My beautiful girlfriend the formidable Inquisitor Athena was my opponent this time around. She would command a force of Crimson Fists (the inquisitor would herself be controlling things from orbit and wouldn't be on the battlefield) whilst I would head a force of Rogue Trader era Salamanders.
The battlefield would be made of tradition retro war games scenery supplements with a 'Pegasus Models River' with a rather nifty bridge that was actually bought from the fish tank section of my local pet shop!
The battling forces would be identical each consisting of one Captain with a Bolter and Power Axe; two five man tactical squads with bolters; one five man assault squad with bolt pistols and one five man terminator squad with storm bolters (I still like to keep things simple weapon-wise while we get used to the rules.
