 On 16 August 1914 the combined Anglo-French Fleet under Admiral Auguste Boué de Lapeyrère, including "Voltaire", made a sweep of the Adriatic Sea.The Allied ships encountered the Austro-Hungarian cruiser , escorted by the destroyer , blockading the coast of Montenegro.There were too many ships for "Zenta" to escape, so she remained behind to allow "Ulan" to get away and was sunk by gunfire during the Battle of Antivari off the coast of Bar, Montenegro.
