The following day we marched upon Williamsport, which place we reached about dark and went into camp just opposite the town. On the 17th we crossed the river and encamped on the Sharpsburg road. On the 19th we marched upon Hagerstown and remained in camp there until 22d, when we marched upon Greencastle, Pennsylvania, and camped a little south of the town and remained until the 24th, when we marched upon Chambersburg, reaching that place about the middle of the day.

Here I ascertained that General Iverson had changed his direction and was engaging the enemy, strongly posted in some woods in his front, and also that the enemy was threatening his right.
This change of General Iverson caused me to execute a corresponding change to the left. In order to support his right, my entire line, except the Second battalion and Forty-fifth regiment, was moved some distance by the left flank. I immediately moved the
