many regions , such as Asia and Latin America . It also came to dominate

10472-425: The British defeated the Nawab of Bengal and his French allies, left the British East India Company in control of Bengal and as a major military and political power in India. France was left control of its enclaves but with military restrictions and an obligation to support British client states , ending French hopes of controlling India. In the following decades the British East India Company gradually increased

10626-447: The British were advised by John Scott Haldane to counter the effects of the gas by urinating into a cloth and breathing through it. Both sides set about developing more effective gas masks . The village of St. Julien (now Sint-Juliaan ; 50°53′24″N 2°56′13″E  /  50.890°N 2.937°E  / 50.890; 2.937 ) was in the rear of the 1st Canadian Division until the poison-gas attack of 22 April, when it became

The death of Charles II of Spain in 1700 and his bequeathal of Spain and its colonial empire to Philip V of Spain , a grandson of the King of France , raised the prospect of the unification of France, Spain and their respective colonies, an unacceptable state of affairs for England and

10934-436: The French 45th and 87th divisions. The French troops in the path of the gas cloud suffered 2,000–3,000 casualties, with 800 to 1,400 fatalities. Troops fled in all directions, ...haggard, their overcoats thrown off or opened wide, their scarves pulled off, running like madmen, directionless, shouting for water, spitting blood, some even rolling on the ground making desperate efforts to breathe.

11088-515: The French Division would have stood firm. The Canadian Division mounted an effective defence but had 5,975 casualties by its withdrawal on 3 May. The division was unprepared for the warfare prevailing on the Western Front, where linear tactics were ineffective against attackers armed with magazine rifles and machine guns. The Canadian field artillery had been effective but the deficiencies of

11242-507: The French front was left undefended. German infantry followed well behind the cloud, breathing through cotton pads soaked with sodium thiosulfate solution, and occupied the villages of Langemark and Pilkem, where they dug in, even though they might have occupied Ypres almost unopposed. They had taken 2,000 prisoners and 51 guns. Canadian troops defending the southern flank of the break-in identified chlorine because it smelled like their drinking water. The Germans released more chlorine gas at them

11396-673: The French throne, and Spain lost its empire in Europe. The British Empire was territorially enlarged: from France, Britain gained Newfoundland and Acadia , and from Spain, Gibraltar and Menorca . Gibraltar became a critical naval base and allowed Britain to control the Atlantic entry and exit point to the Mediterranean . Spain ceded the rights to the lucrative asiento (permission to sell African slaves in Spanish America ) to Britain. With

11550-586: The Germans released another gas cloud towards the re-formed Canadian line just west of St. Julien. Word was passed to the troops to urinate on their handkerchiefs and place them over their nose and mouth. The countermeasures were insufficient, and German troops took the village. The next day the York and Durham brigades of the Northumberland Division counter-attacked, failing to secure their objectives but establishing

11704-487: The Hell gas was. When we got to Ypres we found a lot of Canadians lying there dead from gas the day before, poor devils, and it was quite a horrible sight for us young men. I was only twenty so it was quite traumatic and I've never forgotten nor ever will forget it. The French soldiers were naturally taken by surprise. Some got away in time, but many, alas! not understanding the new danger, were not so fortunate, and were overcome by

11858-549: The Māori population. The UK government finally decided to act, dispatching Captain William Hobson with instructions to take formal possession after obtaining native consent. There was no central Māori authority able to represent all New Zealand so, on 6 February 1840, Hobson and many Māori chiefs signed the Treaty of Waitangi in the Bay of Islands; most other chiefs signing in stages over

12012-697: The Netherlands and France left Britain the dominant colonial power in North America . Britain became a major power in the Indian subcontinent after the East India Company 's conquest of Mughal Bengal at the Battle of Plassey in 1757. The American War of Independence resulted in Britain losing some of its oldest and most populous colonies in North America by 1783. While retaining control of British North America (now Canada ) and territories in and near

