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, and Katō Kiyomasa's men departed for Japan shortly afterward. Hachisuka Iemasa and Kuroda Yoshitaka were reported by Nagataka Fukuhara for not pursuing the allied army, which incurred the wrath of Toyotomi Hideyoshi.
