Ingram Plaza, located in San Diego on Liberty Station in front of the former Naval Training Center’s former base Command Center, is named for Osmond K. Ingram, the first U.S. Navy enlisted man killed in action during World War I. The monument, located in the plaza and dedicated to the heroic efforts of Gunner’s Mate Ingram, consists of a large natural stone with a bronze plaque.
Born in Alabama on August 4, 1887, Osmond Kelly Ingram had advanced to the rank of Gunner's Mate First Class and, during World War I, was serving on board the USS Cassin, a destroyer.
On 15 October 1917, while his ship was operating off the Irish coast, she was attacked by the German submarine U-61. Gunner's Mate Ingram spotted the incoming torpedo and, realizing that it would hit near the depth charges at the ship's stern, ran aft in an attempt to release them before the torpedo arrived. However, the torpedo struck the ship before he could release the depth charges and Ingram was killed in the ensuing explosion. For his extraordinary heroism on this occasion, he was posthumously awarded the Medal of Honor. In 1919, the USS Osmond Ingram (DD-255, and later AVD-9 and APD-35) was named in honor of Gunner's Mate First Class Osmond K. Ingram.
