Hasedō

The Battle of Hasedo (長谷堂の戦い), also called Siege of Hasedo, is one of the battles that took place during the Sekigahara campaign. The Uesugi army in northern Japan sieges Hasedo castle, which is guarded by Date-Mogami alliance. However, the siege fails and Uesugi army withdraws as news of Ieyasu's victory at Sekigahara spreads.

Samurai Warriors
The battle first appears in Samurai Warriors 2. The Uesugi side are first shown to be successful in the siege, but the shocking news of Mitsunari's defeat at Sekigahara forces them to stop the siege and flee to escape point. Early during the retreat, Keiji convinces Kanetsugu not to worry anymore of the loss of Mitsunari, but instead focus on the battle that lies in front of them. After passing three gates, they are ambushed, but Keiji holds the rearguard and closes the third gate just after Kanetsugu and the others pass it. Kanetsugu praises his actions and just as they are about to escape safely, the main Date army appears and Masamune insults Kanetsugu for his constant talking about honor. After defeating both Yoshiaki and Masamune, the road to escape point is secured.

The Date version focuses on pursuing the fleeing Uesugi army. Should Masamune fail to catch Kanetsugu, the battle is lost. The route through the area is slightly different as certain gates won't open at all, forcing Masamune to take a longer route in some cases.

In Samurai Warriors 3, the battle is somewhat different as it is a siege-turned-retreat. In addition, both armies receive new allies, Aya appears on the Uesugi army while Magoichi aids Masamune.
