At this battle, the Americans had high ground atop a hill overlooking Boston to keep watch of the British troops in the city and to protect the hill from British take over. The British charged up the hill. The Americans were low on ammunition, so they were told "not to fire until you see the whites of their eyes!" The Americans ran out of ammunition, leading to their defeat, but it proved to the British that the Americans had a chance of winning the war.
