conquered several minor locations on Kyūshū, and Nabeshima Katsushige, whose family had defected to the Tokugawa. The two then began the siege of Yanagawa in Chikugo Province, defended by Tachibana Muneshige and Tachibana Ginchiyo. The Tachibana troops continued to hold out in the castle, with Ginchiyo organising an ad-hoc militia of nuns to slow the advance of the Eastern Army, donning armour herself to serve as Muneshige's rearguard. Muneshige eventually surrendered the castle following the suggestion that he defect to the Eastern Army in order to attack the Shimazu clan, their long-time rivals; however, Ieyasu instituted a plan of appeasement for the Shimazu to prevent unrest following their defeat at Sekigahara, and so forbade any further action against them.
