Mountain warfare
This page shows some photographs of Swiss troops in the mountains. Mountainous terrain features in central and southern Switzerland more than the north, so it would probably not have featured in an invasion of Switzerland by one of the warring countries. However mountains do make for a good photograph!

Over fifty soldiers pulling an artillery gun uphill. Was this a regular occurrence, or done just for the camera?
