[3] News of the Japanese defeat at the Battle of Hansando reached Busan within hours and two Japanese commanders, Kuki Yoshitaka and Kato Yoshiaki, immediately set sail with 42 ships for the port of Angolpo, where they hoped to face the Korean fleet close to shore.
He told his commanders that he would come to Korea personally to lead the naval forces himself, but Hideyoshi was never able to carry through on this as his health was deteriorating rapidly.
This meant that all the fighting would be in Korea, not China, and that Pyongyang would be the furthest northwestern advance of the Japanese armies (to be sure, Katō Kiyomasa's second contingent's brief march into Manchuria was Japan's northernmost advance, however, Manchuria was not a part of Imperial China in the 16th century).
While Hideyoshi was unlikely to be able to invade China and conquer a large part of it, the battles of Hansan Island and Angolpo checked his supply routes and hindered his movements in Korea.
Hideyoshi's larger war plans, supported in much written documentation, was nearly identical to Imperial Japan's blueprint for conquest in the 20th century.
