It is on record that he marched sixty-four miles in twenty-three hours and a hundred and five miles in fifty-four hours.
Such mobility was irresistible.

On the 12th of April, after a ride of thirty miles, Tarleton surprised, in the night, three regiments of American cavalry regulars at a place called Biggin's Bridge, routed them completely and, according to his own account, with the loss of three men wounded, carried off a hundred prisoners, four hundred horses, and also stores and ammunition.

There is no doubt that Tarleton's dragoons behaved with great brutality and it would perhaps have taught a needed lesson if, as was indeed threatened by a British officer, Major Ferguson, a few of them had been shot on the spot for these outrages.
Tarleton's dashing attacks isolated Charleston and there was nothing for Lincoln to do but to surrender.

This he did on the 12th of May.

Burgoyne seemed to have been avenged.
