paragraph_text: Valley Forge and Monmouth
  
  Washington and his Continental Army of 11,000 men went into winter quarters at Valley Forge north of Philadelphia in December 1777. There they lost between 2,000 and 3,000 men as a result of disease and lack of food, clothing, and shelter. The British were comfortably quartered in Philadelphia, paying for supplies in pounds sterling, while Washington struggled with a devalued American paper currency. The woodlands were soon exhausted of game. By February, Washington was facing lowered morale and increased desertions among his troops.
  
  An internal revolt by his officers, led by Major General Thomas Conway, prompted some members of Congress to consider removing Washington from command. Washington's supporters resisted, and the matter was dropped after much deliberation. Once the plot was exposed, Conway wrote an apology to Washington, resigned, and returned to France.
  
  Washington made repeated petitions to Congress for provisions. He received a congressional delegation to check the Army's conditions and expressed the urgency of the situation, proclaiming: "Something must be done. Important alterations must be made." He recommended that Congress expedite supplies, and Congress agreed to strengthen and fund the army's supply lines by reorganizing the commissary department. By late February, supplies began arriving. Meanwhile, Baron Friedrich Wilhelm von Steuben 's incessant drilling transformed Washington's recruits into a disciplined fighting force by the end of winter camp. For his services, Washington promoted Von Steuben to Major General and made him chief of staff.
  
  In early 1778, the French responded to Burgoyne's defeat and entered into a Treaty of Alliance with the Americans. Congress ratified the treaty in May, which amounted to a French declaration of war against Britain. In May 1778, Howe resigned and was replaced by Sir Henry Clinton.
  
  The British evacuated Philadelphia for New York that June and Washington summoned a war council of American and French generals. He chose a partial attack on the retreating British at the Battle of Monmouth. Generals Charles Lee and Lafayette moved with 4,000 men, without Washington's knowledge, and bungled their first attack on June 28. Washington relieved Lee and achieved a draw after an expansive battle. At nightfall, the British continued their retreat to New York, and Washington moved his army outside the city. Monmouth was Washington's last battle in the North.
