French destroyer Pierrer

Pierrier was one of 13 Claymore-class destroyers built for the French Navy in the first decade of the 20th century.

Construction and career
Pierrier was ordered on 5 August 1903 and was laid down at the Arsenal de Rochefort on 6 October 1904. The ship was launched on 28 February 1907 and was assigned to the Northern Squadron after her completion in November 1907. The ship was placed in reserve at Rochefort in September 1909 and was reactivated in January 1911. She then transferred to the Oran Local Defenses (Défense mobilie d'Oran) in French Algeria in 1912 and was assigned to the 4th Destroyer Flotilla (4e escadrille de torpilleurs) of the 1st Naval Army (1ère Armée Navale) in 1913.

During the preliminary stages of the Battle of Antivari on 16 August 1914, the 1st, 4th and 5th Destroyer Flotillas were tasked to escort the core of the 1st Naval Army while the 2nd, 3rd and 6th Flotillas escorted the armored cruisers of the 2nd Light Squadron (2e escadre légère) and two British cruisers. After reuniting both groups and spotting the Austro-Hungarian protected cruiser SMS Zenta and the destroyer SMS Ulan, the French destroyers played no role in sinking the cruiser, although the 4th Flotilla was sent on an unsuccessful pursuit of Ulan. 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, escorted by the 2nd Light Squadron and the 1st and 6th Destroyer Flotillas 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 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.

Pierrier was transferred to the 7th Destroyer Flotilla to serve off the coast of Turkish Syria in 1916 remained with that unit until the end of the war two years later. Pierrier was struck from the naval register on 27 July 1921 and sold for scrap on 1 March 1922.
