[2] The ships carried enough fuel oil to give them a range of 1,200–1,400 nautical miles (2,222–2,593 km; 1,381–1,611 mi) at cruising speeds of 12–14 knots (22–26 km/h; 14–16 mph).

The ship arrived at Toulon on 24 March 1912 and was assigned to the 1st Destroyer Flotilla (1ère escadrille de torpilleurs) of the 1st Naval Army on 1 April.

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.

[6] Fourche covered the evacuation of the Royal Serbian Army from Durazzo on 23–26 February 1916 and was unsuccessfully attacked by the Austro-Hungarian submarine SM U-16 on 24 April.

The destroyer was part of the covering force for an attack on the Albanian port of Medova by two Italian MAS boats on the night of 15/16 June.

The following week, the Austro-Hungarian submarine SM U-15 torpedoed the Italian auxiliary cruiser SS Città di Messina on 23 June, 20 nautical miles (37 km) east of Otranto, Italy, and then sank Fourche with a single torpedo as the destroyer attempted to rescue survivors from Città di Messina.
