The fighting lasted for twelve years, or nine if one subtracts short periods of ceasefire and peace. Skirmishes were fierce and many, but few major battles were fought until the
Battle of Kawasaki in 1057. Abe no Yoritoki had been killed shortly before, and the Minamoto were now fighting his son,
Abe no Sadato, who defeated them at Kawasaki and pursued them through a blizzard. The government forces, led by the Minamoto, had much trouble for quite some time, due to the harsh terrain and weather, but were eventually reinforced with new troops, including many offered by the Governor, a member of the
Kiyohara clan, of the nearby
Dewa Province. In 1062, Minamoto no Yoriyoshi, along with his son, led an assault on an Abe fortress at
Siege of Kuriyagawa. They diverted the water supply, stormed the earthworks and stockade, and set the fortress aflame. After two days of fighting, Sadato surrendered. == Legacy ==
