I managed to get along to the club on Thursday and Eric the Spy put on a 15mm WW1 game using Great War Spearhead.
I like the basic WW2 Spearhead rules (although you do need to turn the Germans stats down from invincible!) and the Great War amendments are interesting but the way they have laid out the supplement is just a pain! Unlike Modern Spearhead they chose to produce a separate supplement which isn't stand alone. You are constantly finding yourself being referred back to the original rules which, for in game reference, is hopeless.
The game itself was fun with me taking command of the camelry and attacking up the right flank with Ben and Crazy Dave advancing with the infantry and artillery in the centre. We also had a slightly sneaky flank march by the cavalry (which was very late arriving many due to my dodgy dice rolling).
As we started our attack at night visibility was initially restricted and so I managed to stumble into some barbed wire fronting some entrenched Turks (with machine guns of course!). We took some serioud casualties on the lead unit both from artillery and the infantry who were in the trenches but managed to dismount and start to hit back. Fortunately the Turks had anchored their flank on a wood rather than running their line through it and so my dismounted infantry were able to advance through it an outflank their position.
Meanwhile our main thrust was encountering some resistance from the Turks in the centre but giving as good as they got.
The Turks chose to aim their reinforcements at my outflanking troops rather than bolstering the centre and so the game ended in a British victory albeit a costly one.
