Thus, on the eve of New Year in that winter.
Beili and Great Yin simultaneously deployed forces for a pincer attack on Daxia.
The outbreak of war was sudden.
In the initial battles, Daxia suffered heavy losses, while the armies of both countries advanced smoothly.
In the north, facing Beili at Yanmen County, the majority of cities were lost within a few days.
The Beili army was halted only when reaching outside Yanmen County city.
As for Great Yin on the southeast side, progress was not smooth.
Although the Great Yin army acted unexpectedly, due to a previous successful sneak attack on Xiao Pass, Daxia was well-prepared. Despite the Great Yin army's overnight maneuvers, they were still detected by Daxia's scouts.
With the prepared Daxia Xiao Pass garrison, joined by Ba River Camp troops, they set an ambush at Xiao Pass, catching the Great Yin army off guard.
