On receiving this intelligence, he crossed the Delaware, and posted his army in such a manner as to guard the fords. As his rear passed the river, the van of the British army appeared in sight. The main body took post at Trenton, and detachments were placed both above and below, while small parties, without interruption from the people of the country, reconnoitred the Delaware for a considerable distance. Danger of Philadelphia.From Bordentown below Trenton the course of the river turns westward, and forms an acute angle with its course from Philadelphia to that place; so that Lord Cornwallis might cross a considerable distance above, and be not much, if any, farther from that city than the American army.

The British general made some unsuccessful attempts to seize a number of boats guarded by Lord Stirling, about Coryell's Ferry; and, in order to facilitate his movements down the river, on the Jersey shore, repaired the bridges below Trenton, which had been broken down by order of General Washington. He then advanced a strong detachment to Bordentown, giving indications of an intention to cross the Delaware at the same time above and below; and either to march in two columns to Philadelphia, or completely to envelop the American army in the angle of the river. To counteract this plan, the American General stationed a few gallies to watch the movements of his enemy below, and aid in repelling any effort to pass over to the Pennsylvania shore; and made such a disposition of his little army as to guard against any attempt to force a passage above, which he believed to be the real design.

Having made his arrangements, he waited anxiously for reinforcements; and, in the meantime, sent daily parties over the river to harass the enemy, and to observe his situation.

The utmost exertions were made by government to raise the militia. In the hope that a respectable body of continental troops would aid these exertions, General Washington had directed General Gates, with the regulars of the northern army, and General Heath, with those at Peekskill, to march to his assistance.

Capture of General Lee.

Although General Lee had been repeatedly urged to join the Commander-in-chief, he proceeded slowly in the execution of these orders, manifesting a strong disposition to retain his separate command, and rather to hang on, and threaten the rear of the British army, than to strengthen that in its front. With this view he proposed establishing himself at Morristown. On receiving a letter from General Washington disapproving this proposition, and urging him to hasten his march, Lee still avowed a preference for his own plan, and proceeded reluctantly towards the Delaware. While passing through Morris county, at the distance of twenty miles from the British encampment, he, very incautiously, quartered under a slight guard, in a house about three miles from his army. Information of this circumstance was given by a countryman to Colonel Harcourt, at that time detached with a body of cavalry to watch his movements, who immediately formed and executed the design of seizing him. Early in the morning of the 12th of December, this officer reached Lee's quarters, who received no intimation of his danger until the house was surrounded, and he found himself a prisoner. He was carried off in triumph to the British army, where he was, for some time, treated as a deserter from the British service.

This misfortune made a serious impression on all America. The confidence originally placed in General Lee had been increased by his success in the southern department, and by a belief that his opinions, during the military operations in New York, had contributed to the adoption of those judicious movements which had, in some measure, defeated the plans of General Howe in that quarter. It was also believed that he had dissented from the resolution of the council of war for maintaining forts Washington and Lee. No officer, except the Commander-in-chief, possessed, at that time, in so eminent a degree, the confidence of the army, or of the country; and his loss was, almost universally, bewailed as one of the greatest calamities which had befallen the American arms. It was regretted by no person more than by General Washington himself. He respected the merit of that eccentric veteran, and sincerely lamented his captivity.

General Sullivan, on whom the command of that division devolved after the capture of Lee, promptly obeyed the orders which had been directed to that officer; and, crossing the Delaware at Philipsburg, joined the Commander-in-chief. On the same day General Gates arrived with a few northern troops. By these and other reinforcements, the army was augmented to about seven thousand effective men.

The British go into winter quarters.

The attempts of the British general to get possession of boats for the transportation of his army over the Delaware having failed, he gave indications of an intention to close the campaign, and to retire into winter quarters. About four thousand men were cantoned on the Delaware at Trenton, Bordentown, the White Horse, and Mount Holly; and the remaining part of the army of Jersey was distributed from that river to the Hackensack. Strong corps were posted at Princeton, Brunswick, and Elizabethtown.
