 Yuan Shao thus appointed Meng Dai as his new army supervisor and ordered him to replace Shen Pei as the officer guarding his home base in Ye (present-day Handan, Hebei).In 202, two years after his disastrous defeat at the Battle of Guandu, Yuan Shao died without clearly naming one of his sons as his successor.A power struggle thus broke out between two of his sons, Yuan Tan and Yuan Shang, over the succession.
