The National Historical Park is under the jurisdiction of the National Park Service and protects 970 acres (392.5 ha) in and around the Massachusetts towns of Lexington , Lincoln , and Concord . Park visitor centers are located at
254-533: A brief skirmish at Lexington, followed by the full-scale Battles of Lexington and Concord. British troops suffered around 300 casualties before withdrawing to Boston , which was then besieged by the militia. In May 1775, 4,500 British reinforcements arrived under Generals William Howe , John Burgoyne , and Sir Henry Clinton . On June 17, they seized the Charlestown Peninsula at the Battle of Bunker Hill ,
381-483: A broad, sluggish inlet of the sea, with many marshes along its side, widening steadily into its great estuary, Delaware Bay . The Delaware River constitutes the boundary between Delaware and New Jersey. The Delaware–New Jersey border is actually at the easternmost river shoreline within the Twelve-Mile Circle of New Castle , rather than at mid-river, mid-channel or thalweg , so small portions of land lying west of

As a result of disruption following the French and Indian War , American Revolutionary War , and the later Indian removals from
635-768: A customs vessel in the June 1772 Gaspee Affair , then came to a head in 1773. A banking crisis led to the near-collapse of the East India Company , which dominated the British economy; to support it, Parliament passed the Tea Act , giving it a trading monopoly in the Thirteen Colonies . Since most American tea was smuggled by the Dutch, the act was opposed by those who managed the illegal trade, while being seen as yet another attempt to impose
762-569: A day from the Delaware and its upstream tributaries. The Delaware River has been attached to areas of high pollution . The Delaware River in 2012 was named the 5th most polluted river in the United States, explained by PennEnvironment and Environment New Jersey. The activist groups claim that there is about 7–10 million pounds of toxic chemicals flowing through the waterways due to dumping by DuPont Chambers Works. PennEnvironment also claims that
889-500: A depth of 40 ft (12 m). There is an effort underway to deepen the 102.5-mile stretch of this federal navigation channel, from Philadelphia and Camden to the mouth of the Delaware Bay to 45 feet. The Delaware River port complex refers to the ports and energy facilities along the river in the tri-state PA - NJ - DE Delaware Valley region. They include the Port of Salem ,
1016-542: A frontal assault in which they suffered over 1,000 casualties. Dismayed at the costly attack which had gained them little, Gage appealed to London for a larger army, but instead was replaced as commander by Howe. On June 14, 1775, Congress took control of Patriot forces outside Boston, and Congressional leader John Adams nominated Washington as commander-in-chief of the newly formed Continental Army . On June 16, Hancock officially proclaimed him "General and Commander in Chief of
1143-450: A logistically challenging and dangerous operation. Meanwhile, the Hessians were involved in numerous clashes with small bands of Patriots and were often aroused by false alarms at night in the weeks before the actual Battle of Trenton . By Christmas they were tired, while a heavy snowstorm led their commander, Colonel Johann Rall , to assume no significant attack would occur. At daybreak on

#17328528348551524-553: A rearguard. Howe met with a delegation from the Second Continental Congress at the September Staten Island Peace Conference , but it failed to conclude peace, largely because the British delegates only had the authority to offer pardons and could not recognize independence. On September 15, Howe seized control of New York City when the British landed at Kip's Bay and unsuccessfully engaged
1651-583: A result of the failure of a controversial plan to build a dam on the Delaware River at Tocks Island , just north of the Delaware Water Gap to control water levels for flood control and hydroelectric power generation. The dam would have created a 37-mile (60 km) lake in the center of present park for use as a reservoir. Starting in 1960, the present-day area of the Recreation Area was acquired for
1778-842: A riot started in Boston when the authorities seized the sloop Liberty on suspicion of smuggling. Tensions escalated further in March 1770 when British troops fired on rock-throwing civilians, killing five in what became known as the Boston Massacre . The Massacre coincided with the partial repeal of the Townshend Acts by the Tory-based North Ministry , which came to power in January 1770 and remained in office until 1781. North insisted on retaining duty on tea to enshrine Parliament's right to tax
1905-643: A second attack captured Fort Mifflin on November 16, while Fort Mercer was abandoned two days later when Cornwallis breached the walls. His supply lines secured, Howe tried to tempt Washington into giving battle, but after inconclusive skirmishing at the Battle of White Marsh from December 5 to 8, he withdrew to Philadelphia for the winter. On December 19, the Americans followed suit and entered winter quarters at Valley Forge ; while Washington's domestic opponents contrasted his lack of battlefield success with Gates' victory at Saratoga, foreign observers such as Frederick
2032-475: A struggle with Britain, but also split between American Patriots and American Loyalists. Patriots generally supported independence from Britain and a new national union in Congress, while Loyalists remained faithful to British rule. Estimates of numbers vary, one suggestion being the population as a whole was split evenly between committed Patriots, committed Loyalists, and those who were indifferent. Others calculate
2159-654: A threat to liberty in general. This led to increased sympathy for the Patriot cause locally, in the British Parliament, and in the London press. Throughout the 18th century, the elected lower houses in the colonial legislatures gradually wrested power from their governors. Dominated by smaller landowners and merchants, these assemblies now established ad-hoc provincial legislatures, variously called congresses, conventions, and conferences, effectively replacing royal control. With

