Siege of Hasedō
Hasedō Castle, Yamagata, Japan
What happened
In 1600 Japan's lords split between Tokugawa Ieyasu's Eastern side and Ishida Mitsunari's Western side. In the north, the Western-allied Uesugi marched toward Yamagata and besieged Hasedō Castle. Date troops broke through to help the defenders, and a full Uesugi assault failed.
Why it matters
Why it matters: It stopped the Uesugi advance toward Yamagata and ended Uesugi campaigns in the north. It was fought at the same time as the decisive Sekigahara campaign far to the south.
What came next
When news came of Ieyasu's victory at Sekigahara, Naoe ordered a full withdrawal. In 1601 the Uesugi lands were cut down to the much smaller fief of Yonezawa.
Did you know?
Fighting at Hasedō went on for a while even after news of Ieyasu's victory arrived.
