to decamping from Manhattan Island, Washington formed four divisions of the army, which were respectively assigned to Generals Lee, Heath, Sullivan (recently obtained in exchange for General Prescott), and Lincoln. Lee was stationed on Valentine's Hill, on the mainland immediately opposite King's Bridge, to cover the transportation across it of the military stores and heavy baggage. The other divisions were to form a chain of fortified posts, extending about thirteen miles along a ridge of hills on the west side of the Bronx, from Lee's camp up to the village of White Plains.
Washington's head-quarters continued to be on Harlem Heights for several days. By his skilful disposition of the army it was protected in its whole length by the Bronx, a narrow but deep stream, fringed with trees, which ran along the foot of the ridge; at the same time his troops faced and outflanked the enemy, and covered the roads along which the stores and baggage had to be transported. On the 21st, he shifted his head-quarters to Valentine's Hill, and on the 23d to White Plains, where he stationed himself in a fortified camp.
While he was thus incessantly in action, General, now Sir William Howe, remained for six days passive in his camp on Throg's Point, awaiting the arrival of supplies and reinforcements, instead of pushing across to the Hudson, and throwing himself between Washington's army and the upper country. His inaction lost him a golden opportunity. By the time his supplies arrived, the Americans had broken up the causeway leading to the mainland, and taken positions too strong to be easily forced. Finding himself headed in this direction, Sir William re-embarked part of his troops in flat boats on the 18th, crossed Eastchester Bay, and landed on Pell's Point, at the mouth of Hutchinson's River. Here he was joined in a few hours by the main body, with the baggage and artillery, and proceeded through the manor of Pelham towards New Rochelle; still with a view to get above Washington's army.
In their march, the British were waylaid and harassed by Colonel Glover of Massachusetts, with his own, Reed's and Shepard's regiments of infantry. Twice the British advance guard were thrown into confusion and driven back with severe loss, by a sharp fire from behind stone fences. A third time they advanced in solid columns. The Americans gave them repeated volleys, and then retreated with the loss of eight killed and thirteen wounded, among whom was Colonel Shepard.
On the 21st, General Howe was encamped about two miles north of New Rochelle, with his outposts extending to Mamaroneck on the Sound. While in this neighborhood, he was reinforced by a second division of Hessians under General Knyphausen, and a regiment of Waldeckers, both of which had recently arrived in New York. He was joined, also, by the whole of the seventeenth light-dragoons, and a part of the sixteenth, which had arrived on the 3d instant from Ireland, with Lieutenant-colonel (afterwards Earl) Harcourt. Some of their horses had been brought with them across the sea, others had been procured since their arrival.
The Americans at first regarded these troopers with great dread. Washington, therefore, took pains to convince them, that in a rough, broken country, like the present, full of stone fences, no troops were so inefficient as cavalry. They could be waylaid and picked off by sharp-shooters from behind walls and thickets, while they could not leave the road to pursue their covert foe. Further to inspirit them against this new enemy, he proclaimed, in general orders, a reward of one hundred dollars for every trooper brought in with his horse and accoutrements, and so on, in proportion to the completeness of the capture.
On the 25th, about two o'clock in the afternoon, intelligence was brought to head-quarters that three or four detachments of the enemy were on the march, within four miles of the camp, and the main army following in columns. The drums beat to arms; the men were ordered to their posts; an attack was expected. The day passed away, however, without any demonstration of the enemy. Howe detached none of his force on lateral expeditions, evidently meditating a general engagement. To prepare for it, Washington drew all his troops from the posts along the Bronx into the fortified camp at White Plains. Here everything remained quiet but expectant, throughout the 26th. In the morning of the 27th, which was Sunday, the heavy booming of cannon was heard from a distance seemingly in the direction of Fort Washington. Scouts galloped off to gain intelligence. We will anticipate their report.
Two of the British frigates, at seven o'clock in the morning, had moved up the Hudson, and come to anchor near Bourdett's Ferry, below the Morris House, Washington's old head-quarters, apparently with the intention of stopping the ferry, and cutting off the communication between Fort Lee and Fort Washington. At the same time, troops made their appearance on Harlem Plains, where Lord Percy held command. Colonel Morgan immediately manned the lines with troops from the garrison of Fort Washington. The ships opened a fire to enfilade and dislodge them. A barbette battery on the cliffs of the Jersey shore, left of the ferry, fired down upon the frigate, but with little effect. Colonel Magaw got down an eighteen-pounder to the lines near the Morris House, and fired fifty or sixty rounds, two balls at a time. Two eighteen-pounders were likewise brought down from Fort Lee, and planted opposite the ships. By the fire from both shores they were hulled repeatedly.
It was the thundering of these cannonades which had reached Washington's camp at White Plains. The ships soon hoisted all sail. The foremost slipped her cable, and appeared to be in the greatest confusion. She could make no way, though towed by two boats. The other ship seeing her distress sent two barges to her assistance, and by the four boats she was dragged out of reach of the American fire, her pumps going all the time. At the time that the fire from the ships began, Lord Percy brought up his field-pieces and mortars, and made an attack upon the lines. He was resolutely answered by the troops sent down from Fort Washington, and several Hessians were killed. An occasional firing was kept up until evening, when the ships fell down the river, and the troops which had advanced on Harlem Plains drew within their lines again.
While these things were passing at Fort Washington, Lee had struck his tents, and with the rear division, eight thousand strong, the baggage and artillery, and a train of wagons four miles long, laden with stores and ammunition, was lumbering along the rough country roads to join the main army. It was not until Monday morning, after being on the road all night, that he arrived at White Plains.
Washington's camp was situated on high ground, facing the east. The right wing stretched towards the south along a rocky hill, at the foot of which the Bronx, making an elbow, protected it in flank and rear. The left wing rested on a small, deep lake among the hills. The camp was strongly intrenched in front. About a quarter of a mile to the right of the camp, and separated from the height on which it stood by the Bronx and a marshy interval, was a corresponding height called Chatterton's Hill. As this partly commanded the right flank, and as the intervening bend of the Bronx was easily passable, Washington had stationed on its summit a militia regiment.
The whole encampment was a temporary one, to be changed as soon as the military stores collected there could be removed; and now that General Lee was arrived, Washington rode out with him, and other general officers who were off duty, to reconnoitre a height which appeared more eligible. When arrived at it, Lee pointed to another on the north, still more commanding. "Yonder," said he "is the ground we ought to occupy." "Let us go, then, and view it," replied Washington. They were gently riding in that direction, when a trooper came spurring up his panting horse. "The British are in the camp, sir!" cried he. "Then, gentlemen," said Washington, "we have other business to attend to than reconnoitring." Putting spurs to his horse, he set off for the camp at full gallop, the others spurring after him.
Arrived at head-quarters, he was informed by Adjutant-general Reed, that the picket guards had all been driven in, and the enemy were advancing; but that the whole American army was posted in order of battle. Apprehensive that the enemy might attempt to get possession of Chatterton's Hill, he detached Colonel Haslet with his Delaware regiment, to reinforce the militia posted there. To these he soon added General McDougall's brigade, composed of Smallwood's Marylanders, Ritzema's New Yorkers, and two other regiments. General McDougall had command of the whole force upon the hill, which did not exceed 1,600 men.
These dispositions were scarcely made, when the enemy appeared glistening on the high grounds beyond the village of White Plains. They advanced in two columns, the right commanded by Sir Henry Clinton, the left by the Hessian general, De Heister. There was also a troop of horse; so formidable in the inexperienced eyes of the Americans. For a time they halted in a wheat field, behind a rising ground, and the general officers rode up in the centre
