The units which had been cut off beyond the Oder were lost
beyond recall, and the German High Command feared that the
Soviets might seize a further prize—the containers of liquid
poison gas that were held near the village of Dyhernfurth, on
the enemy bank of the Oder below Breslau.
It was one of the oddities of the Second World War that none
of the belligerents went so far as to employ poison gas in war-
fare. However, they continued the necessary research and de-
velopment, and at Dyhernfurth the Germans had large stocks
of some of their latest and deadliest toxins. The Fourth Panzer
Army was told that it was not enough to raid the factory and
blow up the tanks, for sufficient residue would be left to be
analysed by the Russians. The Germans must therefore seize
the factory and hold it long enough to permit the liquid to be
pumped into the Oder. Gräser entrusted this delicate operation
to Major-General Max Sachsenheimer.
At first Fourth Panzer Army envisaged a conventional attack,
complete with an artillery bombardment, and a set-piece assault
delivered by two companies of 'dismounted' parachutists who
were summoned from neighbouring army groups. Sachsen-
heimer analysed his task more closely and grasped that the
essence must be to secure enough time to enable the pumping-
out to go ahead undisturbed. This could best be achieved by a
swift and silent strike with the forces immediately at hand,
formed into a little battle group of several hundred infantry,
two batteries of dual-purpose 88-mm guns, and a light pioneer
assault boat company with eighty-one craft. Two scientists and
eighty technicians provided the expert help.
On a personal reconnaissance Sachsenheimer saw that the
railway bridge to Dyhernfurth was intact, apart from the two
spans nearest the 'German' bank, and that it was guarded only
by two machine-guns, one on each side of the railway em-
bankment on the far bank. Beyond the Oder the railway curved
left past Dyhernfurth, and a spur line led directly into the
wooded compound of the chemical factory, which meant that
the Germans could not go far astray if they simply followed
