His artistic method prioritised the energy of cavalry skirmishes and the daily routines of soldiers. He often employed a low horizon line to make his riders appear larger against the clouds. Martszen de Jonge brought the viewer close to the action, focusing on the anatomy of horses and the specific details of military dress. His etchings use precise lines to suggest the dust of a battlefield or the quiet tension of soldiers outside a tavern. This focus on the horse as a central subject makes his work distinct from broader battle panoramas.

Modern collectors appreciate these works for their historical accuracy and graphic strength. His prints offer a view of the Dutch Golden Age that is active rather than static. The monochromatic etchings provide a sharp aesthetic that works well in contemporary rooms. These pieces remain interesting because they capture the specific equipment and tactics of a past era with factual clarity. They represent a specific niche of Dutch art that values documentation and motion over the stillness of typical genre painting.
