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 Kďż˝nigsberg (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.
