The full effect of the French alliance was not felt until 1781, when Cornwallis went into Virginia and settled at Yorktown. Accompanied by French troops Washington swept rapidly southward and penned the British to the shore while a powerful French fleet shut off their escape by sea. It was this movement, which certainly could not have been executed without French aid, that put an end to all chance of restoring British dominion in America. It was the surrender of Cornwallis at Yorktown that caused Lord North to pace the floor and cry out: "It is all over! It is all over!" What might have been done without the French alliance lies hidden from mankind. What was accomplished with the help of French soldiers, sailors, officers, money, and supplies, is known to all the earth. "All the world agree," exultantly wrote Franklin from Paris to General Washington, "that no expedition was ever better planned or better executed. It brightens the glory that must accompany your name to the latest posterity." Diplomacy as well as martial valor had its reward. PEACE AT LAST =British Opposition to the War.=--In measuring the forces that led to the final discomfiture of King George and Lord North, it is necessary to remember that from the beginning to the end the British ministry at home faced a powerful, informed, and relentless opposition. There were vigorous protests, first against the obnoxious acts which precipitated the unhappy quarrel, then against the way in which the war was waged, and finally against the futile struggle to retain a hold upon the American dominions. Among the members of Parliament who thundered against the government were the first statesmen and orators of the land. William Pitt, Earl of Chatham, though he deplored the idea of American independence, denounced the government as the aggressor and rejoiced in American resistance. Edmund Burke leveled his heavy batteries against every measure of coercion and at last strove for a peace which, while giving independence to America, would work for reconciliation rather than estrangement. Charles James Fox gave the colonies his generous sympathy and warmly championed their rights. Outside of the circle of statesmen there were stout friends of the American cause like David Hume, the philosopher and historian, and Catherine Macaulay, an author of wide fame and a republican bold enough to encourage Washington in seeing it through.
