Frontier defences in the east had been erected before the First World War. New fortifications were then constructed during the Weimar Republic, when Poland was seen as a major military threat. The pre-war years of the Third Reich had seen these extended and new defences built. Despite rapid acceleration of construction work, and one stretch of almost 80 kilometres along the Oder–Warthe rivers that was more heavily fortified than the
On 28 July 1944, transmitting Hitler’s decree of the previous day for the construction of fortifications in the east, Guderian, the newly appointed Chief of the Army General Staff, declared that ‘the whole of eastern Germany must immediately become a single deep-echeloned fortress’. The State Secretary in the Reich Ministry of the Interior, Wilhelm Stuckart, amplified the order, laying out details for implementation of the construction work to the eastern Gauleiter and Hans Frank, boss of the General Government. The fortification workers would need spades, pickaxes, blankets, eating utensils and marching rations. Their overseers were to have pistols and other weapons—a hint of the possible need for harsh action to stamp their authority on a recalcitrant workforce. The Reich Transport Ministry and railway authorities would organize transport. Building materials and equipment would come from OT offices. Horses and carts were to be used as far as possible for carrying the building materials. Rations would be allocated through provincial food offices or, in the case of the General Government, through deep inroads into the provisions of the region.28
At the beginning of September, Hitler made it clear that command over the fortification work was exclusively in the hands of the Party, to be deployed by the RKVs under Bormann’s direction.29
In reality, the Gauleiter, as RKVs, had a good deal of independence in the way they ran affairs in their provinces. Erich Koch, the brutal Gauleiter of East Prussia, one of Hitler’s favourite provincial chieftains, led the way in dragooning the population of his province into compulsory labour service. Already on 13 July he had decreed that the entire male population of specified districts between the ages of fifteen and sixty-five were to be conscripted with immediate effect for fortification work. Anyone defying the order would be subject to punishment by military court. Shops and businesses not absolutely necessary for the war effort were closed and their owners and workers sent to dig. Trains leaving the East Prussian border were controlled, and men taken off them and brought back for construction work.30 Koch’s example was followed by the other eastern Gauleiter. A report from Königsberg in East Prussia, noted by British intelligence authorities, indicates the effect of the conscription on daily life in the province.Great simplifications have been introduced in the everyday life of the population. In restaurants guests must go to the kitchen with their plate, so that all waiters and male kitchen staff can dig. The newspapers no longer publish regional editions but only one standard edition. Thus editors, compositors and printers are released for digging. Every business which is not of importance to the war has been closed. Every East Prussian fit for military service has been called up. The large gates of Königsberg University have been closed. The students and all men employed at the University are digging.
Even harvest workers were taken away at the most crucial point of the agricultural year to dig, though in separate waves so that the garnering of the harvest was not impaired.31
