Simon put on a game using the Pz8 WW1 Division/Corps rules. I'd looked at these previously but thought they looked a bit overly abstract for my usual outings to WW1, but given the option to actually play with them, I was keen to give them a go.
They are pitched at a similar level to my own Drumfire with battalion sized stands and roughly a Corps on the table. The artillery is abstracted out as a set of support points which add to attacks.
This was a scenario based on Cambrai, Tim and I had the British with the equivalent of three infantry divisions, plus some tanks and a cavalry division arriving later. John and Mark were the wicked Germans.
