Supposing the redoubts carried, and the British army driven into the town, yet all military men were agreed on the great peril of storming a town. The streets would be defended by an artillery greatly superior to that of the Americans, which would attack in front, while the brick houses would be lined with musketeers, whose first must thin the ranks of the assailants.
A part of the plan, on the successful execution of which the whole depended, was, that the British rear should be surprised by the corps descending the Delaware. This would require the concurrence of too many favourable circumstances to be calculated on with any confidence. As the position of General Greene was known, it could not be supposed that Sir William Howe would be inattentive to him. It was probable that not even his embarkation would be made unnoticed; but it was presuming a degree of negligence which ought not to be assumed, to suppose that he could descend the river to Philadelphia undiscovered. So soon as his movements should be observed, the whole plan would be comprehended, since it would never be conjectured that General Greene was to attack singly.
If the attack in front should fail, which was not even improbable, the total loss of the two thousand men in the rear must follow; and General Howe would maintain his superiority through the winter.
The situation of America did not require these desperate measures. The British general would be compelled to risk a battle on equal terms, or to manifest a conscious inferiority to the American army. The depreciation of paper money was the inevitable consequence of immense emissions without corresponding taxes. It was by removing the cause, not by sacrificing the army, that this evil was to be corrected.
Washington possessed too much discernment to be dazzled by the false brilliant presented by those who urged the necessity of storming Philadelphia, in order to throw lustre round his own fame, and that of his army; and too much firmness of temper, too much virtue and real patriotism, to be diverted from a purpose believed to be right, by the clamours of faction or the discontents of ignorance. Disregarding the importunities of mistaken friends, the malignant insinuations of enemies, and the expectations of the ill-informed; he persevered in his resolution to make no attempt on Philadelphia. He saved his army, and was able to keep the field in the face of his enemy; while the clamour of the moment wasted in air, and is forgotten.
The opinion that Sir William Howe meditated an attack on the American camp, was not ill founded. Scarcely had Lord Cornwallis returned to Philadelphia, and Greene to the American army, when unquestionable intelligence was received that the British general was preparing to march out in full strength, with the avowed object of forcing Washington from his position, and driving him beyond the mountains.
General Howe marches out to Chestnut Hill.
On the 4th of December, Captain M'Lane, a vigilant officer on the lines, discovered that an attempt to surprise the American camp at White Marsh was about to be made, and communicated the information to the Commander-in-chief. In the evening of the same day, General Howe marched out of Philadelphia with his whole force; and, about eleven at night, M'Lane, who had been detached with one hundred chosen men, attacked the British van at the Three Mile Run, on the Germantown road, and compelled their front division to change its line of march. He hovered on the front and flank of the advancing army, galling them severely until three next morning, when the British encamped on Chestnut Hill, in front of the American right, and distant from it about three miles. A slight skirmish had also taken place between the Pennsylvania militia under General Irvine, and the advanced light parties of the enemy, in which the general was wounded, and the militia, without much other loss, were dispersed.
The range of hills on which the British were posted, approached nearer to those occupied by the Americans, as they stretched northward.
Having passed the day in reconnoitring the right, Sir William Howe changed his ground in the course of the night, and moving along the hills to his right, took an advantageous position, about a mile in front of the American left. The next day he inclined still farther to his right, and, in doing so, approached still nearer to the left wing of the American army. Supposing a general engagement to be approaching, Washington detached Gist with some Maryland militia, and Morgan with his rifle corps, to attack the flanking and advanced parties of the enemy. A sharp action ensued, in which Major Morris, of Jersey, a brave officer in Morgan's regiment, was mortally wounded, and twenty-seven of his men were killed and wounded. A small loss was also sustained in the militia. The parties first attacked were driven in; but the enemy reinforcing in numbers, and Washington, unwilling to move from the heights, and engage on the ground which was the scene of the skirmish, declining to reinforce Gist and Morgan, they, in turn, were compelled to retreat.
