A resident of Birmingham, Alabama, He had entered the Army 1 September 1942, and was a member of the 2nd Battalion, 29th Quartermaster Regiment. He was a passenger aboard the Dutch steamer USAT s'Jacob on 8 March 1943, which was near Porlock Harbor, New Guinea, when the ship was hit by Japanese bombers.
When the ship was abandoned, Watson remained in the water and, instead of trying to save himself, assisted soldiers who could not swim into life rafts.
Weakened by his exertions, he was dragged down by the suction of the sinking ship and drowned. His body was never recovered. (Other reports indicate that George Watson was brought onto HMAS Bendigo and was tried to be revived but could not. He was allegedly then buried at sea with full military honors.)
