First Battle of Cobadin

The First Battle of Cobadin, also known as the First Battle of the Rasova - Cobadin - Tuzla Line was a battle fought from 17 to 19 of September 1916 between the Bulgarian Third Army and the Romanian-Russian Army of the Dobrogea. 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 the enemy land convoys and destroyed enemy batteries.
