上田城
Fortifying Ueda Castle, Masayuki fought against Tokugawa Hidetada's 38,000 men with only 2,000 soldiers. This was the Second Battle of Ueda Castle, and, whilst it was not exactly a victory, Masayuki was able to deliver a heavy blow to Hidetada and delay his forces for long enough that they were unable to show up at the main battlefield on time.
