After fitting @-@ out work was completed , the ship was commissioned into the fleet on 1 September 1892 . During the 1893 fleet maneuvers , Aretusa served with the 3rd Division of the Reserve Squadron , along with the protected cruisers <unk> and <unk> <unk> and four torpedo boats . During the maneuvers , which lasted from 6 August to 5 September , the ships of the Reserve Squadron defended against a simulated attack by the Active Squadron , which <unk> a French attack on the Italian fleet . In 1895 , Aretusa was stationed in the 2nd Maritime Department , split between Taranto and Naples , along with most of the torpedo cruisers in the Italian fleet . These included her sister ships <unk> , Minerva , <unk> , <unk> , Urania , and Caprera , the four <unk> @-@ class cruisers , and Tripoli . As of 1898 , Aretusa was assigned to the Active Squadron , with included the ironclads <unk> and <unk> and two other cruisers . 
 At the start of the Italo @-@ Turkish War in September 1911 , Aretusa was stationed in Italian Eritrea in the Red Sea Squadron . Italian naval forces in the region also included five protected cruisers and several smaller vessels . Shortly after the start of the war on 2 October , Aretusa and the gunboat Volturno encountered the Ottoman torpedo cruiser <unk> @-@ i <unk> off Al Hudaydah . In a short engagement , the Italians vessels forced the Ottoman ship to flee into Al Hudaydah , bombarded the port facilities , and then withdrew . <unk> @-@ i <unk> was later interned in British @-@ controlled Suez The threat of an Ottoman attack from the Arabian Peninsula led the Italian High Command to reinforce the Red Sea Squadron ; the additional ships included another cruiser and several destroyers . The protected cruiser <unk> and two destroyers annihilated a force of seven Ottoman gunboats in the Battle of <unk> Bay on 7 January 1912 . 
 Following the <unk> of Ottoman naval forces in the region , Aretusa and the rest of the Italian ships then commenced a bombardment campaign against the Turkish ports in the Red Sea before declaring a blockade of the city of Al Hudaydah on 26 January . On 27 July and 12 August , Aretusa , her sister ship Caprera , and <unk> conducted two bombardments of Al Hudaydah . During the second attack , they destroyed an Ottoman ammunition dump . With the threat of an Ottoman attack greatly reduced , the High Command thereafter began to withdraw forces from the Red Sea Squadron . By the end of August , the unit was reduced to three protected cruisers , Aretusa , Caprera and two <unk> . On 14 October , the Ottoman government agreed to sign a peace treaty , ending the war . Aretusa 's career ended shortly thereafter ; the Regia Marina discarded the ship in December and she was subsequently broken up for scrap .
