Such cases led to branding becoming obsolete, and it was abolished in 1829 except in the case of deserters from the army, who were marked with the letter D, not with hot irons but by tattooing with ink or gunpowder. Notoriously bad soldiers were also branded with BC (bad character). The British Mutiny Act of 1858 provided that the court-martial might, in addition to any other penalty, order deserters to be marked on the left side, 2 inches (5 cm) below the armpit, with the letter D, such letter to be not less than an inch long. In 1879 this was abolished.
