Beginning with OA-179, the convoys of this route sailed from Methil instead of Southend and because of this change this convoy and the following convoy OA-180 were combined into one. Most of its ships had sailed from Southend to Methil in convoy FN-214 from 5 to 8 July. On 9 July, the convoy OA-180 then left with 31 ships in two columns to proceed into the North Atlantic around Scotland.
Shortly after 13.00 hours 10 July, the ships had only recently reformed in two columns after passing the Pentland Firth in a single line when Alwaki as second ship in the starboard column hauled out of line and stopped with an increasing list to port and subsequently foundered in the evening. As no explosion had taken place and neither the aircraft escorting the convoy nor an anti-submarine sweep by the escorts indicated the presence of a U-boat it was assumed by the Admiralty that her loss was the result of sabotage. In fact the convoy had passed almost directly over U-61 which fired a spread of two torpedoes at the ship from such a close distance that they weren’t armed yet when they hit the hull, but the flooding through the holes made by the torpedoes caused the ship to sink eventually.
The reminder of the voyage was uneventful, the convoy split on 11 July off Skerryvore with the coastal section proceeding unescorted through the North Channel while the ocean section of 19 ships continued westward. On 12 July, the corvette had to be detached and returned to port because she rolled badly in a moderate northerly gale. On 13 July, the convoy was dispersed in position 55°45N/17°20W and the destroyer returned to the Clyde.
