World War I

Louis Dartige du Fournet in 1915.

France entered World War I in August 1914, and Dartige du Fournet became commander of the newly created French 3rd Squadron in February 1915, with the battleship Saint Louis as his flagship.^[2] Based in Syria or at Port Said in Egypt (according to different sources), the squadron became responsible for enforcing the blockade of the Ottoman Empire decreed in August 1915.^[4]

Dartige du Fournet took command of the Allied Dardanelles Squadron in September 1915^[2][5] with the battleship France as his flagship.^[2] He instigated the development of the French insular strategy in the Eastern Mediterranean, in which, as part of the fight against the Ottoman Empire, the French Navy took possession of the islands of Rouad in September 1915 and Kastellorizo in December 1915.^[6] It set up particularly active intelligence centers there which operated throughout the war.

On 5 September 1915, Armenians entrenched on Musa Dagh^[4] ("Mount Moses") to resist the Armenian genocide undertaken by the Ottoman Turks used a white bed sheet marked with a red cross to attract the attention of the French protected cruiser Guichen, which was operating north of the Bay of Antioch under the command of Captain Jean-Joseph Brisson. After Brisson brought the Armenians' desperate situation to his attention, Dartige du Fournet sought instructions from the French general staff. Receiving no clear answer, he took upon himself the responsibility for evacuating the Armenians, 4,080 of whom embarked on Guichen, the armored cruisers Amiral Charner and Desaix, the protected cruiser D'Estrées, and the seaplane carrier Foudre^[7] on 12 and 13 September 1915. The ships transported them to Port Saïd. Dartige du Fournet continues to be regarded as a hero by Armenians for his actions in September 1915.

On 10 October 1915, Dartige du Fournet replaced Vide Admiral Augustin Boué de Lapeyrère as Allied commander in the Mediterranean Sea. He became a Grand officer of the Legion of Honour on 8 January 1916.^[2] He directed the evacuation of the Serbian Army^[2] from Albania, which was completed in February 1916. He received the Croix de Guerre with palms,^[2] the citation reading, that he had "demonstrated the finest military qualities, both in the exercise of his current command and in those of the Algerian-Tunisian district and the 'Syrian Squadron.'"^[2]

Dartige du Fournet in Piraeus, Greece, 26 November 1916.

After an Allied force had landed at Salonica in neutral Greece in September 1915 both to defend Salonica and support the hard-pressed Serbian Army in its struggle to defend Serbia against a Central Powers offensive, the National Schism developed in Greece between pro-Allied Prime Minister Eleftherios Venizelos and the pro-Central Powers King Constantine I.^[8] In the autumn of 1916, Venizelos and his supporters created a separate Greek government at Salonica, and the French then led Allied efforts to pressure Consdtantine I into a more pro-Allied stance.^[8] Although he disliked interfering in the affairs of a neutral country, Dartige du Fournet aboard his flagship, the battleship Provence, led a French naval squadron into the Bay of Salamis which seized and disarmed the Royal Hellenic Navy fleet^[8] on 11 October 1916. In late November 1916, the French demanded that the Greek royalist army provide arms and ammunition for pro-Allied Greek volunteers fighting on the Salonica front and, after the Greek government failed to comply, Dartige du Fournet steamed a French naval force into the harbor at Piraeus, Greece, on 1 December 1916 (18 November according to the Julian calendar then used in Greece) and went ashore with a landing party of French sailors in a show of force he believed would intimidate the Greek government into meeting the French demands, beginning what is known as the Noemvriana ("November Events") or "Greek Vespers."^[8] After Dartige du Fournet and his landing party reached Athens, the Greeks still refused to turn over any arms or ammunition and, to the surprise of the French, a battle broke out in which Dartige du Fournet and his party were cut off from the harbor.^[8] Torpedo boats and the French battleship Mirabeau shelled Athens to enable the French ashore to disengage.^[8] Dartige du Fournet finally negotiated a ceasefire after 70 French sailors were killed, and the vastly outnumbered French retreated to Piraeus and withdrew by sea on 3 December 1916.^[8]

Admiral Lucien Lacaze, the French Minister of the Navy, criticized Dartige du Fournet for refusing to bombard Athens more vigorously and accused him of weakness and recklessness.^[2] Lacaze relieved him of command on 11 December 1916^[2] and replaced him with Admiral Dominique-Marie Gauchet on 12 December 1916.^[9][10] Dartige du Fournet transferred to the naval reserve in February 1917.^[2]

Dartige du Fournet sought to reintegrate into the French Navy during the last months of World War I.^[11] He was rehabilitated by the end of the war, but married and retired in 1918 to his villa, Paknam, in Périgueux, France.
