Between March 3 and April 1, 200, Yuan Shao sent his general Yan Liang with Guo Tu and Chunyu Qiong across the river to attack Liu Yan's position at Boma, while Yuan stayed behind at Liyang with the main army to give the impression that he was crossing the river. Earlier, Yuan Shao's advisor Ju Shou had objected to letting Yan Liang lead the attack, saying that Yan Liang was brave but impatient and unable to manage the task alone, but Yuan Shao ignored his advice.
