 The ship was thereafter transferred to Brindisi for use as a harbor defense ship . The reason for her withdrawal was the major Italian defeat at the Battle of Caporetto ; the German and Austro @-@ Hungarian advance threatened to continue to Venice . Here , all of her secondary and light guns were removed , leaving her with only her main battery guns . She was equipped with a small battery of anti @-@ aircraft guns , consisting of four 3 in ( 76 mm ) / 40 guns and two machine guns . On 10 June 1918 , Sardegna was moved to Taranto , where she continued serving as a guard ship . She took part in Allied operations in Constantinople after the end of the war , from 7 November 1919 to 5 April 1922 . The ship did not remain in service long after returning to Italy . She was stricken on 4 January 1923 and subsequently broken up for scrap .
