In the North German plain armoured units from I German and I British Corps, extricated with some difficulty from encirclement, were now regrouping north of Hannover to face the main threat pressing down upon them from the north and east. The North German plain was no longer the wide open tank-run it had still been held to be (perhaps even then no longer correctly) a decade or so before. Villages had become townships, offering opportunities for anti-tank delaying action which the Germans and the British had been quick to seize, developing tactical practices already referred to which had much in common. Operating in small and inconspicuous detachments, with
Both in the urban development of the North German plain and, with appropriate adjustment, in the hill country of the Harz, these tactics began to show promise, even on the first day, of a significant capacity for the absorption of armoured impetus. The depth of the enemy’s penetration by nightfall on the 4th had certainly not been as great in the NORTHAG sector as he must have hoped. It was still great enough, nonetheless, to put the army group’s ability to retain its balance in some doubt.
In the NORTHAG sector, as elsewhere in the Central Region, another serious problem was emerging. An immense, sprawling swarm of civilian refugees from the towns and villages of Niedersachsen was already beginning to cause the difficulties that had long been foreseen — and feared. It was greatly to the Soviet advantage to increase disorder wherever possible, while trying to keep clear the main axes of their advance. Ground-attack aircraft maintained a ceaseless rain of machine-gun fire along these axes, with small anti-personnel fragmentation bombs, the Soviet intention clearly being not so much to cause casualties (though they minded little about these) as to drive refugee traffic off any roads they intended to use. Armoured engineer equipment moving with leading tanks swept derelict civilian vehicles to one side without noticeable loss of momentum to the advancing columns. The tanks themselves were driven without hesitation through groups of people vainly struggling to get clear, charging on at high speeds over human wreckage already pulped by vehicles ahead of them. Some side roads soon became jammed, and Allied troops were being seriously impeded by a chaotic mass of pedestrians and vehicles which it was nearly impossible, in spite of heroic and efficient work by German police and Home Defence units, to control.
In the CENTAG sector, with III German Corps on the left under pressure and pinned down, it had become clear by early afternoon on the 4th that a major thrust directed towards Hersfeld was developing on the left of V US Corps, with a secondary effort through Fulda towards Hanau, along the Kinzig river valley and the ridges running south-west to the Rhine-Main plain. The covering force of reinforced US armoured cavalry had used its anti-tank weapons and artillery admirably from first light onwards, making good use of favourable terrain to slow the enemy’s advance. It had even been found possible to turn the great numbers of the enemy’s vehicles to his disadvantage by blocking defiles which it then took time to clear. In this the F-15 aircraft of the US Air Force, having already established a clear superiority in air-to-air action, were particularly effective, operating in a secondary ground-attack role.
