In 1781 he marched with his "Legion" to join Greene in the Carolinas, carrying with him the high esteem of Washington, who had witnessed his skilful and daring operations in the Jerseys.

His career in the arduous campaigns of the South against Cornwallis, and the efficient commander of his cavalry arm.

Colonel Tarleton, may be best understood from General Greene's dispatches, and from his own memoirs of the operations of the army, which are written with as much modesty as ability.

From these it is apparent that the small body of the "Legion" cavalry, under its active and daring commander, was the "eye and ear" of Greene's army, whose movements it accompanied everywhere, preceding its advances and covering its retreats.

Few pages of military history are more stirring than those in Lee's "Memoirs" describing Greene's retrograde movement to the Dan; and this alone, if the hard work at the Eutaws and elsewhere were left out, would place Lee's fame as a cavalry officer upon a lasting basis.
