After
fighting broke out in April 1775, Washington appeared at the
Second Continental Congress in military uniform, signaling that he was prepared for war. Washington had the prestige, the military experience, the charisma and military bearing, the reputation of being a strong patriot, and he was supported by the South, especially Virginia. Although he did not explicitly seek the office of commander and even claimed that he was not equal to it, there was no serious competition. Congress created the Continental Army on
June 14; the next day, on the nomination of John Adams of
Massachusetts, it selected Washington as Commander-in-chief. Washington assumed command of the American forces in Massachusetts in July 1775, during the ongoing
siege of Boston. Realizing his army's desperate shortage of gunpowder, Washington asked for new sources. British arsenals were raided (including some in the
Caribbean) and some manufacturing was attempted; a barely adequate supply (about 2.5 million pounds) was obtained by the end of 1776, mostly from France. Washington reorganized the army during the long standoff, and forced the British to withdraw by putting artillery on
Dorchester Heights overlooking the city. The British
evacuated Boston and Washington moved his army to
New York City.
Although negative toward the patriots in the Continental Congress, British newspapers routinely praised Washington's personal character and qualities as a military commander. Moreover, both sides of the aisle in Parliament found the American general's courage, endurance, and attentiveness to the welfare of his troops worthy of approbation and examples of the virtues they and most other Britons found wanting in their own commanders. Washington's refusal to become involved in politics buttressed his reputation as a man fully committed to the military mission at hand and above the factional fray.
In August 1776, British General
William Howe launched a massive naval and land campaign designed to seize New York and offer a negotiated settlement. The Continental Army under Washington engaged the enemy for the first time as an army of the newly-declared independent United States at the
Battle of Long Island, the largest battle of the entire war. This and several other British victories (despite some American victories at the
Battle of Harlem Heights and elsewhere) sent Washington scrambling out of New York and across
New Jersey, leaving the future of the Continental Army in doubt. On the night of
December 25,
1776, Washington staged a
counterattack, leading the American forces
across the Delaware River to capture nearly 1,000
Hessians in
Trenton, New Jersey.
Washington was defeated at the
Battle of Brandywine on
September 11,
1777. On
September 26, Howe outmaneuvered Washington and marched into Philadelphia unopposed. Washington's army
unsuccessfully attacked the British garrison at
Germantown in early October. Meanwhile Burgoyne, out of reach from help from Howe, was trapped and forced to
surrender his entire army at
Saratoga, New York. As a result of this battle, France entered the war as an open ally of the Americans, turning the Revolution into a major world-wide war. Washington's loss of Philadelphia prompted some members of Congress to discuss removing Washington from command. This
episode failed after Washington's supporters rallied behind him.
Washington's army encamped at
Valley Forge in December 1777, where it stayed for the next six months. Over the winter, 2,500 men (out of 10,000) died from disease and exposure. The next spring, however, the army emerged from Valley Forge in good order, thanks in part to a full-scale training program supervised by
Baron von Steuben, a veteran of the Prussian general staff. The British evacuated Philadelphia in 1778 and returned to New York City. Meanwhile, Washington remained with his army outside New York, and in the summer of 1779, at Washington's direction,
General John Sullivan, in retaliation for Iroquois and Tory attacks against American settlements earlier in the war, carried out a decisive
scorched earth campaign that destroyed at least forty Iroquois villages throughout what is now upstate New York. He delivered the final blow in 1781, after a
French naval victory allowed American and French forces to trap a British army in Virginia. The
surrender at Yorktown on
October 17,
1781 marked the end of fighting. Though known for his successes in the war and of his life that followed, Washington only won three of the nine battles that he fought.
In March 1783, Washington used his influence to disperse a
group of Army officers who had threatened to confront Congress regarding their back pay. The
Treaty of Paris (signed that September) recognized the independence of the United States. Washington disbanded his army and, on
November 2, gave an eloquent farewell address to his soldiers. On
November 25, the
British evacuated New York City, and Washington and the governor took possession. At
Fraunces Tavern on
December 4, Washington formally bade his officers farewell and on
December 23,
1783, he resigned his commission as commander-in-chief, emulating the
Roman general Cincinnatus, an exemplar of the republican ideal of citizen leadership who rejected power. During this period, the United States was governed under the Articles of Confederation without a President; governmental organization was different from the present form.
Washington's retirement to Mount Vernon was short-lived. He was persuaded to attend the Philadelphia Convention in
Philadelphia in the summer of 1787, and he was unanimously elected president of the Convention. He participated little in the debates involved (though he did vote for or against the various articles), but his high prestige maintained collegiality and kept the delegates at their labors. The delegates designed the presidency with Washington in mind, and allowed him to define the office once elected. After the Convention, his support convinced many, including the Virginia legislature, to vote for ratification; the new
Constitution was ratified by all 13 states.
