During five war patrols under the command of Richard H. O'Kane, the Balao class fleet submarine U.S.S. Tang was credited with sinking a total of 31 Japanese ships, for a wartime total of 227,800 tons. The victim of a circular running torpedo during her fifth war patrol, only eight members of her crew, including O'Kane, survived to spend the rest of the war in Japanese captivity. This volume contains the complete text of Tang's five official war patrol reports. Also included is an Introduction, notes, and additional reference material.