12166-684: The Netherlands as a colonial power, in the short term the Netherlands' more advanced financial system and the three Anglo-Dutch Wars of the 17th century left it with a stronger position in Asia. Hostilities ceased after the Glorious Revolution of 1688 when the Dutch William of Orange ascended the English throne, bringing peace between the Dutch Republic and England. A deal between the two nations left

12320-468: The Pacific between 1769 and 1777, James Cook visited New Zealand . He was followed by an assortment of Europeans and Americans which including whalers, sealers, escaped convicts from New South Wales, missionaries and adventurers. Initially, contact with the indigenous Māori people was limited to the trading of goods, although interaction increased during the early decades of the 19th century with many trading and missionary stations being set up, especially in

12474-650: The Pacific for the extension of the North American fur trade . Alexander Mackenzie of the North West Company led the first, starting out in 1792, and a year later he became the first European to reach the Pacific overland north of the Rio Grande , reaching the ocean near present-day Bella Coola . This preceded the Lewis and Clark Expedition by twelve years. Shortly thereafter, Mackenzie's companion, John Finlay , founded

12628-602: The Royal Navy during the Seven Years' War, and the two continued to co-operate in arenas outside India: the eviction of the French from Egypt (1799), the capture of Java from the Netherlands (1811), the acquisition of Penang Island (1786), Singapore (1819) and Malacca (1824), and the defeat of Burma (1826). From its base in India, the company had been engaged in an increasingly profitable opium export trade to Qing China since

12782-518: The Royal Scots arrived in Ypres just after the chlorine-gas attack on 22 April 1915: We knew there was something was wrong. We started to march towards Ypres but we couldn't get past on the road with refugees coming down the road. We went along the railway line to Ypres and there were people, civilians and soldiers, lying along the roadside in a terrible state. We heard them say it was gas. We didn't know what

12936-557: The Seven Years' War therefore left Britain as the world's most powerful maritime power . During the 1760s and early 1770s, relations between the Thirteen Colonies and Britain became increasingly strained, primarily because of resentment of the British Parliament's attempts to govern and tax American colonists without their consent. This was summarised at the time by the colonists' slogan " No taxation without representation ",

13090-740: The Spanish, and in 1666 succeeded in colonising the Bahamas . In 1670, Charles II incorporated by royal charter the Hudson's Bay Company (HBC), granting it a monopoly on the fur trade in the area known as Rupert's Land , which would later form a large proportion of the Dominion of Canada . Forts and trading posts established by the HBC were frequently the subject of attacks by the French, who had established their own fur trading colony in adjacent New France . Two years later,

13244-690: The annexation of the Dutch colony of New Netherland in 1664, following the capture of New Amsterdam , which was renamed New York . Although less financially successful than colonies in the Caribbean, these territories had large areas of good agricultural land and attracted far greater numbers of English emigrants, who preferred their temperate climates. The British West Indies initially provided England's most important and lucrative colonies. Settlements were successfully established in St. Kitts  (1624), Barbados  (1627) and Nevis  (1628), but struggled until

13398-555: The apprenticeship system was abolished in 1838. The British government compensated slave-owners. Between 1815 and 1914, a period referred to as Britain's "imperial century" by some historians, around 10 million sq mi (26 million km ) of territory and roughly 400 million people were added to the British Empire. Victory over Napoleon left Britain without any serious international rival, other than Russia in Central Asia . Unchallenged at sea, Britain adopted

13552-602: The area on which the gas had spread itself some minutes before, and took possession of the arms of the dead men. They made no prisoners. Whenever they saw a soldier whom the fumes had not quite killed they snatched away his rifle and advised him to lie down "to die better." The Germans moved field artillery forward, placing three army corps opposite the 27th and 28th Divisions on the Frezenberg ridge ( 50°52′05″N 2°57′00″E  /  50.868°N 2.950°E  / 50.868; 2.950 ). The German attack began on 8 May with

13706-523: The armies of the Dominions , as well as many thousands of volunteers from the Crown colonies. The contributions of Australian and New Zealand troops during the 1915 Gallipoli Campaign against the Ottoman Empire had a great impact on the national consciousness at home and marked a watershed in the transition of Australia and New Zealand from colonies to nations in their own right. The countries continue to commemorate this occasion on Anzac Day . Canadians viewed

