As you can imagine, my first contact with Black Powder on a visit up Weardale required slightly more recent figures than I am used to and caused a few misgivings. I must thank Colin for his hospitality and a great day, with a fantastic result - a draw which we could both claim as a moral victory. Using a CS Grant table top teaser, my French had to hold up the advancing Prussians for long enough to prepare the bridge for detonation, then get as many of their troops back over the bridge as possible before blowing it up. I held Colin's Prussians and Bavarians off successfully but got very few troops back over the bridge.
At this point I intended to add a photobucket sideshow but I just can't get the link to work - so lots of photos instead. tells (most) of the story - unfortunately I don't seem to have taken any photos of the Imperial Guard marching bravely over the bridge then smartly back again.
I will have to reflect a bit on the Black Powder experience - I was interested to see whether I would be happy using it for refighting some of the Georland battles. I think they work well enough, though there are a few things I might find difficult in the long run. All was arranged through a forum where Colin and I realised we had worked together a good few years ago.
As mentioned in his comment below, Colin has now posted a much more detailed account of the scenario and action, with his pictures, on his blog here.
