Later Yan
Tuoba Gui arrived west of Canhe Slope at dusk on December 7, with Later Yan forces east of Canhe Slope and not realizing Northern Wei forces had arrived. Tuoba Gui kept his army in full silence and, in the night, set up positions on the hills around the Later Yan encampment. On December 8, at sunrise, Northern Wei forces launched their attack, surprising Later Yan forces.
