The Battle of Trenton was a small but pivotal American Revolutionary War battle on the morning of December 26, 1776, in Trenton, New Jersey. After General George Washington's crossing of the Delaware River north of Trenton the previous night, Washington led the main body of the Continental Army against Hessian auxiliaries garrisoned at Trenton. After a brief battle, almost two-thirds of the Hessian force were captured, with negligible losses to the Americans. The battle significantly boosted the Continental Army's waning morale, and inspired re-enlistments.
The Continental Army had previously suffered several defeats in New York and had been forced to retreat through New Jersey to Pennsylvania. Morale in the army was low; to end the year on a positive note, George Washington, Commander-in-Chief of the Continental Army, devised a plan to cross the Delaware River on the night of December 25–26 (Christmas and St. Stephen's Day)[6] and surround the Hessians' garrison.
Because the river was icy and the weather severe, the crossing proved dangerous. Two detachments were unable to cross the river, leaving Washington with only 2,400 men under his command in the assault, 3,000 fewer than planned. The army marched 9 mi (14.5 km) south to Trenton. The Hessians had lowered their guard, thinking they were safe from the Americans' army, and had no long-distance outposts or patrols. Washington's forces caught them off guard, and after a short but fierce resistance, most of the Hessians surrendered and were captured, with just over a third escaping across Assunpink Creek.
Despite the battle's small numbers, the victory inspired patriots and sympathizers of the newly formed United States. With the success of the ongoing revolution in doubt a week earlier, the army had seemed on the verge of collapse. The dramatic victory inspired soldiers to believe the war was not a lost cause, serve longer and attracted new recruits to the ranks.[6]
In early December 1776, American morale was very low.[7] The Americans had been ousted from New York by the British and their Hessian auxiliaries, and the Continental Army was forced to retreat across New Jersey. Ninety percent of the Continental Army soldiers who had served at Long Island were gone.[8] Men had deserted, feeling that the cause for independence was lost. Washington, Commander-in-Chief of the Continental Army, expressed some doubts, writing to his cousin in Virginia, "I think the game is pretty near up."[9]
At the time a small town in New Jersey, Trenton was occupied by four regiments of Hessian soldiers (numbering about 1,400 men) commanded by Colonel Johann Rall. Washington's force comprised 2,400 men, with infantry divisions commanded by Major Generals Nathanael Greene and John Sullivan, and artillery under the direction of Brigadier General Henry Knox.[10]
George Washington had stationed a spy named John Honeyman, posing as a Tory, in Trenton. Honeyman had served with Major General James Wolfe in Quebec at the Battle of the Plains of Abraham on September 13, 1759, and had no trouble establishing his credentials as a Tory. Honeyman was a butcher and bartender, who traded with the British and Hessians. This enabled him to gather intelligence and to convince the Hessians that the Continental Army was in such a low state of morale that they would not attack Trenton. Shortly before Christmas, he arranged to be captured by the Continental Army, who had orders to bring him to Washington unharmed. After being questioned by Washington, he was imprisoned in a hut to be tried as a Tory in the morning, but a small fire broke out nearby, enabling him to "escape".[11] On the evening before the battle, Hessian commander Rall was celebrating Christmas with his troops at the farm of Abraham Hunt, a wealthy merchant and farmer of Trenton. Hunt played the role of a friendly Loyalist host, giving Rall a false sense of serenity while Washington and his troops were preparing for a surprise attack.[12]
The U.S. plan relied on launching coordinated attacks from three directions. General John Cadwalader would launch a diversionary attack against the British garrison at Bordentown, New Jersey, to block off reinforcements from the south. General James Ewing would take 700 militia across the river at Trenton Ferry, seize the bridge over the Assunpink Creek and prevent enemy troops from escaping. The main assault force of 2,400 men would cross the river 9 mi (14 km) north of Trenton and split into two groups, one under Greene and one under Sullivan, to launch a pre-dawn attack.[13] Sullivan would attack the town from the south, and Greene from the north.[8] Depending on the success of the operation, the Americans would possibly follow up with separate attacks on Princeton and New Brunswick.[7]
During the week before the battle, U.S. advance parties began to ambush enemy cavalry patrols, capturing dispatch riders and attacking Hessian pickets. The Hessian commander, to emphasize the danger his men were facing, sent 100 infantry and an artillery detachment to deliver a letter to the British commander at Princeton.[7] Washington ordered Ewing and his Pennsylvania militia to try to gain information on Hessian movements and technology.[14] Ewing instead made three successful raids across the river. On December 17 and 18, 1776, they attacked an outpost of jägers and on the 21st, they set fire to several houses.[14] Washington put constant watches on all possible crossings near the Continental Army encampment on the Delaware, as he believed William Howe would launch an attack from the north on Philadelphia if the river froze over.[15]
On December 20, 1776, some 2,000 troops led by General Sullivan arrived in Washington's camp.[16] They had been under the command of Charles Lee and had been moving slowly through northern New Jersey when Lee was captured. That same day, an additional 800 troops arrived from Fort Ticonderoga under the command of Horatio Gates.[16]
On December 14, 1776, the Hessians arrived in Trenton to establish their winter quarters.[17] At the time, Trenton was a small town with about 100 houses and two main streets, King (now Warren) Street and Queen (now Broad) Street.[18] Carl von Donop, Rall's superior, had marched south to Mount Holly on December 22 to deal with the resistance in New Jersey, and had clashed with some New Jersey militia there on December 23.[19]
Donop, who despised Rall, was reluctant to give command of Trenton to him.[20] Rall was known to be loud and unacquainted with the English language,[20] but he was also a 36-year veteran with a great deal of battle experience. His request for reinforcements had been turned down by British commander General James Grant, who disdained the American rebels and thought them poor soldiers. Despite Rall's experience, the Hessians at Trenton did not admire their commander.[21]
Trenton lacked city walls or fortifications, which was typical of U.S. settlements.[22] Some Hessian officers advised Rall to fortify the town, and two of his engineers advised that a redoubt be constructed at the upper end of town and fortifications be built along the river.[22] The engineers went so far as to draw up plans, but Rall disagreed with them.[22] When Rall was again urged to fortify the town, he replied, "Let them come ... We will go at them with the bayonet."[22]
As Christmas approached, Loyalists came to Trenton to report the Americans were planning action.[9] U.S. deserters told the Hessians that rations were being prepared for an advance across the river. Rall publicly dismissed such talk as nonsense, but privately in letters to his superiors, he said he was worried about an imminent attack.[9] He wrote to Donop that he was "liable to be attacked at any moment". Rall said that Trenton was "indefensible" and asked that British troops establish a garrison in Maidenhead (now Lawrenceville). Close to Trenton, this would help defend the roads from Americans. His request was denied.[23] As the Americans disrupted Hessian supply lines, the officers started to share Rall's fears. One wrote, "We have not slept one night in peace since we came to this place."[24] On December 22, 1776, a spy reported to Grant that Washington had called a council of war; Grant told Rall to "be on your guard".[25]
The main Hessian force of 1,500 men was divided into three regiments: Knyphausen, Lossberg and Rall. That night, they did not send out any patrols because of the severe weather.[26]
