When Cornwallis, after the surrender of General Gates, moved his whole army toward Waxhaw, Mrs. Jackson and her sons were obliged to seek a safe retreat with a distant relative. Here Andrew did "chores" for his board. "Never," said one who knew him well at this time, "did Andrew come home from the shops without bringing with him some new weapon with which to kill the enemy. Sometimes it was a rude spear, which he would forge while waiting for the blacksmith to finish his job. Sometimes it was a club or a tomahawk. Once he fastened the blade of a scythe to a pole, and, on reaching home, began to cut down the weeds with it that grew about the house, assailing them with extreme fury, and occasionally uttering words like these, 'Oh, if I were a man, how I would sweep down the British with my grass blade!'" A year later, when Mrs. Jackson had returned to Waxhaw, the brothers were both taken prisoners in a skirmish. Being commanded to clean the boots of a British officer, Andrew refused, saying, "Sir, I am a prisoner of war, and claim to be treated as such." The angry Englishman drew his sword, and rushed at the boy, who, attempting to defend himself from the blow, received a deep gash in his left hand, and also on his head, the scars of which he bore through life. Robert, the brother, also refused to clean the boots, and was prostrated by the sword of the brutal officer. Soon after, the boys were taken with other prisoners to Camden, eighty miles distant, a long and agonizing journey for wounded men. They found the prison a wretched place, with no medical supplies; the food scanty, and small-pox raging among the inmates. The poor mother, hearing of their forlorn condition, hastened to the place. Both her boys were ill of the dreaded small-pox, and both suffering from their sword-wounds. She arranged for the exchange of prisoners, and took her sons home; Robert to die in her arms two days later, and Andrew to be saved at last after a perilous illness of several months. Her oldest son, Hugh, had already given his life to his country in the war. Almost broken-hearted with the loss of her two sons, yet intensely patriotic, she hastened to the Charleston prison-ships, to care for the wounded, taking with her provisions and medicine sent by loving wives and daughters. The blessed ministrations proved of short duration. Mrs. Jackson was taken ill of ship-fever, died after a brief illness, and was buried in the open plain near by. The grave is unmarked and unknown. When, years later, her illustrious son had become President, he tried to find the burial-place of the woman he idolized, but it was impossible.
