In an action during the American Revolution, a mounted American officer was on the point of being made prisoner. To escape, he had to go along the front of the British line, within musket range. He took the risk, and although a whole brigade fired at him, both man and horse escaped with impunity.
And at the siege of Yorktown, British soldiers had each three bags of sand to cover themselves from the enemy's aim. Two of these were placed with their ends at a little distance from each other, and the third crossed over the interval, leaving a small hole for the soldiers to fire through. The American riflemen, however, were so expert that, on seeing a piece protruded through the hole, they levelled towards it, and frequently shot the men through the head.
美國獨立戰爭一場戰事之中，一個騎着馬的美國軍官勢將被擒，要脫身，必須在英軍陣前走過，而且是在英軍毛瑟槍射程之內。他冒險策馬向前。一旅英軍一起向他開火，卻都沒有打中，人馬安然逃脫。
而在約克敦圍城戰之中，每個英軍士兵都有三個沙包，防禦敵軍槍火。他們左右各放一個沙包，兩個沙包的一端幾乎相接，第三個沙包則放在兩者之間，只留下一個小孔，從這個小孔開槍。但美軍的來福槍手十分厲害，看見有槍管從小孔伸出來，就瞄準小孔開槍，每每射穿英軍士兵的頭顱。
