Takeda Katsuyori inherited leadership of the Takeda after his father Shingen had died. Personally brave and frequently showing good leadership in battle, he is still held responsible for the fall of the Takeda after the disastrous Battle of Nagashino in 1575.
In the Koyo Gunkan, Katsuyori is contrasted with his father; Shingen possesses all the qualities a successful clan leader must have, while Katsuyori fails in several respects.
Takeda Katsuyori had two personal banners (uma jirushi), in reverse colours but otherwise identical to each other. His banners bore the character "tai" (or "dai"), which means "great".
The sashimono (back banner) used by Takeda Katsuyori's followers had his mon, which was the straight-edged Takeda mon. Logically this should be either white on black or in reverse colours; I have not been able to determine which one it was. I chose black on white since Takeda Nobutoyo, who was found in the same command as Katsuyori on at least one occasion (Mikata Ga Hara), logically should use a white on black Takeda mon.
Takeda Katsuyori. I have taken the colours on his armour from a painting which I'm unfortunately unsure of the authenticity of (sigh). The impressive figure I used is from AIM's "mounted high command" pack; their figures are IMO somewhat large for the scale.
