Battle of Yorktown

The Battle of Yorktown, in 1781, was the last major battle in the American Revolution. British general Cornwallis was against French general Marquis de Lafayette and General George Washington. French admiral DeGrasse was commander of the French naval fleet and defeated the British navy, thus prohibiting them from entering Chesapeake Bay and giving aid and resources to Cornwallis. Cornwallis was surrounded by Washington's troops  who came from the North and Lafayette's from the South. This was called the 'pincer' strategy. Cornwallis couldn't go anywhere by land or by sea. Cornwallis surrended on October 17, his troops vastly outnumbered. By winning this battle, America won the war
