Who is regarded as Japan's second "great unifier", and is reponsible for taking Miki Castle of Harima Province from Bessho Nagaharu?
Toyotomi Hideyoshi Toyotomi Hideyoshi (豊臣 秀吉 , March 17, 1537 – September 18, 1598) was a preeminent "daimyō", warrior, general, samurai, and politician of the Sengoku period who is regarded as Japan's second "great unifier". He succeeded his former liege lord, Oda Nobunaga, and brought an end to the Warring States period. The period of his rule is often called the Momoyama period, named after Hideyoshi's castle. After his death, his young son Hideyori was displaced by Tokugawa Ieyasu.
Siege of Takamatsu In the 1582 siege of Takamatsu (備中高松城の戦い), Toyotomi Hideyoshi laid siege to Takamatsu Castle, which was controlled by the Mōri clan. He diverted a nearby river with dikes to surround and flood the castle, leading to a relatively speedy surrender. He also constructed towers on barges from which his arquebusiers could keep up a constant rate of fire and be unhindered themselves by the flooding. As the battle grew more intense, the garrison received reinforcements from the Mōri, Kikkawa and Kobayakawa clans, and Hideyoshi sent for aid from his lord Oda Nobunaga. In response, Nobunaga sent a contingent of men west, to make their way to Takamatsu, while he himself stopped at the Honnō-ji for a time; during this stay, he would be betrayed and killed by Akechi Mitsuhide.
