Moorefield

On August 7, 1864, mounted forces clashed near the South Branch of the Potomac River, just north of Moorefield in Hardy County, West Virginia, in an engagement that came to be known as the Battle of Moorefield. The National Park Service classifies this fight alongside Early's Washington Raid and the campaign against the B&O Railroad, and it stands as the final significant clash in the area before Philip Sheridan assumed command of Union forces in the Shenandoah Valley. For Brigadier General William W. Averell, this Union success capped a trio of major wins, following his earlier victories at Droop Mountain and Rutherford's Farm, and it reinforced his reputation as a commander who thrived when given independent command.

The chain of events began on July 30, when Confederate horsemen under Brigadier General John McCausland crossed north of the Potomac and set fire to much of Chambersburg, Pennsylvania. From there McCausland pushed westward, threatening additional towns as well as the Baltimore and Ohio Railroad. Averell, commanding a smaller body of cavalry, gave chase, but McCausland's men, mounted on fresher horses, managed to stay ahead of their pursuers and kept menacing settlements in their path. Eventually McCausland recrossed the Potomac and turned south, settling his troops between Moorefield and Romney, nearer to the former. He placed Bradley Johnson's brigade on the river's north bank while keeping his own brigade south of the water. The chosen ground favored rest for the exhausted horses far more than it protected the men, since McCausland believed Averell's column remained some 60 miles off near Hancock, Maryland. His assumption about Averell's location proved accurate at first, for the Union commander had indeed halted there to rest his mounts, but within days fresh reinforcements arrived and Averell was ordered back into pursuit.

Under cover of darkness on August 6, Averell's troopers crept toward the unsuspecting Confederate encampments. An advance party disguised in Confederate uniforms managed to seize every picket standing guard, clearing the way to the sleeping camps without raising alarm. When dawn broke on August 7, Averell unleashed his first brigade against Johnson's men on the river's north side. Caught largely asleep and with horses unsaddled, many Confederates in whole regiments simply fled the scene, abandoning both their weapons and the plunder carried from Chambersburg. McCausland's brigade, camped across the water, attempted to mount a defense but found itself just as unprepared for the assault. Averell then committed his second brigade, sending it splashing across the river to join the fight. Facing Union troopers equipped with sabers, six shot revolvers, and seven round repeating rifles, the scattered Confederate ranks stood little chance. By the encounter's end, more than 400 Confederate soldiers had been killed or taken prisoner, while Union losses stayed under 50. The defeat left lasting scars on the Confederate cavalry, which would never again hold the commanding position it had once enjoyed throughout the Shenandoah Valley.

Aftermath

With this engagement, Early's seven-battle campaign targeting the B&O Railroad came to a close. A Union soldier present at the fight put Confederate losses at roughly eight hundred men killed, wounded, and captured, while the National Park Service places the number closer to 500. According to the final tally, Averell's forces took 38 officers and 377 enlisted men prisoner, on top of killing at least 13 and wounding another 60. Given the swiftness of the Union assault, some Confederates who were initially seized managed to slip away while being marched to the rear, meaning actual capture figures may have run higher. For Averell, the triumph came at a cost of 11 dead (two of them officers), 18 wounded, and 13 taken prisoner, the latter likely stragglers picked up by McNeill's rangers, who worked the Moorefield region independently rather than bunking with McCausland's brigades.

Bitterness lingered between Johnson and McCausland, each pointing fingers at the other for the loss. McCausland would later claim that the disaster stemmed from Johnson's brigade being caught off guard, insisting he himself had known Averell was closing in and had issued the orders needed to meet him. Johnson, for his part, maintained he had followed every directive given to him, down to where his men camped and where pickets were stationed. He further noted that McCausland was absent from his own brigade at the critical moment, resting three miles away in Moorefield while his troops, utterly unprepared, came under attack. Johnson did not stop there, voicing outrage over what he called the disgraceful behavior of the troops during the expedition, particularly their treatment of civilians in Pennsylvania and Maryland. He described watches and pocketbooks being stolen in broad daylight, brooches, rings, and earrings regularly snatched, and homes ransacked around the clock. He even recounted an incident in which a soldier on the advance guard robbed a Catholic priest in Hancock of his gold watch as the clergyman walked home from Sunday services.

The win at Moorefield added to Averell's growing reputation, though it also fit a pattern: he tended to shine when acting independently but struggled when forced to coordinate closely with other commanders. His resume already included victories at Droop Mountain and Rutherford's Farm, making him one of the rare Union cavalry officers to find success in the eastern theater before Sheridan took command. Major Stephen P. Halsey of the 21st Virginia called it one of the most brilliant achievements of the entire war, while Major Theodore F. Lang of the 6th West Virginia Cavalry described the battle as one of the Union's most decisive victories of the conflict.

The defeat gutted Early's cavalry presence in the Shenandoah Valley, cutting its strength roughly in half and shattering two of its stronger brigades. Morale among the survivors also took a severe hit. Early himself later admitted the battle had done lasting harm to his cavalry for the remainder of the campaign. Beyond its immediate toll, the victory signaled the start of lasting Union dominance in cavalry operations throughout the Shenandoah Valley.
