By July 31 Gregory's men, with Rutherford and his brigade, were with General Caswell at The Cheraws, just across the South Carolina border. For several weeks there was much suffering among the men on account of the lack of food, for though corn was plentiful, the rivers were so high that the mills could not grind the meal. Lord Rawdon's army was stationed near Camden, South Carolina, and Gates, who had joined Caswell on August 17, having learned that the British general was daily expecting a supply of food and stores for his men, determined to intercept the convoy and capture the supplies for his own army. In the meantime Cornwallis, unknown to Gates, had joined Lord Rawdon. Gates, ignorant of this reinforcement of Cornwallis' troops, marched leisurely towards Camden to capture the coveted stores. The result of the battle that followed is known only too well. The American militia, panic-stricken at the furious onslaught of the enemy, threw down their arms and fled. General Gates, after a vain attempt to rally his troops, lost courage, and abandoning his forces and his stores, brought everlasting disgrace upon his name by fleeing in hot haste from the field. But the cowardly conduct of Gates and several of the other officers of the American army, as well as many of the militia, in this disastrous battle, was offset by the heroism and courage of others; and among those who won undying fame on that fatal field, none is more worthy of praise than General Gregory. Roger Lamb, a British officer, writing an account of the battle, and speaking of the disgraceful conduct of those officers and men whose flight from the field brought shame upon the American army, gives this account of Isaac Gregory's heroic struggle to withstand the enemy at this bloody field: "In justice to North Carolina, it should be remarked that General Gregory's brigade acquitted themselves well. They formed on the left of the Continentals, and kept the field while they had a cartridge left. Gregory himself was twice wounded by bayonets in bringing off his men, and many in his brigade had only bayonet wounds." As to fight hand to hand with bayonets requires far more courage than to stand at a distance and fire a musket, this account of Gregory and his troops proves the bravery with which they fought during those terrible hours. General Gregory's horse was shot from under him while the battle was raging; and seeing him fall, so sure was the enemy of his death that Cornwallis in his official report of the battle, gave in his name in the list of the American officers killed on the field.
