While Lee was thus loitering and speculating, Cornwallis, knowing how far he was in the rear, and how weak was the situation of Washington's army, and being himself strongly reinforced, made a forced march from Brunswick, and was within two miles from Princeton. Stirling, to avoid being surrounded, immediately set out with two brigades for Trenton. Washington, too, receiving intelligence by express of these movements, hastened back to that place, and caused boats to be collected from all quarters, and the stores and troops transported across the Delaware. He himself crossed with the rear-guard on Sunday morning, and took up his quarters about a mile from the river; causing the boats to be destroyed, and troops to be posted opposite the fords.
The rear-guard, says an American account, had barely crossed the river, when Lord Cornwallis "came marching down with all the pomp of war, in great expectation of getting boats, and immediately pursuing." Not one was to be had there or elsewhere; for Washington had caused the boats, for an extent of seventy miles up and down the river, to be secured on the right bank. His lordship was effectually brought to a stand. He made some moves with two columns, as if he would cross the Delaware above and below, either to push on to Philadelphia, or to entrap Washington in the acute angle made by the bend of the river opposite Bordentown. An able disposition of American troops along the upper part of the river, and of a number of galleys below, discouraged any attempt of the kind. Cornwallis, therefore, gave up the pursuit, distributed the German troops in cantonments along the left bank of the river, and stationed his main force at Brunswick, trusting to be able before long to cross the Delaware on the ice.
On the 8th, Washington wrote to the President of Congress: "There is not a moment's time to be lost in assembling such a force as can be collected, as the object of the enemy cannot now be doubted in the smallest degree. Indeed, I shall be out in my conjecture, for it is only conjecture, if the late embarkation at New York is not for Delaware River, to co-operate with the army under General Howe, who, I am informed from good authority, is with the British troops, and his whole force upon this route."
In further letters to Lee, Washington urged the peril of Philadelphia. "Do come on," writes he; "your arrival may be fortunate, and, if it can be effected without delay, it may be the means of preserving a city, whose loss must prove of the most fatal consequence to the cause of America." Putnam was now detached to take command of Philadelphia, and put it in a state of defence, and General Mifflin to have charge of the munitions of war deposited there. By their advice Congress hastily adjourned on the 12th of December, to meet again on the 20th at Baltimore.
Washington's whole force at this time was about five thousand five hundred men. Gates, however, he was informed, was coming on with seven regiments detached by Schuyler from the Northern department; reinforced by these and the troops under Lee, he hoped to be able to attempt a stroke upon the enemy's forces, which lay a good deal scattered, and to all appearances, in a state of security.
While cheering himself with these hopes, and trusting to speedy aid from Lee, that wayward commander, though nearly three weeks had elapsed since he had received Washington's orders and entreaties to join him with all possible despatch, was no farther on his march than Morristown, in the Jerseys; where with militia recruits, his force was about four thousand men. [Lee was secretly planning an independent attack on the enemy. Hearing that three regiments detached under Gates from the Northern army had arrived at Peekskill, he sent orders for them to join him at Morristown. "I am in hopes," he writes, "to reconquer the Jerseys." In the meantime Washington wrote urging his speedy junction with him. Boats were gathered at Tinicum to facilitate his passage across the Delaware. "I have so frequently," wrote Washington, "mentioned our situation and the necessity of your aid, that it is painful for me to add a word on the subject." On the 12th, Lee moved from Morristown, but marched no further than Vealtown, eight miles distant. There he left Sullivan with his troops, while he took up his quarters three miles off, at a tavern at Baskingridge. Intelligence of his exposed and insecure position reached the enemy, a body of dragoons were detached, and guided by a tory, came upon Lee in his quarters without warning. The few guards about the house were soon dispersed, and Lee, bare-headed and in his slippers, was compelled in haste to mount a horse and accompany his captors. This capture gave great exultation to the enemy; for they considered Lee the most scientific and experienced of the rebel generals. General Sullivan now being in command, immediately pressed forward with the troops to join the commander-in-chief.]
The loss of Lee was a severe shock to the Americans, many of whom, as we have shown, looked to him as the man who was to rescue them from their critical and well-nigh desperate situation. General Wilkinson, in his memoirs, [who was at that time brigade-major under General Gates,] points out what he considers the true secret of Lee's conduct. His military reputation, originally very high, had been enhanced of late by its being generally known that he had been opposed to the occupation of Fort Washington; while the fall of that fortress and other misfortunes of the campaign, though beyond the control of the commander-in-chief, had quickened the discontent which, according to Wilkinson, had been generated against him at Cambridge, and raised a party against him in Congress. "It was confidently asserted at the time," adds he, "but is not worthy of credit, that a motion had been made in that body tending to supersede him in the command of the army. In this temper of the times, if General Lee had anticipated General Washington in cutting the cordon of the enemy between New York and the Delaware, the commander-in-chief would probably have been superseded. In this case, Lee would have succeeded him."
What an unfortunate change would it have been for the country! Lee was undoubtedly a man of brilliant talents, shrewd sagacity, and much knowledge and experience in the art of war; but he was wilful and uncertain in his temper, self-indulgent in his habits, and an egoist in warfare; boldly dashing for a soldier's glory rather than warily acting for a country's good. He wanted those great moral qualities which, in addition to military capacity, inspired such universal confidence in the wisdom, rectitude and patriotism of Washington, enabling him to direct and control legislative bodies as well as armies; to harmonize the jarring passions and jealousies of a wide and imperfect confederacy, and to cope with the varied exigencies of the Revolution.
Congress, prior to their adjournment, had resolved that "until they should otherwise order, General Washington should be possessed of all power to order and direct all things relative to the department and to the operations of war." Thus empowered, he proceeded immediately to recruit three battalions of artillery. To those whose terms were expiring he promised an augmentation of twenty-five per cent. upon their pay, and a bounty of ten dollars to the men for six weeks' service. "It was no time," he said, "to stand upon expense; nor in matters of self-evident exigency to refer to Congress at the distance of a hundred and thirty or forty miles. If any good officers will offer to raise men upon continental pay and establishment in this quarter, I shall encourage them to do so, and regiment them when they have done it."
The promise of increased pay and bounties had kept together for a time the dissolving army. The local militia began to turn out freely. Colonel John Cadwalader, a gentleman of gallant spirit, and cultivated mind and manners, brought a large volunteer detachment, well equipped, and composed principally of Philadelphia troops. Washington, who held Cadwalader in high esteem, assigned him an important station at Bristol, with Colonel Reed, who was his intimate friend, as an associate. They had it in charge to keep a watchful eye upon Count Donop's Hessians, who were cantoned along the opposite shore from Bordentown to the Black Horse.
On the 20th of December arrived General Sullivan in camp, with the troops recently commanded by the unlucky Lee.
