Bai Qi
Bai Qi was furious at this because he believed Qin had just forfeited a chance to annihilate Zhao once and for all, and resigned his position in protest. However, Zhao soon changed its mind and refused to cede the lands it promised, and attempted to lobby an anti-Qin alliance with the other states. King Zhaoxiang then ordered an attack on Zhao in late 259 BC, laying siege to Handan. He wanted Bai Qi to lead the attack, but the still angry Bai Qi bluntly refused to assume the position citing illness. Instead, he advised King Zhaoxiang to call off the siege as the window of opportunity for an easy victory was already gone, because Lord Pingyuan had managed to secure military reinforcements from Chu and Wei, led by the famous Lord Chunshen and Lord Xinling. King Zhaoxiang did not take in his advice and instead appointed Wang Ling (王陵) as the commander of the siege.
