132-464: Lieutenant General Sir Joseph John Talbot Hobbs , KCB , KCMG , VD (24 August 1864 – 21 April 1938) was an Australian architect and First World War general. Hobbs was born in London , the son of Joseph and his wife Frances Ann Hobbs (née Wilson). Educated at St Mary's church school, Merton , Surrey , Hobbs joined the volunteer artillery in 1883. He also worked as draughtsman for
264-621: A major general in January. This division was in the thick of the fighting in the spring of 1917, and in September distinguished itself at Polygon Wood. The staff worked well together, and achieved a great victory. Hobbs was created both a Knight Commander of the Order of the Bath (KCB) and Knight Commander of the Order of St Michael and St George (KCMG) on 1 January 1918. At the end of April his division fought at
396-453: A German attack took Hope Post near Beaumont Hamel, which was lost to a British attack on 5 January. On the night of 10/11 January, a British attack captured the Triangle and Muck Trench, covering the flank of an attack on Munich Trench during the day; British troops edged forward over Redan Ridge for the rest of the month. A fall in temperature added to German difficulties, by freezing the mud in

660-583: A battalion of the 17th Division took a trench overlooking Saillisel and held it, despite German counter-attacks that continued on 9 February. On 21 and 22 February, Australian troops captured more of Stormy Trench despite rain, which made the ground even more "appalling", than before the freeze in January and early February. On 23 February, British and Australian troops on the south side of the Ancre, sent patrols forward to investigate fires seen in German trenches and discovered
792-784: A builder, John Hurst. In 1886, he emigrated with Hurst to Western Australia and established an architectural practice in Perth in 1887. Hobbs designed many of the well known public buildings in Perth and Fremantle , including the Weld Club , the Savoy Hotel and the Perth Masonic Lodge. Hobbs was treasurer of the Western Australian Institute of Architects in 1896, and later became the institute's president from 1909 to 1911. From 1905, he
924-635: A charge, permanently ruining the well. Much of the explosive used by the Germans ( Donarit , Westphalite and Perdit ) had the property of water-absorption so could be neutralised by dousing. Some British booby-trap patrols made German prisoners go first, who revealed traps rather than be blown up and British tunnellers removed 22,000 lb (10,000 kg) of explosives. (In some areas no booby-traps were found, as German divisional commanders had been allowed to choose whether to mine their areas and some refused.) Trees were to be cut down, wells polluted and
1056-693: A keen interest in the construction of war memorials, Hobbs was responsible for designing the Western Australian War Memorial in Kings Park , Perth, St George's College, Crawley and the Temperance and General and Royal Insurance buildings. Hobbs died at sea of a heart attack while en route to the unveiling of the Villers–Bretonneux Australian National Memorial . His body was returned from Colombo to Perth where he
1188-529: A leading part in the capture of Mont St Quentin, but Monash, in his The Australian Victories in France , stated that he was "concerned ... that the fine performance of the Fifth Division should not be underrated. The circumstances under which general Hobbs was called upon to intervene in the battle, at very short notice, imposed upon him, personally, difficulties of no mean order". One of his tasks it may be mentioned
1320-475: A return to the policy of unrestricted submarine warfare on 9 January 1917 and engineered the dismissal of the Chancellor Bethmann-Hollweg and other opponents of the policy the next day. The policy was to resume on 1 February, to sink 600,000 long tons (610,000 t) of shipping per month and knock Britain out of the war in five to twelve months. Optimistic claims by the navy were less important to
1452-694: A saving of 13 to 14 divisions, by withdrawing an average of 9.3 mi (15 km) to the Siegfriedstellung (Hindenburg Line). The German army was far from defeat but in 1916 had been forced back on the Somme and at Verdun, as had the Austro-Hungarian army in southern Russia. At the Chantilly Conference of November 1916 the Allies agreed to mount another general offensive. The Anglo-French contribution

The Germans prepared a 35-day Alberich timetable; infrastructure in the salient was to be destroyed and buildings demolished from 9 February – 15 March. Booby-traps were devised with delayed-action fuzes used a striker on a spring, held back by a wire. Acid ate through the wire, to release the striker and detonate the explosive. A number of devices with such fuzes were planted in bunkers but most booby-traps had simple pressure detonators. Wires were attached to useful items like stove chimneys and loot; trip-wires on

