Named after the hamlet of Flămânda, the battle represented a consistent effort by the Romanian Army to stop the Central Powers' southern offensive led by August von Mackensen.

Meanwhile, a Central Powers force comprising Bulgarian, German and Turkish troops and led by August von Mackensen entered Dobruja in southeastern Romania.

[1] Facing more serious threats than expected, the Romanian Crown Council decided to reinforce the 3rd Army, led by General Alexandru Averescu, with 150,000 more men.

[2] The attack commenced on 29 September 1916 on an 80 km-wide (50 mi) front from Flămânda, near Oltenița, to Zimnicea in the direction of Mackensen's western flank, with the Romanian forces enjoying superiority in numbers of infantry personnel and artillery equipment.

[7] An Austro-Hungarian coal barge was also shelled and damaged by the Romanian coastal artillery based on the Cinghineaua island, as was the river monitor Szamos with one 7 cm gun destroyed.

[8] Due to the deteriorating situation in Transylvania, General Averescu decided to cancel the offensive, ordering his troops back to the Romanian side of the river on 3 October after repairing the damaged parts of the bridge.
