In this Grade 8 lesson from IMPACT California Social Studies Chapter 4, students examine the events leading to the American victory at Yorktown, including Washington's secret strategy, the Franco-American alliance with Rochambeau, and the siege tactics that trapped Cornwallis. Students analyze how Lafayette pinned British forces on the Yorktown peninsula while the French fleet blocked Chesapeake Bay, cutting off British supply and escape routes. The lesson builds understanding of how military strategy, alliances, and geography combined to end the Revolutionary War.
Section 1
Leaders Shift Strategy to Trap the British
General George Washington and French commander Comte de Rochambeau initially planned to attack the main British army in New York City. This was the primary British stronghold in North America.
However, they saw a new opportunity when British General Cornwallis moved his army to Yorktown, Virginia. Washington and Rochambeau realized they could trap the British on the coast if they acted quickly and secretly.
Section 2
The Final Battle: Victory at Yorktown (1781)
In 1781, British General Lord Cornwallis positioned his army at Yorktown, Virginia. He expected the powerful British navy to supply and support his troops from the sea, believing his army was safe on the coast.
General Washington and his French allies saw a perfect opportunity. They marched their armies south to surround Yorktown by land, while the French navy sailed in to block the coast. The British fleet was defeated, leaving Cornwallis completely trapped.
Section 3
Securing Independence: The Treaty of Paris (1783)
After the victory at Yorktown, Britain was ready to make peace. The British offered a generous deal, hoping to weaken the alliance between the United States and its powerful allies, France and Spain.
American negotiators, however, dealt directly with Britain. They used key military victories on the western frontier to strengthen their claim to more territory.
Section 4
Washington Prevents a Military Revolt
Even after the victory at Yorktown, the new United States faced internal dangers. The Continental Army had not been paid, and many officers grew angry with the weak national government under the Articles of Confederation.
In 1783, a group of officers considered using the army to force Congress to pay them. This dangerous plot became known as the Newburgh Conspiracy. It threatened to destroy the new republic before it could truly begin.
