The engines were designed to produce 15,000 shaft horsepower (11,000 kW) which was intended to give the ships a speed of 30 knots (56 km/h; 35 mph).

The ships carried enough fuel oil to give them a range of 1,450 nautical miles (2,690 km; 1,670 mi) at cruising speeds of 14 knots (26 km/h; 16 mph).

Having broken the Austro-Hungarian blockade of Antivari (now known as Bar), Vice-Admiral (Vice-amiral) Augustin Boué de Lapeyrère, commander of the 1st Naval Army, decided to ferry troops and supplies to the port using a small requisitioned passenger ship, SS Liamone, escorted by the 2nd Light Squadron, reinforced by the armored cruiser Ernest Renan, and escorted by the destroyer Bouclier with the 1st and 6th Destroyer Flotillas under command while the rest of the 1st Naval Army bombarded the Austro-Hungarian naval base at Cattaro, Montenegro, on 1 September.

Four days later, the fleet covered the evacuation of Danilo, Crown Prince of Montenegro, aboard Bouclier, to the Greek island of Corfu.

The flotilla escorted multiple small convoys loaded with supplies and equipment to Antivari, beginning in October and lasting for the rest of the year, always covered by the larger ships of the Naval Army in futile attempts to lure the Austro-Hungarian fleet into battle.
