1.Topazio (TP)7 Sep 19431612La Maddalena12 Sep 1943Sunk with all handsSailed with Turchese until she parted on 10th September (she was also seen by Diaspro on the previous day), when on Anzio parallel, slightly east of 11°E. Part of a barrage line with Diaspro, Turchese and Marea in the Gulf of Salerno. On 8th September, she was ordered along with all other submarines, to dive to 80 meters then to surface only at 0800 hours on the 9th and display the Italian flag with a black flag of surrender. Then to proceed to Bone. At 1117 hours on the 12th, an RAF bomber (Bisley "J" of 13 Squadron) reported attacking a surfaced submarine. This was most likely Topazio. It is not clear if she was on her way to surrender. She disappeared without a trace (six officers, forty-three ratings missing).

1117 (e)

(e) 38° 39'N, 9° 22'E
At 1117 hours, a Bisley from 13 Squadron piloted by Flying Officer G.H. Finch when a submarine was seen slightly down by the stern and making less than 10 knots. Using the cloud cover, the aircraft surprised the submarine with a stick of four depth charges from 50 feet. One of the them exploded within 10 yards of the conning tower. The submarine attempted to make a recognition signal and was completely obscured by plumes and, when they cleared, she was gone. A growing oil slick was visible and some 15-20 men in the water were photographed by the aircraft.

This submarine was initially believed to have been Turchese, who arrived later in Bone, but it was most probably Topazio. T.V. Pier Vittorio Casarini, five officers, and forty-three ratings perished. It was a tragedy that could have been avoided.