13860-456: The attack began, there was a 1,500-yard (1.4 km) gap in the Allied line. Fearing the chlorine, few German soldiers moved forward and the delay enabled Canadian and British troops to retake the position before the Germans could exploit the gap. After the first German chlorine-gas attacks, Allied troops were supplied with masks of cotton pads soaked in urine; it had been discovered that the urea in

14014-553: The battalion, subjected to a German gas attack near St. Julien, was nearly annihilated. The German Army first used chlorine-gas cylinders in April 1915 against the French Army at Ypres, when yellow-green clouds drifted towards the Allied trenches. The gas had a distinctive odour, resembling pineapple and pepper. The French officers, assuming at first that the German infantry were advancing behind

14168-568: The bulk of British slave trading. For the transported, harsh and unhygienic conditions on the slaving ships and poor diets meant that the average mortality rate during the Middle Passage was one in seven. At the end of the 16th century, England and the Dutch Empire began to challenge the Portuguese Empire 's monopoly of trade with Asia, forming private joint-stock companies to finance

14322-516: The business of establishing its own overseas colonies. The British Empire began to take shape during the early 17th century, with the English settlement of North America and the smaller islands of the Caribbean, and the establishment of joint-stock companies , most notably the East India Company , to administer colonies and overseas trade. This period, until the loss of the Thirteen Colonies after

14476-581: The coasts of Africa and Brazil to China , and France had begun to settle the Saint Lawrence River area, later to become New France . Although England tended to trail behind Portugal, Spain, and France in establishing overseas colonies, it carried out its first modern colonisation, referred to as the Munster Plantations , in 16th century Ireland by settling it with English and Welsh Protestant settlers. England had already colonised part of

14630-465: The colony was abandoned two years later. The Darien scheme was a financial disaster for Scotland: a quarter of Scottish capital was lost in the enterprise. The episode had major political consequences, helping to persuade the government of the Kingdom of Scotland of the merits of turning the personal union with England into a political and economic one under the Kingdom of Great Britain established by

14784-457: The continent. During the 1880s and 1890s, Rhodes, with his privately owned British South Africa Company , occupied and annexed territories named after him, Rhodesia . The path to independence for the white colonies of the British Empire began with the 1839 Durham Report , which proposed unification and self-government for Upper and Lower Canada, as a solution to political unrest which had erupted in armed rebellions in 1837. This began with

14938-533: The counter-attacks of the Princess Patricia's Canadian Light Infantry (PPCLI) and a night move by the 10th Brigade. The PPCLI had a costly success; their 700 men were reduced to 150, who were in no shape to fight. On 24 May the Germans released a gas attack that hit Shell Trap Farm and to the area around the north west, which was affected the most by the attack. A report of the event by Captain Thomas Leahy, of

15092-555: The country following the Norman invasion of Ireland in 1169. Several people who helped establish the Munster plantations later played a part in the early colonisation of North America, particularly a group known as the West Country Men . In 1578, Elizabeth I granted a patent to Humphrey Gilbert for discovery and overseas exploration. That year, Gilbert sailed for the Caribbean with

15246-477: The decline of the empire. India , Britain's most valuable and populous possession, achieved independence in 1947 as part of a larger decolonisation movement, in which Britain granted independence to most territories of the empire. The Suez Crisis of 1956 confirmed Britain's decline as a global power, and the handover of Hong Kong to China on 1 July 1997 symbolised for many the end of the British Empire, though fourteen overseas territories that are remnants of

15400-661: The effectiveness of Canadian infantry weapons, artillery and liaison between infantry and artillery. After the war, German casualties from 21 April to 30 May were recorded as 34,933 by the official historians of the Reichsarchiv . In the British Official History, J. E. Edmonds and G. C. Wynne recorded British losses of 59,275 casualties, the French about 18,000 casualties on 22 April and another 3,973 from 26 to 29 April. Canadian casualties from 22 April to 3 May were 5,975, of whom about 1,000 men were killed. The worst day

