1940

Heavy cruiser HMS Dorsetshire: HMS Dorsetshire (Capt. B.C.S. Martin, RN) departed Freetown for an anti-raider patrol in the mid-Atlantic. A signal had been received from the Admiralty that D/F bearings indicated that an enemy raider was most likely in an area bounded by lines joining (a) 15°N, 35W (b) 22°N, 32°W (c) 20°N, 30°W (d) 15°N, 32°W. For the daily positions of HMS Dorsetshire from 16 to 29 July 1940 see the map below.

Submarine HMS Oberon: HMS Oberon (Lt. C.B. Crouch, RN) arrived at Rothesay. She was now assigned to the 7th Submarine Flotilla for training purposes.

Submarine HMS Otway: HMS Otway (Lt. G.C.I.St.B.S. Watkins, RN) arrived at Rothesay. She was now assigned to the 7th Submarine Flotilla for training purposes. She was often used for the Commanding Officers Qualifying Course.

Submarine HMS Parthian: HMS Parthian (Lt.Cdr. R.D. Cayley, RN) departed Alexandria for her 5th war patrol (3rd in the Mediterranean). She was ordered to conduct a special operation and to patrol off the Kithera Channel. Later she was ordered to patrol off the east coast of Sicily. Before proceeding on patrol exercises were carried out with HMS Hasty (Lt.Cdr. L.R.K. Tyrwhitt, RN). For the daily and attack positions of HMS Parthian during this patrol see the map below.

Submarine HMS Phoenix: At 1252 hours (Rome time) HMS Phoenix (Lt.Cdr. G.H. Nowell, RN) possibly attacked the Italian tanker Dora C. (5843 GRT, built 1922) with torpedoes off Augusta, Sicily, Italy. The escorting Italian torpedo boat Albatros sighted 2 torpedoes. Albatros then possibly sank Phoenix during the counter attack in which a pattern of 10 depth charges was dropped followed by another pattern of 8. Albatros observed bubbles of air (no oil was seen) and believed that the submarine may have been damaged (it did not claim a sinking at the time). At the time of the attack Albatros was the only Italian vessel equipped with an experimental sonar but it broke down and was not used in the attack. So it is quite possible that she was sunk by Albatros on this day but is also possible that the torpedo tracks seen by Albatros were porpoises (a frequent mistake !). Phoenix was ordered to return to Malta on the 14th and she had acknowledged that she had received this signal. It is therefore a bit strange the she would still be in her patrol area around noon on the 16th. There was also an Italian minefield about 4 miles South-East of Augusta (minefield 4 AS) and although Phoenix had orders not to enter the 200 fathom line (an exception could be made if a target was worth it) so it is not impossible that she ran into it.

Submarine HMS Rainbow: HMS Rainbow (Lt.Cdr. L.P. Moore, RN) arrived at Alexandria.

Submarine HMS Clyde: HMS Clyde (Cdr. D.C. Ingram, RN) sank the Norwegian fishing vessel SF 52 (15 GRT) through ramming east of Alesund, Norway in position 62°19'N, 04°19'E. At 2230 hours a small fishing vessel was sighted and closed. Clyde was put alongside. The fishing vessel had a crew of four and were brought on board Clyde for interrogation. The fishing vessel was fitted for trawling but no trawl could be seen. The only fishing gear on board was a number of fish baskets. Also the hold was empty. Cdr. Ingram thought this to be suspicious and decided to sink the vessel and hold the crew on board.

(All times are zone -3) 0115 hours - While in position 220°, Cape Pappas (Nikaria), 10 nautical miles (about 37°22'N, 25°54'E), Tetrarch was attacked by what were thought to be two Motor Torpedo Boats. The Officer of the Watch altered course towards the first one sighted and when Lt.Cdr. Greenway sighted the second one he altered course towards this one and dived. Just before diving a torpedo track was seen to pass close astern. Tetrarch was most likely saved by the quick reaction of the Officer of the Watch. No depth charges were dropped and when Tetrarch came to periscope depth at 0500 hours nothing was in sight. Tetrarch had actually been attacked by the Italian submarine Nereide who fired two torpedoes from 700 metres and claimed one hit. The Italians give 37°25'N, 25°52'E as the position of the attack.

Both caused a short fire to break out as evidenced by a burst of flame and a large streamer of white smoke blowing to leeward. Believe one of these hits set off a ready ammunition box because of intensity suddeness, and briefness of smoke. Volume of target's fire was considerably reduced by these hits and from then on his movements became wild and erratic. Blenny stayed outside of the escorts range. 0748 hours - Ceased firing, out of 35 rounds only 2 hits had been obtained. 1030 hours - Now at the scene of the sinking.
