The PVA XIII Army Group apparently was still on the east central front, its 40th Army astride Route 17 just above Chuncheon and the 39th Army next to the east with its bulk between the Hwacheon Reservoir and the Soyang River and light forces occupying a bridgehead below the Soyang between Chuncheon and the river town of Naep'yong-ni some 10 miles upstream to the northeast.
