According to the subsequent interrogation of one of her survivors, she had a crew of only thirty-five as twelve were left behind when she sailed hurriedly. She also had a German Merchant Navy captain and an Italian Warrant Quarter Master as passengers. British Intelligence knew of both rendezvous and the cruisers HMNZS Leander and HMAS Canberra had sailed from Mauritius on 10 March and had been ordered to cruise the vicinity of 35° S, 50°00'E [yet O.I.C. reports it as 33° S, 50°'E] from 12th to 20th March, while the City of Durban (4,499 GRT, built 1921) would try to pass herself as the German supply ship (Operation SUPPLY). Leander refuelled at Mauritius on 20th March and resumed the search. The Vichy French Charles LD (5,267 GRT, built 1934) was intercepted and captured on 23rd March and the tanker Trocas, which was believed missing, was located on 27th March and escorted to Mauritius. In the South Atlantic, a similar operation was to be carried out by the British submarine HMS Severn, the sloops HMS Bridgewater, HMS Milford and the AMC HMS Alcantara. She reached Bordeaux after 13,100 miles and 81 days at sea. With Malaspina, escorted from Gironde Buoy no.1 to le Verdon by Sperrbrecher III. Then refit until September 1941.|

At 0218 hours, a pair of bow torpedoes (533mm, S.I. type) were fired at a range of 1,800 metres. The second torpedo veered right just after firing. Both missed. Immediately upon firing, Perla turned hard to port to present her stern and fired a third torpedo. The torpedo disappeared from sight shortly after firing and may have sunk or had an erratic run. T.V. Napp intended to continue the action with the gun,but an illuminated vessel, obviously neutral, came in between and thwarted this action, moreover, the target vessel was moving away at high speed. He have up the chase.
The target was the City of Pretoria (8,049 GRT, built 1937) travelling from Malta to Gibraltar. She heard two or three rapid shots followed by a dull explosion. She made smoke and dropped smoke floats, escaping into Spanish territorial waters.
