Friday, May 27. — Held the ford until half-past eight A.M., when we were relieved by the cavalry. We then marched down towards Bethel Church. During the day our corps formed the rear guard, marching after the trains. We marched until about 10 P.M., making about 10 or 11 miles, one of the most fatiguing marches I have ever made. We had to halt every few feet. Went into camp just after striking the Bowling Green Road. Ten stragglers.
