During the First World War, the Romanian Danube Flotilla was deployed in coordinated operations with the Romanian Army, which prevented the Central Powers from advancing into the Danube Delta. The Flotilla made a significant contribution to the Battle of Turtucaia and later carried out the safe evacuation of the Romanian 9th division from the besieged city. During the summer and fall of 1917, in conjunction with the artillery of the ground troops, the Flotilla held the line against renewed German offensive in Moldavia. Throughout the 1917 operations, the artillery of the four monitors bombarded enemy naval positions scoring notable successes, under the skillful command of the Romanian Vice-Admiral Constantin Bălescu.
