American Revolution War — Military Campaigns of the War for Independence

The American Revolutionary War was the military conflict that secured American independence from Great Britain. Fought between 1775 and 1783, the war pitted the thirteen American colonies against the most powerful empire in the world. Against all odds, the Continental Army and its French allies defeated the British and established the United States as an independent nation.

The war was not a single conflict but a complex series of campaigns that stretched from Canada to the Caribbean and from the Atlantic coast to the Mississippi River. The American victory was the result of strategic leadership, foreign assistance, British mistakes, and the determination of ordinary Americans to win their freedom.

The Outbreak of War

The war began in Massachusetts on April 19, 1775, when British troops marched from Boston to Concord to seize colonial military supplies. At Lexington, they encountered a militia company, and someone fired — the “shot heard round the world.” The British continued to Concord, where they fought another engagement, then retreated to Boston under constant attack from colonial militiamen.

The Battle of Bunker Hill on June 17, 1775, was the first major battle of the war. American forces fortified Breed’s Hill overlooking Boston, and the British launched two frontal assaults that were repulsed with heavy losses. The third assault succeeded only because the Americans ran out of ammunition. The British suffered over 1,000 casualties, the Americans about 400. The battle demonstrated that American soldiers could fight effectively against British regulars.

The Continental Congress appointed George Washington of Virginia as commander-in-chief of the Continental Army in June 1775. Washington took command of the army besieging Boston and faced the enormous challenge of creating a professional army from a collection of militia units with no training, discipline, or organization.

The Campaign for New York

The British evacuated Boston in March 1776, relocating their forces to New York, which became the main theater of the war. General William Howe assembled the largest British expeditionary force of the eighteenth century — over 30,000 troops, including German mercenaries from Hesse-Cassel.

Washington moved his army to New York to defend the city. The British attacked in August 1776, landing on Long Island and flanking the American positions. The Battle of Long Island was a disaster for the Americans, who were saved from complete destruction only by a skillful night evacuation across the East River.

The British pursued Washington through New York and New Jersey. The American army retreated across the Delaware River into Pennsylvania, reduced to a few thousand men and on the verge of disintegration. But Washington staged a daring counterattack on Christmas night 1776, crossing the Delaware River and surprising the Hessian garrison at Trenton. He followed this with a victory at Princeton in early January 1777.

Saratoga and the French Alliance

The British strategy for 1777 involved a plan to cut the American colonies in two by capturing the Hudson River valley. General John Burgoyne led an army south from Canada, while General Howe was supposed to advance north from New York. But Howe decided to capture Philadelphia instead, leaving Burgoyne to advance alone.

Burgoyne’s army became bogged down in the forests of upstate New York. American forces under General Horatio Gates and Benedict Arnold defeated the British at the Battle of Freeman’s Farm in September 1777 and the Battle of Bemis Heights in October 1777. Burgoyne surrendered his entire army at Saratoga on October 17, 1777.

The victory at Saratoga was the turning point of the war. The French, who had been secretly supplying the Americans, decided to enter the war openly. The Treaty of Alliance signed in February 1778 brought France into the war on the American side. French military and naval support would prove essential to American victory.

The War in the South

The British shifted their strategy after Saratoga, focusing on the southern colonies, where they believed loyalist sentiment was strong. British forces captured Savannah in 1778 and Charleston in 1780, the worst American defeat of the war.

The British occupation of the South provoked a brutal guerrilla war. American partisan leaders like Francis Marion, the “Swamp Fox,” harassed British supply lines and loyalist forces. The British commander Lord Cornwallis found that controlling the countryside was far more difficult than capturing cities.

General Washington appointed Nathanael Greene to command American forces in the South. Greene, a brilliant strategist, used a strategy of avoiding decisive battles while wearing down the British army through attrition. The Battle of Cowpens in January 1781 and the Battle of Guilford Courthouse in March 1781 demonstrated the effectiveness of Greene’s strategy.

Yorktown and Victory

Cornwallis moved his army to Yorktown, Virginia, on the Chesapeake Bay, expecting to be supplied by the British navy. Washington, seeing an opportunity, moved his army south from New York while the French navy sailed from the West Indies to cut off British sea access.

The French fleet under Admiral de Grasse defeated the British fleet at the Battle of the Chesapeake on September 5, 1781, blocking British access to Yorktown. Washington and the French general Rochambeau besieged Yorktown with 17,000 troops. After three weeks of bombardment, Cornwallis surrendered on October 19, 1781.

The victory at Yorktown effectively ended the war. The British Parliament voted to end offensive operations in America, and peace negotiations began. The Treaty of Paris, signed in 1783, recognized American independence and established the boundaries of the new nation.

The Nature of the War

The American Revolutionary War was a conflict of unusual brutality and complexity. It was a civil war as well as a war for independence, dividing families and communities between Patriots and Loyalists. Perhaps 20 percent of Americans remained loyal to the Crown, and tens of thousands fought on the British side.

The war was also a global conflict, with fighting in the Caribbean, Europe, and India as well as America. France, Spain, and the Netherlands all entered the war against Britain, turning the American conflict into a global war. The naval war was as important as the land war, with control of the sea deciding the fate of campaigns.

The American victory was remarkable. The Continental Army, poorly supplied and often unpaid, held together through years of hardship. Washington’s leadership — his determination, his integrity, and his ability to learn from mistakes — was essential to American success. The French alliance provided the military and naval support that made victory possible.

The American Revolution War is connected to other military conflicts of the period. The War of 1812 military campaigns that followed built on the military traditions established during the Revolution. The Napoleonic Wars in Europe were shaped by some of the same military innovations.
