This statement is certainly correct.] [Sidenote: May 20.] On the night of the 19th of May, General Grant with five thousand select troops, took the road which leads up the Delaware, and consequently diverges from Barren Hill.

After marching some distance, he inclined to the left, and passing White Marsh, where several roads unite, took one leading to Plymouth meeting-house, the position he was directed to occupy, something more than a mile in the rear of the Marquis, between him and Valley Forge.

He reached his point of destination rather before sunrise.

Here the roads fork; the one leading to the camp of Lafayette, and the other to Matron's ford over the Schuylkill.
In the course of the night, General Gray, with a strong detachment, had advanced up the Schuylkill on its south side, along the ridge road, and taken post at a ford two or three miles in front of the right flank of Lafayette, while the residue of the army encamped on Chestnut hill.
Captain M'Clane, a vigilant partisan of great merit, was posted on the lines some distance in front of Barren Hill.

In the course of the night, he fell in with two British grenadiers at Three Mile Run, who informed him of the movement made by Grant, and also that a large body of Germans was getting ready to march up the Schuylkill.
