We used the Warhammer Historical "Great War" rules for the game. The British had a battalion led by Major Graves, comprising two companies (three and two platoons led by Captain Blunden and Captain Sassoon respectively) with attached assault platoon and Highlanders platoon, three Vickers MGs, an 18-pounder gun and two MK IV male tanks. In reserve they held a cavalry squadron of two troops plus HQ element.
Well, the game ended as expected - the British had made a minor gain on their right flank but the Germans reinforced their supports so the Brits would be in for a fight to hold on. I think when we play this game again I'll start the British a bit farther onto the table - maybe 12" in rather than the 3" or so in this game. It just gives a bit less ground for them to cover. Of course, starting in closer can be a slight disadvantage for them too, as their MGs have fewer turns with clear fields of fire, so that's a nice tradeoff. I'd tweak the rules slightly as well, to allow a "run" move of d6" in the Close Assault phase for troops who didn't shoot.
All in all I think a very successful and enjoyable lunch and game. The terrain sure looks great and I think everyone had a good time and enough fine food to eat - which is the whole point of the New Year's game.
All the best to you and yours for the New Year, and roll on 2015!
