Difficult terrain includes the following:

• Brush, scrub and other clinging vegetation.

• Debris, wreckage, loose rocks and boulders.

• Fords, streams and shallow water.

• Marshes, bogs and thick mud.

• Freshly ploughed, flooded and muddy fields.

• Sand dunes and areas of deep sand.

• Stairs, steps and ladders.

• Steep or treacherous slopes. This can include particular hills if both players agree before the game, but otherwise hills are considered to be 'open' terrain.

• Woods, orchards, growing crops and other dense foliage.

Troops cross difficult ground at 1/2 speed. So if your unit has a move of 4" it can only move 2" through a wood.

If troops move over open ground and difficult terrain during the same turn, then their movement over the open ground is at full speed and that over difficult ground is reduced to 1/2 speed exactly as normal. For example, a Man moves 2" across open ground and then enters a wood. He now has 2" of his move left. This is covered at half speed for the difficult terrain so he only move a further 1" through the wood.
