The 1st West Virginia Cavalry Regiment served in the Union Army during the American Civil War. Although it started slowly, it became one of the most active and effective of the West Virginia Civil War regiments—and had 14 Medal of Honor recipients, the most for any West Virginia regiment during the war. It was originally called the 1st Virginia Cavalry, not to be confused with the Confederate 1st Virginia Cavalry. Some reports added "Union," "Loyal" or "West" when identifying this regiment. After the Unionist state of West Virginia was officially admitted to the Union in 1863, the regiment became the 1st West Virginia Cavalry Regiment. The National Park Service identifies it as the 1st Regiment, West Virginia Cavalry.

William Henry Powell was an American soldier who fought for the Union in the American Civil War. He was a leader in the iron and nail business before the war, and his leadership abilities proved useful in the military. Powell began as a captain, and quickly ascended to higher roles in the cavalry, including commanding a regiment, a brigade, and then a division. Powell was awarded his country's highest award for bravery during combat, the Medal of Honor, for heroism at Sinking Creek, Virginia, when, as leader of a group of 22 men, he captured an enemy camp and took over 100 prisoners. This was accomplished without the loss of any of his men on November 26, 1862. He was honored with the award on July 22, 1890.
