The First Battle of Cobadin, also known as the First Battle of the Rasova–Cobadin–Tuzla Line, was fought from 17 to 19 of September 1916 between the Bulgarian Third Army and the Romanian–Russian Army of the Dobruja. The battle ended in Entente tactical victory and forced the Central Powers to hold their offensive and assume a defensive stance till the middle of October.

The right flank of the Allied forces was supported by the Romanian Navy's Danube Flotilla, consisting mainly of four Brătianu-class river monitors. These warships blocked with mines the river sectors of Silistra, Ostrov, and Gura Borcea, protected the 8 September evacuation of Silistra, attacked enemy land convoys, and destroyed enemy batteries.^[3]
