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. As the inscription relays, this painting depicts Private James Harmer of the 10th (The Prince of Wales's Own) Royal Hussars. The Hussars were a regiment of light cavalry mounted on particularly fast horses, used in skirmishes and for reconnaissance duties. Taking their name and function from Hungarian cavalry forces, the British Army’s Hussars developed out of Light Dragoon regiments from the beginning of 19th century.

By painting the Private from behind, Drahonet showcases the new Hussar pelisse (worn slung over the shoulder), which was now red, following William IV’s preference for the colour. Where earlier in the century the Hussars had worn a fur cap, all regiments had by now adopted the shako, modelled on that of the Light Dragoons, but with a black rather than white plume. The Private wears the white overalls permitted in the summer months.
