General Howe’s campaign against New York brought to light another American weakness—the lack of military experience. Washington, expecting Howe to attack New York, had moved south to meet the threat immediately after Howe had abandoned Boston. But both he and his men failed badly in this first major test. Late in August Howe crossed from Staten Island to Brooklyn. In the Battle of Long Island he easily outflanked and defeated Washington’s army. Had he acted decisively, he could probably have ended the war on the spot, but Howe could not make up his mind whether to be a peacemaker or a conqueror.
This hesitation in consolidating his gains permitted Washington to withdraw his troops to Manhattan Island.
Howe could still have trapped Washington simply by using his fleet to land troops on the northern end of Manhattan; instead he attacked New York City directly, leaving the Americans an escape route to the North. Again Patriot troops proved no match for British regulars. Although Washington threw his hat to the ground in a rage and threatened to shoot cowardly Connecticut soldiers as they fled the battlefield, he could not stop the rout and had to fall back on Harlem Heights in upper Manhattan. Yet once more Howe failed to pursue his advantage promptly.
The British Take New York City
New York and New Jersey Campaigns, 1776-1777 In the summer of 1776, after abandoning Boston, several British fleets converged on New York City. After taking Staten Island, the British crossed to Brooklyn, and won a string of decisive battles in the New York region. Washington's troops retreated through New Jersey nearly to Newtown, Pennsylvania. But in the final week of 1776, Washington recrossed the Delaware River and won moraleboosting battles at Trenton and Princeton.
Still, Washington refused to see the peril in remaining on an island while the enemy commanded the surrounding waters. Only when Howe shifted a powerful force to Westchester, directly threatening his rear, did Washington move north to the mainland. Finally, after several narrow escapes, he crossed the Hudson River and marched south to New Jersey, where the British could not use their naval superiority against him.
The battles in and around New York City seemed to presage an easy British triumph. Yet somehow
Washington salvaged a moral victory from these ignominious defeats. He learned rapidly; seldom thereafter did he place his troops in such vulnerable positions. And his men, in spite of repeated failure, had become an army. In November and December 1776 they retreated across New Jersey and into Pennsylvania. General Howe then abandoned the campaign, going into winter quarters in New York but posting garrisons at Trenton, Princeton, and other strategic points.
William Mercer, painter of The Battle of Princeton (1786-1790), was deaf and mute. Charles Wilson Peale, perhaps the foremost painter of the day, took Mercer on as a student in part to see if Mercer could learn the craft.
The troops at Trenton were hated Hessian mercenaries, and Washington decided to attack them. He crossed the ice-clogged Delaware River with 2,400 men on Christmas night during a wild storm. The little army then marched nine miles to Trenton, arriving at daybreak in the midst of a sleet storm. The Hessians were taken completely by surprise. Those who could fled in disorder; the rest—900 of them—surrendered.
The Hessians were first-class professional soldiers, probably the most competent troops in Europe at that time. The victory gave a boost to American morale. A few days later Washington outmaneuvered General Cornwallis, who had rushed to Trenton with reinforcements, and won another battle at Princeton. These engagements had little strategic importance, since both armies then went into winter quarters. Without them, however, there might not have been an army to resume the war in the spring.
