In 1545-1546 Uesugi Tomomasa, With the assistance of his powerful relative Uesugi Norimasa and the Kamukura shogun, Ashikaga Haruuji, besieged the strategically important Kawagoe Castle, then held by the Hojo clan. Despite an overwhelming attacking force, the Kawagoe Castle”s garrison, led by Hojo Tsunashige, held out until a relief force arrived. That relief force was led by Tsunashige”s brother, Hojo Ujiyasu. A single warrior was sent to sneak past the Uesugi siege lines to inform the garrison of the relief's arrival. Though still strongly outnumbered, ninja spies informed the Hojo forces that the attackers, Ashikaga Haruuji in particular, had relaxed their vigilance due to their overconfidence in victory. The Hojo tried a risky tactic, coordinating a night attack between the garrison and the relieving force. The Uesugi were totally surprised, thrown into confusion, and routed. This was Hojo Ujiyasu”s greatest victory and one from which the Uesugi never recovered.
