World War II Howitzer

During World War I and World War II, Switzerland maintained armed neutrality and was not invaded by its neighbors, in part because of its heavily mountainous terrain. Switzerland built up its defence capabilities during this period to guard against an attack from neighbouring Germany, which never occurred. It served as a protecting power for the belligerents of both sides, with a special role in helping prisoners of war. The belligerent states made Switzerland a scene for diplomacy, espionage, and commerce, as well as a safe haven for 300,000 refugees.