Next day, parties of Germans at Beugny in the Riegel III Stellung fought until nightfall then slipped away. A party at Vaulx Vraucourt was surprised (while some were shaving) and driven back to Lagnicourt. On 20 March, an Australian attack on Noreuil failed with 331 casualties and an attack on Croisilles
2244-400: The Siegfriedstellung (Hindenburg Line) begin. Ludendorff rejected the proposal next day but British attacks on the 1st Army, particularly the action of Miraumont/Battle of Boom Ravine (17–18 February), caused Rupprecht on the night of 22 February, to order a preliminary withdrawal of about 4 mi (6.4 km) between Essarts and Le Transloy to Riegel I Stellung . On 24 February,

Another two-trench system ( Siegfried II Stellung ) was planned near the artillery reserve positions, which were about 3,000 yd (1.7 mi; 2.7 km) behind
2508-463: The Siegfriedstellung (Hindenburg Line). The front-holding divisions, which had been worn down by British attacks, were withdrawn behind the Siegfriedstellung (Hindenburg Line). On 17 March, the German troops at the north end of the Bapaume Salient withdrew swiftly, as there were no intermediate lines corresponding to the Riegel III Stellung north of Achiet le Grand.

Construction was organised by Rupprecht and Kuhl; when the plans were ready the line was divided into sectors and officers from the General Staff, gunners and engineers were appointed to oversee construction, which
2772-764: The 1st Army and plans for a counter-stroke had been abandoned for lack of troops. The emergency in Russia caused by the Brusilov Offensive , the entry of Romania into the war and the French counter offensive at Verdun had already overstretched the German army.

Ernst von Wrisberg ( de ) Deputy Minister of the Prussian Ministry of War , responsible for raising new units, had grave doubts about the wisdom of this increase in the army but was over-ruled by Ludendorff. The German army had begun 1916 equally well-provided for in artillery and ammunition, massing 8.5 million field and 2.7 million heavy artillery shells for
3564-468: The 1st Army section of the Siegfriedstellung (Hindenburg Line) from Quéant, where it met the site of the Wotanstellung (Wotan Line) to Bellicourt north of St Quentin, should have another position built 2,000–3,000 yd (1.1–1.7 mi; 1.8–2.7 km) in front of the new position, which would become the artillery protection position ( Artillerieschutzstellung ) behind the revised front system;
3696-481: The 1st and 2nd Army commanders on the Somme front opposed a retirement. Resources continued to be directed to the Somme defences during January and February and on 6 February, the 1st Army HQ requested three divisions and 15,000 labourers to work on new positions, to implement the Wotan–Siegfried–Riegel plan, a partial withdrawal to a line from Arras to Sailly.

Next day, German rear guards inflicted 174 casualties on Australian troops near Loupart Wood and forced British troops back out of Irles with artillery-fire. A British attack on Puisieux on 26 February took all day and ended in hand-to-hand fighting. Next day troops of Prussian Foot Guard Regiment 5 withdrew from Thilloy, completing

Over the winter, German deception operations were conducted and indications of an offensive through Switzerland diverted French attention at the end of 1916. The British were occupied by reports of troops and heavy artillery moving into Flanders and increased numbers of agent reports of troop movements from Lille , Tourcoing and Courtrai .

Roads built on causeways over marshy ground between the river and canal, caused water to form pools 0.5 mi (0.80 km) wide, making crossings practical only at the causeways. The bridges over the rivers Germaine, Omignon, Cologne, Tortille and the Canal du Nord were also destroyed and huge craters blown in crossroads,

5544-475: The Somme and the Aisne were considered but the manpower and equipment shortage meant that even smaller attacks risked using up reserves needed for defence against the expected Anglo-French spring offensives. Local attacks like those at Bouchavesnes and La Maisonette on the Somme in late 1916, which could be mounted without reinforcements, were all that could be considered. Ludendorff accepted the analysis that no offensive

Movement behind the German front was made difficult by constant Anglo-French artillery harassing-fire, which added to equipment shortages by delaying deliveries by rail and interrupting road maintenance. Destruction, capture, damage, wear and defective ammunition had caused 1,068 of 1,208 field guns and 371 of 820 heavy guns to be out of action by

On 2 January, Nivelle instructed the Aéronautique Militaire to co-operate with the British to investigate German defensive systems that spies and repatriated civilians had reported. Not until 26 January, did a British intelligence summary report a new line of defence between Arras and Laon. In February, attempts to send more aircraft to reconnoitre

