Austrian War (1866).
Venice, Pola, &c., protected by Torpedoes.—During this war, torpedoes for the defence of Venice, Pola, &c., were extensively used by the Austrians, under the direction of Baron von Ebner, but as in '59 no opportunity was afforded of proving their practical worth, though morally they were of great value, the Austrian harbours so defended being considered impregnable by the enemy, and therefore no attempt was made to force them.