15554-408: The effects of chlorine gas, It produces a flooding of the lungs—it is an equivalent death to drowning only on dry land. The effects are these—a splitting headache and terrific thirst (to drink water is instant death), a knife edge of pain in the lungs and the coughing up of a greenish froth off the stomach and the lungs, ending finally in insensibility and death. The colour of the skin from white turns

15708-633: The empire achieved its largest territorial extent immediately after the First World War, Britain was no longer the world's preeminent industrial or military power. In the Second World War , Britain's colonies in East Asia and Southeast Asia were occupied by the Empire of Japan . Despite the final victory of Britain and its allies , the damage to British prestige and the British economy helped accelerate

15862-531: The empire remain under British sovereignty . After independence, many former British colonies, along with most of the dominions, joined the Commonwealth of Nations , a free association of independent states. Fifteen of these, including the United Kingdom, retain the same person as monarch , currently King Charles III . The foundations of the British Empire were laid when England and Scotland were separate kingdoms. In 1496, King Henry VII of England , following

16016-415: The era of silver-based photography , thiosulfate salts were consumed on a large scale as a "fixer" reagent. This application exploits thiosulfate ion's ability to dissolve silver halides . Sodium thiosulfate , commonly called hypo (from "hyposulfite"), was widely used in photography to fix black and white negatives and prints after the developing stage; modern "rapid" fixers use ammonium thiosulfate as

16170-431: The examples our gallant Allies have shown of dogged and tenacious courage in the many trying situations in which they have been placed throughout the course of this campaign it is quite superfluous for me to dwell on this aspect of the incident, and I would only express my firm conviction that, if any troops in the world had been able to hold their trenches in the face of such a treacherous and altogether unexpected onslaught,

16324-570: The exception of international relations . Australia and New Zealand achieved similar levels of self-government after 1900, with the Australian colonies federating in 1901 . The term "dominion status" was officially introduced at the 1907 Imperial Conference . As the dominions gained greater autonomy, they would come to be recognized as distinct realms of the empire with unique customs and symbols of their own. Imperial identity, through imagery such as patriotic artworks and banners, began developing into

16478-456: The eyes, but the sight is not damaged. Dusk was falling when from the German trenches in front of the French line rose that strange green cloud of death. The light north-easterly breeze wafted it toward them, and in a moment death had them by the throat. One cannot blame them that they broke and fled. In the gathering dark of that awful night they fought with the terror, running blindly in the gas-cloud, and dropping with breasts heaving in agony and

16632-658: The first permanent European settlement in British Columbia , Fort St. John . The North West Company sought further exploration and backed expeditions by David Thompson , starting in 1797, and later by Simon Fraser . These pushed into the wilderness territories of the Rocky Mountains and Interior Plateau to the Strait of Georgia on the Pacific Coast, expanding British North America westward. The East India Company fought

16786-595: The following day. Casualties were especially heavy for the 13th Battalion (Royal Highlanders of Canada) of the Canadian Expeditionary Force (CEF), which was enveloped on three sides and had over-extended its left flank after the Algerian Division broke. In an action at Kitcheners' Wood , the 10th Battalion of the 2nd Canadian Brigade was ordered to counter-attack in the gap created by the gas attack. They formed up after 11:00 p.m. on 22 April, with

16940-562: The following months. William Hobson declared British sovereignty over all New Zealand on 21 May 1840, over the North Island by cession and over the South Islnd by discovery (the island was sparsely populated and deemed terra nullius ). Hobson became Lieutenant-Governor, subject to Governor Sir George Gipps in Sydney, with British possession of New Zealand initially administered from Australia as

17094-510: The following year, abolished slavery in the British Empire on 1 August 1834, finally bringing the empire into line with the law in the UK (with the exception of the territories administered by the East India Company and Ceylon, where slavery was ended in 1844). Under the Act, slaves were granted full emancipation after a period of four to six years of "apprenticeship". Facing further opposition from abolitionists,

