[Explanation]
Oshi castle appeared in “Nobouno Castle” that became a topic in the movie a few years ago.
It is a castle that has made his name familiar to the world under the opponent of Toyotomi Hideyoshi’s Kansai region army, even if main castle Odawara castle was still fighting, still continuing the battle against surrender.

While Toyotomi Hideyoshu surrounded Odawara Castle, it was Mitsunari Ishida of Hideyoshi’s aide who was ordered to attack this castle. Mitsunari was despised as a bad captain from Kiyomasa Kato and Masanori Fukushima.

Hideyoshi dared to order castle as supreme commander in order to make Mitsunari military exploits in this war.

However, the crucial Oshi castle was a natural haven surrounded by paddy fields and muddy fields.
There are no obstacles, but soldiers are hard to fall off from the castle because of not having any obstacles so they could see clearly.
Here, Mitsunari will imitate the massive floodwater that Hideyoshi had done at Bicchuu Takamatsu Castle before.

However, even though enormous breakwaters have been completed and the shipwrecks are immersed in water, it seems that the ruffled work that was built up by an overseer or originally instantly became a cornerstone, but fragile breakwaters are partly broken down.

A large amount of water flowed into itself in the Minari Army and many casualties occurred.
Odawara castle which is the main castle surrenders, and Oshi castle will leave its name as a castle which has continued to bask in the Odawara battle only to the last battle.

By the way, the castle owner of the castle at the time was Narita, that Uesugi Kensin also set up an attack twice, but he could not drop it again, raising it just by burning the castle.
