Another significant use of the naval ram occurred during the Third Italian War of Independence (June to August 1866) at the battle of Lissa, between Italy and Austria. The Italian ironclad "Re d'Italia", damaged aft by gunfire, had no functioning rudder. Lying helpless in the water, she was struck three times by the Austrian "Erzherzog Ferdinand Max", the flagship of the Austrian Commander-in-Chief Admiral Tegetthoff. The Austrian ship retreated unharmed as the Italian vessel rolled over and sank.
