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." Although Congress was responsible for the war effort and provided supplies to the troops, Washington took it upon himself to pressure the Congress and state legislatures to provide the essentials of war; there was never nearly enough. Congress evolved in its committee oversight and established the Board of War, which included members of the military. Because the Board of War was also a committee ensnared with its own internal procedures, Congress also created the post of Secretary of War, and appointed Major General Benjamin Lincoln in February 1781 to the position. Washington worked closely with Lincoln to coordinate civilian and military authorities and took charge of training and supplying the army. Continental Navy During the first summer of the war, Washington began outfitting schooners and other small seagoing vessels to prey on ships supplying the British in Boston. Congress established the Continental Navy on October 13, 1775, and appointed Esek Hopkins as its first commander; for most of the war, it consisted of a handful of small frigates and sloops, supported by numerous privateers. On November 10, 1775, Congress authorized the creation of the Continental Marines, forefather of the United States Marine Corps. John Paul Jones became the first American naval hero by capturing HMS Drake on April 24, 1778, the first victory for any American military vessel in British waters. The last was by the frigate USS Alliance commanded by Captain John Barry. On March 10, 1783, the Alliance outgunned HMS Sybil in a 45-minute duel while escorting Spanish gold from Havana to Congress. After Yorktown, all US Navy ships were sold or given away; it was the first time in America's history that it had no fighting forces
