During the Revolution his services were, in more than one critical situation, of great value to the American cause. In the campaign which ended with Burgoyne's defeat, for instance, his riflemen fought like heroes. General Burgoyne, after his surrender, exclaimed to Morgan: "Sir, you command the finest regiment in the world." Indeed, it was regarded at that time as the best regiment in the American army, and this was largely due to Morgan's skill in handling his men. He made them feel as if they were one family. He was always thoughtful for their health and comfort, and he appealed to their pride but never to their fear. He was a very tall and strong man, with handsome features and a remarkable power to endure. His manner was quiet and refined, and his noble bearing indicated a high sense of honor. He was liked by his companions because he was always good-natured and ready for the most daring adventure. General Greene made good use of this true patriot, and not long after taking command of the army he sent Morgan with nine hundred picked men to the westward to threaten the British outposts. General Cornwallis, in command of the British army in the south, ordered Colonel Tarleton to lead a body of soldiers against Morgan. Early in the morning of January 17, 1781, after a hard night march, Tarleton, overconfident of success, attacked Morgan at Cowpens, in the northern part of South Carolina. The Americans stood up bravely against the attack and won a brilliant victory. The British lost almost their entire force, including six hundred prisoners. Cornwallis was bitterly disappointed, for his plan, undertaken in such confidence, had ended in a crushing defeat. However, gathering his forces together, he set out to march rapidly across country in pursuit of Morgan, hoping to overwhelm him and recapture the six hundred British prisoners before he could join Greene's army. But Morgan was too wary to be caught napping, and, suspecting that this would be Cornwallis's game, he retreated rapidly in a northeasterly direction toward that part of the army under Greene. Meantime Greene had heard the glorious news of the American victory at Cowpens, and he too realized that there was great danger of Morgan's falling into the hands of Cornwallis. To prevent this, and at the same time draw Cornwallis far away from his supplies at Wilmington, he decided to go to Morgan's relief. Sending his army by an easier, roundabout route, he himself with a small guard rode swiftly a distance of one hundred and fifty miles across the rough country and joined Morgan on the last day of January. Morgan was cleverly retreating with Cornwallis in hot pursuit. For ten days the race for life continued, with the chances in favor of Cornwallis, for his army was larger, besides being trained and disciplined.
