  12 Jun 1940133631° 59'N, 29° 00'EAt 1336 hours, a convoy of pontoons escorted by a gunboat, were sighted steering 140° (toward Alexandria). Naiade opened fire at 1,800 metres, but broke off the attack due to wet ammunition and was forced to dive by machine-gun fire from the gunboat.

31° 42'N, 28° 50'EAt 2145 hours, a large tanker was sighted at a range of 4,000 metres, steering 130° at 13 knots. Naiade closed on the surface.

At 2157 hours, a torpedo (533mm) was fired from a bow tube at a distance of 1,200 metres. It hit and damaged the tanker.

This was the Norwegian tanker Orkanger (8,029 GRT, built 1928) carrying 10,500 tons of fuel oil from Port Said to Malta. The Italian declaration of war had forced her to turn back and she had been ordered to Alexandria.

Shortly after, the submarine reverted course and fired a stern torpedo (450mm) but it had an erratic course and missed. She reverted course again.

At 2218 hours, a third torpedo (450mm) was fired from a bow tube at 500 metres. It hit and the tanker sank. Survivors confirmed that two torpedoes had hit the engine room about ten minutes apart.

Four crew members were killed. Thirty-nine survivors (twenty-nine crew members and ten passengers, including Lt. Cdr. Crabbe, two stokers and nine military personnel) were picked up by the Spanish Tom who brought them back to Alexandria.

(e) 32° 03'N, 25° 56'E
T.V. Notarbartolo di Villarosa had intercepted Neghelli's signal or the torpedoing of a cruiser. Naiade was surfaced when an unidentified vessel was seen at a range of 1,500 metres, causing her to dive to 40 metres. She was straddled by four depth charges and damaged. The submarine tried to escape by going down to 125 metres.

At 1821C hours, the destroyers HMS Hereward and HMS Hyperion of the 2nd Flotilla were on A/S search for the submarine that had torpedoed the antiaircraft cruiser HMS Coventry the previous evening (this was Neghelli). HMS Hyperion obtained an ASDIC contact bearing 015° at 1,300 yards.

At 1825C hours, HMS Hyperion dropped four depth charges then lost contact but the submarine surfaced ten minutes later.

This was Naiade who immediately came under the combined gunfire of 4.7" gun and 0.5" machine-guns from both destroyers. Her crew abandoned ship, firing was checked and two whalers lowered from HMS Hyperion proceeded to pick up survivors. One rating was missing. Five officers and forty-one ratings survived and were sent to PoW camps.
