9) The French navy was responsible for British defeat in America itself
French intervention made the British position in America much more vulnerable. Until 1778, the British army had been able to rely on the dominance of the Royal Navy. British troops could be conveyed anywhere along the Atlantic coast of the colonies, and British generals had no need to fear for their extended Atlantic supply line.
But once the French joined the war, their navy posed an immediate threat. If French ships could co-operate with American troops on land, isolated British outposts could be captured.
At first, the French and Americans failed to co-ordinate their operations, but at Yorktown, Virginia, they succeeded to dramatic effect in autumn 1781. General Cornwallis’s British army was trapped by American and French troops and cut off from relief by the French navy. Cornwallis’s surrender effectively ended the war in America.
