The siege of Fort Sackville, also known as the siege of Fort Vincennes or the Battle of Vincennes, was an American Revolutionary War frontier battle fought in present-day Vincennes, Indiana. In February 1779, an American militia led by Lieutenant Colonel George Rogers Clark defeated the British garrison of Fort Sackville commanded by Lieutenant Governor Henry Hamilton. Clark surprised the fort after a gruelling march from Kaskaskia, and following the execution of four Odawa captives, forced Hamilton's surrender.
The American Revolutionary War (1775–1783) grew from colonial resistance to British taxation without parliamentary representation — a dispute that radicalized through the Stamp Act (1765), the Townshend Acts (1767), and the Boston Massacre (1770). Fighting began at Lexington and Concord in April 1775; the Continental Congress declared independence on July 4, 1776. The Continental Army under George Washington faced severe shortages of supplies and troops, enduring the brutal winter at Valley Forge (1777–1778) before French alliance and French financing turned the military balance. Major engagements included Bunker Hill (1775), Trenton (1776), Saratoga (1777) — which secured French intervention — and Yorktown (1781), where British General Cornwallis surrendered to Washington. An estimated 25,000 American soldiers died in service, from combat, disease, and captivity. The Treaty of Paris (1783) recognized American independence and ceded British territory east of the Mississippi, though it left unresolved questions about Indigenous land rights and the status of Loyalists.
