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. This painting depicts a Sergeant of the 5th (Princess Charlotte of Wales's) Dragoon Guards. The 5th Dragoon Guards, renamed after George IV’s daughter Charlotte in 1804, were a Heavy Cavalry Regiment, employed to deliver shock charges on the battlefield and also to fight their adversaries hand-to-hand. Although the inscription does not name this Sergeant, the Muster Rolls of the period suggest that this was probably Sergeant Benjamin Gilliece. 

The figure, leaning on his carbine with his sabre and sabretache by his side, illustrates many of the key aspects of the Dragoon Guards’ uniform that had been developed during the previous decade: the red coatee with tails and the dark blue trousers with yellow stripes were standard. Unlike in the Household Cavalry, cuirasses were not worn, nor were moustaches permitted. The steel helmet, painted black with a curling bearskin crest, would be replaced by a new model in 1834.
