《梁书·列传·卷十一》
当各地义兵举事反齐时，高祖在夜裹召集吕僧珍和张弘策共同商议计策。第二天早晨就集合部队，把檀溪中的木材、竹子都捞取上来，制造成楼船战舰，用茅草把它们全都遮盖起来，这些事没多久就办好了。
义兵起，高祖夜召僧珍及张弘策定议，明旦乃会众发兵，悉取檀溪材竹，装为艛舰，葺之以茅，并立办。
When local righteous soldiers took action to resist Qi, Gaozu summoned Lü Sengzhen and Zhang Hongce at night to discuss strategies. The next morning, he assembled his troops, fished out the wood and bamboo in Tanxi, built them into battleships, and covered them with reeds. These tasks were completed in no time.
