John Sedgwick
The Whitworth rifle saw extensive use with the Confederate sharpshooters in the American Civil War, claiming the lives of several Union generals, including John Sedgwick, one of the highest-ranking Union officers killed during the Civil War, shot on 9 May 1864, at Spotsylvania. On October 2017, a surviving example of a Confederate Whitworth rifle was auctioned with a hammer price of $161,000.
