As a whole, American officers never equaled their opponents in tactics and maneuvers, and they lost most of the pitched battles. The great successes at Boston (1776), Saratoga (1777), and Yorktown (1781) were won from trapping the British far from base with a greater number of troops. Nevertheless, after 1778, Washington's army was transformed into a more disciplined and effective force, mostly by Baron von Steuben's training. Immediately after the Army emerged from Valley Forge, it proved its ability to match the British troops in action at the Battle of Monmouth, including a black Rhode Island regiment fending off a British bayonet attack then counter-charging for the first time in Washington's army. Here Washington came to realize that saving entire towns was not necessary, but preserving his army and keeping the revolutionary spirit alive was more important in the long run. Washington informed Henry Laurens "that the possession of our towns, while we have an army in the field, will avail them little."
