June 26th. Rained nearly all last night, and in consequence the roads are very bad. To-day at 6 A. M. marched to Edward’s Ferry on the Potomac, reaching there at midnight. The march was excessively fatiguing, as we were eighteen hours on the road, the latter part of which was execrable. Crossing the river immediately upon our arrival, we formed in close column of division, stacked arms, and lay down to sleep, the men badly used up, many of them missing. There was much confusion here, caused by the immense trains, which occupied the roads to the exclusion of the troops. Many of the wagons were disabled, and the road was constantly blockaded. We heard on our arrival that Lee had crossed the Potomac and was heading directly for Pennsylvania.
