Yoshihisa, seeing that Hideyoshi was prepared to invade, sent a message to Hideyoshi, claiming that he had attacked the other clans in self-defence, but Hideyoshi refused and leads his forces to Kyushu. Kyushu campaign In 1586, Kyushu Campaign by Toyotomi Hideyoshi begin. The Ōtomo forces led by Myorin, were supported by armies under Sengoku Hidehisa, Chōsokabe Motochika and Sogō Masayasu, delayed Shimazu forces and weakened them in preparation for the arrival of Hideyoshi's armies. Hideyoshi mobilised a force of 200,000 soldiers and 20,000 pack animals, transporting supplies for an even larger army of 300,000 men. Toyotomi Hidenaga led the vanguard of 25,000 men and 3,000 horses. By April 1587 Hideyoshi had reached the straits at Shimonoseki, moving through Chikuzen and Chikugo to attack Yoshihisa in Higo. At this point Mōri forces under Kobayakawa Takakage joined Hidenaga's force, as the Mōri had been recently suppressed. Hidenaga then drove back the Shimazu forces in Hyūga and Bungo. The Shimazu fought well, but had few firearms and lacked discipline and training; they were steadily overwhelmed through the superior quality and quantity. By the end of May 1587, the various island daimyos had turned to Hideyoshi's side. In June, Shimazu was routed in Satsuma itself, and Hideyoshi laid Siege of Kagoshima castle. Yoshihisa sued for peace, and a truce was agreed. Hideyoshi offered generous terms for a lasting peace to son of Yoshihiro's and Iehisa's; though Yoshihisa initially refused the offer, Hideyoshi tried again and was this time successful. After surrender Most of the domains Yoshihisa had conquered were given by Hideyoshi to three of his senior generals - Kato, Konishi, and Kuroda - and the Shimazu clan managed to retain only Satsuma Province and Ōsumi Province, as well as half of Hyuga. The Mori were given fiefs in northern Kyushu, and Kobayakawa gained Chikuzen. Yoshihisa shaved his head to surrender, showing that he would become a Buddhist monk if his life was spared. His name as a monk was Ryūhaku (龍伯) but it is unclear whether he retired in order to allow Yoshihiro to rule. As a retainer under Hideyoshi, his younger brother Yoshihiro controlled troops, but it is believed that Yoshihisa still managed day-to-day affairs in the domain. Yoshihisa did not have a son to succeed him, so he had Yoshihiro's son, Shimazu Tadatsune marry the third daughter Kameju (亀寿) and adopted him as the successor. Yoshihisa knowledge of culture is not
