.. trains and horse
drawn wagons was how their logistics moved..
The Germans were way under motorized for
Blitzkrieg in the east. Only about 20%. of the
army was such...and more wouldn't help coz
they didn't have the oil.
A train could transport the equal of some
1000+lorries... and they had the coal to fuel
them... but the management of the rail system
was a nightmare with trains tangled / banked up
on lines unable to reach destinations toward the
advancing front...operating at about 50% of rail
capacity.
When Case Blue failed in later part of 42" the
Germans were fortunate that it coincided with
the train backlog being cleared. There was so
much fuel on those trains that it allowed the
Germans to keep fighting for a number of months,
otherwise they would have been screwed.
When Case Blue started, at one point Paulus
had to wait two weeks for fuel, and 1st Panzer
( gruppe A headed for the Caucasus) ran out
of fuel..When 4th Panzer came to assist Paulus
in his push toward Stalingrad, it had supply issues
and was restricted in how it could help.
Hitler put enormous emphasis on how vital
success was for gruppe A/B to succeed in
Case Blue/Edelweiss or else Germany was out
of the war, yet even such a high priority 72 div.
taskforce could not be properly supplied.
Horses were slow and vulnerable to attack,
they didn't have enough of them and fueling
them was an issue, as fodder like gasoline
and ammunition had to be transported coz
the lanscape did not offer much.
=======
Spearhead Panzers/armored units that could
advance many km in short time, having to rely
on critical supplies by horse and infantry on foot
to hold and consolidate gains made... Hmmm
Hitler told others it would work, saying the soviets
were so weak that they would totally collapse after
Germany kicked their door in.
But when soviets showed strong resistance and
German intelligence and logistics failed.. things
went pear shaped for Hitler's rather audacious
roll of the dice dreams of conquest.
