Thunderbolt to the Rebels: The United States Sharpshooters in the Civil War

Sharpshooters were the elite of the Union army. Clad in green uniforms and equipped with the era's latest rifles and scopes, they took up positions out in front of the infantry, where they targeted Confederate officers or skirmished with enemy soldiers. However they were used, sharpshooters formed an important presence on battlefields throughout the Civil War, and yet most accounts have tended to focus on their distinctive uniforms and cutting-edge equipment rather than on their combat performance. Thunderbolt to the Rebels tells the story of these Civil War deadeyes on battlefields from Antietam to Gettysburg and beyond.

During the first year of the Civil War, Hiram Berdan proposed the creation of a unit of marksmen armed with Sharps rifles, and thus were born the 1st and 2nd U.S. Sharpshooters. Drawn heavily from the Upper Midwest and New England, as well as Pennsylvania, the soldiers had to pass a marksmanship test to join: 10 shots in a 10-inch-diameter circle from 200 yards. They were issued green uniforms for better camouflage, which also helped Confederate riflemen target them. The job of a sharpshooter was dangerous and demanding - much of it out in front of the army, much of it alone - but they made a difference on the battlefield.

Thunderbolt to the Rebels uses primary sources, especially eyewitness accounts, to reveal how these elite marksmen lived, fought, and died during the Civil War.