Behind the Fifth and Fourth army fronts, the course of the Hindenburg Line
6072-535: The Somme was suspended. Defeats inflicted south of the Somme by the French Tenth Army (10–21 October) led to the sacking of Bronsart von Schellendorf, the 2nd Army chief of staff. Hindenburg and Ludendorff demanded domestic changes to complement their new strategy. German workers were to be subjected to an Auxiliary Service Law ( Hilfsdienstgesetz ) that from November 1916, subjected all Germans from 16 to 50 years old to compulsory service. The new programme

On 10 March, the Fifth Army took Grévillers Trench and Irles in a methodical attack, which overwhelmed the German defence and took 215 prisoners. Fires could be seen behind Bapaume, with more visible behind the Riegel III Stellung and British military intelligence reported that the headquarters of Rupprecht had been moved to Mons; civilians were known to have been evacuated along with supply dumps and artillery. The Riegel II Stellung

Behind the old British front line, the thaw badly affected roads, which had been in a very poor condition at the end of 1916, many were closed and others were limited to horse-drawn traffic. Railway transport was even worse affected, with Boulogne harbour blocked, the number of trains and wagons on the northern French railways far short of British requirements, the lines being congested and subject to traffic restrictions. Supply difficulties had also begun to increase on

Troops for the extra divisions of the expansion ordered by Hindenburg and Ludendorff could be found by combing out rear-area units but most would have to be drawn from the pool of replacements, which had been depleted by the losses of 1916 and although new classes of conscripts would top up the pool, casualty replacement would become much more difficult once the pool had to maintain a larger number of divisions.

The practice of rigidly defending front-line trenches, regardless of casualties was abolished, in favour of a mobile defence of the fortified areas being built over the autumn and winter of 1916–1917. Allgemeines über Stellungsbau (Principles of Field Fortification) was published in January 1917, in which instructions were given for

The German army returned 125,000 skilled workers to the war economy and exempted 800,000 workers from conscription, from September 1916 to July 1917. Steel production in February 1917 was 252,000 long tons (256,000 t) short of expectations and explosives production was 1,100 long tons (1,100 t) below the target, which added to

Front line troops were allowed to move away from fire, preferably by advancing into no man's land but moves to the flanks and rear were also allowed. When front-line garrisons and their supports were unable to hold or recapture

By the end of the Battle of Morval (25–28 September) Rupprecht had no reserves left on the Somme. During September, the Germans sent another thirteen fresh divisions to the British sector and scraped up troops wherever they could be found. The German artillery fired 213 train-loads of field artillery shells and 217 train-loads of heavy ammunition, yet

The artillery deficit was only slowly improved by the plan of General Max von Gallwitz to centralise the command of the remaining artillery for counter-battery fire and to use reinforcements of aircraft to increase the amount of observed artillery fire, which had little effect on Allied air superiority but did eventually increase the accuracy and efficiency of German bombardments. The 2nd Army had been starved of reinforcements in mid-August to replace exhausted divisions in
9504-483: The evidence of German demolitions, indicated that a longer retirement was planned but the existence of three German reserve lines 5–6 mi (8.0–9.7 km) behind the front line, made a local German retirement seem more likely than a longer one. On 13 March, a document revealing the plan and the code-name Alberich dated 5 March, was found in Loupart Wood. On 24 February Lieutenant-General Hubert Gough defined

