Italian (RSI) submarine patrols in the Mediterranean during February 1945
| C.B.6 (…2 February) | C.B.20? (…1 February) | C.B.6 (25 February) |
| C.B.18 (25 February…) |
On 25 February, C.B.6 (ex-C.B.17) and C.B.18 of the Italian Socialist Republic sailed from Pola to operate against a reported enemy landing at Pag (Croatia). The former had to turn back due to defects, and the latter obtained no results.
Italian submarine exercises continued with almost no interruption, except for an occasional U-boat scare as the one occurring on 6 February off Casco Bay (Maine). The destroyer USS Trippe (DD-403), on an independent patrol, obtained a contact at 1859 hours, some 20 miles south of Portland. Aware that an Italian submarine had been exercising during the day in the area and confused by echoes, which seemed to indicate the submarine was “friendly,” she was reluctant to attack. When it was learned that Mameli had already returned to port, a general alarm was given and Mameli (T.V. Cesare Buldrini) was ordered to stay in port, her exercises cancelled for the next two days, while destroyers took part in a real antisubmarine hunt. The U-boat may have been U-869, believed to have been sunk on 11 February off the New Jersey coast. She was thought to have come from the north; her wreck was found in 1991. Her loss was attributed to the destroyers USS Koiner (DE-331) and Howard D. Crow (DE-252), although, at that time, the attack was believed to have been on a non-sub contact. Koiner was one of the destroyers training with Mameli on 6 February, so we can conclude that the lessons were useful.
On 27 February, Tito Speri (T.V. Claudio Celli) and Da Procida (T.V. Francesco Castracane degli Antelminelli) sailed from Port Royal (Bermuda) for Guantanamo (Cuba) to conduct anti-submarine training.
