Page "Siege of Budapest" Paragraph 16

Meanwhile, urban warfare in Budapest increased in intensity.

Re-supply became a decisive factor because of the loss of the Ferihegy airport just before the start of the siege, on 27 December 1944.

Until 9 January 1945, German troops were able to use some of the main avenues as well as the park next to Buda Castle as landing zones for planes and gliders, although they were under constant artillery fire from the Soviets.

Before the Danube froze, some supplies could be sent on barges, under the cover of darkness and fog.
