Second siege of Ulsan

The allied army, number 29,500 men, laid siege to Tosan near Ulsan in late October. The fortress was too heavily fortified to attempt an assault, however a series of engagements did occur around the area, resulting in more than 2,000 Japanese casualties. Allied forces lifted the siege on 2 November. Katō Kiyomasa's men departed for Japan on 14 December 1598. Although the battle was ended in complete victory for the Japanese forces, their commanders such as Hachisuka Iemasa and Kuroda Yoshitaka were not pursuing the battered Ming army. Their action were reported by Nagataka Fukuhara, which incurred the wrath of Toyotomi Hideyoshi.
