Each great samurai warlord, or daimyo, had a division of troops known as the Hatamoto, ‘those who stand under the flag’. The Hatamoto included the personal bodyguards, the senior generals, the standard bearers and color-guard, the couriers, and the other samurai under the warlord’s personal command. Apart from bodyguard and other duties in immediate attendance on the daimyo, both horse and foot guards often played crucial roles in battle. Their intervention could turn defeat into victory, and their collapse meant certain defeat. As favored warriors under the warlord’s eye, members of the bodyguards could hope for promotion, and a few even rose to be daimyo themselves. All the three great leaders of the 16 and 17th centuries – including Oda, Hideyoshi and Tokugawa – had their own elite corps. Such troops were naturally distinguished by dazzling apparel and heraldry, with banners both carried and attached to the back of the armor, all of which will be detailed in an array of color artwork specially created for this publication.