Most of the larger bridges are tolled only westbound, and are owned by the Delaware River and Bay Authority , Delaware River Port Authority , Burlington County Bridge Commission or Delaware River Joint Toll Bridge Commission . After New York City built 15 reservoirs to supply water to the city's growing population, it was unable to obtain permission to build an additional five reservoirs along
2540-401: Is also one of the first times that the colonies were referred to as "United States", rather than the more common United Colonies . On July 2, Congress voted for independence and published the declaration on July 4. At this point, the revolution ceased to be an internal dispute over trade and tax policies and had evolved into a civil war, since each state represented in Congress was engaged in
2667-450: Is an important part of the Delaware River's history, adding to its diverse cultural legacy. The magnitude of the commerce of Philadelphia has made the improvements of the river below that port of great importance. Small improvements were attempted by Pennsylvania as early as 1771. Commerce was once important on the upper river, primarily prior to railway competition of 1857. The Delaware Water Gap National Recreation Area came about as

#17328528348552794-624: Is named in honor of Thomas West, 3rd Baron De La Warr (1577–1618), an English nobleman and the Virginia colony's first royal governor , who defended the colony during the First Anglo-Powhatan War . Lord de la Warr waged a punitive campaign to subdue the Powhatan after they had killed the colony's council president, John Ratcliffe , and attacked the colony's fledgling settlements. Lord de la Warr arrived with 150 soldiers in time to prevent
2921-402: Is working to try to address the issue of flooding along the river. As the past few years have seen a rise in catastrophic floods, most residents of the river basin feel that something must be done. The local governments have worked in association with FEMA to address many of these problems, however, due to insufficient federal funds, progress is slow. A number of oil spills have taken place in
3048-614: The Appalachian Mountains also avoided the cost of an expensive military occupation. The Royal Proclamation of 1763 was designed to achieve these aims by refocusing colonial expansion north into Nova Scotia and south into Florida , with the Mississippi River as the dividing line between British and Spanish possessions in America. Settlement was tightly restricted beyond the 1763 limits, and claims west of this line, including by Virginia and Massachusetts , were rescinded despite
3175-490: The Army Corps of Engineers through eminent domain . Between 3,000 and 5,000 dwellings were demolished, including historical sites, and about 15,000 people were displaced by the project. Because of massive environmental opposition, dwindling funds, and an unacceptable geological assessment of the dam's safety, the government transferred the property to the National Park Service in 1978. The National Park Service found itself as
3302-472: The Battle of Brandywine on September 11, then allowing him to withdraw in good order. After dispersing an American detachment at Paoli on September 20, Cornwallis occupied Philadelphia on September 26, with the main force of 9,000 under Howe based just to the north at Germantown . Washington attacked them on October 4, but was repulsed. To prevent Howe's forces in Philadelphia being resupplied by sea,
3429-506: The Battle of Sullivan's Island on June 28, 1776, but it failed. A shortage of gunpowder led Congress to authorize a naval expedition against the Bahamas to secure ordnance stored there. On March 3, 1776, an American squadron under the command of Esek Hopkins landed at the east end of Nassau and encountered minimal resistance at Fort Montagu . Hopkins' troops then marched on Fort Nassau . Hopkins had promised governor Montfort Browne and

The increase in tension led to a scramble for control of militia stores, which each assembly was legally obliged to maintain for defense. On April 19, a British attempt to secure the Concord arsenal culminated in the Battles of Lexington and Concord , which began the Revolutionary War. After
3683-817: The Burning of Norfolk on January 1, 1776. The siege of Savage's Old Fields began on November 19 in South Carolina between Loyalist and Patriot militias, and the Loyalists were subsequently driven out of the colony in the Snow Campaign . Loyalists were recruited in North Carolina to reassert British rule in the South, but they were decisively defeated in the Battle of Moore's Creek Bridge . A British expedition sent to reconquer South Carolina launched an attack on Charleston in
3810-612: The Continental Association ; based on a draft prepared by the First Virginia Convention in August, the association instituted economic sanctions and a full boycott of goods against Britain. While denying its authority over internal American affairs, a faction led by James Duane and future Loyalist Joseph Galloway insisted Congress recognize Parliament's right to regulate colonial trade. Expecting concessions by

