Looking at the pace, progress of the crossings at Edwards Ferry, the flow of troops on June 25, 1863 was not sufficient given the critical operational situation. The three corps which crossed that day – the Eleventh, First, and Third, in that order generally – did so with delayed progress. Not only delays as the engineers placed a second bridge, but the units making the crossing brought their own delays… not the least of which were the additional horses brought by the Eleventh Corps. And we see the rains, which were recorded by Captain William Folwell’s letter of the day, which caused the Third Corps much misery as the crossing and march into Maryland continued into the early morning hours.
By contrast, June 26 was a flood of men and equipment. Although on paper, again only three corps crossed – the Twelfth, Fifth, and Second, in that order. Add to that movement the Artillery Reserve, Army Headquarters element, and the majority of six corps worth of wagon trains. The march must have seemed endless to any eyewitness. And Folwell was just such an eyewitness. Just after noon on June 26, he resumed writing a letter home, this being a post-script to a letter written the previous evening:
P.S. June 26th, 1863, 1 P.M.
The letter I wrote last evening must lie over till tomorrow as we can only send and receive a mail on alternate days. We get our mail at present by the little steamer packet which runs on the canal from Georgetown to this place. To-day we have a fine misty rain, falling steadily, which keeps all of us not on duty under cover. I have written you a short letter and would have done you a long one if the Major ([E.O.] Beers) and some of the other officers had not come in and spent a large part of the forenoon with me. The 12th Corps had crossed this morning and the troops of another, (I think the 2nd) have just appeared on the opposite hills. Gen. Hooker and staff came over just before noon and followed the advance of the Army. We have yet no information as to the destination of the forces. Gen. Hooker seemed anxious to have the wagon trains hurried up and commended on of our officers (Capt. [Martin] Van Brocklin) whom he saw moving them on. I have not been out of camp to-day. It is an old story to see the Army cross, for me. Bain [Lieutenant Mahlon Bainbridge Folwell] is well and full of business as both adjutant and Quartermaster of detachment. I hope his troubles are over. We shall know soon, for Hdqrs. left Washington yesterday and will probably reach here to-morrow.
Though just a brief addendum to the letter, there are many observations which match well into the narrative of the crossing. The time line given by Folwell is consistent with that of the official reports. The mention of a misty rain is duly noted. Furthermore, Hooker’s concern, clearly recorded here by Folwell, about the wagons and further delays, should receive a highlight.
On a lower level, we get a small glimpse into engineer operations during a crossing. There is much “just wait, watch, and stand ready” for them during such a crossing. As Folwell said, “an old story” by this point in the war. It is significant that Beers spent time at Folwell’s tent during the morning. I’ve always felt, based on comments by other officers, Beers was the type of leader to be at the most critical point. And Folwell’s place, on the Maryland side of the crossing, would be that critical point – should repairs be needed, another bridge be required, or yet another set of orders come down.
We often associate the C&O Canal with mule-drawn boats. But steam-powered boats were operated, as the C&O Canal Association reminds us.
Poor Mahalon, though. His “troubles” were that of additional duties. Presumably, those would be over when the main body of the 50th New York Engineers moved up from Washington. A small, personal aspect of the crossing which would probably have escaped record, had we not consulted Folwell’s letters. Later in the evening, Folwell would start a fresh new letter, offering more observations on a most active day at Edwards Ferry.
