Background and detail

Danube Campaign. Following the Ottoman ultimatum, forces under General Omar Pasha crossed the Danube at Vidin in October 1853. Ottoman troops captured Calafat, establishing a foothold in Wallachia. This campaign aimed to drive Russian forces out of the western Danubian Principalities. The crossing and subsequent engagements marked the initial land operations of the war, preceding the major allied interventions of 1854.

Naval Engagements. The naval phase began with the destruction of the Ottoman squadron at Sinop in November 1853. A Russian fleet assaulted the harbour, annihilating the Ottoman force. This event caused public outrage in Britain and France, influencing their decision to join the war in 1854. The battle demonstrated Russian naval superiority in the Black Sea during the opening months of the conflict.
