By 1944, the German Eastern Front's situation became hopeless.
Adolf Hitler who took over personally many duties in the
OKW and OKH ordered the
no step back policy in an attempt to halt the
Soviet offensives which could not be contained by
open field battle anymore. Following this policy, several cities were declared
Festungen (
Fortresses) and were to be held by the German army at all costs, even if surrounded and with no hope to break the siege. Examples of this policy were the
Festung Stalingrad and
Festung Kiev. Later in the war, the "Festung" concept that was to be illustrated by the
propaganda film Kolberg which reminds of Kolberg's defense against Napoleon in 1807, was also applied to German cities like
Königsberg,
Breslau,
Frankfurt (Oder) and
Berlin. Often even the civil population was supposed to support the rather suicidal attempts of defense, as the cities were largely destroyed in the course of the fights. On 27 July 1944, Adolf Hitler ordered the
Festung Warschau to be created and defended at all cost. The same day the governor of the
General Government,
Hans Frank, called for 100,000 Polish men between the ages of 17–65 to arrive at several gathering places in Warsaw the following day. They were to be employed at construction of fortifications for the
Wehrmacht in and around the city. This move was viewed by the
Armia Krajowa as an attempt to neutralize the underground forces, and the underground urged Warsaw inhabitants to ignore it. Fearing that the city would be turned into ruins and share the fate of
Stalingrad and
Kiev, General
Tadeusz Bór-Komorowski ordered
Operation Tempest to be started in Warsaw, which resulted in the
Warsaw Uprising that lasted from August through September. After the Uprising, during which the Soviets troops had arrived near the
Vistula, the Germans
razed the city to the ground and continued the construction of concrete bunkers that were to defend
Festung Warschau against the
Red Army for four months. However, when the Soviets finally crossed the
Vistula on 17 January 1945, the city was captured in several hours with little resistance from the remaining German garrison. The Chief of the Operational Branch of the German Army General Staff (Generalstab des Heeres), Colonel
Bogislaw von Bonin, gave permission for the retreat of German
Heeresgruppe A from
Warsaw on 16 January 1945, throughout the Soviet
Vistula-Oder Offensive and was imprisoned on 19 January 1945 by the
Gestapo at
Flossenbürg concentration camp and
Dachau concentration camp as he rejected a direct command of
Adolf Hitler by this action. ==Notes and references==
