Michitarō Mizushima

Near the end of Japanese civil war, several disgraced ronin living in Edo's red light district attempt to regain their honor by defending a brothel from a hostile militia bent on wiping out local prostitutes.

A sadistic Daimyo (feudal lord) rapes a woman and murders both her and her husband, but even when one of his own vassals commits suicide to bring attention to the crime, the matter is quickly hushed up. Not only will there be no punishment, but because the Daimyo is the Shogun's younger brother, he will soon be appointed to a high political position from which he could wreak even more havoc. Convinced that the fate of the Shogunate hangs in the balance, a plot is hatched to assassinate the Daimyo. The two most brilliant strategic minds of their generation find themselves pitted against each other; one is tasked to defend a man he despises, and has a small army at his disposal. The other is given a suicide mission, and has 12 brave men. They are the 13 Assassins.

The Americans are swiftly closing on Okinawa, an island just south of the Japanese mainland. The Imperial command sends top generals and several army divisions to defend it at all costs. The mission quickly degenerates as vital resources and troops are diverted to other islands. After a civilian evacuation ends in tragedy most of non-combatants are forced to remain on the island. Many convert to soldier status. Tokyo sends mixed messages that squander time and resources, as when they order the defenders to build an airstrip for aircraft that never come. The truth soon becomes obvious: the high command decides that the island cannot be held and effectively abandons the Okinawan defenders. When the Americans land many troops are deployed in the wrong places. As the slaughter mounts, a suicidal attitude takes hold. Okinawa becomes a death trap, for civilian volunteers and non-combatants as well.
