The Federal forces in that vicinity were then posted as follows:—General Stone, with General Gorman’s brigade, Seventh Michigan, two troops of Van Alen cavalry, and the Putnam Rangers, at Edwards Ferry; five companies of Massachusetts Volunteers, under Colonel Devens, at Harrison’s Island; and Colonel Lee, with a battalion of the Massachusetts Twentieth, a section of the Rhode Island battery, and the Tammany regiment, were sent to Conrad’s Ferry. A section of Bunting’s New York battery was planted at Edwards and a section of Rickett’s battery at Conrad’s Ferry. When the report of the scouts was received, orders were sent to Colonel Devens to march four companies to the Virginia shore, from Harrison’s Island, and under cover of the night, take up a position near the camp referred to, and attack it at daybreak, drive out the enemy, pursue them as far as prudent, and return to the island. Orders were also sent to Colonel Baker, to march the First California regiment to Conrad’s Ferry, to arrive there at sunrise, and to have the remainder of his brigade ready to move at an early hour. Lieutenant-Colonel Wood, of the Fifteenth Massachusetts, was also ordered to move with a battalion to the river bank opposite Harrison’s Island by daybreak. Two mounted howitzers in charge of Lieutenant Trench, of Rickett’s battery, were ordered to the tow-path of the canal opposite Harrison’s Island. This disposition of the troops having been made for the commencement of the movement, it was necessary to provide the means for their transportation across the river, which is quite rapid at this point. Edwards Ferry is below the island, which is about three miles in length, and Conrad’s Ferry is a short distance beyond the upper end. The island lies about a third of the distance from the Virginia shore, while a swift current of three hundred yards separates it from the Maryland banks, traversed by a tow-path of the Chesapeake and Ohio canal. The Virginia bank opposite the island is steep, and is backed by a precipitous bluff, varying in height from eighty to one hundred and fifty feet, covered with brush, trees and undergrowth. There was no adequate preparation to effect the passage of troops at these points. The means were scanty either for reinforcement, or for retreat, if that should become necessary. On the Maryland side of Harrison’s Island were two scows, capable of carrying thirty persons each, which could make two trips hourly, thus conveying one hundred and twenty men. On the Virginia side was one scow and a small boat. At Edwards Ferry there were two scows and a ship’s yawl. With these insufficient means of transportation an attempt was made to land the forces on the opposite shore. The landings at both of the ferries are good, but stretching almost the entire distance between them is the high and steep bank known as Ball’s Bluff, where the crossing was attempted, and which has given its name to this bloody struggle.
