Events

24-08-1938 : Laid Down
24-08-1938 : Launched
04-07-1939 : Completed
13-04-1940 : Tetrarch's first patrol was carried out in C9 - the Lillesand sector. The boat made what was thought to be an unsuccessful attack on a transport and as a result was depth-charged for 43 hours. Surfaced for 3 minutes in the middle of enemy vessels and fired torpedoes at A/S trawler
23-04-1940 : 18:30 Sighted a Southbound enemy convoy bearing 270, distance about 5 nautical miles. The convoy was made up of a large merchant vessel and three escorts. They are described as destroyers in the patrol report but they were not destroyers. The vessels were Ahrensburg on passage from Larvik to Fredrikshaven according to Rowher, escorted by T153, T155, F5, F8 and the minesweepers R33, R37 and R40

18:33 Tetrarch fired two torpedoes, range 4,000 yards, flat calm. Went deep and retired at high speed.

1837: Returned to periscope depth. Three escorting destroyers were seen approaching down the torpedo tracks a high speed. One of the destroyers was only 1500 yards away. Tetrarch went to 300 feet at full speed. Trim lost. Mills temporarily lost control and the boat dived to 400'

At 20:00 hours A/S trawlers joined in the hunt for Tetrarch

22:22 Surfaced, sighted two trawlers 1,000 yards away bearing down fast. Two torpedoes were fired. One one torpedo hit the UB boat. German sources indicate just three survivors.

Tetrarch was kept down at night and was therefore unable to charge batteries. Tetrarch eventually surfaced at 2130 hours on 24 April 1940 and set course back to Rosyth
20-05-1940 : HMS Tetrarch captures the Danish fishing vessel Emmanuel and sinks the Danish fishing vessel Terieven with scuttling charges in the North Sea west of Denmark.
16-06-1940 : HMS Tetrarch torpedoes and sinks the German tanker Samland south-west of Lista, Norway.
04-11-1940 : HMS Tetrarch torpedoes and sinks the Italian merchant Snia Amba off Benghazi, Libya.
12-04-1941 : HMS Tetrarch torpedoes and sinks the Italian tanker Persiano about 30 nautical miles north-west of Tripoli, Libya.
18-05-1941 : HMS Tetrarch torpedoes and sinks the Italian merchant Giovinezza off Bengasi, Libya.

27-09-1941 : HMS Tetrarch sinks the Greek sailing vessel Panagiotis Kramottos with gunfire south-west of Milos Island, Greece.
28-09-1941 : HMS Tetrarch torpedoes and damages the German merchant Yalova in the Aegean Sea south of Agios Giorgios Island.
27-11-1941 : HMS Tetrarch left Malta on 26th October 1941 bound for Gibraltar. The route she was to take meant her passing through a known minefield. On Monday 27th she communicated with P34 who was in the same area. This was the last contact with the submarine. It is believed that she struck a mine on 27th.
