Biography of Rissai (Muneshige), vol.2/ Fukuoka Prefecture

This biography was written in 1689, fifty years after Tachibana Muneshige’s death. According to the book, Muneshige withdrew from Otsu-jo Castle due to the defeat of the western army at the Battle of Sekigahara on September 16th in 1600, and entered Kyoto. He then suggested staying in Osaka-jo Castle for resistance against the eastern army to his allies, Kinoshita Iesada and Mori Terumoto, of the western army. However, neither of them responded to it. He had no choice but to go back to Yanagawa of his domain.
Before sailing out from Osaka, he rescued his mother who was held hostage in Osaka-jo Castle. At a border station, his mother was not allowed to pass through, so they broke through the barrier, and finally arrived in Yanagawa-jo Castle on September 23rd.