17248-584: The formations involved. In The Battles of Ypres, 1915 six engagements involving the Second Army were recorded, four during the Second Battle (22 April – 25 May). On 22 April 1915 at about 5:00 p.m. , the 4th Army released 171 t (168 long tons) of chlorine gas on a 6.5-kilometre (4.0 mi) front between the hamlets of Langemark and Gravenstafel on the Allied line held by French Territorial and Troupes coloniales (Moroccan and Algerian troops) of

17402-458: The front line. Some of the first fighting in the village involved the stand of lance corporal Frederick Fisher of the 13th Battalion CEF's machine-gun detachment; Fisher went out twice with a handful of men and a Colt machine gun, preventing advancing German troops from passing through St. Julien into the rear of the Canadian front line. He was killed the following day. On the morning of 24 April,

17556-440: The fumes and died poisoned. Among those who escaped nearly all cough and spit blood, the chlorine-attacking the mucous membrane. The dead were turned black at once. About 15 minutes after letting the gas escape the Germans got out of their trenches. Some of them were sent on in advance, with masks over their heads, to ascertain if the air had become breathable. Having discovered that they could advance, they arrived in large numbers in

17710-679: The government on the suitability of Botany Bay for the establishment of a penal settlement , and in 1787 the first shipment of convicts set sail, arriving in 1788. Unusually, Australia was claimed through proclamation. Indigenous Australians were considered too uncivilised to require treaties, and colonisation brought disease and violence that together with the deliberate dispossession of land and culture were devastating to these peoples. Britain continued to transport convicts to New South Wales until 1840, to Tasmania until 1853 and to Western Australia until 1868. The Australian colonies became profitable exporters of wool and gold, mainly because of

17864-490: The increasingly healthy profits of colonial trade remained in English hands, Parliament decreed in 1651 that only English ships would be able to ply their trade in English colonies. This led to hostilities with the United Dutch Provinces —a series of Anglo-Dutch Wars —which would eventually strengthen England's position in the Americas at the expense of the Dutch. In 1655, England annexed the island of Jamaica from

18018-542: The intention of asserting imperial authority and not allowing the sort of popular control of government that was perceived to have led to the American Revolution. Tensions between Britain and the United States escalated again during the Napoleonic Wars , as Britain tried to cut off American trade with France and boarded American ships to impress men into the Royal Navy . The United States Congress declared war,

18172-477: The intention of engaging in piracy and establishing a colony in North America, but the expedition was aborted before it had crossed the Atlantic. In 1583, he embarked on a second attempt. On this occasion, he formally claimed the harbour of the island of Newfoundland, although no settlers were left behind. Gilbert did not survive the return journey to England and was succeeded by his half-brother, Walter Raleigh , who

18326-560: The larger trade, by 1720, in terms of sales, the British company had overtaken the Dutch. During the middle decades of the 18th century, there were several outbreaks of military conflict on the Indian subcontinent , as the English East India Company and its French counterpart , struggled alongside local rulers to fill the vacuum that had been left by the decline of the Mughal Empire . The Battle of Plassey in 1757, in which

18480-505: The loss of the Thirteen Colonies in 1783, the British government looked for an alternative, eventually turning to Australia . On his first of three voyages commissioned by the government, James Cook reached New Zealand in October 1769. He was the first European to circumnavigate and map the country. From the late 18th century, the country was regularly visited by explorers and other sailors, missionaries , traders and adventurers but no attempt

18634-619: The lower Congo River region undermining orderly colonisation of tropical Africa, the Berlin Conference of 1884–85 was held to regulate the competition between the European powers in what was called the " Scramble for Africa " by defining "effective occupation" as the criterion for international recognition of territorial claims. The scramble continued into the 1890s, and caused Britain to reconsider its decision in 1885 to withdraw from Sudan . A joint force of British and Egyptian troops defeated

18788-487: The most successful colony in the Americas, and one of the most densely populated places in the world. This boom led to the spread of sugar cultivation across the Caribbean, financed the development of non-plantation colonies in North America, and accelerated the growth of the Atlantic slave trade , particularly the triangular trade of slaves, sugar and provisions between Africa, the West Indies and Europe. To ensure that

