R. Smg. Alabastro

The submarine Alabaster, a boat of the 600 type class, Platino series, was built by the CRDA shipyard of Monfalcone and launched on December 18th, 1941. It did not enter service until May 9th, 1942. After completion, final fitting and crew training took place at a rapid pace to make the submarine operational as quickly as possible.

On 13 September 1942, under the command of Lieutenant Giuseppe Bonadies, the Alabaster left Cagliari for his first offensive mission, to be carried out between Algiers and Mallorca. It was the first and last operational patrol.

After the end of the conflict, it was learned that at 4.20 PM on 14 September 1942 north of Bougie, a British Short Sunderland seaplane belonging to the 202nd Wing of the Royal Air Force9Australian crews) had attacked a submarine sailing on the surface towards the west, sinking it. It is most likely that it was Alabaster.

Commander Giuseppe Bonadies, 4 other officers and 39 non-commissioned officers and sailors were lost with the submarine. As common practice at the time, the crew was not officially considered missing until a month after their disappearance, on 13 October 1942.

The Alabaster had carried out a single offensive patrol and 4 exploratory ones, for a total of 1554 miles of navigation, all on the surface.