When complete the various positions had a depth of 6,000–8,000 yd (3.4–4.5 mi; 5.5–7.3 km) and the original Hindenburg Line had become an intermediate line ( Siegfried I Zwischenstellung ). Work began on another defensive position in
9768-513: The front-line, they were to defend positions even if surrounded, to give time for a counter-attack by reserve divisions. When an immediate counter-attack ( Gegenstoss ) from behind the defensive position was not possible, a deliberate counter-attack ( Gegenangriff ) was to be planned over several days. Two schools of thought emerged over the winter; the principal authors of the new training manual, Colonel Max Bauer and Captain Hermann Geyer of
9900-671: The front. The declaration of war by Romania had placed additional strain on the German army and war economy. The Hindenburg Line, built behind the Noyon Salient , was to replace the old front line as a precaution against a resumption of the Battle of the Somme in 1917. By devastating the intervening ground, the Germans could delay a spring offensive in 1917. A shortened front could be held with fewer troops and with tactical dispersal, reverse-slope positions , defence in depth and camouflage , German infantry could be conserved. Unrestricted submarine warfare and strategic bombing would weaken
10032-562: The line already had 1,200 dug-outs to accommodate 14,000 men , which was sufficient to shelter local reserves. The new line would be similar but on reverse slopes, have dugouts for 24,000 men and be ready by 15 March. The existing artillery positions were scrapped and the artillery sited to dominate ground useful for the assembly of assault-troops, such as the La Vacquerie plateau. Rupprecht refused to delay implementation of Operation Alberich (the Alberich Bewegung ) but having inspected
10164-477: The line were hampered by mist, snow, rain, low cloud and an extremely determined German air defence. British air reconnaissance discovered diggings between Drocourt and Vitry en Artois at the end of January and on 15 February, found a line between Quéant and Etaing. The British were able to trace the new line (named the Drocourt–Quéant Switch) south to Bellicourt on 15 February and St Quentin on 25 February,
10296-502: The new Ausbildungsvorschrift für die Fusstruppen im Kriege (Training Manual for Foot troops in War) of March 1917. Training schools were established to prepare German commanders and courses began in February 1917. British and French plans for 1917 were agreed at an Allied conference at Chantilly from 15–16 November 1916. Existing operations were to continue over the winter, fresh troops arriving in front-line units were to be trained and in
10428-506: The new supreme command) ordered an end to attacks at Verdun and the dispatch of troops from there to Romania and the Somme front. On 5 September, proposals for a new shorter defensive position to be built in France were requested from the commanders of the western armies, who met Hindenburg and Ludendorff at Cambrai on 8 September. The western front commanders were told that no reserves were available for offensive operations, except those planned for Romania. Generalleutnant Georg Fuchs, one of
10560-560: The new year with 21 divisions was discussed on 19 December but it was considered that such a force could not achieve a decisive result. An OHL memorandum of 5 January noted that offensive preparations by the French and British were being made all along the Western Front to keep the site of a spring offensive secret. It was considered that the Somme front, the area between Arras and Lille, the Aisne front, Lorraine and Flanders were particularly threatened. Prisoner interrogation, postal analysis, espionage and air reconnaissance were used to identify
10692-569: The number of divisions on the Aisne front to 38 by early April. The Hindenburg Line was attacked several times in 1917, notably at St Quentin, Bullecourt, the Aisne and Cambrai and was broken in September 1918 during the Hundred Days Offensive . In August 1916 the German armies on the Somme had been subjected to great strain; the IX Reserve Corps had been "shattered" in the defence of Pozières. Ten fresh divisions had been brought into
10824-912: The original position and the rear-guards retired next day from Nurlu and Bertincourt as soon as British troops appeared, then counter-attacked British cavalry around Poeuilly on 22 March. A large counter-attack was mounted on the French front on 22 March, which forced French cavalry and cyclists back over the Crozat Canal with many casualties but began too soon to ambush a large force that included artillery, as had been intended. A Booby-trap exploded in Bapaume town hall on 25 March, killing Australian troops and two French Deputies; French civilians were left behind at Bouvincourt, Vraignes and Tincourt on 26 March and Villers Faucon, Saulcourt and Guyencourt were lost on 27 March, to attacks by British cavalry and armoured cars. Supplies of armour-piercing bullets had been sent forward by
10956-421: The output of propellants, since the manufacture of ammunition without sufficient propellant fillings was as wasteful of resources as it was pointless; Hindenburg and Ludendorff wanted firepower to replace manpower and ignored the principle. To meet existing demand and to feed new weapons, Hindenburg and Ludendorff wanted a big increase in propellant output to 12,000 long tons (12,000 t) a month. In July 1916,
