Crossing the Great Q

Yang Lin picked out ten of the tallest men: "You ten, as shield bearers, hold your large shields in front. Your duty is to protect the spearmen and crossbowmen behind you!","You twenty men, as pikemen, wait until after you charge in. When you hear my order, when I shout 'thrust', then thrust your pikes forward; when I shout 'retreat', then pull back your pikes!",However, just as someone was about to speak, a loud shout rang out from within the ranks.。
