Yuan Hao
Yuan Tianmu's 300,000 men never arrived at Xinyang. Luoyang, the capital of Northern Wei, was taken by Yuan Hao rather than Chen. Yuan Hao wasn't a puppet of Chen and probably had a bigger army. Yuan Tianmu debated with his staff and court dignitaries on whether to take Luoyang back right away, or to follow the fleeing Wei emperor north which he went with.
