Over twenty-seven thousand rebels face about one…

Over twenty-seven thousand rebels face about one hundred and twenty-five thousand shogunate soldiers by April 1638.

Desperate rebels mount an assault against them on April 4 and are forced to withdraw.

Captured survivors and the fortress's rumored sole traitor, Yamada Uemonsaku, reveal the fortress is out of food and gunpowder.

Troops under the command of the Kuroda clan of Hizen on April 12 storm the fortress and capture the outer defenses.

The rebels continue to hold out and cause heavy casualties until they are routed on April 15.

After the castle falls, the shogunate forces behead an estimated thirty-seven thousand rebels and sympathizers.

Amakusa Shirō's severed head is taken to Nagasaki for public display, and the entire complex at Hara Castle is burned to the ground and buried together with the bodies of all the dead.