18942-489: The nature of gas warfare; the French and British used gas at the Battle of Loos in late September. Gas protection was somewhat improved with the issue of improvised respirators made from cotton waste pads impregnated with sodium hyposulphite, sodium bicarbonate and glycerin. The respirators made little difference, however, due to lack of training and the use of local contraptions and poorly made items imported from Britain. The "P helmet" (or "Tube Helmet") soaked in sodium phenate

19096-481: The north. The first of several Church of England missionaries arrived in 1814 and as well as their missionary role, they soon become the only form of European authority in a land that was not subject to British jurisdiction: the closest authority being the New South Wales governor in Sydney. The sale of weapons to Māori resulted from 1818 on in the intertribal warfare of the Musket Wars , with devastating consequences for

19250-708: The other powers of Europe. In 1701, England, Portugal and the Netherlands sided with the Holy Roman Empire against Spain and France in the War of the Spanish Succession , which lasted for thirteen years. In 1695, the Parliament of Scotland granted a charter to the Company of Scotland , which established a settlement in 1698 on the Isthmus of Panama . Besieged by neighbouring Spanish colonists of New Granada , and affected by malaria ,

19404-767: The outbreak of the Anglo-Spanish War of Jenkins' Ear in 1739, Spanish privateers attacked British merchant shipping along the Triangle Trade routes. In 1746, the Spanish and British began peace talks, with the King of Spain agreeing to stop all attacks on British shipping; however, in the 1750 Treaty of Madrid Britain lost its slave-trading rights in Latin America . In the East Indies, British and Dutch merchants continued to compete in spices and textiles. With textiles becoming

19558-421: The outbreak of the First World War. Britain quickly invaded and occupied most of Germany's overseas colonies in Africa. In the Pacific, Australia and New Zealand occupied German New Guinea and German Samoa respectively. Plans for a post-war division of the Ottoman Empire, which had joined the war on Germany's side, were secretly drawn up by Britain and France under the 1916 Sykes–Picot Agreement . This agreement

19712-507: The pad neutralised the chlorine. The pads were held over the face until the gas dispersed. Other soldiers preferred to use a handkerchief, sock or flannel body-belt, dampened with a sodium bicarbonate solution and tied across the mouth and nose, until the gas passed. Soldiers found it difficult to fight like this, and attempts were made to develop a better means of protection against gas attacks. By July 1915, soldiers received efficient gas masks and anti-asphyxiation respirators. Private W. Hay of

19866-434: The passing of the Act of Union in 1840, which created the Province of Canada . Responsible government was first granted to Nova Scotia in 1848, and was soon extended to the other British North American colonies. With the passage of the British North America Act, 1867 by the British Parliament , the Province of Canada, New Brunswick and Nova Scotia were formed into Canada, a confederation enjoying full self-government with

20020-448: The power vacuums that had been left by the declining Ottoman Empire , Qajar dynasty and Qing dynasty . This rivalry in Central Asia came to be known as the "Great Game". As far as Britain was concerned, defeats inflicted by Russia on Persia and Turkey demonstrated its imperial ambitions and capabilities and stoked fears in Britain of an overland invasion of India. In 1839, Britain moved to pre-empt this by invading Afghanistan , but

20174-400: The previous autumn. The Second Battle of Ypres was the first mass use by Germany of poison gas on the Western Front . The German chemist Walther Nernst , who in 1914 was as a volunteer driver, proposed to Colonel Max Bauer , the German general staff officer responsible for liaison with scientists, that they could empty the opposing trenches by a surprise attack with tear gas. Observing

20328-405: The region in 1878 and on all outstanding matters in 1907 with the signing of the Anglo-Russian Entente . The destruction of the Imperial Russian Navy by the Imperial Japanese Navy at the Battle of Tsushima during the Russo-Japanese War of 1904–1905 limited its threat to the British. The Dutch East India Company had founded the Dutch Cape Colony on the southern tip of Africa in 1652 as

20482-450: The role of global policeman, a state of affairs later known as the Pax Britannica , and a foreign policy of " splendid isolation ". Alongside the formal control it exerted over its own colonies, Britain's dominant position in world trade meant that it effectively controlled the economies of many countries, such as China, Argentina and Siam , which has been described by some historians as an " Informal Empire ". British imperial strength

