Very nice game. Thank you for sharing the pictures and AAR.
I saw some Sikh Guns at Woolwich in the '90's. I tried to do the Sikh wars in 15mm from Fuedal Castings. but it didn't go far due to not finding rules which I felt gave a good replay of the battles.
I did restart the project a few years ago with the release of the Black Hat range. I had at one point prior thought to sell off the figures, but am very glad I didn't.
Rules wise, we tried Volley & Bayonet, but I felt it felt like Napoleonic's with Indian figures. (Hardly surprising)
A few years ago my friend got Field of Battle 2nd Ed. and we've been fine tuning them. They feel really good to me how units can go forth but be unsupported by their mates, etc. All the small things which you read about from the histories.
I keep playing different versions of battles based on Mudkee or Aliwal.
I'm hoping to next try a version of Ferozeshah but by going with Gough's original plan before Hardinge stuck his oar in. Have Littler's division show up later as per historically.
I've attached pics of one of our battles inspired by Mudkee, using 15mm Black Hat and QRF (now, the old Fuedal Castings) figures.
