Sassa Narimasa
After Nobunaga's assassination at Honnō-ji (本能寺) by Akechi Mitsuhide and Mitsuhide's subsequent defeat by Hideyoshi, he battled Hideyoshi under Shibata's command in the Battle of Shizugatake 1583. After Shibata's defeat, Toshiie worked for Hideyoshi and became one of his leading generals. Somewhere during this time he was forced to fight another of his friends, Sassa Narimasa. Narimasa was greatly outnumbered and felled by Toshiie, following the major Maeda victory at the Battle of Suemori Castle 1584. Later, he fought in the Odawara Campaign 1590.
