The artillery pieces and the crew are Old Glory 25's, while the wagon and oxen are Foundry figures that I didn't know what else to do with.
Artillery is usually of not much use in most Ancient rule sets focusing on open field battles, so these haven't been getting much use for me. It seems that they will probably make it onto a tabletop more often as figures in a baggage camp than as fighting elements. By the way, the relative ineffectiveness of battlefield artillery in pre-1500 warfare is in all probably not misrepresented by miniature wargaming rules - their lack of mobility, and slow rate of fire actually made them simple to maneuver around. Of course, on the other hand, the static nature of siege warfare is something completely different, and if I find a set of siege (or campaign) rules that I really like, these figures may still find their way back to the front, instead of the rear, of a battlefield for me.
