Janissaire was one of four Chasseur-class destroyers built for the French Navy in the first decade of the 20th century.

Design and description[edit]

The Chasseur class was based on the preceding Spahi-class destroyer, albeit oil-fired boilers rather than the coal-fired ones of the earlier ships.[1] Janissaire had an length between perpendiculars of 64.5 meters (211 ft 7 in), a beam of 6.6 meters (21 ft 8 in),[2] and a draft of 3.1 meters (10 ft 2 in). Designed to displaced 450 metric tons (443 long tons), the ships displaced 520 t (512 long tons) at deep load. Their crew numbered 77–79 men.[1]

Janissaire was powered by three Parsons direct-drive steam turbines, each driving one propeller shaft, using steam provided by three Foster-Wheeler boilers. The engines were designed to produce 7,200 shaft horsepower (5,400 kW) which was intended to give the ships a speed of 28 knots (52 km/h; 32 mph). Janissaire exceeded that speed during her sea trials, reaching 28.6 knots (53.0 km/h; 32.9 mph). The ships carried enough fuel oil to give them a range of 1,400–1,500 nautical miles (2,600–2,800 km; 1,600–1,700 mi) at a cruising speed of 10 knots (19 km/h; 12 mph).[3]

The primary armament of the Chasseur-class ships consisted of six 65-millimeter (2.6 in) Modèle 1902 guns in single mounts, one each fore and aft of the superstructure and the others were distributed amidships. They were also fitted with three 450-millimeter (17.7 in) torpedo tubes. One of these was in a fixed mount in the bow and the other two were on single rotating mounts amidships.[1]

Construction and career[edit]

Janissaire was ordered from Ateliers et Chantiers de Penhoët and was launched from its Saint-Nazaire shipyard on 12 April 1910. The ship was completed in June 1911.[4] When the First World War began in August 1914, Janissaire was assigned to the 3rd Destroyer Flotilla (3e 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.[5]

The torpedoing of the French battleship Jean Bart on 21 December caused a change in French tactics as the battleships were too important to risk to submarine attack. Henceforth, only the destroyers would escort the transports. After Italy signed the Treaty of London and declared war on the Austro-Hungarian Empire on 23 May 1915, Boué de Lapeyrère reorganized his forces in late June to cover the approaches to the Adriatic and interdict merchant shipping of the Central Powers since the Royal Italian Navy (Regia Marina) now had primary responsibility for the Adriatic itself. His area of responsibility extended from Sardinia to Crete and he divided it into two zones with the 1st Light Squadron assigned to the western zone and the 2nd Light Squadron in the east. Those destroyers of the 1st Naval Army not assigned to reinforce the Italians were transferred to the newly formed 1st and 2nd Flotillas of the Naval Army (flotille d'Armée navale). The 1st and 3rd Destroyer Flotillas were assigned to the 2nd Flotilla of the Naval Army, of which the destroyer Dehorter was the flagship, which was tasked to support the cruisers of the 2nd Light Division.[6]
