In the meantime, a second Japanese army of approximately 20,000 man under the command of Kato Kiyomasa had caught up with Konishi's army at Mungyong, just north of Sangju, where the eastern and central routes to Hanseong merged. Kato was outraged that his rival, Konoshi, had disobeyed orders to wait for his arrival at Busan, and had instead advanced far ahead. Kato demanded that his forces now be allowed to take the lead and to capture Hanseong, but Konishi refused. The two armies crossed the Choryong Pass together and approached Chungju, where Kato suddenly announced that he would set up camp, hoping that Konishi would rush headlong into battle with Sin Rip's cavalry, making him look foolish and incompetent.
