heeresgruppe c was commanded by char. generaloberst z.v. wilhelm ritter von leeb. its only duty was to protect the western border of germany from any french attacks until stronger units could be sent back from the east. it was accomplished by deception. the units were generally under strength, most of the infantry unit were missing their heavy weapons platoons, and some entire battalions. there was almost no mobility, except for horses and bicycles. some of the units were headquarters only to give the impression of a larger presence.
