ANSWER
The victory of Admiral Comte de Grasse's French Fleet upon the British Fleet under Admiral Thomas Graves cut off Cornwallis Army from being supported by reinforcements and supplies.
Furthermore De Grasse had been able to land reinforcements and a siege train to strengthen the siege operation of the British position at Yorktown.
After the Battle of Chesapeake Bay, when the French Fleet defeated the British, Cornwallis was cut off from his maritime communication line and couldn't receive any reinforcement and supply. Thus allowed the French-American army led by Washington and Rochambeau to start a regular siege of the British position of Yorktown on October 6 ,1781, by building the first parallel of approach.
The siege was further tightened by a second parallel on October 10th, and by the conquest of two pivotal British redoubts near the River York, east of the town on October 14th
A British sortie to prevent the closer emplacement of the Allied siege artillery was repulsed on October 16th and the town was subjected to a heavy and destructive cannonade, which forced Cornwallis to surrender on October 19,1781.
The victory at Yorktown was made possible by the French Marines and Navy. Without their assistance, the British would have escaped to fight somewhere else.
For once the British did not have command of the sea. The French fleet managed to blockade the Chesapeake to prevent the British from either supplying Yorktown or evacuating them.
The French navy
it was important because it gave freedom and independence to the americans. Obviously, but there is more to it than that. It was the beginning of something crucial to what everything is now. Because of the events leading up to the battle at Yorktown, we managed to defeat our opposser and get our hands on what we've wanted this whole time; freedom and independence. But not only to the American's did the spoils go. Many people openly benefited from this exchange, such as the French. Because they stuck with the Americans during the hardships of the battle at Trenton, and generously gave them the idea to cut down bridges and tree's in hopes to "corner" them, they got themselves respectable allies and made the turning point in the Revolutionary war possible. During the Battle @ Yorktown, the patriots traveled over 200 miles in fifteen day's. They met General Cornwallis and the British troops in Virginia. Three sets of troops were used to close in on the redcoats. The British were confused, low on supplies, and many were sick. The Americans trapped Cornwallis on the peninsula, which meant they were cornered on three sides by water and another by angry Patriots, with no where to go. This also was mainly due to the French fleet that arrived six hours before the British fleet, blocking their only escape route at the time. Cornwallis surrender's, and, tada, the war is over. The U.S.A gained the Treaty of Paris, land from the Atlantic Ocean to the Mississippi River and from Canada to Florida. A part from this, the Redcoats were forced to leave.

Ultimately, American won through attrition. America made the war so costly for Great Britain for so long that Cornwallis's surrender at Yorktown persuaded Parliament that it was better to lose the colonies than to continue in protracted and expensive war with no end in sight.
His victory at San Jacinto.
British laws that affected the colonies were made by the King and the British Parliament. The colonists had no voice in the laws.
well they trapped them and then surrounded them and the british finally surrendered
After the Patriot victory at Yorktown (Virginia) in 1781, the British decided to bring the Revolutionary War to an end. While several small skirmishes between Americans and British, as well as various debates among British leaders, would take place before ratification of a formal treaty, the fundamental decision to make terms with the "rebels" in America was made by the British after their crushing defeat at Yorktown.

Two events in particular led to the Patriot victory over the British at Yorktown. The first was the assembly of a large and well-led army, a mixture of American and French forces that outnumbered and outmaneuvered the British force led by Lord Cornwallis. The second was an important naval victory by a French fleet over a British fleet that resulted in the isolation of the British land-force and the severing of its supply line.
he was a british general who lost the battle of Yorktown he also lived in a house made of cornbread
Because the British fortifications bordered the York River, it made it easy for the American and French forces to surround Cornwallis' army and secure victory.
Lord Cornwallis was one of the top British generals in the Revolutionary War. He was successful in several battles, but is best remembered for his surrender to colonial forces at Yorktown in 1781, effectively ending the war.
Yorktown was on the water on one side, so the British army could not escape the large American/French army that was bombarding them. Rather than let his soldiers die, their commander, Cornwallis, elect to surrender. Cornwallis had pleaded for help from General Clinton's ships up in New York, but Clinton would not hurry for anybody, and so the ships made it to Yorktown a couple of days after Cornwallis had surrendered.
In my opinion two battles had the greatest impact on the outcome of Revolutionary War: 1 - Saratoga, because the victory of the Continental Army and the capture of a British Army convbinced France to intervene in the conflict on the American side. 2 - Yorktown, because the victory of the American-French allied army and the surrendering of Cornwallis' army made the British to give up further military actions against the 13 Colonies.
In June 1781, British general Lord Cornwallis instead attacking the inferior American Army of 4,500 men, led by the Marquis of Lafayette, the Baron von Steuben and gen. John Wayne, with his overwhelming force of 7,500 men, chose to retreat eastward to the coast to maintain sea communication with Sir Henry Clinton in New York City. As the British Fleet had been driven off the Bay of Chesapeake by De Grasse's French Fleet, he could not relieved and evacuated and remained trapped in Yorktown between Washington's and Rochambeau's Army coming from the north and Lafayette's Army of Virginia.
General George Cornwallis made the strategic battle in the battle of Yorktown.
