佐佐成政
During the Siege of Uozu in March 1582, Shibata Katsuie seized Uozu Castle after a three-month battle; however, the same day as his victory, Oda Nobunaga was assassinated in the Honnō-ji Incident and he was forced to withdraw before taking Matsukura Castle. In 1583, Sassa Narimasa returned at the head of a new army and Matsukura Castle was reduced.
