French destroyer Cognée

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

Construction and career
When the First World War began in August 1914, Cognée was assigned to the 5th Destroyer Flotilla (5e escadrille de torpilleurs) of the 1st Naval Army (1ère Armée Navale). During the preliminary stages of the Battle of Antivari on 16 August, 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.

On 26 November, Cognée and her sister ships FRENCH DESTROYER Trident and FRENCH DESTROYER Coutelas escorted the predreadnought battleships FRENCH BATTLESHIP Saint Louis and FRENCH BATTLESHIP Charlemagne to join the Anglo-French forces blockading the Dardanelles to prevent a breakout into the Mediterranean by the ex-German battlecruiser TCG Yavuz Sultan Selim and light cruiser TURKISH CRUISER Midilli. By February 1915 they had been joined by the rest of the Fifth Destroyer Flotilla, FRENCH DESTROYER Poignard and her sisters FRENCH DESTROYER Sabretache and FRENCH DESTROYER Fanfare.