Aware of Native American leanings toward the British and fearing an Anglo-Indian attack from Canada, Congress authorized a second invasion in April 1775. After the defeat at the Battle of Quebec on December 31, the Americans maintained a loose blockade of the city until they retreated on May 6, 1776. A second defeat at Trois-Rivières on June 8 ended operations in Quebec. British pursuit

Its watershed drains an area of 13,539 square miles (35,070 km ) and provides drinking water for 17 million people, including half of New York City via the Delaware Aqueduct . The Delaware River has two branches that rise in the Catskill Mountains of New York:
4445-547: The Otter Creek tributary , leading to a water advisory in Philadelphia . With the failure of the dam project to come to fruition, the lack of flood control on the river left it vulnerable, and it has experienced a number of serious flooding events as the result of snow melt or rain run-off from heavy rainstorms. Record flooding occurred in August 1955, in the aftermath of the passing of the remnants of two separate hurricanes over
4572-406: The Port of Wilmington , the Port of Chester , the Port of Paulsboro , the Port of Philadelphia and the Port of Camden . Combined they create one of the largest shipping areas of the United States. In 2015, the ports of Philadelphia, Camden, and Wilmington handled 100 million tons of cargo from 2,243 ship arrivals, and supported 135,000 direct or indirect jobs. The biggest category of imports

The conflict was fought in North America , the Caribbean , and the Atlantic Ocean . The war ended with the Treaty of Paris (1783) , which resulted in Great Britain ultimately recognizing
4826-700: The Second Continental Congress appointed the Committee of Five : Thomas Jefferson , John Adams , Benjamin Franklin , Roger Sherman , and Robert Livingston . The declaration was written almost exclusively by Jefferson. Identifying inhabitants of the Thirteen Colonies as "one people", the declaration simultaneously dissolved political links with Britain, while including a long list of alleged violations of "English rights" committed by George III . This
4953-732: The Sugar Act and Stamp Act , which imposed additional taxes on the colonies to pay for defending the western frontier. In July 1765, the Whigs formed the First Rockingham ministry , which repealed the Stamp Act and reduced tax on foreign molasses to help the New England economy, but re-asserted Parliamentary authority in the Declaratory Act . However, this did little to end the discontent; in 1768,
5080-506: The Treaty of Aranjuez , though Spain did not formally ally with the Americans. Howe's replacement Henry Clinton intended to take the war against the Americans into the Southern Colonies . Despite some initial success, British general Cornwallis was besieged by a Franco-American force in Yorktown in September and October 1781. Cornwallis was forced to surrender in October. The British wars with France and Spain continued for another two years, but fighting largely ceased in North America. In

