The USS Grenadier (SS-210) was a Gato-class submarine of the United States Navy that served during World War II. The submarine was laid down in 1940 and commissioned in 1941. It participated in multiple war patrols in the Pacific Ocean, where it engaged in combat operations against Japanese forces. In April 1943, the USS Grenadier was damaged by depth charges and subsequently sunk by the Japanese destroyer Harukaze. The crew was taken as prisoners of war, enduring harsh conditions and mistreatment at the hands of their captors. After the war, some of the survivors testified against their captors during war crimes trials. The sinking of the USS Grenadier is commemorated as a significant event in the history of the submarine service and serves as a reminder of the sacrifices made by submariners during World War II.
