The Siege of Yorktown, Battle of Yorktown, or Surrender of Yorktown , the latter taking place on October 19, 1781, was a decisive victory by a combined assault of American forces led by General George Washington and French forces led by the Comte de Rochambeau over a British Army commanded by Lieutenant General Lord Cornwallis. The culmination of the Yorktown campaign, it proved to be the last major land battle of the American Revolutionary War in North America, as the surrender of Cornwallis' army prompted the British government eventually to negotiate an end to the conflict.

In 1780, 5,500 French soldiers landed in Rhode Island to assist their American allies in operations against British-controlled New York City. Following the arrival of dispatches from France that included the possibility of support from the French West Indies fleet of the Comte de Grasse, Washington and Rochambeau decided to ask de Grasse for assistance either in besieging New York, or in military operations against a British army operating in Virginia. On the advice of Rochambeau, de Grasse informed them of his intent to sail to the Chesapeake Bay, where Cornwallis had taken command of the army. Cornwallis, at first given confusing orders by his superior officer, Henry Clinton, was eventually ordered to make a defensible deep-water port, which he began to do at Yorktown, Virginia. Cornwallis's movements in Virginia were shadowed by a Continental Army force led by the Marquis de Lafayette.

Albert Arnold "Al" Gore, Jr. (born March 31, 1948) served as the 45th Vice President of the United States (1993–2001), under President Bill Clinton. He was the Democratic Party's nominee for President and won the popular vote in the 2000 U.S. presidential election.

Gore is currently an author and environmental activist. He has founded a number of non-profit organizations, including the Alliance for Climate Protection, and has received a Nobel Peace Prize for his work in climate change activism.

Gore was previously an elected official for 24 years, representing Tennessee in the U.S. House of Representatives (1977–85), and later in the U.S. Senate (1985–93), and finally becoming Vice President in 1993. In the 2000 presidential election, Gore won the popular vote by a margin of more than 500,000 votes. However, he ultimately lost the Electoral College to Republican George W. Bush when the U.S. Supreme Court settled the legal controversy over the Florida vote recount by ruling 5-4 in favor of Bush. It was the only time in history that the Supreme Court has determined the outcome of a presidential election.
