The samurai invasion had gone well, overcoming any opposition in the south of the country. Konishi Yukinaga and his army continued there rapid approach to Seoul. The last Korean force to stand in the way of Konishi was Sin Ip's. Sin Ip choose not to stop the samurai at the Choryang pass, choosing instead to meet them on the plain of Chungju. Placing his army on a hill with the mighty Han river to his back Sin Ip believed the plain would be ideal for his cavalry.
Sin Ip placed his cavalry(2 standard and 1 small unit of medium cav) on his right wing under Yi Il. On his left was Jin Ru-wen withhis division(2 standard unit medium inf, 1 standard unit light inf and 1 standard unit archers), in the centre was Sin Ip himself(1 units standard medium inf, 1 unit Standard light inf, 1 unit standard archers and 1 light artillery piece)
Konishi set up with So Yoshitomo( 2 standard units medium inf, 1 sandard unit heavy inf) on the left, he was to hold his ground and wait for the Korean Cavalry. On Konishi's right was Matsuura Shigenobu( 1 standard unit heavy inf, 1 standard unit medium inf, 1 standard unit arquebus and 1 standard unit heavy cav), Matsuura was to attack with haste and hopefully fold the Korean left flank. In the centre was Konishi( 1 standard unit heavy inf, 1 standard unit medium inf with pikes and 2 standard units arquebus) he was to support his right flank when needed.
So Yoshitomo got off to a great start, his division moved quick, the commander was well respected by his troops and managed to move within bow range of the Koreans in two moves. Yi Il struggled to get his cavalry division moving feeling safer on the hill than down on the plain, no matter how hard he tried to move his men they were stubborn deciding only to move to the bottom of the hill and see what happens.
