World War II involved combatants from most of the world’s nations and was considered the deadliest war in history. Around 85 million military and civilians died as a result. The end finally came on Sept. 2, 1945, when Japanese officials signed the surrender documents aboard the battleship USS Missouri at Tokyo Bay, Japan.