20636-404: The second time three men were killed and fifty wounded. Some of the Germans were protected by miners' oxygen breathing apparatus. The Ypres salient was selected for the attack. It followed the canal, bulging eastward around the town. North of the salient, the Belgian army held the line of the Yser and the north end of the salient was held by two French divisions. The eastern part of the salient

20790-423: The size of the territories under its control, either ruling directly or via local rulers under the threat of force from the Presidency Armies , the vast majority of which was composed of Indian sepoys , led by British officers. The British and French struggles in India became but one theatre of the global Seven Years' War (1756–1763) involving France, Britain, and the other major European powers. The signing of

20944-590: The slow poison of suffocation mantling their dark faces. Hundreds of them fell and died; others lay helpless, froth upon their agonized lips and their racked bodies powerfully sick, with tearing nausea at short intervals. They too would die later—a slow and lingering death of agony unspeakable. The whole air was tainted with the acrid smell of chlorine that caught at the back of men's throats and filled their mouths with its metallic taste. The Germans reported that they treated 200 gas casualties, 12 of whom died. The Allies reported 5,000 killed and 15,000 wounded. Within days

21098-450: The sovereignty of the Crown over the territories that it had acquired. The company's eventual end was precipitated by the Indian Rebellion in 1857, a conflict that had begun with the mutiny of sepoys, Indian troops under British officers and discipline. The rebellion took six months to suppress, with heavy loss of life on both sides. The following year the British government dissolved the company and assumed direct control over India through

21252-419: The subcontinent in which it is estimated that over 15 million people died. The East India Company had failed to implement any coordinated policy to deal with the famines during its period of rule. Later, under direct British rule, commissions were set up after each famine to investigate the causes and implement new policies, which took until the early 1900s to have an effect. On each of his three voyages to

21406-418: The successes of Spain and Portugal in overseas exploration, commissioned John Cabot to lead an expedition to discover a northwest passage to Asia via the North Atlantic. Cabot sailed in 1497, five years after the first voyage of Christopher Columbus , and made landfall on the coast of Newfoundland . He believed he had reached Asia, and there was no attempt to found a colony. Cabot led another voyage to

21560-440: The voyages—the English, later British, East India Company and the Dutch East India Company , chartered in 1600 and 1602 respectively. The primary aim of these companies was to tap into the lucrative spice trade , an effort focused mainly on two regions: the East Indies archipelago , and an important hub in the trade network, India. There, they competed for trade supremacy with Portugal and with each other. Although England eclipsed

21714-434: The world population at the time, and by 1920, it covered 35.5 million km (13.7 million sq mi), 24 per cent of the Earth's total land area. As a result, its constitutional , legal , linguistic , and cultural legacy is widespread. At the peak of its power, it was described as " the empire on which the sun never sets ", as the sun was always shining on at least one of its territories. During

21868-948: Was 24 April, when 3,058 casualties were suffered during infantry attacks, artillery bombardments and gas discharges. In 2003, Clayton wrote that thousands of men of the 45th and 87th divisions ran from the gas but that the number of casualties was low. The Germans overran both divisions' artillery but the survivors rallied and held a new line further back. In 2010, Humphries and Maker, in their translated edition of Der Weltkrieg recorded that by 9 May, there had been more than 35,000 German casualties, 59,275 British between 22 April and 31 May and very many French casualties, 18,000 on 22 April alone. In 2012, Sheldon gave similar figures and in 2014, Greenhalgh wrote that French casualties had been exaggerated by propaganda against German "frightfulness" and that in 1998, Olivier Lepick had estimated that 800–1,400 men were killed by gas in April out of 2,000–3,000 French casualties. Lance Sergeant Elmer Cotton described

22022-405: Was a humiliation for Spain, which practically renounced all sovereignty on the North Pacific coast. This opened the way to British expansion in the area, and a number of expeditions took place; firstly a naval expedition led by George Vancouver which explored the inlets around the Pacific North West, particularly around Vancouver Island . On land, expeditions sought to discover a river route to

