German order of battle for the invasion of Poland

This article details the order of battle of German military units during the invasion of Poland in 1939.
The German army's forces for the invasion of Poland (codename "Fall Weiss," English - "Case White") were divided into Army Group North (consisting of the German 3rd and 4th armies) and Army Group South (consisting of the German 8th, 10th, and 14th armies, and the Slovak Army Group "Bernolak").
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.
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.

Heeresgruppe C.
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.

Kriegsmarine.
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 and again, in the Skagerrak, by U 19 on 31 August. Since the war hadn't 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 ("Nordsee"). 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.
