We moved at a sufficient distance from the Rappahannock to screen our columns from the enemy's posts of observation. We marched to the vicinity of Elkton, where we bivouacked for the night. The next morning we resumed our march, and soon struck the railroad at Bealeton, where we met and drove a detachment of Rebel cavalry. After a sharp skirmish they fell back to Beverly Ford, where their crossing was covered by artillery and sharpshooters. A neat little fight enabled us to advance carbineers down to the ford, which we held, though subjected to the fire of rifled cannon on the opposite bank. At another of the numerous fords of the river (Sulphur Springs), which was not guarded, an entire division was forded across before night. But during the night a heavy rain-storm set in _a la Virginie_, which so suddenly raised the stream, that the order for crossing more troops was not only countermanded, but the forces already across were ordered to return. This was not very easily done. Meanwhile the separated division, by rapid movement and some fighting through the rain, had swung down the river to Beverly Ford, where they commenced recrossing, without pontoons, and with the ford unfordable. The enemy, taking advantage of this unhappy predicament, attacked the rearguard with furious determination, killing and capturing quite a number. As our artillery could not be brought into position, the only help we could afford to our unfortunate comrades was to play on the Rebels with our carbines, which kept them somewhat at bay. In the haste and difficulty of crossing, where horses were compelled to swim a considerable distance through the strong current, several animals and men were drowned and borne down the stream. It was certainly a very sad experience--a disheartening commencement of operations. _April 16._--The Harris Light was relieved from picket, and moved to Bealeton, leaving Beverly Ford at four o'clock A. M. The roads are almost impassable. The rain has continued almost uninterruptedly for forty-eight hours, making our sojourn in these parts very disagreeable. But, notwithstanding the mud, on the seventeenth a squadron of the Harris Light, composed of Companies E and F, in command of Captain Charles Hasty, left our bivouac at Bealeton, early in the morning, with instructions to proceed to Warrenton, and, if possible, to occupy the place until four o'clock P. M. When we had approached to within three miles of the place the Captain learned that the famous Black Horse Cavalry, under Captain Randolph, was in possession of the village, and would undoubtedly give us a splendid entertainment.
