Some mentions of Centreville during the Gettysburg campaign:
-26 June [1863], they are firing [burning] the buildings that contain Government stores. The large church must go too, it's a pity to see it burning as it is a fine building and has a very fine organ. But it's full of hard bread and hay, so it must go. Such is war! (Diary of Major John I. Nevin, 93 PA -'On the March Again at Daybreak,' ed. by Dana B. Shoaf, A Journal of the American Civil War, vol. 6, no. 3 (Savas Publishing Company), p. 118)
-The most forsaken looking place I ever saw [25 June]. The 111th New York took down their "A" and wall tents and they, with many other stores, were stored in the church. ... On 26 June the church containing the stores of the brigade that left here yesterday was in flames. Many of the government stores shared the same fate. (Diary of Alonzo Clapp, 122nd New York)
-Only a few buildings now standing [as of 25 June], and they are mere huts built of logs. Every hill is crowned with a fort, and they are all connected by rifle pits and covered ways for artillery to pass from one to another. (Elisha Hunt Rhodes, All for the Union (2nd Rhode Island), pp. 113-114)
-[Mid-June] Halt made at Centreville for two days, and no one who was on that march will ever forget the great spring of clear cold water, gushing out of the ground in a stream as large as a stove pipe, at the very top of the hill. There was water enough for all and to spare. (Lt. Francis Wiggin, 16th Maine)
-Quite a village, the buildings of which, made of stone, have a venerable and ancient appearance. A fine stream nearby was convenient for bathing and washing. (22 June letter of Lt. Rush P. Cady, 97th New York)