11088-461: The output target had been raised from 7,900 to 9,800 long tons (8,000 to 10,000 t), which was expected to cover existing demand and the extra 2,000 long tons (2,000 t) of output demanded by Hindenburg and Ludendorff could never match the doubling and trebling of artillery, machine-guns and trench mortars. The industrial mobilisation needed to fulfil the Hindenburg Programme increased demand for skilled workers, Zurückgestellte (recalled from
11220-481: The plan and 10,000–15,000 French civilians were to be left behind in them, while 150,000 able-bodied civilians were to be evacuated to work in the rest of occupied France and Belgium. A 35-day timetable for the demolition plan was prepared to be followed by two marching days for the troops on the flanks of the area, three for the troops between Nauroy and Coucy le Chateau and four marching days for those between St Quentin and La Fère. Defensive positions held by
11352-567: The pressure on Ludendorff to retreat to the Hindenburg Line. Despite the shortfalls, by the summer of 1917, the Westheer artillery park had increased from 5,300 to 6,700 field guns and from 3,700 to 4,300 heavy guns, many being newer models of superior performance. Machine-gun output enabled each division to have 54 heavy and 108 light machine-guns and for the number of Maschinengewehr-Scharfschützen-Abteilungen (MGA, machine-gun sharpshooter detachments) to be increased. The greater output
11484-457: The probable sites of Anglo-French offensives. March was considered the earliest that the Anglo-French could attack, with a possible delay if a Russian offensive was also planned. The chief of staff of Army Group Rupprecht, Generalleutnant Hermann von Kuhl issued a survey of offensive possibilities on 15 January. A German breakthrough attempt was rejected for lack of means and the consequences of failure. Limited-objective attacks at Loos, Arras,
11616-422: The rear edge of the German defences would achieve the breakthrough. The infantry advance was to reach the German heavy artillery in one attack and then widen the breach with lateral attacks. A strategic reserve would then move through the gap and destroy the German reserves in open warfare. The original French attacks between the Somme and Oise were reduced in size and the secondary attack between Soissons and Rheims
11748-400: The rear of the defensive areas. Within the new forward zones, battlezones and rearward battle zones, the chain of command was streamlined by making corps headquarters into Gruppen (groups), responsible for the administrative tasks in an area into which divisions would be moved for periods, before being withdrawn to rest, train and be brought up to strength. Command of areas rather than units
11880-482: The rear was not followed. Artillery observation posts were built in the front-trench system or in front of it. Trenches had been dug near a crest, on a forward slope or at the rear of a reverse slope, which replicated the obsolete positions being abandoned. The 1st Army commander, General Fritz von Below and his Chief of Staff Colonel Fritz von Loßberg rejected this layout since smoke and dust would make artillery observation from such positions impossible. They urged that
12012-412: The recapture of lost positions by counter-attacks, a practice that had already been forced on the German armies on the Somme. On 15 September Generalfeldmarschall Crown Prince Rupprecht , commander of the northern group of armies, was ordered to prepare a rear defensive line and on 23 September work on the new Siegfriedstellung (Siegfried Position/Hindenburg Line) began. On 21 September, after
12144-438: The retirement to the Riegel I Stellung . The German withdrawal was helped by a thaw, which turned roads behind the British front into bogs and by disruption to the Allied railways that supplied the Somme front. On the night of 12 March, the Germans withdrew from the Riegel I Stellung between Bapaume and Achiet le Petit, while small parties of troops sent up flares to mislead the British, who were preparing an attack. It took
12276-405: The role and its authority. In June 1986, the three-star position Vice Chief of the Defence Force (VCDF) was created. As with CDF, this position rotates between the forces. Lieutenant General John Baker was the first army officer to occupy the position (October 1992 – April 1995). A third three-star position, Chief of Capability Development Group (CCDG), which also rotates between the forces,
12408-543: The spring the front of attack was to be broadened, from the Somme to Arras and the Oise. The front of attack was to be about 50 mi (80 km) long, with two French surprise attacks near Rheims and in Alsace, to begin after the main attacks, to exploit German disorganisation and lack of reserves. The Allies expected to have 168 divisions against 129 German divisions, for the co-ordinated offensives. A British operation in Flanders
12540-430: The stairs of dugouts were connected to bundles of hand-grenades. On some roads, heavy-artillery shells were buried with contact-fuzes, which would only be triggered by the weight of a lorry. British engineers and tunnelling companies scoured areas as they were occupied and disabled many of the explosives. Roads were flooded by destroying drains and water-courses; wells sabotaged by drilling a shaft next to them and exploding
