First you have to have an imagination. It can guide you as to the composition you wish to create. Next you must consider your medium, whether you are using charcoal, pen and ink, etc., and what you are drawing on Often what you use to draw dictates a kind of inspiration or dynamism for the drawing and what you draw on sets restrictions and advantages towards what you are trying to craft.
Many of the best artists research their drawings. They study pictures, sketches from the actual battle and time period, eye-witness accounts, correspondence, etc. Some even study the individual weapons, areas and people involved in the battle to better render them realistically in place, use and design.
