1st September 1939
The attack begins with air attacks on the Modlin, Pomorze and Lodz Armies. Only the attacks against Lodz prove successful.
The German plan is to surround – and effectively neutralise - the Polish armies, while sweeping forward toward Warsaw. As a result of the focus being on territory, only one army and one cavalry brigade are destroyed.
4th Army
The Frontier Guard Command in Pomerania set out to surround and cut off the Pomorska Cavalry Brigade in the ‘Corridor’, while to the south II and III Corps neutralise the Poznan Army. In a stunning display of incompetence, III Corps runs headlong into the Poznan Army and suffers serious casualties. However, II Corps pushes south at Bydoszcz and encircles the defenders of Western Poland. This allows the panzer and motorised divisions of XIX Corps to race east, just falling short of capturing Torun.
3rd Army
Good progress here. I and XXI Corps isolate the remnants of the Modlin Army, which was heavily attacked by 3rd Army, and halt on the north bank of the Bug.
8th Army
The infantry of 8th Army are used to smash the Lodz Army and then X Corps act as the western pincer to cut off the surviving Polish forces in this sector.
10th Army
The eastern pincer for the surrounding of Lodz is the armour of XVI Corps. The lead elements of 4th Panzer Division just fail to take Lodz itself however. 10th Army and XI Corps surround the Krakow Army.
14th Army
The plan here was to push past the Karpaty Army, using VIII and XXII Corps, supported by a Slovakian Corps. Progress is naturally slow in the Carpathians. To the west the 14th Army are used to attack the 10th Mechanised Brigade, which is badly shot up.
