The Battle of Cove Mountain occurred in Wythe County, Virginia, on May 10, 1864, during the American Civil War. A Union cavalry division commanded by Brigadier General William W. Averell was prevented from attacking a lead mine located near Wytheville. Confederate forces commanded by Brigadier General John Hunt Morgan, with a detachment of a brigade of cavalry from the command of Brigadier General William E. "Grumble" Jones, stopped Averell at Cove Gap<!--NOT WEST VIRGINIA-->, adjacent to Crockett's Cove and Cove Mountain.
Averell and a larger force commanded by Brigadier General George Crook were part of a Union plan to damage the Confederate-controlled Virginia and Tennessee Railroad. The railroad was used by the Confederacy to transport soldiers and supplies, and served important lead and salt mines. Averell's assignment was to attack the mines, but he was stopped at the cove while attempting to reach the lead mine. After an escape through the mountains during the night, Averell's cavalry was pursued by multiple Confederate forces for five days until his cavalry reunited with Crook's force in Union, West Virginia.
The National Park Service lists the result of this battle as "indecisive". Confederate accounts call the battle a victory for Morgan. Confederate troops prevented Averell from destroying a salt mine, and a lead mine, that were important to the Confederacy for preserving meat and making bullets. However, because of Confederate concern about Averell's intentions, most of the forces commanded by Jones and Morgan could not assist at the Battle of Cloyd's Mountain where Crook's 6,000-man legion had a significant victory. Crook was able to complete his objective to destroy a large railroad bridge across the New River, and important Confederate railroad infrastructure was damaged.

During March 1864, Lieutenant General Ulysses S. Grant became commander of all Union armed forces. Grant's strategy in Virginia was to attack the strongest Confederate Army, Robert E. Lee's Army of Northern Virginia, from multiple fronts. Among targets were the Virginia and Tennessee Railroad and the Virginia Central Railroad, which carried food east from the Shenandoah Valley to help feed Lee's army. Troops also moved between battlefronts on both railroads. The Virginia and Tennessee Railroad helped connect the Confederate capital of Richmond with Tennessee, and was used to move minerals such as salt and lead to Knoxville, Tennessee, and to Virginia factories in Lynchburg, Petersburg, and Richmond.
Brigadier General George Crook was assigned the task of attacking the Virginia and Tennessee Railroad. His force was three brigades of infantry and dismounted cavalry, plus two batteries, that totaled 6,155 men. Four hundred more men were added shortly thereafter. Crook sent a smaller force, commanded by Brigadier General William W. Averell, to attack a salt mine further west from Crook.
The Battle of Cove Mountain occurred during Averell's movements to accomplish his portion of Grant's plan. Averell's target salt mine was located in Saltville, Virginia. During 1864, this salt mine produced an estimated two thirds of the salt used by the Confederacy.
From deserters and prisoners, Averell learned that the Confederate Army was aware of his Saltville objective and the size of his force. He also learned that 4,500 Confederate troops led by John Hunt Morgan and William "Grumble" Jones were waiting for his force (about 2,000 men) at Saltville. Given that information, Averell decided to attack the railroad further east at Wytheville, occupying Morgan and Jones so they could not intercept Crook. As Averell moved east, Morgan began following him.
At the junction of the Jeffersonville, Crab Orchard, and Wytheville roads, Averell continued moving east in the mountains toward Crab Orchard—a rugged road and a longer route to Wytheville. The Richmond Enquirer called the location "Crockett's Gap".
Schoonmaker's 14th Pennsylvania and 1st West Virginia cavalries opened the battle by driving back the advanced guard of the Confederate force that occupied the gap. When the Union cavalry got too close to the gap, dismounted Confederate cavalry on both sides of the gap drove them back. While the regiment was waiting, a member of the regiment's CompanyH climbed up a tree and observed the Confederate position being reinforced. This was reported to Duffié, and the charge was cancelled. Although not known by Averell at the time, reinforcements (including Morgan's brigades) were positioning on both sides of the gap, and a cannon masked by brush was positioned in the road. Unable to penetrate the gap, and aware of the Confederate reinforcements, Averell's command fell back and formed a line of battle to lure the Confederates out into the cove. A large Confederate force came out of the gap, and more fighting began.
Averell's forehead was grazed by a bullet early in the fighting—a slight wound that bled profusely. Powell divided the 2nd West Virginia Cavalry into platoons, and gradually moved it back with the precision of what Averell called a "dress parade that continued without disorder under heavy fire".
