Siege of Izmail Day is observed in Russia every December 24 to commemorate the significant military victory of the Russian army during the Russo-Turkish War. This day honors the successful siege conducted by Generalissimo Alexander Suvorov on December 22, 1790, when Russian forces attacked the fortress of Izmail. Although several unsuccessful attempts were made earlier that year, the final assault resulted in the capture of the fortress after intense street fighting, leading to heavy losses for the Turkish army. The observance is part of the days of military honor established in the Russian Federation to celebrate the nation's military achievements. The date is significant as it reflects the historical context of the battle, which originally took place on December 11 according to the Julian calendar.
