Submarines are very valuable attack vehicles. In WWII they were basically surface ships that could travel underwater for a limited time. The submarines of the United States were already very advanced and won the Pacific theatre. Charles Mc Henry (Avril 20, 1924 – December 19, 2011) served in the U.S. Navy during WWII aboard the submarine U.S.S. Finback. She arrived at Pearl Harbor in May 1942 and was dispatched to the Midway area in anticipation of a Japanese attack. Between 1942 and the end of the war, she embarked on 12 war patrols, 9 of which were designated successful. She sank a total of 69,383 tons of enemy shipping during the war, and rescued, among other downed aviators, future President of the United States George Bush.
