It was totally unrealistic, because it could not be imple-
mented at short notice and would have required roads, trains
and ships. It should be remembered that at the time the Allied
air forces had complete air supremacy, flying freely through-
out the length and breadth of Germany. Such troop move-
ments as did get under way, according to Guderian,
'proceeded very slowly, and the enemy air supremacy com-
pletely paralysed not only troop transportation, but also the
will of the Command.' (Chuikov, 1978, 163)
The shortage of petrol restricted the use which could be made
of roads for approach marches, and not just by the tanks, with
the limited duration of their tracks, but by all kinds of vehicles.
This limitation impeded the buildup of forces for Operation
Sonnenwende towards the middle of February. Again it was
principally to regain the full use of the perpendicular railway
between Lusatia, Lower Silesia and Upper Silesia that the Ger-
mans thought it worth their while to undertake their offensive
at Lauban at the beginning of March.
Lateral, movement behind the Eastern Front was a truly des-
perate affair, in which the pace was dictated by the Russians.
As Goebbels explained, 'We have to shuffle our units about to
the hot spots like a fire brigade in order to plug the holes as
best we can, suffering severely in the process' (Goebbels, 1977,
32).
There was no guarantee that the tanks would be able to
detrain before they reached the scene of the fighting. On the
snowy 6 March the 4th Panzer Division was dispatched from
Bütow in the direction of Neustadt in West Prussia, and
we travelled . . . into the milky unknown with mixed feel-
ings. The situation was unclear. We knew absolutely nothing
about the enemy. There was no more aerial reconnaissance,
and not even any kind of short-range reconnaissance by our
recce detachments, because we did not have the requisite
fuel. For this reason all the crews were ordered to occupy
