what fort supplied the cannon used to relieve the siege of boston
Siege of Boston In November 1775, Washington sent the 25-year-old bookseller-turned-soldier Henry Knox to bring to Boston the heavy artillery that had been captured at Fort Ticonderoga. In a technically complex and demanding operation, Knox brought many cannons to the Boston area by January 1776. In March 1776, these artillery fortified Dorchester Heights (which overlooked Boston and its harbor), thereby threatening the British supply lifeline. The British commander William Howe saw the British position as indefensible and withdrew the British forces in Boston to the British stronghold at Halifax, Nova Scotia, on March 17 (celebrated today as Evacuation Day).

American Revolutionary War On April 18, 1775, 700 troops were sent to confiscate militia ordnance stored at Concord.[94][95] Fighting broke out, forcing the regulars to conduct a fighting withdrawal to Boston. Overnight, the local militia converged on and laid siege to Boston.[96] On March 25, 4,500 British reinforcements arrived with three senior generals; William Howe, John Burgoyne and Henry Clinton.[97] On June 17, the British seized the Charlestown peninsular after a costly frontal assault,[98][99] leading Howe to replace Gage.[100] Many senior officers were dismayed at the attack which had gained them little,[101] while Gage wrote to London stressing the need for a large army to suppress the revolt.[102] On July 3, George Washington took command of the Continental Army besieging Boston. Howe made no effort to attack, much to Washington's surprise.[103] After a plan to assault the city was rejected,[104] in early March 1776, the Americans fortified Dorchester Heights with heavy artillery captured from a raid on Fort Ticonderoga.[105] On March 17, the British were permitted to withdraw unmolested, sailing to Halifax, Nova Scotia. Washington then moved his army to New York.[106]
American Revolution The Continental Army forced the redcoats out of Boston in March 1776, but that summer the British captured and held New York City and its strategic harbor for the duration of the war. The Royal Navy blockaded ports and captured other cities for brief periods, but they failed to defeat Washington's forces. The Patriots unsuccessfully attempted to invade Canada during the winter of 1775–76, but successfully captured a British army at the Battle of Saratoga in October 1777. France now entered the war as an ally of the United States with a large army and navy that threatened Britain itself. The war turned to the American South where the British under the leadership of Charles Cornwallis captured an army at Charleston, South Carolina in early 1780 but failed to enlist enough volunteers from Loyalist civilians to take effective control of the territory while fighting partisans. A combined American–French force captured a second British army at Yorktown in the fall of 1781, effectively ending the war in North America. The Treaty of Paris, signed September 3, 1783, formally ended the conflict, confirming the new nation's complete separation from the British Empire. The United States took possession of nearly all the territory east of the Mississippi River and south of the Great Lakes, with the British retaining control of Canada and Spain taking Florida.
