The Siege of Takamatsu took place in 1582 in Japan.

Toyotomi Hideyoshi was attacking the Mori castle of Takamatsu when news of Oda Nobunaga's murder reached him. Hideyoshi had already diverted a river to flood the castle and when he suggested a negotiated end to the siege, the Mori (who were unaware of Oda's murder) were willing to listen. They surrendered the castle, freeing Hideyoshi to immediately leave to pursue Oda's assassin, Akechi Mitsuhide.
