 A week or so after the battle an allied army occupied the city without resistance.On 1 November, the ex-Austro-Hungarian dreadnought flagship "Viribus Unitis" was sunk — along with the merchant-ship "Wien"— both at anchor at Pula by limpet mine attached by the crew of an Italian "mignatta" (human torpedo).The "mignatta" was the precursor of the human torpedo and was invented by Major of naval engineers Raffaele Rossetti.
