Ch. 401An army at the gates, Yelü Dafeng's decision
Lin Yi sent the Tiger and Leopard Cavalry and White Horse Volunteers toward Wind and Snow City while Ma Chao also mobilized, forcing Yelü Dafeng to prepare for a three-pronged assault. Yelü Dafeng chose to hold the position and await reinforcements as the Tiger and Leopard Cavalry arrived.
- Jia Xu explained that Bai Zizai would be saved for the attack on the enemy royal city, and Lin Yi set out to watch the Tiger and Leopard Cavalry's first battle at full strength.
- Yelü Dafeng heard a thunderous approach near Wind and Snow City, sent scouts to investigate, and ordered his army onto alert.
- Scouts reported that the Tiger and Leopard Cavalry and White Horse Volunteers were advancing with roughly a hundred thousand troops each, while Ma Chao had also moved out.
- Yelü Dafeng rejected retreat, ordered his troops to use the wooden palisades and chevaux-de-frise for cover, and sent for reinforcements.
- The Tiger and Leopard Cavalry arrived, and one of Yelü Dafeng's deputies questioned why they were attacking head-on instead of the Xiliang Iron Cavalry.
