I always fancied doing the last invasion of Britain, Fishguard in Wales, where the French surrendered to the militia because they saw British regulars appear on the surrounding hills. There were no British regulars anywhere near, it was in fact lots of local women in traditional Welsh costume (red jacket with black hats) curious to see the expected battle. This I would recreate by laying lots of British line infantry on a side table that the French player could see while making copius references about reenforcements. I did something similar in a WW2 game. It was set in the early stages of Barbarossa. The German players were made well aware of how fantastic the Russian T34s & KV 1s were compared to their Pz IIIs. Lots of T34s & some KV 1s were placed on a side table for the Germans to see. The Russian attack came during the night (poor visability) Much was made of hearing Russian tanks moving closer. The German players started withdrawing, this soon turned into a near rout as they all sought to get back across the bridge to their rear. When the Russian tanks came into view I put on several early war light tanks, but by then the Germans had given up their advantages. I never lie to players, but often fail to tell ALL the truth.
