Hours before Emperor Hirohito decreed Japan's World War II surrender 60 years ago, two Imperial army generals foiled a coup attempt by a dozen officers to block the historic broadcast.

On Aug. 15, 1945, nearly 1,000 soldiers occupied the Imperial Palace grounds for six hours from 2 a.m., aiming to seize two 25-cm records of the reading of the surrender decree and blocking its noon broadcast that day.

The actions of Lt. Gen. Takeshi Mori, commander of the First Imperial Guards Division, and Gen. Shizuichi Tanaka, commander of the Eastern Defense Command, enabled the monarch, known posthumously as Emperor Showa, to announce over the radio to the Japanese people and armed forces the nation's unconditional surrender.
