Meanwhile, in England the king was imposing his relentless will upon a
ministry tired of the war, and upon the English people. It was the climax
of George the Third's effort to escape from the principle of Parliamentary
responsibility. "This country," he said, "will never regain a proper tone
unless ministers, as in the reign of King William, will not mind now and
then being in a minority." In April, 1779, Spain allied herself with
France, and the combined fleets of those two powers obtained the mastery
of the seas. Paul Jones, with a little fleet under an American commission,
captured two British men-of-war, almost in sight of the English coast.

[Sidenote: Southern campaign.]

A new plan was formed for an American campaign in 1779. Forces were
directed against Georgia and South Carolina,--States in which there were
many loyalists. Savannah was taken, Charleston was assailed, and the
expedition under Cornwallis penetrated far into North Carolina. Yet at the
end of 1780 the British held, besides New York, only the provinces of
South Carolina and Georgia. In September, 1780, Benedict Arnold all but
delivered to the hands of the enemy the important fortress of West Point.
He was weary of the struggle, and anxious to secure his own safety.

[Sidenote: Surrender of Yorktown.]

With renewed spirit the Americans in 1781 took the offensive in the
Carolinas under Greene. Cornwallis moved northward to the peninsula of
Yorktown. The moment had come. By a rapid movement of Washington's army
and the effective cooperation of the French fleet, Cornwallis was trapped
at Yorktown; and on Oct. 19, 1781, he surrendered, with eight thousand
men. It was the first decided victory which Washington had himself gained.
