On 4/ JUN/41 Esso Hamburg was found by cruiser HMS London, Destroyer HMS Brilliant. Crew scuttled her to avoid capture on position 07º 35’N 31º25’W
In conversation with an officer from "London" Captain Braunwarth described the scuttling of his ship. This, like all statements made by the Master, should be accepted with considerable reserve. Charges seem to have been placed aft, amidships and forward. In the engine room one large and one small charge were placed together along the ship's sides, the large one to blow a hole in the ship's side, and the small one to fracture the fuel pipes and cause fire.
In the pump room two large charges were placed one on each side of the sea valve boxes, which were stated to have been along the ship's side. Finally a large charge was placed on each side of the forward hold. All these charges were stated to be individually operated, a rating being sent to each position to press the igniting plunger. According to one of the stokers, two additional sea cocks had been fitted in the engine room to increase the rate of flooding.
Braunwarth stated that the scuttling charges had been set to detonate after twelve minutes, but actually did not explode until twenty-five minutes after firing, the fuses having been lit at the same time as she was observed to be lowering her boats. When boarded, by "Brilliant's" boarding party, she was already listing 35° to port, the port side being awash amidships.
"Brilliant" stated that the "Esso-Hamburg" carried two spare U-Boats' crews, but this statement has not been confirmed. "London" reported that although keeping watch on 500 kc/s and 12,700 kc/s no transmissions were heard.
