Poseidon of the East (29)
This chapter was perhaps inspired by Toyotomi Hideyoshi's campaign against the Mori clan in 1582. Under the direction of his chief strategist, Kuroda Kanbei, Hideyoshi's troops diverted the Ashimori River to flood Takamatsu Castle, the Mori's stronghold. The military term is mizuzeme (水攻め) or "attacking with water."
When Oda Nobunaga was assassinated by Akechi Mitsuhide in the midst of the battle, Hideyoshi quickly accepted the surrender of the Mori on generous terms (well, other than the castle lord, Shimizu Muneharu, having to commit seppuku) and stole a march on Mitsuhide, eventually defeating him at the Battle of Yamazaki.
