At Osaka Castle, Tokugawa Yoshinobu gathered his advisors and military leaders to plan strategy and, to boost morale, advised that he would personally take to the field as commander of "bakufu" forces. That evening however, he slipped away from Osaka Castle accompanied by the "daimyōs" of Aizu and Kuwana to escape back to Edo on the shogunate warship "Kaiyō Maru".
