In contrast to previous days, June 27th was a relatively orderly crossing at Edwards Ferry. While serious command issues rose and came to a sharp conclusion, the troops kept crossing the river. At least through the morning, Major-General Winfield S. Hancock remained in the Edwards Ferry vicinity, tracking movements.
First in the line of march on this morning 150 years ago was Brigadier-General Crawford’s Pennsylvania Reserves. He reported the command was on the bridges by 9:25 a.m. “I will join General Meade to-night. Sedgwick left Dranesville this morning. Road is encumbered by trains of Third Corps.”
Around the same time, Brigadier-General John Buford’s division crossed at Edwards Ferry, NOT the Mouth of the Monocacy as ordered the previous day. Here is one of those gaps of information that I’d love to resolve. Were the previous day’s orders countermanded? Apparently so, as Assistant Adjutant-General A.J. Alexander reported Buford’s movement. But I’d love to see the full conversation and what prompted the change.
Around mid-day, Hancock reported on the progress as he returned from Edwards Ferry:
General Sedgwick and part of his command have arrived and the trains are rapidly crossing. The supply train of the Fifth Corps and General Crawford’s trains are in advance. General Crawford’s troops have crossed. The artillery are well out on the road I came.
Around 1 p.m., headquarters inquired, via telegram, as to the state of the crossing. The response came at 8:35 that evening, from Brigadier-General Henry Benham, who at last had moved up from Washington:
I have been here awaiting the passage and taking up of the bridges since 11 a.m. During this time the cavalry supply train and about two-thirds of the Sixth Corps have crossed on lower bridge. Vermont Brigade and Wright’s division are now to cross on upper bridge. The First Division of cavalry have passed, and there is now passing the First Brigade of General Gregg’s division. It is now almost entirely across. I understood that this cavalry division was to be the last to cross.
So as the sunlight faded on June 27th, the last parts of the Army of the Potomac had left Virginia. Brigadier-General David M. Gregg brought the rear guard across, and the Army of the Potomac left Loudoun County. The only action left, with respect to activity in Loudoun, was to pull up the bridges.
(UPDATE: Minor change to the map today. Gregg’s cavalry division “took over the picket line” from Buford’s on June 26. I interpret that to mean Gregg stayed in the vicinity of Aldie until the morning of June 27. Gregg arrived in Leesburg around 1 p.m. that day.)
In his report, Benham added his concerns about pulling up the bridges in a timely manner. No doubt that sat well among the headquarters staff with whom he’d argued with over the last several days. Benham had a “land pontoon” train, with under 1,000 feet of bridging, ready to move from Poolesville. He planned to move remainder of bridging, that pulled out at Edwards Ferry, back to Washington by way of the C&O Canal. Some components of the bridges were out of the water by midnight (taking advantage of 83% moon illumination that particular night). But most of the work would wait for the following morning. Somewhat anti-climatic, but the great crossing was over.
One other Loudoun County crossing occurred, starting that evening and completing in the early hours of June 28. Major-General J.E.B. Stuart with three brigades of cavalry reappeared earlier on June 27 after taking a wide route around the marching Federal infantry. The Confederate troopers fought a brief engagement at Fairfax Courthouse. After a rest, the column moved to Dranesville where they found Sixth Corps campfires still warm and captured a few stragglers. But Stuart had orders to join with Lieutenant-General Richard Ewell somewhere in Pennsylvania. To get there, he needed a safe crossing of the Potomac. And good fortune smiled on Stuart that evening. Rowser’s Ford, which depending on where you stand is on the extreme eastern tip of Loudoun County, was free of Federal pickets, according to a civilian who met Brigadier-General Wade Hampton. Although the river was higher than usual from the rains.
Hampton’s brigade crossed early in the night, but reported to me that it would be utterly impossible to cross artillery at that ford…. A ford lower down was examined, and found quite as impracticable from quicksand, rocks, and rugged banks. I, however, determined not to give it up without a trial, and before 12 o’clock that night, in spite of the difficulties, to all appearances insuperable, indomitable energy and resolute determination triumphed; every piece was brought safely over, and the entire command in bivouac on Maryland soil.
In all actuality, the crossing likely continued well into the early morning. But Stuart was across the Potomac, although a little late.
While Stuart crossed, on the other side of Maryland, Major-General George Meade received word he was the next commander of the Army of the Potomac. Exit Major-General Joseph Hooker.
