General George Washington, to the President of Congress:
17 February 1781.
General [Daniel] Morgan's signal victory over Colonel [Banastre] Tarleton [at Cowpens] with the flower of the British Army reflects the highest honor upon our arms, and I hope at least be attended with this advantage, that it will check the offensive operations of the enemy until General [Nathanael] Greene shall have collected a much more respectable force than he had under his command by the last accounts from him. I am apprehensive that the Southern States will look upon this victory as much more decisive in its consequences than it really is, and will relax in their exertions. It is to be wished that the gentlemen of Congress who have interests in those States would remove such ideas, if any such should be found to exist, and rather stimulate them to redouble their efforts to crush an enemy, pretty severely shaken by the two successful strokes upon [Patrick] Ferguson [at Kings Mountain] and Tarleton.
