We used pretty much the same stats from our LotR game last week except now Rohan was British military force and the Defender was a group of Pirates. The "gunmen" that turn traitor on the "its a trap " card were natives (proxies by Zulu figures)..
Major Tom reached the plot point on turn 2, but of course I pulled the "it's a trap" card and all the reinforcements flooded in!
The entire British force was taken down, except for Major Tom, who held out to the last turn to earn the victory.
