Hathcock only once removed the white feather from his bush hat while deployed in Vietnam. During a volunteer mission days before the end of his first deployment, he crawled over 1,500 yards of field to shoot a PAVN General. He was not informed of the details of the mission until he accepted it. This effort took four days and three nights, without sleep, of constant inch-by-inch crawling. Hathcock said he was almost stepped on as he lay camouflaged with grass and vegetation in a meadow shortly after sunset. At one point he was nearly bitten by a bamboo viper, but had the presence of mind to avoid moving and giving up his position. As the General exited his encampment, Hathcock fired a single shot that struck the General in the chest, killing him.
