《北史·列传·卷四十八》
李密暗中知道了这个情况，故意密而不发，想等王世充的军队一半渡过洛水，然后乘其立脚未稳再发起进攻。
密阴知之，不发其事，欲待世充兵半度洛水，然后击之。
Li Mi learned of this behind the scenes, and intentionally kept it a secret, wanting to wait until half of Wang Shichong’s army had crossed the Luo River, and then launch an attack while they were still getting their footing.
