Camp Pendleton hosts the 72nd Anniversary of the Battle of Iwo Jima Commemoration tour and dinner. February 19,1945 marked the beginning of the Battle of Iwo Jima. Japanese soldiers turned the volcanic island into a trap, fighting from a maze of tunnels and steel bunkers beneath Mt. Suribachi. The Battle of Iwo Jima lasted 36 days and resulted in heavy casualties before the Marines secured the island.
