tained only by the crazy regime of pills prescribed by his doctor,
the sinister Theodor Morell.
Hitler was also isolated in the geographic sense. On 16 De-
cember 1944 he moved his headquarters to the Adlerhorst at
Ziegenberg, in the wooded Hessian hills near Giessen, to co-
incide with the opening of the German offensive in the Ar-
dennes. In the middle of January he was back at Berlin, where
the concrete of his bunker and the massive Chancellery above
gave him protection against bombs of 1,000 kilograms or more.
'Zossen [i.e. the headquarters of the General Staff] is in-
secure—not because it was impossible to make it secure, but
because it was built by the army and not a private construction
firm. . . . Everything the Wehrmacht puts up is a fraud' (Hitler,
23 March 1945, Schramm, ed„ 1982, IV, 1,657).
Hitler stirred from his lair less and less frequently, and it
required a crippling effort on the part of the chief of staff,
Colonel-General Heinz Guderian, to supply the Führer with
the detailed briefings he required twice daily—at noon, and
again after midnight. Guderian writes that the drive from Zos-
sen took forty minutes, making three hours lost on the road
for the two round trips, to which was added the time spent in
preparing the material, and the duration of the briefings them-
selves, which often lasted two hours each. Even when relays
of staff officers took on some of the briefings in January, they
still had to be rehearsed in the presence of Guderian.
The main visual material for the Führer briefings was pro-
vided by situation maps which were updated constantly by the
Operations Branch of the General Staff. 'Enemy attacks were
clearly plotted on the maps by means of red arrows, so that
one could not fail to see them. Moreover, there was a legend
provided at the side of the maps displaying, clearly arranged
in graphic form, the current status of the individual units'
(Humboldt, 1986, 93). The scale of the briefing maps was
1:300,000, a significantly small scale which was capable of dis-
playing only one theatre of war at a time. General Hans Krebs,
