The standard dummy of the T-34 was a well-tried design made
of wire and sacking, but care was taken to site more accurate
models at important points. Further dummies were cranked up
and down by ropes and windlasses, and a few specimens of
the genuine article cruised around to lend an air of verisimili-
tude.
The Germans were almost completely taken in. Their intel-
ligence firmly located that IV Guards Tank Corps in the area
of the Sixtieth Army, and they feared a major thrust in the
direction of Krakow. On a larger scale the Germans gravely
underestimated the genuine concentrations of force which
faced them in the three bridgeheads, and they missed the move-
ment of nine full armies and a tank corps which arrived to take
part in the central Polish offensive from STAVKA's reserve,
where they had been standing at the immediate disposal of
Stalin. The STAVKA reserve (RVGK) included all the tank ar-
mies, and had become 'the principal source of the forces needed
to create powerful strike groupings at the most important axes
at crucial times' (Dick, 1990, 108).
The logistic preparations were very thorough. Both Fronts
were well stocked with supplies when the offensive began, and
the example of Zhukov's army group indicates the kind of quan-
tities involved. Ammunition was given top priority, but the 1st
Belorussian Front also had to provide fuel for its 2,000-odd tanks
and assault guns, 7,000 trucks, 3,000 heavy artillery tractors
and 2,500 supporting aircraft, as well as a daily consumption
of 1,500 tons of bread and 220 tons of meat. The dumps were
filled with the help of 1,200 trains (with 68,000 individual wag-
gon-loads), and thousands of trucks were overhauled to carry
the supplies beyond the railheads.
The railway tracks through eastern Poland had been widened
to the Russian gauge, which was a heroic undertaking in itself,
and it was particularly difficult to transport the supplies on the
final stage across the Vistula to the bridgeheads, for the bridges
had only just been built by the Russian military engineers, and
they were few and not especially strong. In December the water
