French destroyer Cavalier
Cavalier was one of four s built for the French Navy in the first decade of the 20th century.
Design and description
The Chasseur class was based on the preceding, albeit oil-fired boilers rather than the coal-fired ones of the earlier ships. Cavalier had a length between perpendiculars of, a beam of, and a draft of. Designed to displaced, the ships displaced at deep load. Their crew numbered 77–79 men.The Chasseur class was powered by three Parsons direct-drive steam turbines, each driving one propeller shaft, using steam provided by four Normand boilers. The engines were designed to produce which was intended to give the ships a speed of. Cavalier exceeded that speed during her sea trials, reaching. The ships carried enough fuel oil to give them a range of at a cruising speed of.
The primary armament of the Chasseur-class ships consisted of six 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 torpedo tubes. One of these was in a fixed mount in the bow and the other two were on single rotating mounts amidships.
Construction and career
Cavalier was ordered from Chantiers et Ateliers Augustin Normand and was launched from its Le Havre shipyard on 9 May 1910. The ship was completed in January 1911. When the First World War began in August 1914, Cavalier was assigned to the 3rd Destroyer Flotilla of the 1st Naval Army. 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 and two British cruisers. After reuniting both groups and spotting the Austro-Hungarian protected cruiser and the destroyer, 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, Vice-Admiral 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.The torpedoing of the 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. On 26 March 1915, the badly damaged predreadnought battleship radioed for help as she was taking on water in a storm off the Greek coast. Cavalier, her sister ship, the destroyer and the armored cruiser responded, but were unable to render assistance due to the heavy weather.
After Italy signed the Treaty of London and declared war on the Austro-Hungarian Empire on 23 May, 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 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. The 1st and 3rd Destroyer Flotillas were assigned to the 2nd Flotilla of the Naval Army, of which the destroyer was the flagship, which was tasked to support the cruisers of the 2nd Light Division.
