Army Group C was on the western border of Germany defending against a potential French attack. This order of battle is for 04:47 on September 1, after which things started to get shuffled.[a]
Oberkommando des Heeres
Oberkommando des Heeres was the High Command of the Heer. It controlled everything related to the Heer: Personnel, Training, Recruitment, Armaments, Transportation, Supplies, Medical Services, etc. An ongoing problem was that each service branch was its own "kingdom" resulting in massive inefficiency.
Chef des Generalstab des Heeres General der Artillerie Franz Halder
Chief of the General Staff of the Army was the head of all of the departments of the Heer except for the armaments section and the replacement army.
Chef der Heeresrüstung und Befehlshaber des Ersatzheeres General der Artillerie Friedrich "Fritz" Fromm
Chief of Armaments and Commander of the Replacement Army controlled all army procurement and production, and all of the troops within Germany who were replacements for front line units.
Heeresgruppe Nord's initial objectives were to capture the "Polish corridor" (4. Armee) and drive southwards towards Warsaw from East Prussia (3. Armee)[c]
Heeresgruppe C's 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.
On August 30 the Polish Navy, realizing what was about to happen, sent three destroyers (Błyskawica, Grom, and Burza) to the UK. The group was spotted the 30th in the southern Baltic Sea by U 31[as] and again, in the Skagerrak, by U 19 on 31 August. Since the war had not started they were unmolested. With the destroyers gone some of the ships deployed to the Baltic were recalled and some sent to the North Sea. The fleet was in the process of shifting its deployment when the war broke out. Later, the submarines Orzeł and Wilk also made it to the UK, while the Sęp, Ryś and Żbik, sought internment in Sweden.