5334-520: The colonial legislatures agreed on the boundaries but disagreed on where to set them. Many settlers resented the restrictions entirely, and enforcement required permanent garrisons along the frontier, which led to increasingly bitter disputes over who should pay for them. Although directly administered by the Crown , acting through a local governor, the colonies were largely governed by native-born property owners. While external affairs were managed by London, colonial militia were funded locally but with
5461-445: The 26th, the American Patriots surprised and overwhelmed Rall and his troops, who lost over 20 killed including Rall, while 900 prisoners, German cannons and supplies were captured. The Battle of Trenton restored the American army's morale, reinvigorated the Patriot cause, and dispelled their fear of what they regarded as Hessian "mercenaries". A British attempt to retake Trenton was repulsed at Assunpink Creek on January 2; during
5588-402: The American cause. The reduced Continental Army had dwindled to fewer than 5,000 men and was reduced further when enlistments expired at the end of the year. Popular support wavered, and morale declined. On December 20, 1776, the Continental Congress abandoned the revolutionary capital of Philadelphia and moved to Baltimore , where it remained until February 27, 1777. Loyalist activity surged in
5715-526: The Americans at the Battle of Harlem Heights the following day. On October 18, Howe failed to encircle the Americans at the Battle of Pell's Point , and the Americans withdrew. Howe declined to close with Washington's army on October 28 at the Battle of White Plains , and instead attacked a hill that was of no strategic value. Washington's retreat isolated his remaining forces and the British captured Fort Washington on November 16. The British victory there amounted to Washington's most disastrous defeat with
5842-447: The British Parliament imposed the Intolerable Acts in mid-1774. A British attempt to disarm the Americans and the resulting Battles of Lexington and Concord in April 1775 ignited the war. In June, the Second Continental Congress formalized Patriot militias into the Continental Army and appointed Washington its commander-in-chief. The British Parliament declared the colonies to be in a state of rebellion in August 1775. The stakes of
5969-407: The Canadians. In Virginia, Dunmore's Proclamation on November 7, 1775, promised freedom to any slaves who fled their Patriot masters and agreed to fight for the Crown. British forces were defeated at Great Bridge on December 9 and took refuge on British ships anchored near Norfolk. When the Third Virginia Convention refused to disband its militia or accept martial law, Lord Dunmore ordered
6096-461: The Clean Water Act explains how conditions of the river should be stable enough for human fishing and swimming. Even though the river has had success with the cleanup of pollution, the Delaware River still does not meet that standard of swimmable or fishable conditions in the Philadelphia/Chester region. In March 2023, a pipe rupture at a Trinseo chemical plant in Bristol, Pennsylvania , released over 8,000 gallons of latex finishing material into
6223-584: The Colonial Secretary Lord Germain , proposing a limited offensive against Philadelphia, while a second force moved down the Hudson from Canada. Burgoyne supplied several alternatives, all of which gave him responsibility for the offensive, with Howe remaining on the defensive. The option selected required him to lead the main force south from Montreal down the Hudson Valley, while a detachment under Barry St. Leger moved east from Lake Ontario. The two would meet at Albany , leaving Howe to decide whether to join them. Reasonable in principle, this did not account for
6350-541: The Culper Spy Ring substantially increased the effective allocation and deployment of Continental regiments in the field. Throughout the war, Washington spent more than 10 percent of his total military funds on military intelligence . Washington split the Continental Army into positions on Manhattan and across the East River in western Long Island. On August 27 at the Battle of Long Island , Howe outflanked Washington and forced him back to Brooklyn Heights , but he did not attempt to encircle Washington's forces. Through
6477-428: The Delaware River as the River of the Year for 2020, citing 75 years of progress in reducing pollution and restoring wildlife. In 1984, the U.S. Department of the Treasury authorized the creation of a wine region or " American Viticultural Area " called the Central Delaware Valley AVA located in southeastern Pennsylvania and New Jersey .

In Pennsylvania, it consists of the territory along the Delaware River in Bucks County ; in New Jersey, the AVA spans along the river in Hunterdon County and Mercer County from Titusville , New Jersey, just north of Trenton, northward to Musconetcong Mountain . As of 2013, there are no New Jersey wineries in the Central Delaware Valley AVA. In
6731-437: The Delaware River's tributaries. As a result, in 1928 the city decided to draw water from the Delaware River, putting them in direct conflict with villages and towns across the river in Pennsylvania which were already using the Delaware for their water supply. The two sides eventually took their case to the U.S. Supreme Court , and in 1931, New York City was allowed to draw 440 million US gallons (1,700,000 m ) of water
6858-415: The Delaware River. This settlement marked one of the earliest European establishments in the region, with Fort Christina (located near modern-day Wilmington, Delaware) becoming a key trading post and symbol of Swedish colonial ambition. The Swedes engaged in peaceful land negotiations with the local Lenape people and developed a thriving colony. New Sweden became a center for trade and cultural exchange between

Over the winter, poor conditions, supply problems and low morale resulted in 2,000 deaths, with another 3,000 unfit for duty due to lack of shoes. However, Baron Friedrich Wilhelm von Steuben took the opportunity to introduce Prussian Army drill and infantry tactics to "model companies" in each Continental Army regiment, who then instructed their home units. Despite Valley Forge being only twenty miles away, Howe made no effort to attack their camp, an action some critics argue could have ended
7620-448: The Lenape". The Delaware River played a key factor in the economic and social development of the Mid-Atlantic region. In the seventeenth century it provided the conduit for colonial settlement by the Dutch ( New Netherland ) and the Swedish ( New Sweden ). Beginning in 1664, the region became an English possession as settlement by Quakers established the colonies of Pennsylvania (including present-day Delaware ) and West Jersey . In

This slowed Burgoyne's progress and forced him to send out large foraging expeditions; on one of these, more than 700 British troops were captured at the Battle of Bennington on August 16. St Leger moved east and besieged Fort Stanwix ; despite defeating an American relief force at the Battle of Oriskany on August 6, he was abandoned by his Indian allies and withdrew to Quebec on August 22. Now isolated and outnumbered by Gates, Burgoyne continued onto Albany rather than retreating to Fort Ticonderoga, reaching Saratoga on September 13. He asked Clinton for support while constructing defenses around
