chunk: As the Imperial Army marches against the Samurai, a grieving Katsumoto contemplates seppuku, but Algren convinces him to fight until the end, and joins the Samurai in battle. Citing the Battle of Thermopylae, the Samurai use the Imperial Army's overconfidence to lure their soldiers into a trap and deprives them of artillery support. The ensuing mĂŞlĂŠe battle inflicts massive casualties and forces the Imperial soldiers to retreat. Knowing that Imperial reinforcements are coming and defeat is inevitable, Katsumoto orders a suicidal charge on horseback into machine-gun fire. In the chaos, Algren kills Bagley. Moved by the sight of the dying samurai, the Imperial captain, previously trained by Algren, disobeys Omura and orders the Army's guns to cease fire. A mortally-wounded Katsumoto commits seppuku with Algren's help, as the Imperial Army kneels in respect for the dead.
