A document listing all the ON convoys states that ON 15 had a total of 40 ships – 2 British, 20 Norwegian, 6 Swedish, 3 Danish, 6 Finnish, 3 Estonian. 1 was not for Norway and was detached en route.

* The Norwegian Annfinn is said to have hit a submerged object off Rattray Head and sank in Norwegian waters, having been hove to in a gale. She was later salvaged. Jan-Olof Hendig, Sweden has sent me a newspaper clipping about this incident (from Febr. 28-1940), which states that she collided with a U-boat, whose periscope was torn off, and which, it is claimed, may have sunk. Arnfinn developed a heavy leak, but they managed to keep her afloat with the help of the pumps until they were off Holmgengrå, at which time they found it best to take to the boats, as they were standing in water up to their waists. They were in 2 boats, which were separated in the bad weather, one reaching Tangenes, while the men in the other boat were picked up by a Danish vessel and later taken to Bergen. Arnfinn is said to have been still afloat and drifting northwards, and a salvage vessel has been sent out. I’m not sure which ship this could have been – there was an Arnfinn Jarl, but I don’t have a ship named Arnfinn. The article states she was 950 tons and had a complement of 14. She was on a voyage from Methil to Moss with coal when the the incident took place.
** A. Hague lists Inger Toft as British, but I believe she was still Danish at this time.

All the Norwegian ships in this convoy, except Annfinn, are listed on this website – they can be reached via the Master Ship Index.
