"Trotușul" during World War I was commanded by Lieutenant Aschinger Bruno. Along with the Romanian monitor "Mihail Kogălniceanu", she carried out the last action of the Romanian Navy during the war, which took place after Romania re-declared war on the Central Powers on 10 November 1918. In the morning of 11 November, three hours before the Allied Armistice with Germany was signed, the monitor and the torpedo boat occupied the port of Brăila, after the Germans retreated from the city. The two Romanian warships captured 77 assorted German vessels abandoned in the city's port (barges, tankers, tugs, floating cranes, motorboats).
