Here is the AAR and photos for a scenario from 'All Fine Men', the upcoming second Great War Spearhead Eastern Front supplement:Link
The action was part of the Battle of Gumbinnen, fought in August 1914. The battlefield is based on actual topographic maps of the area, reproduced using Hexon terrain under the terrain mat. You can see the effect in the photo entitled 'Rolling East Prussian countryside'. The terrain makes all the difference in a game like this, adding a level of complexity to the decision-making.
The figures are a mix of Heroics and Ros (Russian guns and some German infantry), Baccus (uhlans and some German infantry), and Irregular Miniatures (Russian infantry and cavalry; German guns).
