Colonel Jaime Sabater, Sr. (1904–1955), a United States Naval Academy graduate, Class of 1927, commanded the 1st Battalion, 9th Marines, 3rd Marine Division during the Bougainville amphibious operations. On November 1, 1943. The Allies intended to establish a beachhead around Cape Torokina, within which an airfield would be built. Allied forces did not plan, at that time, to try to capture the entire island of Bougainville from Japanese forces. An attempt by the Japanese Navy to attack the U.S. landing forces was defeated in the Battle of Empress Augusta Bay, between November 1 and November 2. A subsequent attempt by Japanese land forces to attack the Allied beachhead was defeated in the Battle of Koromokina Lagoon.