12672-412: The strain on the Westheer and realise a surplus for offensives on other fronts. Hindenburg and Ludendorff ordered the creation of another 22 divisions, to reach 179 divisions by early 1917. The men for the divisions created by Falkenhayn had come from reducing square divisions with four infantry regiments to triangular divisions with three regiments, rather than a net increase in the number of men in
12804-476: The trench lines. Where the lay of the land gave observation from behind the system, it was built on reverse slopes (a Hinterhangstellung ), with a short field of fire for the infantry, according to the experience of the Western Front defensive battles of 1915 and 1916, when forward-slope positions had been smashed by observed Franco-British artillery-fire. In much of the new position, the new principle of reverse-slope positions with artillery-observation posts to
12936-459: The volunteer artillery in Perth as a gunner, was commissioned in 1889, and rose to the command of the 1st (Western Australian) Field Battery in 1903. In 1906 he was a lieutenant colonel commanding a Western Australian mixed brigade, and in 1913 a colonel commanding the 22nd Infantry Brigade. On four occasions he went to England and did intensive courses in artillery training with the British Army. He
13068-450: The war, Germany had imported nitrates for propellant manufacture and only the discovery before the war of the Haber process for the synthesis of nitrates from atmospheric nitrogen, enabled Germany to produce explosives while blockaded. Developing the process and building factories to exploit it took time. Under Falkenhayn, the procurement of ammunition and the weapons to fire it, had been based on
13200-526: The west, succeeded despite the weather and the Germans being forewarned. On the Fourth Army front, fewer attacks took place while the French line was being taken over in stages, southwards to the Amiens–Roye road. On 27 January, the 29th Division took 368 prisoners in an advance of only 400 yd (370 m) and on 1 February, an Australian attack on Stormy Trench was repulsed by a German counter-attack. A second attack on 4 February succeeded. On 8 February,
13332-401: The winter and the transfer of divisions from Russia, 154 German divisions the Western Front were confronted by 190 French , British and Belgian divisions, many of which were bigger than the German equivalents. The Wotan–Siegfried–Riegel plan would reduce the front by 8.1 mi (13 km) and need six fewer front-holding divisions, compared to a shortening of 28 mi (45 km) and
13464-693: The winter of 1916–1917 on the Western Front in France during the First World War . The line ran from Arras to Laffaux , near Soissons on the Aisne . In 1916, the Battle of Verdun and the Battle of the Somme left the German western armies ( Westheer ) exhausted and on the Eastern Front , the Brusilov Offensive had inflicted huge losses on the Austro-Hungarian armies and forced the Germans to take over more of
13596-637: The winter, with only 60 per cent of the programme expected to be fulfilled by the summer of 1917. The German Friedensangebot (peace initiative) of December 1916 had been rejected by the Entente and the Auxiliary Service Law of December 1916, intended further to mobilise the civilian economy, had failed to supply the expected additional labour for war production. The retirement to the Hindenburg Line ( Alberich Bewegung /Operation Alberich/Alberich Manoeuvre) took place from February to March 1917. News of
13728-518: Was "he was not only a soldier, he was also a great citizen, and a great Christian gentleman ... who knew none other than the straight path". The Lieut. General Sir J. J. Talbot Hobbs Memorial , better known as the Talbot Hobbs memorial , was proposed and constructed just prior to the Second World War. The memorial is made of Donnybrook stone with a bronze bust of Hobbs on top, and placed against
13860-476: Was Colonel William Throsby Bridges . The first Australian lieutenant general to occupy this position was Sir Brudenell White , from 1 June 1920. Since August 1940, this position, and its successor (Chief of Army), have been held by Australian lieutenant generals. In March 1958, the role of Chairman, Chiefs of Staff Committee was created, but with no command authority. This was initially occupied by Lieutenant General Sir Henry Wells (March 1958 – March 1959), and
13992-423: Was abandoned by 18 March and next day Boyelles and Boiry Becquerelle were evacuated. The withdrawal went straight back to the Siegfriedstellung (Hindenburg Line) except for outposts at Hénin sur Cojeul, St Martin sur Cojeul and the west end of Neuville Vitasse. Numerous raids were mounted on British outposts during 20 and 21 March. The Riegel I Stellung was abandoned north of the Ancre, along with part of
14124-399: Was also agreed, to begin several weeks after the main offensives further south. Joffre was replaced by Nivelle on 13 December, who proposed a much more ambitious strategy, in which the plan for a resumption of Anglo-French attacks either side of the Somme battlefield of 1916 was retained but the offensive on the Aisne was converted to a breakthrough offensive, to be followed by the commitment of
14256-421: Was also introduced in divisions, with command of regiments devolved to the front battalion commander (KTK Kampftruppenkommandeur ), which reduced the chain of command from five to two posts. The value of ground was to be determined by its importance to a defensive position. Where the lay of the land gave the defender a tactical advantage, by which an attacker could be defeated with the minimum of casualties to
