During World War II, she operated on the Allied side until 1940, when she became part of the naval forces of Vichy France.

Ordered under the 1923 naval programme,[1] Eurydice was laid down along with her sister ship Danaé[2] at Chantiers et Ateliers Augustin Normand in Le Havre, France, on 3 July 1923 with the hull number Q123.

On 3 July 1940, the British began Operation Catapult, which sought to seize or neutralize the ships of the French Navy to prevent their use by the Germans, and Eurydice was in port at the French naval base at Mers El Kébir at Oran that day when a British naval squadron arrived off the base and demanded that the French Navy either turn over the ships based there to British custody or disable them.

[1] They anchored in the outer harbor at 15:30 with Ariane and Danaé,[1] and at 17:54 the four submarines received orders to put to sea.

[1] When the British warships opened fire on the French ships in the harbor at 17:57,[1] beginning their attack on Mers-el-Kébir, Eurydice was 4.5 nautical miles (8.3 km; 5.2 mi) southwest of Danaé.

[1] As Operation Catapult continued, British forces attacked the French squadron at Dakar in Senegal on 8 July 1940.

[1] Receiving word of the attack, French naval authorities at Oran ordered Eurydice, Ariane, and Diane to form a patrol line off Cape Falcon, Algeria.

[1] On 14 May 1941, she was placed under guard at Toulon, France, in an unarmed and unfueled status in accordance with the terms of the 22 June 1940 armistice.

[1] Eurydice still was in this status when Germany and Italy occupied the Free Zone (French: Zone libre) of Vichy France on 27 November 1942, and she was among the French vessels scuttled at Toulon to prevent their seizure by Germany when German forces entered Toulon that day, sinking in the Northwest Basin at the Missiessy Docks.

[1] The Germans declared her unusable on 26 January 1944 and moved her to Brégaillon,[1] where Allied bombers sank her on 22 June 1944.
