《旧唐书·列传·卷十七》
李密就派遣李勣率领部下五千士兵从原武渡过黄河突袭黎阳仓，当天就占领了它，开仓听任饥民领粮，十天之内，兵力发展到二十多万。
密乃遣勣领麾下五千人自原武济河掩袭，即日克之，开仓恣食，一旬之间，胜兵二十万余。
Li Mi sent Li Ji to lead five thousand soldiers from Yuanwu to cross the Yellow River and raid the Liyang warehouse. He occupied it that day, opened the warehouse and let the starving people take the grain. Within ten days, his forces grew to more than two hundred thousand.
