The attack was against the Italian cruisers <i><a href="/wiki/Italian_cruiser_Bolzano" title="Italian cruiser Bolzano">Bolzano</a></i> and <i><a href="/wiki/Italian_cruiser_Gorizia" title="Italian cruiser Gorizia">Gorizia</a></i>, which had been taken by the Germans after the Italian surrender. This was to thwart a German plan to sink them where they would block the harbour entrance. The mission also aimed to attack German U-boats in the harbour. British chariots would attack the cruisers whilst <i>Mariassalto's</i> Gamma Frogmen would attack U-boats penned in the harbour. On 2 June 1944 the Italian destroyer <a href="/wiki/Italian_destroyer_Grecale" title="Italian destroyer Grecale"><i>Grecale</i></a> sailed from <a href="/wiki/Bastia" title="Bastia">Bastia</a> in <a href="/wiki/Corsica" title="Corsica">Corsica</a> to <a href="/wiki/La_Spezia" title="La Spezia">La Spezia</a> carrying three speedboats, and Italian frogmen including <a href="/wiki/Luigi_Durand_De_La_Penne" class="mw-redirect" title="Luigi Durand De La Penne">Luigi Durand De La Penne</a>, and two British chariots. One chariot broke down and was abandoned, though the other successfully sank <i>Bolzano</i>. However, the <i>Gamma</i> men were unsuccessful in their attack on the U-boat pens. All the participants escaped, linking with partisan groups on land.<sup id="cite_ref-Kemp_p63_38-1" class="reference"><a href="#cite_note-Kemp_p63-38"><span class="cite-bracket">[</span>16<span class="cite-bracket">]</span></a></sup> </p><p>In April 1945 a final mission, Operation Toast, was planned.<sup id="cite_ref-39" class="reference"><a href="#cite_note-39"><span class="cite-bracket">[</span>17<span class="cite-bracket">]</span></a></sup> This was aimed at sinking the newly converted shipping liner now the aircraft carrier <i><a href="/wiki/Italian_aircraft_carrier_Aquila" title="Italian aircraft carrier Aquila">Aquila</a></i>, just completed in Genoa. For this <i>Mariassalto</i> men would make use of two British chariots, as they had none of their own SLCs available. On 18 April 1945 the destroyer <a href="/wiki/Italian_destroyer_Legionario" title="Italian destroyer Legionario"><i>Legionario</i></a>, carrying two high-speed motorboats equipped with chariots sailed from Venice for Genoa led by Captain Chavasse SOE and Forza. Both chariots were deployed and succeeded in penetrating the defences but found the hull of <i>Aquila</i> so encrusted with barnacles and seaweed the limpet mines could not be attached to it. The frogmen had to lay the charges on the seafloor of the outer harbour mole and when the charge exploded as planned the ship remained afloat in spite of the attack. All of the frogmen escaped safely. The German commander never put his extensive demolition plans for Genoa into action and thus Aquila was never sunk as a blockade to the harbour. </p> <div class="mw-heading mw-heading3"><h3
