Finally, on 22 September a Hais cable was laid that worked, delivering 56,000 imperial gallons (250,000 l) per day. This was followed on 29 September by the successful installation of a Hamel cable by HMS Conundrum 2.[40] However, on 3 October when the pressure was increased from 50 to 70 bars (730 to 1,020 psi) to augment the amount of fuel pumped,[39] both pipelines failed: the Hais due to a faulty coupling, and the Hamel when it encountered a sharp edge on the ocean floor.[40] Operation Bambi was terminated the following day. Only about 3,300 long tons (3,400 t) (935,000 imperial gallons (4,250,000 l)) of fuel had been transferred.[35][31]
