The total number was about 130 plus 22 farmers who joined at Hino where Hijikata Toshizo's home town was located. When they arrived at Komagai, Oishi Kuwajiro who had been sent for scouting brought shocking news the Imperial troops already entered Kofu castle which the Koyo Chinbutai was going to take. (3/4) Next day Hijikata went back to Edo to bring reinforcements but the Imperial troops and the Koyo Chinbutai clashed at Kashiwao on 3/6.
