During the period of peace following the Napoleonic Wars, increasingly elaborate (and often quite impractical) military attire was devised, particularly by George IV. By the time William IV came to the throne in 1830, uniforms had become too expensive and were simplified and adapted once again. The result of these changes was codified and promulgated in the 1831 Dress Regulations. These paintings were intended to provide a visual record of the recent changes to military dress. Their value is not only historical, however, but also aesthetic: Drahonet produces lively, slightly elongated figures, capturing their facial expressions and setting them in a variety of organic poses.

Each painting in the series depicts a single figure against a neutral background. Although their uniform and accoutrements are the focus, the sitters are often identified by name, as well as regiment and rank. Shown here is Sergeant Robert Smart of the 13th (1st Somersetshire) Regiment of Foot, a Light Infantry regiment.

By painting Smart from behind, Drahonet illustrates the ammunition pouch, sword, musket and bayonet hanging from his shoulder straps, as well as the tasselled sash worn by sergeants from 1830. Smart also wears the regimental red coatee with yellow facings and white shoulder wings, and the white trousers permitted during the summer months. His bell-topped shako is adorned with a dark green ball tuft, which had changed from green feathers in 1830.
