"Camp Slifer, Chambersburg, 9 May, 1861 - Directly eastward from the city, and three-quarters of a mile distant, partially upon the summit of a knoll, is Camp Slifer, so called in honour of the worthy Secretary of State, who, throughout the varied duties of his position, has never neglected the soldier enlisted in the cause of his country."

Philadelphia Inquirer, 11 May, 1861 - Camp Slifer, at Chambersburg

"Chambersburg, 8 June - The Seventh Pennsylvania, Col. Irwin; Eighth, Col. Emley; Tenth, Col. Meredith, and Twentieth, Col. Gray, constituting the Second Brigade, under command of General Williams, moved hence this morning, and will halt three miles this side of Greencastle."

World (New York City, New York County, New York), 10 June, 1861 - From Chambersburg

"Chambersburg, Pa., 10 June - About four miles south of this borough, and on the direct road down the fertile Cumberland valley, which leads you to Hagerstown, lies a camp I have not yet described, Camp Chambers. It is in reality four camps, located apparently upon as many farms, the farthest asunder being nearly a mile apart."

World (New York City, New York County, New York), 12 June, 1861 - From Chambersburg

"Camp Meredith, near Greencastle, 10th June, 1861 - On Wednesday, the 29th of May, we received marching orders; but for some inexplicable cause the orders were countermanded, and the time of our moving postponed until Thursday, the 30th."

"We arrived at the depot at about 11 A. M., and took our seats in the cars and moved off amidst cheers and firing of cannon."

"We arrived at Harrisburg at dusk, where we remained a few minutes, and again proceeded on our route to Chambersburg."

"We arrived at Chambersburg at about 11 o’clock, and slept in the cars all night. At daylight the column was formed, and we marched up to the city, stacked arms in the main street, and awaited the coming of our baggage and tents."

"At 11 A. M., our baggage and tents arrived, and we took up our line of march for Camp Chambers, distant about four miles, where we arrived about 1 P. M. The camp was situated in an open clover field, with woods to the north of us, and a branch of the Potomac to the west, which has given us the advantage of shade and water close at hand."

"Our camp lies about three-quarters of a mile north of Greencastle, on a gentle rise, with a fine view of the country. To the northward of us lie the Eighth and Tenth Regiments, and east of us the Seventh, the four regiments forming Gen. Williams’ Brigade."

Philadelphia Inquirer, 15 June, 1861 - Letter from the Scott Legion

"We left Camp Chambers on Saturday, the 8th, at about 3 P. M., and arrived at Camp Meredith at 7."

"We remained at Camp Meredith until the 15th enjoying ourselves hugely, notwithstanding the excessively hot weather. The Seventh, Eighth, and Tenth Regiments, who form the rest of General Williams’ Brigade, were encamped in the adjoining fields."

"On Friday afternoon, the 14th, we received marching orders, and at 2 A. M., Saturday, we were up, struck our tents, packed our knapsacks, and were ready for marching in a short time. We moved off at about 6 o’clock, in the direction of Hagerstown."

"We arrived at Hagerstown at 2 P. M., and after a short halt marched in the direction of Williamsport, and arrived at our camp ground, near Middleburg, about nine o’clock, after a fatiguing march of about twenty-two miles."

"About noon on Sunday a messenger came riding in hot haste, saying that 6000 Secessionists were marching on Williamsport, and with orders for us to go on and defend the place."

"We arrived at Williamsport about 4 P. M. only to find that it was a false alarm, and not a Secessionist in sight. We encamped in a field about half a mile east of the town of Williamsport and from the Potomac river, where we are at present writing, awaiting further orders."

Philadelphia Inquirer, 22 June, 1861 - Our Williamsport correspondence

"General Patterson and staff left here this afternoon for Downsville, and it is generally understood that the whole force will cross the river at three points simultaneously tomorrow morning at three o’clock. The points and brigades will be: Fourth Brigade, General Williams, Seventh, Eighth, Tenth and Twentieth Regiments; Fifth Brigade, Colonel Longnecker, Ninth, Thirteenth and Sixteenth Regiments - cross at Williamsport. First Brigade, Colonel C. P. dare, commanding, viz.: Colonel Thomas’ regular cavalry, the Philadelphia City Troop, the Sixth, Twenty-first and Twenty-third Regiments - at Falling Waters. The Wisconsin Regiment and Eleventh Pennsylvania Regiment, with Perkins’ Battery will likely cross at the same place. The Second Brigade, General Wynkoop, viz.: First, Second, Third, Fourteenth and Fifteenth Regiments, will cross at Shepherdstown."