14388-428: Was conducted by canal barge and railway, which carried 1,250 trainloads of engineering stores, although the building period from October 1916 to March 1917 meant that only about eight trains a day were added to normal traffic. Mass-production techniques were used to produce items for the position. Steel-reinforced concrete dug-outs for infantry squads and artillery-observation posts were standard designs and all woodwork
14520-510: Was created in 2003. Lieutenant General John Caligari was the final officer of three-star rank to hold the position before it was disestablished in 2016 In September 2007, a fourth three-star position, Chief of Joint Operations , was created. There are two other permanent three-star positions in the Australian Defence Force, Chief of Navy and Chief of Air Force . There are also a number of other three-star-equivalent positions in
14652-410: Was equipped with dugouts for most of the front garrison. Fields of barbed wire up to 100 yd (91 m) deep, were fixed with screw pickets in three belts 10–15 yd (9.1–13.7 m) wide and 5 yd (4.6 m) apart, in a zig-zag so that machine-guns could sweep the sides, placed in front of the trench system. Artillery observation posts and machine-gun nests were built in front of and behind
14784-437: Was expected to take five months. The defences were built by German construction companies, who brought skilled workmen to fabricate ferro concrete emplacements, while 12,000 German and 3,000 Belgian labourers and 50,000 mainly Russian prisoners of war dug the trenches. The building works absorbed most of the cement, sand and gravel production of occupied France and Belgium plus that of west Germany. Transport of materials
14916-510: Was forced to retire with 174 casualties. The Fifth Army divisions advanced with patrols until they met German resistance, then prepared deliberate attacks, some of which were forestalled by German withdrawals, which by 26 February, apart from some small detachments, had abandoned the ground west of the Riegel I Stellung . British engineers improvised sleds to move guns and wagons, with pack-mules being used to carry food and ammunition and on 8 March, ammunition lorries were able to move forward in
15048-415: Was found to be empty between Bapaume and Achiet le Petit on the night of 12 March but next day an attack on Bucquoy failed with 574 casualties. The German document found in Loupart Wood dated 5 March, containing details of the Alberich Bewegung (Operation Alberich), showed that Loupart Wood had been abandoned a day early. On the night of 14 March, patrols found that the Germans had withdrawn from part of
15180-472: Was further away and the winter weather was exceptionally bad, which grounded aircraft and made air observation unreliable. On 11 December, a reconnaissance in the area of Marcoing reported nothing unusual, despite flying over the new diggings. German fighter opposition in the area became much worse, with more aircraft and the arrival in service of superior aircraft types in the late summer of 1916. Three intermediate defensive lines begun in late 1916, much closer to
15312-571: Was given a military and state burial. Hobbs was a short and slight man, whose civilian life was that of a successful citizen who had a full realisation of his responsibilities to the society of which he was a member. Hobbs was capable, self-sacrificing and measured his life by high standards. Monash said of Hobbs that he "succeeded fully as the Commander of a Division by his sound common sense and his sane attitude towards every problem that confronted him". The eulogy of Lieutenant General Sir Brudenell White
15444-404: Was insufficient to equip the new divisions; existing divisions, which still had two artillery brigades with two regiments each, lost a regiment and the brigade headquarters, leaving three regiments. Against the new scales of equipment, British divisions in early 1917 had 64 heavy and 192 light machine-guns and the French 88 heavy and 432 light machine-guns. Hindenburg and Ludendorff forced
15576-458: Was intended to create a trebling of artillery and machine-gun output and a doubling of munitions and trench mortar production. Expansion of the army and output of war materials caused increased competition for manpower between the army and industry. In early 1916, the German army had 900,000 men in recruit depots and another 300,000 due in March when the 1897 class of conscripts was called up. The army
15708-417: Was made to a pattern. The line was 90 mi (140 km) long and built for a garrison of twenty divisions, one every 4.5 mi (7.2 km). Telephone cables were deeply buried and light railways built to carry supplies to the defences. The position had two trenches about 200 yd (180 m) apart, with sentry garrisons to occupy the front trench. The main line of defence was the second line, which
15840-517: Was possible. On a visit to Kuhl on 20 January, Fuchs concluded that Allied superiority was so great that the German army could not forestall the Anglo-French with an attack or stop them attacking elsewhere. The army could not withstand another battle like the Somme; work on defences there was futile and would exhaust the troops for nothing. On 29 January, Ludendorff ruled that a withdrawal could not be ordered on political as well as military grounds, then on 31 January, discussed withdrawal with Kuhl, while
