Introduction

The Siege of Budapest was one of the longest and bloodiest battles of WWII.  Between the  appearance of the first  Soviet  tank and the final capture of Buda Castle, 102 days were to pass.  In comparison, Berlin and Vienna  fell after 2 weeks and 6 days respectively, while no other European city, with the exception of Warsaw, was the scene of a major battle.  Even those German units  that  persevered  the  longest,  like Königsberg (Kaliningrad) and  Breslau (Wroclaw),  resisted the attackers for 77 and 82 days respectively.  The fierceness  of  the  battle  of  Budapest  can  be  compared only to the sieges of Leningrad  (St. Petersburg),  Stalingrad (Volgograd) and Warsaw.  Budapest has been  one  of  the  most  besieged  capital cities in Europe, which bares witness to  its  strategic  importance:  there  have been 15 different major battles fought  here  throughout  history,  yet  not one of them comes close to the siege of 1944-1945 in the scope of its destruction. The stifling of the Warsaw uprising took 63  days,  the  blockade  of  Leningrad lasted almost 3 years but no battles were fought  on the streets.  Stalingrad was a combat zone for 4 months, but most of the  civilian  population  was  evacuated prior to the struggle.  At the same time, more  than 800,000 people  were  eyewitnesses  to  the  bloody  conflict  that contemporaries  compared to Stalingrad in its ferocity. The casualties of the Red Army were 80,026 dead and 240,056 wounded during the military operations in Budapest  and  its  vicinity,  and  for  each  Soviet soldier killed elsewhere in Hungary, two  lost  their  lives  in  the  capital  city.  The material damage was also great.
The  entire German-Hungarian loss of life amounted to about 60% of Red Army losses.   Between  November 3,  1944 and February 16, 1945, there were about 40,000  dead  and  62,000  wounded  (including  victims  of  the attempt to break out of the blockade).  In  terms  of  numbers, Hungarian losses did not surpass that of the  Germans  and  were a far cry from the Soviet casualties.  However, this was the most inane sacrifice of all three.  Regardless of his allegiance, the Hungarian soldier  was  but  a  spectator of the destruction of his country.  Many felt that it was  their duty to fight even when  the outcome was obvious, others capitulated right  away  citing  Horthy Miklós' order of cease-fire.  To chose meant to wager between  the  lesser  of  two  evils:  persistence  only  prolonged the bloody war initiated for the wrong cause, capitulation did not ensure true liberation. During the  siege,  very  few took  the  risk  of taking photographs.  Almost all pictures taken  by  the  defenders  were  destroyed.   Therefore  this  exhibition primarily presents materials of the Soviet  war correspondents and civilians, as well as the pictures taken after the siege. For this very reason, there is virtually no evidence of several  significant  events  and important people.  The street battles, the atrocities or the anti-Fascist resistance cannot be revisited either. When planning this  exhibition,  we  worked  from  materials  that  were  at  posterity's disposal, therefore, it is primarily buildings that feature in the photographs.  Nevertheless, this does not diminish the tragedy of the thousands who  perished  in  the  midst  of  those  destroyed  buildings.  This  exhibition  commemorates these human destinies.
