The allied armies of the local domains,…

The allied armies of the local domains, under the command of the Tokugawa shogunate with Itakura Shigemasa as commander-in-chief, now invest Hara Castle.

The swordsman Miyamoto Musashi is present in the besieging army, in an advisory role to Hosokawa Tadatoshi.

The army requests aid from the Dutch, who first give them gunpowder, and then cannons.

Nicolaes Couckebacker, Opperhoofd of the Dutch trading station on Hirado, provides the gunpowder and cannons, and when the shogunate forces requests that he send a vessel, he personally accompanies the vessel de Ryp to a position offshore, near Hara Castle.

The cannons sent previously are mounted in a battery, and an all-out bombardment of the fortress commences, both from the shore guns as well as from the twenty guns of the de Ryp.

These guns fire approximately four hundred and twenty-six rounds in the space of fifteen days, without great result, and two Dutch lookouts are shot by the rebels.

The ship withdraws at the request of the Japanese, following contemptuous messages sent by the rebels to the besieging troops: "Are there no longer courageous soldiers in the realm to do combat with us, and weren't they ashamed to have called in the assistance of foreigners against our small contingent?"

In an attempt to take the castle, Itakura Shigemasa is killed.

More shogunate troops under Matsudaira Nobutsuna, Itakura's replacement, soon arrives.
