[Footnote 2: General Wilkinson, in his memoirs, says that this notice
was given by a person formerly a lieutenant in Proctor's regiment of
artillery, who, disgusted at being discarded from the American
service, became a spy to Sir William Howe; and, the better to fulfil
his new engagements, kept up his acquaintance with his former
comrades, and frequently visited the camp at Valley Forge. To avoid
the suspicion which would be excited by his going into Philadelphia, a
rendezvous had been established on Frankford Creek, where he met a
messenger from General Howe, to whom his communications were
delivered. 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.
