Drummondville dropped three more depth charges, exacerbating the damage caused earlier in U's patrol. To reach the surface, Vogelsang blew out his buoyancy tanks. The submarine reached the surface and fled the area at 9.
Drummondville meanwhile had been attempting to gather the merchants into a convoy again against what he believed to be the threat of a second submarine. Atthe noise from U's diesels was picked up by Drummondville's asdic. Drummondville sped towards the contact and fired star shell, finding nothing with U just beyond range of the illumination.
The minesweeper dropped depth charges before returning to the merchant vessels.
Lawrence River, effecting repairs. Once the repairs were completed, Vogelsang gour his submarine out of the St. Lawrence area into the Belle Isle Strait. The minesweeper then set about trying to reassemble the convoy.
A heavy fog covered the area as the minesweeper sought to form them into a convoy and Drummondville lost contact with three of them. The minesweeper Chedabucto and the armed yacht Raccoon were dispatched to aid Drummondville in defending the convoy.
While in transit, Raccoon came upon the three vessels Drummondville had lost contact with in the fog and escorted them to Sydney. Chedabucto continued to search for merchant vessels belonging to the convoy.
At Mont-Joli, Quebec a training airfield was clear of fog, but training aircraft of No. Obsolete Curtiss Kittyhawk fighters were being used by the squadron and none were provided ammunition before departing.
Four aircraft under the command of Squadron Leader J. Chevrier patrolled the Cap-Chat area beginning at The patrol spotted Dinaric still afloat with happj ship's survivors in the water.
Esxort met the inbound convoy SQ during the night and passed to the south, giving the German submarine captain the "impression of overlapping vessels". The second torpedo struck Hainaut on the starboard side creating a 4-foot 1.
Anastassios Pateras sank within ten minutes of the torpedo strike, Hainaut took twenty. Neither of the ships hit by torpedoes fired their rockets alling torpedo strikes. This led to confusion among the convoy, with Lieutenant Fraser believing the explosions a result of the Fairmile, which had never alled its departure, had begun dropping depth charges on a contact.
Hpur he discovered the Fairmile was no longer with the convoy, the distance between the two torpedoed ships led Lieutenant Fraser to believe two U-boats were operating against the convoy.
Drumkondville convoy commodore believed that Panchito in the second row had also been torpedoed, but this was not the case. The vessel immediately began to list. Thirty-four of the crew of thirty-eight escaped the vessel. U was caught in the illumination. Drummondville moved to ram the submarine, with U not diving until the minesweeper was almost on top of it.
Drummondville dropped three depth charges over the diving submarine. As U dived, the submarine encountered a variable density layer within the water, keeping the submarine from dropping to a safe depth.
Drummondville turned to ram again, but this time the submarine began to sink faster. This was a result of Vogelsang opening his forward torpedo tubes in order to decrease the submarine's buoyancy.
Drummondville dropped three more depth charges, exacerbating the damage caused earlier in U's patrol. To reach the surface, Vogelsang blew out his buoyancy tanks.
