Title: Siege of Yorktown
Content:  The siege of Yorktown, also known as the Battle of Yorktown, the surrender at Yorktown, or the German battle (from the presence of Germans in all three armies), beginning on September 28, 1781, and ending on October 19, 1781, at Yorktown, Virginia, was a decisive victory by a combined force of the American Continental Army troops led by General George Washington and Gilbert du Motier, Marquis de Lafayette, and French Army troops led by Comte de Rochambeau over a British army commanded by British peer and Lieutenant General Charles Cornwallis. The culmination of the Yorktown Campaign, the siege proved to be the last major land battle of the American Revolutionary 
Title: Yorktown campaign
Content:  The Yorktown or Virginia campaign was a series of military maneuvers and battles during the American Revolutionary War that culminated in the decisive siege of Yorktown in October 1781. The result of the campaign was the surrender of the British Army force of General Charles Earl Cornwallis, an event that led directly to the beginning of serious peace negotiations and the eventual end of the war. The campaign was marked by disagreements, indecision, and miscommunication on the part of British leaders, and by a remarkable set of cooperative decisions, at times in violation of orders, by the French and Americans. The campaign involved land and naval forces of Great Britain and France, and land forces of the United States. British forces were sent to 
Title: Yorktown order of battle
Content:  The Siege of Yorktown was the culminating act of the Yorktown campaign, a series of military operations occupying much of 1781 during the American Revolutionary War. The siege was a decisive Franco-American victory: after the surrender of British Lt. Gen. Charles, Earl Cornwallis on October 17, the government of Lord North fell, and its replacement entered into peace negotiations that resulted in British recognition of American independence with the 1783 Treaty of Paris. The siege involved land forces from the United States, including the Continental Army and state militias, as well as land forces under French and British command. The British forces included a large number of troops from various German principalities of the Holy Roman Empire that were collectively known as 
Title: Siege of Yorktown (1862)
Content:  The Battle of Yorktown or Siege of Yorktown was fought from April 5 to May 4, 1862, as part of the Peninsula Campaign of the American Civil War. Marching from Fort Monroe, Union Maj. Gen. George B. McClellan's Army of the Potomac encountered Maj. Gen. John B. Magruder's small Confederate force at Yorktown behind the Warwick Line. McClellan suspended his march up the Peninsula toward Richmond and settled in for siege operations. On April 5, the IV Corps of Brig. Gen. Erasmus D. Keyes made initial contact with Confederate defensive works at Lee's Mill, an area McClellan expected to move through without resistance. Magruder's ostentatious movement of troops back and forth convinced the Union that his works were strongly held. As the two armies fought an artillery duel, reconnaissance indicated to Keyes the strength and breadth of the Confederate fortifications,

Far fewer Loyalists took up arms than Britain needed; royal efforts to control the countryside in the South failed. When the British army tried to return to New York, its rescue fleet was turned back by the French Navy and its army was captured by combined French-American forces under General George Washington at the Siege of Yorktown in October 1781. That effectively conceded American success. Opinion in Scotland often favoured the American cause, or criticised the poor performance of the British army.

However, Hamilton protested, saying that he was the senior officer. Washington concurred with Hamilton and gave him command of the attack. At 6:30 pm, gunfire announced the diversionary attack on the Fusiliers redoubt. At other places in the line, movements were made as if preparing for an assault on Yorktown itself, which caused the British to panic. With bayonets fixed, the Americans marched towards Redoubt No. 10. Hamilton sent Lieutenant Colonel John Laurens around to the rear of the redoubt to prevent 
Title: Battle of York
Content:  As the American attack on York occurred on the first of New York's three day election period, the battle did not directly benefit the Democratic-Republic Party as Armstrong had originally envisioned. However, early proclamations of victory issued prior to the battle, did contribute to the reelection of Daniel D. Tompkins, the Democratic-Republican candidate for the Governor of New York. According to Pierre Berton, the battle, and occupation of York served as a watershed moment for the settlers of York. Those who fought the Americans became celebrated in the local community, while those who aided the occupation were viewed by the community as traitors. The documentary film Explosion 1812 argues that the battle

By disguising his movements, Washington moved the combined forces South to Virginia without the British commanders in New York realizing it. This resulted in the capture of the main British invasion force in the South at Siege of Yorktown. The Americans and their allies had won the land war in North America and independence was assured. Before the peace treaty went into effect in 1783, the British partly recovered by defeating the French fleet at the Battle of the Saintes.

Johnston brought reinforcements for Magruder. On April 16, Union forces probed a point in the Confederate line at Dam No. 1. The Union failed to exploit the initial success of this attack, however. This lost opportunity held up McClellan for two additional weeks while he tried to convince the U.S. Navy to bypass the Confederates' big guns at Yorktown and Gloucester Point and ascend the York River to West Point and outflank the Warwick Line. McClellan planned a massive bombardment for dawn on May 5, but the Confederate army slipped away during the night of May 3 toward Williamsburg. The battle took place near the site of the 1781 Siege of Yorktown.

These forces were first opposed weakly by Virginia militia, but General George Washington sent first Marquis de Lafayette and then "Mad" Anthony Wayne with Continental Army troops to oppose the raiding and economic havoc the British were wreaking. The combined American forces, however, were insufficient in number to oppose the combined British forces, and it was only after a series of controversially confusing orders by General Sir Henry Clinton, the British commander-in-chief, that Cornwallis moved to Yorktown in July and built a defensive position that was strong against the land forces he then faced, but was vulnerable to naval blockade and
