Diary of Corporal John W. Dennett, June 17, 1863

Reveille was sounded at one A.M. Marched till half-past four, to Centreville, where we saw the Ninth Massachusetts Battery. Went into camp at three P.M., at a place called Gum Springs. The day was very hot, and the roads dusty, and several of the men were sun-struck. Eighteen miles.
