賤ヶ岳の戦い
After the Incident at Honnō-ji in 1582, Hidetsugu was given a 400 thousand koku fiefdom in Ōmi Province because he was one of Hideyoshi's few relatives. In his subsequent career as a general, during Battle of Shizugatake 1583, he held Oiwayama-fort (Oiwayama-toride, 大岩山砦) with Takayama Ukon and Nakagawa Kiyohide and he sustained heavy losses in the Battle of Nagakute 1584 against Tokugawa Ieyasu.
