I brought some 3 MM thick laser cut midfield hexagons to put under the terrain tiles. 4 hexes make a good hill and 2 a decent wood.
I brought them from Warbases.co.uk at 1.20 GBPounds for 7 so good value. Very impressed with the service and quality.
There are in Europe many good generals, but they see too many things at once. I see one thing, namely the enemy's main body. I try to crush it, confident that secondary matters will then settle themselves. ~Napoleon
