paragraph_text: Crossing the Delaware, Trenton, and Princeton
  
  Washington crossed the Delaware River into Pennsylvania, where Lee's replacement General John Sullivan joined him with 2,000 more troops. The future of the Continental Army was in doubt due to lack of supplies, a harsh winter, expiring enlistments, and desertions. Washington was disappointed that many New Jersey residents were Loyalists or skeptical about independence.
  
  Howe split up his army and posted a Hessian garrison at Trenton to hold western New Jersey and the east shore of the Delaware. Desperate for a victory, Washington and his generals devised a surprise attack on Trenton. The army was to cross the Delaware in three divisions: one led by Washington (2,400 troops), another by General James Ewing (700), and the third by Colonel John Cadwalader (1,500). The force was to then split, with Washington taking the Pennington Road and General Sullivan traveling south on the river's edge.
  
  Washington ordered a 60-mile search for Durham boats to transport his army, and the destruction of vessels that could be used by the British. He personally risked capture while staking out the Jersey shoreline alone leading up to the crossing. Washington crossed the Delaware on Christmas night, 1776. His men followed across the ice-obstructed river from McConkey's Ferry, with 40 men per vessel. The wind churned up the waters, and they were pelted with hail, but by 3:00 a.m. on December 26, they made it across with no losses. Knox was delayed, managing frightened horses and about 18 field guns on flat-bottomed ferries. Cadwalader and Ewing failed to cross due to the ice and heavy currents. Once Knox arrived, Washington proceeded to Trenton, rather than risk being spotted returning his army to Pennsylvania.
  
  The troops spotted Hessian positions a mile from Trenton, so Washington split his force into two columns, rallying his men: "Soldiers keep by your officers. For God's sake, keep by your officers." The two columns were separated at the Birmingham crossroads. General Greene's column took the upper Ferry Road, led by Washington, and General Sullivan's column advanced on River Road. The Americans marched in sleet and snowfall. Many were shoeless with bloodied feet, and two died of exposure. At sunrise, Washington, aided by Colonel Knox and artillery, led his men in a surprise attack on the unsuspecting Hessians and their commander, Colonel Johann Rall. The Hessians had 22 killed, including Colonel Rall, 83 wounded, and 850 captured with supplies.
  
  Washington retreated across the Delaware to Pennsylvania and returned to New Jersey on January 3, 1777, launching an attack on British regulars at Princeton, with 40 Americans killed or wounded and 273 British killed or captured. American Generals Hugh Mercer and John Cadwalader were being driven back by the British when Mercer was mortally wounded. Washington arrived and led the men in a counterattack which advanced to within 30 yards (27 m) of the British line.
  
  Some British troops retreated after a brief stand, while others took refuge in Nassau Hall, which became the target of Colonel Alexander Hamilton 's cannons. Washington's troops charged, the British surrendered in less than an hour, and 194 soldiers laid down their arms. Howe retreated to New York City where his army remained inactive until early the next year. Washington took up winter headquarters in Jacob Arnold's Tavern in Morristown, New Jersey, while he received munition from the Hibernia mines. While in Morristown, Washington's troops disrupted British supply lines and expelled them from parts of New Jersey.
  
  During his stay in Morristown, Washington ordered the inoculation of Continental troops against smallpox. This went against the wishes of the Continental Congress who had issued a proclamation prohibiting it, but Washington feared the spread of smallpox in the army. The mass inoculation proved successful, with only isolated infections occurring and no regiments incapacitated by the disease.
  
  The British still controlled New York, and many Patriot soldiers did not re-enlist or deserted after the harsh winter campaign. Congress instituted greater rewards for re-enlisting and punishments for desertion to effect greater troop numbers. Strategically, Washington's victories at Trenton and Princeton were pivotal; they revived Patriot morale and quashed the British strategy of showing overwhelming force followed by offering generous terms, changing the course of the war. In February 1777, word of the American victories reached London, and the British realized the Patriots were in a position to demand unconditional independence.
