"That son of a bitch will not be dictating any peace terms in the White House." -- Captain Thomas G. Lanphier, Jr., 339th Fighter Squadron, to Guadalcanal fighter director at Henderson Field just before landing after the aerial assassination of Admiral Isoroku Yamamoto in Operation Vengeance.

Operation Vengeance was carried out to kill Japanese Admiral Isoroku Yamamoto on April 18, 1943, during the Solomon Islands campaign in the Pacific Theater of World War II. Isoroku Yamamoto, commander of the Combined Fleet of the Imperial Japanese Navy, was killed on Bougainville Island when his transport bomber aircraft was shot down by U.S. Army fighter aircraft operating from Henderson Field on Guadalcanal.
The mission of the U.S. aircraft was specifically to kill Yamamoto and was based on United States Navy intelligence on Yamamoto's travel plans in the Solomon Islands area. The death of Yamamoto reportedly damaged the morale of Japanese naval personnel (described by Samuel Eliot Morison as being considered the equivalent of a major defeat in battle), aided the morale of members of the Allied forces, and, controversially, may have been intended as an act of revenge by U.S. leaders who blamed Yamamoto for the Pearl Harbor attack which initiated the formal state of war between Imperial Japan and the U.S.
