The Battle of Cinghinarele Island was a military engagement between Central Powers forces (Germany and Austria-Hungary) on one side and Romanian forces on the other side during the Romanian Campaign of World War I. It took place in early October 1916. In late September 1916, Romanian forces occupied the island, setting up a garrison comprising an infantry company and six guns in two batteries. On 2 October, in support of the Flămânda Offensive, the Romanian garrison on the island attacked bypassing Austro-Hungarian warships, inflicting some damage and delaying the naval group long enough to allow the Romanian bridge over the Danube to be repaired. However, after an artillery bombardment which started on 7 October, the island was taken by the Central Powers on the 8th, the Romanian garrison being captured.
