This skirmish might spark such a conflict. Melas Thirytis should be a fairly strong castle, with high walls and a central keep. It lies alongside a tertiary canal. The Martian artillery should begin emplaced but uncrewed. If the canal bisects that side the Belgian player may choose which side of the canal he enters on.
All units begin in column, and the guns are limbered.
One company of infantry may carry 6 scaling ladders. It is imperative that the Belgian player act as if he were unaware of the approach of the Tossian cavalry until it arrives on board. All units below follow standard Soldier's Companion organizations and numbers. The Nectaran Forces To win the Martians simply need to hold the castle. I've played this scenario 5 or 6 times.
