1939

Light cruiser HMS Gloucester: HMS Eagle (Capt. A.R.M. Bridge, RN), HMS Cornwall (Capt. C.F. Hammill, RN) and HMS Gloucester (Capt. F.R. Garside, CBE, RN) put to sea from Durban for the South Atlantic when it was reported that the German pocket battleship Admiral Graf Spee was in Montivideo harbour. They were recalled early the next day and they returned to Durban.

Submarine HMS Ursula: Ursula was on patrol off the Elbe estuary and through her periscope her Commanding Officer, Lt.Cdr. G.C. Phillips, RN, sighted a German light cruiser, escorted by six 'destroyers'. Though the waters of the Elbe estuary are shallow and to dive deep is a dangerous undertaking involving the risk of getting stuck on a sandbank, Phillips had either to take the risk or to miss his attack. His decision was instantaneous and he took the Ursula down to dive beneath the destroyer screen and get within range of the cruiser. They were anxious moments, but fortunately the depth of water was just enough. On coming up again to periscope depth, Phillips found himself within point-blank range of the cruiser. He fired a salvo of six torpedoes and the two resulting explosions were so close that the Ursula herself was badly shaken. A quick glance through the periscope showed no sign of the cruiser that had been attacked, but it did reveal four of her escorting destroyers closing in at high speed to attack. However one of the escorts, F 9, had been hit and was sinking. Once again, risking the sandbanks, the Ursula went deep and by skilful manipulation of his boat, Phillips managed to evade the inevitable depth charges. Of the cruiser, Leipzig, no further trace was seen, but when Phillips brought the Ursula back to look for evidence, two of the destroyers were still in the area and engaged, apparently, in a search for survivors. The British were under the impression they had sunk the cruiser and Lt.Cdr. Phillips was awarded the DSO and promoted. 1115 hours - Sighted a 'Koln-class' light cruiser escorted by six destroyers. Started attack. During the attack a Ursula had to go deep to evade one of the escorting destroyers. 1131 hours - Fired four torpedoes from 1200 yards. 1 min, 10 sec after firing a tremendous explosion occurred followed 6 seconds later by another even heavier explosion. This last explosion even broke some lights in Ursula. Four destroyers were gheard to come towards Ursula but no depth charges were dropped. Ursula managed to slip away from the scene. It was thought that the cruiser had been sunk but in reality one of the escorts had been hit by two of the torpedoes and was sunk with heavy loss of life. At the time F 9 was sunk she was part of the escort of the damaged Leipzig. Other escorts were; the destroyers Z 4 / Richard Beitzen, Z 8 / Bruno Heinemann, the escort vessel F 7, the minesweepers M 9, M 10, M 12 and M 13. Also in the area were the small minesweepers R 33, R 35, R 36, R 37, R 38 and R 39. R 36 and R 38 later picked up 34 survivors of F 9

Submarine HMS Rorqual: HMS Rorqual (Lt.Cdr. L.W. Napier, RN) attacked an enemy merchant vessel off Ischia Island. No hits were obtained. This was probably the Italian merchant Nino Padre (4171 GRT, built 1913) proceeding from Naples to Gaeta. (All times are zone -1) 1030 hours - Sighted a single unescorted merchant vessel coasting south of Ischia. Set course to intercept. The ship was an old one of 3000 tons, probably in ballast. 1101 hours - In position 279°, Imperatore Point, 4.2 nautical miles, fired three torpedoes from 4000 yards. Two violent explosions occurred 1 minute and 1 minute and 40 seconds after firing. These brought down glass and corking. It seems that two of the three torpedoes went straight to the bottom.

Submarine HMS Sahib: HMS P 212 (Lt. J.H. Bromage, DSC, RN) torpedoed and sank the Italian merchant Honestas (4960 GRT, built 1920) about 30 nautical miles north-north-west of Cape Bon, Tunisia in approximate position 37°29'N, 10°46'E. She was carrying 1000 tons of ammunition and 50 vehicles and was travelling from Trapani to Tunis in company with Castelverde (6666 GRT, built 1921), escorted by the torpedo boats Ardito and Fortunale and several aircraft including Ju 88 and Me 110. (All times are zone -1) 1215 hours - Sighted smoke and aircraft patrols bearing 030°. 1254 hours - Started an attack on 2 medium sized merchant vessels escorted by 2 Partenope-class torpedo boats. Several aircraft were patrolling overhead. Both torpedo boats were zigging in front of each of the merchant vessels. 1343 hours - One of the torpedo boats passed 1000 yards ahead. P 212 was not detected. 1350 hours - Fired 5 torpedoes at one of the merchant ships. It was hoped that the 5th torpedo might hit the other ship that partially overlapped with the target. One hit was obtained. After the attack P 212 went to 350 feet and retired to the Northward at 4 knots. 26 Depth charges were dropped in the next hour in patterns of 7, 7, 4 and 5 but none were really close and no damage was caused by them. HMS P 46 (Lt. J.S. Stevens, DSC, RN) meanwhile reported by SST that she had also attacked. That the other merchant ship had been her target, that it had changed course when our target had been hit and that this merchant had also been hit. 1538 hours - Returned to periscope depth. Noticed that both merchant ships were stopped in the vicinity of the attack. Our target was ablaze from the funnel to aft. Four aircraft were patrolling overhead and the escorting torpedo boats were to the Southward. Went deep again to reload the torpedo tubes. 1620 hours - Returned to periscope depth. Only one the merchants was seen, the other must have sunk. The escorts were still searching the area. 1648 hours - The other merchant vessel blew up with a terrific explosion so there was now no need to remain in the area to finish off the prey. According to Italian sources most of her crew were saved. The attack was observed by a R.S.14 of 144^ Squadriglia at 1346 which dropped two bombs but they do not appear to have been close. The other ship was the Italian freighter Castelverde and was indeed sunk by HMS P 46. Fortunale reported a sonar contact and was ordered to hunt the submarine while Ardito (her sonar was not working) picked up the survivors. Fortunale carried out four depth charges runs and then returned to pick up survivors from both ships. Ardito picked up 174 and Fortunale 96.

Submarine HMS Sibyl: HMS P 217 (Lt. E.J.D. Turner, DSC, RN) ended her 4th war patrol (2nd in the Mediterranean) at Algiers.

(All times are zone -1) 0945 hours - Sighted a floatplane in the expected direction of an enemy convoy. A few minutes later smoke was seen. Altered course towards. 1007 hours - Sighted a convoy made up of two medium-sized merchant ships escorted by two torpedo boats and several aircraft bearing 051 degrees. Started attack. 1114 hours - In approximate position 37°38'N, 11°02'E fired four torpedoes at the largest merchant ship. Range was 1000 yards. A hit and sinking was claimed but this was not the case as HMS P 212 (Lt. J.H. Bromage, DSC, RN) later attacked the same convoy. No counter attack followed on HMS P 228's attack. The convoy attacked was made up of the Italian merchant Honestas (4960 GRT, built 1920) and the Italian tanker Castelverde (6958 GRT, built 1921). The escorting torpedo boats were the Italian Ardito and Fortunale. They were on a trip from Trapani to Tunisia. Castelverde sighted three torpedo tracks while Ardito also avoided a torpedo. A few hours later Honestas and Castelverde were respectively sunk by HMS P 212 and HMS P 46.

Submarine HMS Trident: HMS Trident (Lt. P.E. Newstead, RN) conducted noise trials in Loch Goil.
