In Ch'ungch'ong province, the Abbot Yǔnggyu proved to be an active guerrilla leader and together with the Righteous Army of 1,100 commanded by Cho Hǒn attacked and defeated the Japanese at the Battle of Cheongju on 6 September 1592. After the victory, the Korean leaders began to quarrel among themselves over who was most responsible, and it was that when the Koreans took the offensive, the regulars under Yun Songak refused to take part while the Righteous Army under Cho and the warrior monks under abbot Yŏnggyu marched separately. On 22 September 1592, Cho with 700 Righteous Army guerrillas attacked a Japanese force of 10,000 under Kobayakawa Takakage. Turnbull described the Second battle of Geumsan as an act of folly on Cho's part as his outnumbered force took on "10,000 of the toughest samurai", who encircled the Righteous Army and "exterminated" them, wiping out the entire Korean force as Kobayakawa ordered that no prisoners be taken. Feeling obligated to come to Cho's aid, the Abbot Yǔnggyu now led his warrior monks against Kobayakawa at the third battle of Geumsan, who likewise suffered the same fate – "total annihilation". However, as the Geumsan salient had taken three successive Korean attacks in a row in a single month, the 6th Division under Kobayakawa was pulled back as Hideyoshi decided the salient was not worth the trouble to hold it, and to the suffering people of the region that was all that mattered. The Japanese withdrawal inspired further guerrilla attacks and one Righteous Army leader, Pak Chin, had an object hurled over the walls of the Japanese-held town of Kyǒngju, which caused "the robbers" as Korean accounts always called the Japanese to go examine it; the object turned out to be a bomb that killed 30 Japanese. Fearing his garrison was now under-strength, the Japanese commander ordered a retreat to the coastal "wajo" at Sŏsaengp'o.