15972-502: Was reinforced to become the main offensive. The Nivelle Offensive was planned to begin with a British attack on the Bapaume salient in early April 1917, to assist the main French attacks a week later by holding German troops on the Arras front and diverting reserves from the Aisne. German reconnaissance aircraft surveyed all of the Western Front over the winter of 1916–1917 to look for signs of Anglo-French offensive preparations. The design of
16104-433: Was repulsed. A German counter-attack to recover Beaumetz was mounted on 23 March and got into the village before being forced to withdraw; the attack was repeated next day but only one party reached the village. Lagnicourt was lost on 26 March and a counter-attack from Noreuil repulsed, then a British attack on Bucquoy was defeated. The 2nd Army conducted the withdrawal with the line-holding divisions, which were fresher than
16236-467: Was rotated through the three services, hence (briefly) providing a three-star position available to army officers. In 1968 this became a four-star position. It was replaced in February 1976 by a new position, Chief of Defence Force Staff, with command authority over the Australian Defence Force , and in October 1984 the position was renamed Chief of the Defence Force (CDF) to more clearly reflect
16368-631: Was senior partner in the firm of architects, Hobbs, Smith & Forbes. Hobbs also designed a number of private residences. The first of these is believed to be Samson House in Fremantle, an example of late 19th century colonial style, which was built in two stages between 1888 and 1890. The house is registered with the National Trust , and is in the Register of the National Estate . In 1887, Hobbs joined
16500-434: Was so flush with men that plans were made to demobilise older Landwehr classes and in the summer, Falkenhayn ordered the raising of another 18 divisions, for an army of 175 divisions. The costly battles at Verdun and the Somme had been much more demanding on German divisions and they had to be relieved after only a few days in the front line, lasting about 14 days on the Somme. A larger number of divisions might reduce
16632-400: Was struck down with dysentery and invalided to Cairo despite his protests. Hobbs was then promoted brigadier general and made a Companion of the Order of the Bath (CB). In March 1916 he went with the 1st Australian Division to France, and was in command of the Australian artillery when Pozières was captured. In December 1916 he assumed command of the 5th Australian Division and was made
16764-524: Was superseded by General Robert Nivelle , the "Chantilly strategy" was altered. The French returned to a policy of decisive battle, with a breakthrough to be achieved within 24–48 hours, leading to the "total destruction of active enemy forces by manoeuvre and battle". Successive attacks in a methodical battle were dropped and continuous thrusts were substituted, to deprive the Germans of time to reinforce and strengthen their defences. A large amount of heavy artillery fire up to 5.0 mi (8 km) deep, to
16896-406: Was the crossing of the Somme in the face of strong opposition, and when Hobbs sent a message to the men of his war-worn division on its beginning a rest period on 8 September, he was able to say that they had "earned imperishable fame for their gallantry and valour". It was but a short rest, for they were in the line again later on in the same month, and Hobbs was making careful plans for the attack on
17028-483: Was thus thoroughly equipped when war broke out and, on 8 August 1914 was selected by Major General William Bridges to command the 1st Australian Divisional Artillery. After training in Egypt, he was at the landing at Gallipoli on 25 April 1915 and was soon ashore searching for positions for his guns. Hobbs clashed with Bridges over the placement of the guns. Hobbs was in command of the artillery until 9 November 1915 when he
17160-501: Was to be a resumption of the Somme offensive with much larger forces, extending the attack north to Arras and south to the Oise, followed by a French attack between Soissons and Rheims. The British were to attack the salient that had formed between Bapaume and Vimy Ridge with two armies and the French with three armies from the Somme to Noyon. The attacks were to be made on the broadest possible fronts and advance deep enough to threaten German artillery positions. When Marshal Joseph Joffre
17292-497: Was to be built behind the 1915 battlefields of Loos, Vimy and Arras and the 1916 battlefield of the Somme. The Siegfriedstellung (Siegfried Position, known to the British as the Hindenburg Line) was to be built across the base of the Noyon Salient , from Neuville Vitasse near Arras, through St Quentin and Laon, the Aisne east of Soissons to Cerny en Laonnois on the Chemin des Dames ridge. The Hundingstellung ( Hunding Position)
17424-590: Was to run from Péronne to Etain, north-east of Verdun behind the Champagne battlefields of 1915. The Michelstellung (Michel Position) was to cover Etain to Pont-à-Mousson behind the St Mihiel Salient. The new fortified areas were intended to be precautionary measures ( Sicherheitskoeffizient ) built to be used as rallying-positions ( Eventual-Stellungen , similar to ones built on the Russian front) and to shorten
