Feng Yun pondered.
The Jin and Qi armies had no differences in weaponry.
It then came down to the strength of each side.
More men naturally meant greater strength.
But siege warfare had always been the most difficult.
The trenches of Bingzhou were over ten feet deep and three feet wide, with the bottoms filled with sharp caltrops and the moat notoriously broad. The Qi Army wouldn't even be able to touch the city gates without filling in the trenches and the moat...
Therefore, even with a force several times the size of the Beiyong Army, it was wishful thinking for the Qi Army to take Bingzhou City in a short period of time.
Moreover, in a siege, the attackers would suffer far greater casualties than the defenders.
It was for that reason Xiao Cheng waited so many days at Hengqu Pass, besieging without attacking.
