 On 4 November Italian troops entered Pola and seized Tegetthoff and Prinz Eugen . The Italians kept Tegetthoff for their own use , although they broke her up in 1924 following the Washington Naval Treaty of 1922 , but she had first featured in the movie Eroi di nostri mari ( Heroes of our seas ) about the sinking of Szent István . Prinz Eugen became French property — they removed the main armament for inspection and used the ship to test aerial bombardment attacks , before she was finally used as a target ship by the battleships Paris , Jean Bart , and France , and sunk in the Atlantic .
