In July, 1780, despairing of receiving the promised aid from the State of Virginia, and anxious to join the army under Gates, then in South Carolina, Colonel White procured on his own personal credit, the funds necessary to remount and support for a short time, two regiments; with which he marched to join Gates—fortunately too late to share in the defeat at Camden (and yet, that same rout might have been a victory, had a sufficient force of cavalry been among Gates’ men). In 1781, White was ordered to Virginia to coöperate with Lafayette’s force against Cornwallis, and several times skirmished with Tarleton. In the winter of 1781–2, he was again in the Carolinas, opposed to him; and in the operations of Wayne at Savannah, May 21, 1782, Colonel White by his bold and adroit conduct, contributed largely to the success which followed. After the evacuation of the city by the enemy, he returned to South Carolina, and entered Charleston, where his noted generosity was exemplified by his becoming security for the debts of the officers and men of his command, who were in want of almost all the necessaries of life. They agreed to repay him in tobacco—then the only currency of any stable value—which was to be delivered to him at Charleston on a fixed date. Owing partly to the failure of the crop that year, and partly to the inability of his beneficiaries to carry out their part of the agreement, he had to part with a large part of his Northern property, at a ruinous sacrifice. In the spring of 1783, he was married to Margaret Ellis, a young girl of only fifteen, but who is described as of remarkable accomplishments, as well as of wealth and beauty. After the conclusion of hostilities, he returned to the North and settled in New York City to spend the remainder of his life, as he hoped, in tranquil enjoyment of well-earned repose, and regain his former affluence; but was unhappily persuaded by his old army friends to join them in a speculation which, as the only responsible member of the organization, nearly ruined him as a result.