22176-429: Was defended by the Canadian Division and two British divisions. The II Corps and V Corps of the Second Army comprised the 1st , 2nd and 3rd Cavalry Divisions and the 4th , 27th , 28th , Northumbrian , Lahore and 1st Canadian divisions. In A record of the Engagements.... (1923) E. A. James used The Official Names of the Battles and Other Engagements.... (1921) to provide a summary of each engagement and

22330-481: Was founded as a haven by Puritan religious separatists, later known as the Pilgrims . Fleeing from religious persecution would become the motive for many English would-be colonists to risk the arduous trans-Atlantic voyage : Maryland was established by English Roman Catholics  (1634), Rhode Island  (1636) as a colony tolerant of all religions and Connecticut (1639) for Congregationalists . England's North American holdings were further expanded by

22484-472: Was granted his own patent by Elizabeth in 1584. Later that year, Raleigh founded the Roanoke Colony on the coast of present-day North Carolina , but lack of supplies caused the colony to fail. In 1603, James VI of Scotland ascended (as James I) to the English throne and in 1604 negotiated the Treaty of London , ending hostilities with Spain. Now at peace with its main rival, English attention shifted from preying on other nations' colonial infrastructures to

22638-402: Was happening. The Germans then charged, driving the bewildered French back past their own trenches. Those who were enveloped by the fumes were not able to see each other half a yard apart. I have seen some of the wounded who were overcome by the sulphur fumes, and they were progressing favourably. The effect of the sulphur appears to be only temporary. The after-effects seem to be a bad swelling of

22792-456: Was issued by December 1915, and the PH helmet (effective against phosgene) was issued in early 1916. Although many French troops ran for their lives, others stood their ground and waited for the cloud to pass. Field Marshal Sir John French , Commander-in-Chief of the British Expeditionary Force, wrote,  ... I wish particularly to repudiate any idea of attaching the least blame to the French Division for this unfortunate incident. After all

22946-404: Was made to settle the country or establish possession. The coast of Australia had been discovered for Europeans by the Dutch in 1606 , but there was no attempt to colonise it. In 1770, after leaving New Zealand, James Cook charted the eastern coast, claimed the continent for Britain, and named it New South Wales . In 1778, Joseph Banks , Cook's botanist on the voyage, presented evidence to

23100-429: Was not divulged to the Sharif of Mecca , who the British had been encouraging to launch an Arab revolt against their Ottoman rulers, giving the impression that Britain was supporting the creation of an independent Arab state. The British declaration of war on Germany and its allies committed the colonies and Dominions, which provided invaluable military, financial and material support. Over 2.5 million men served in

23254-440: Was returning across the Atlantic, laden with treasure from the New World . At the same time, influential writers such as Richard Hakluyt and John Dee (who was the first to use the term "British Empire") were beginning to press for the establishment of England's own empire. By this time, Spain had become the dominant power in the Americas and was exploring the Pacific Ocean, Portugal had established trading posts and forts from

23408-427: Was supported by the British prime minister , William Gladstone , who hoped that Ireland might follow in Canada's footsteps as a Dominion within the empire, but his 1886 Home Rule bill was defeated in Parliament. Although the bill, if passed, would have granted Ireland less autonomy within the UK than the Canadian provinces had within their own federation, many MPs feared that a partially independent Ireland might pose

23562-481: Was the only global war fought between Britain and another imperial power during the Pax Britannica and was a resounding defeat for Russia. The situation remained unresolved in Central Asia for two more decades, with Britain annexing Baluchistan in 1876 and Russia annexing Kirghizia , Kazakhstan , and Turkmenistan . For a while, it appeared that another war would be inevitable, but the two countries reached an agreement on their respective spheres of influence in

23716-401: Was underpinned by the steamship and the telegraph , new technologies invented in the second half of the 19th century, allowing it to control and defend the empire. By 1902, the British Empire was linked together by a network of telegraph cables, called the All Red Line . The East India Company drove the expansion of the British Empire in Asia. The company's army had first joined forces with
