One division of the British army, commanded by Sir William Howe in person, had taken post at Elkton, with its van advanced to Gray's Hill. General Knyphausen, with a second division, had crossed the ferry and encamped at Cecil Court House. He was directed to march up on the eastern side of the river, and to join Sir William Howe seven or eight miles south of Christiana. The intention to make this movement being disclosed by the preparatory arrangements, General Washington advised Maxwell to post a choice body of men in the night on an advantageous part of the road, in order to annoy him on his march. In the morning of the third of September, the two divisions under Lord Cornwallis and General Knyphausen, moved forward and formed a junction at Pencader, or Atkins' tavern, where they encamped. In their way, the column led by Lord Cornwallis fell in with and attacked Maxwell, who retreated over White Clay creek, with the loss of about forty killed and wounded.

September 5.

The whole American army, except the light infantry, took a position behind Red Clay creek, on the road leading from the camp of Sir William Howe to Philadelphia. On this ground, the General thought it probable that the fate of Philadelphia, and of the campaign, might be decided; and he resorted to all the means in his power to encourage his troops, and stimulate them to the greatest exertions.

September 8.

On the 8th of September, the British army was again put in motion. The main body advanced by Newark, upon the right of the Americans, and encamped within four miles of that place, extending its left still farther up the country. Meanwhile, a strong column made a show of attacking in front, and, after manoeuvring some time, halted at Milton, within two miles of the centre.

September 9.

General Washington was soon convinced that the column in front was designed only to amuse, while the left should effect the principal and real object. Believing that object to be to turn his right, and cut off his communication with Philadelphia, he changed his ground, and, crossing the Brandywine early in the night, took post behind that river, at Chadd's Ford. General Maxwell was advanced in front, and placed, advantageously, on the hills south of the river, on the road leading over the ford. The militia, under General Armstrong, were posted at a ford two miles below Chadd's; and the right extended some miles above, with a view to other passes deemed less practicable. In this position, General Washington attended the movements of the adverse army.

In the evening, Howe marched forward in two columns, which united, early the next morning, at Kennet's Square; after which he advanced parties on the roads leading to Lancaster, to Chadd's Ford, and to Wilmington.

The armies were now within seven miles of each other, with only the Brandywine between them, which opposed no obstacle to a general engagement. This was sought by Howe, and not avoided by Washington. It was impossible to protect Philadelphia without a victory, and this object was deemed throughout America, and especially by congress, of such magnitude as to require that an action should be hazarded for its attainment.

In the morning of the 11th, soon after day, information was received that the whole British army was in motion, advancing on the direct road leading over Chadd's Ford. The Americans were immediately under arms, and placed in order of battle, for the purpose of contesting the passage of the river. Skirmishing soon commenced between the advanced parties; and, by ten, Maxwell's corps, with little loss on either side, was driven over the Brandywine below the ford. Knyphausen, who commanded this column, paraded on the heights, reconnoitred the American army, and appeared to be making dispositions to force the passage of the river. A skirt of woods, with the river, divided him from Maxwell's corps, small parties of whom occasionally crossed over, and kept up a scattering fire, by which not much execution was done. At length one of these parties, led by Captains Waggoner and Porterfield, engaged the British flank guard very closely, killed a captain with ten or fifteen privates, drove them out of the wood, and were on the point of taking a field piece. The sharpness of the skirmish soon drew a large body of the British to that quarter, and the Americans were again driven over the Brandywine.[62]
