Mao Wenlong vs Minamoto no Yoriyoshi

Mao Wenlong was appointed commander of Ming forces on Pi Island (now in North Korea), a strategic base for harassing the Later Jin (Manchu) forces. He built a fortified position that threatened Manchu supply lines and coastal areas.

Mao Wenlong led raids from Pi Island against Manchu coastal settlements, disrupting their logistics and tying down Manchu forces. These operations provided some relief to Ming armies fighting on the Liaodong front.

Ming general Yuan Chonghuan, suspecting Mao Wenlong of treason and unauthorized dealings with the Manchus, executed him on Pi Island. The execution removed a key Ming commander but also demoralized the Ming military and weakened defenses against the Manchus.

Minamoto no Yoriyoshi was appointed Chinjufu Shogun, commander-in-chief for the defense of northern Japan. This appointment placed him in charge of military operations against the Abe clan in the Mutsu Province, initiating the Former Nine Years War.

Yoriyoshi's forces attacked the Abe clan stronghold at Kawasaki Fortress in Mutsu Province. The battle was a costly victory for the Minamoto, with heavy casualties on both sides, but it weakened Abe resistance and demonstrated the difficulty of the campaign.

Yoriyoshi led a prolonged siege of the Abe clan's fortress at Kuriyagawa. After a difficult campaign, he captured the fortress and killed the Abe leader, Abe no Sadato, effectively ending the Former Nine Years War and securing Minamoto dominance in the north.
