INTERACTIVE BATTLE
11 June 1583 · Shizugatake and Lake Yogo, Omi Province
The decisive clash between Hashiba Hideyoshi and Shibata Katsuie over Nobunaga’s succession. After a long standoff across Lake Yogo, Sakuma Morimasa’s surprise attack set the battle in motion, and Katsuie took his own life at his home castle of Kitanosho.
After the Honnoji Incident, the Kiyosu conference failed to settle who would succeed Nobunaga or how his lands would be divided. Hideyoshi secured Omi while Katsuie came south from Echizen, and the two armies faced each other around Lake Yogo. Oda Nobutaka and Takigawa Kazumasu rose in support of Katsuie, forcing Hideyoshi to hold a second front in Mino.
Katsuie fell back to Kitanosho and killed himself, and Oichi died with him. Nobutaka and Kazumasu also submitted, and Hideyoshi secured his standing as Nobunaga’s successor.

Sakuma Morimasa takes Oiwayama fort
Hideyoshi turns back from Ogaki to Kinomoto
Hideyoshi, then in Mino, turned about the moment word reached him and was back on the field the same day. The forced march is remembered as the "great return from Mino", and it left Morimasa no time to pull back.
Points of debate
The distance covered and the time taken vary between sources, and some hold that the account contains later exaggeration.

Katsuie’s army breaks at Shizugatake
Hideyoshi’s men pressed the attack around Shizugatake and Katsuie’s army collapsed. The work of young commanders such as Kato Kiyomasa would later be told as the feat of the Seven Spears.
Points of debate
The grouping of "seven spears" was tidied up by later writers, and the number and names of those who distinguished themselves are disputed.
