Also taking passage in the convoy were the submarines HMS Trident (Lt. A.J.W. Pitt, DSO, RN), HMS Thrasher (Lt.Cdr. M.F.R. Ainslie, DSO, DSC, RN) and HMS Sea Scout (Lt. J.W. Kelly, RN) as well as 9 LCT's which were towed by some of the merchant vessels; These 9 LCT's were the following; HM LCT 480 (T/S.Lt. G.R. Sample, RNVR) which was being towed by the City of Lyons, HM LCT 488 (T/S.Lt. A.P.P. Thomas, RNVR) and HM LCT 489 (?) which were being towed by the Samfoyle, HM LCT 491 (T/Lt. W.C.

The convoy was escorted by and the sloop HMS Fowey (A/Lt.Cdr. G.E. Newey, RNR) and the corvettes HMS Allington Castle (A/Lt.Cdr. P.A. Read, RNR) and HMS Knaresborough Castle (T/A/Lt.Cdr. J.F. Marchant, RNR).

The convoy encountered poor weather and by the 17th it had even worsened. Some of the landing craft were now suffering from the weather conditions. Due to the extreme weather conditions the convoy hove to A.M. on the 18th and additional escorts were requisted.

Late in the afternoon of the 18th, HM 480 had to be abandoned by her crew due to the damage she had sustained and water she had shipped from the weather, loose cargo and defective welds. The crew was picked up from Carley floats around 2200A/18 by HMS Allington Castle. She sank to the south of Ireland around 2330A/18 after having been scuttled with gunfire.

HM 488 had sustained damage during the night of the 17th/18th. Around 1000A/18, she slipped her tow and got underway under her own power to try to make for Milford Haven. More and more water entered the landing craft and when a pump failed it became apparent that she most likely would go down. HMS Knaresborough Castle then closed and it was attempted to abandon the landing craft. Some of the crew was taken off but ten men remained on board during the night of 18/19 and tried to keep the ship afloat. By 0415A/19 the ship had to be abandoned as it was about to sink. Red flares were fired and HMS Knaresborough Castle closed. While doing so the landing craft sank and only one of the ten men on board could be picked up. The other nine, including the landing craft's Commanding Officer drowned.

HM LCT 491 got into trouble during the early afternoon of the 18th and as a result she slipped her tow as did HM LCT 7015. By mid afternoon of the 18th she had shipped a very heavy sea which damaged the welding around the door in the bow. More big seas followed and the ship was shipping a lot of water. Around 0100A/19, HMS Allington Castle closed. Around 0330A/19, HM LCT 491 started to sink. HMS Allington Castle went alongside and managed to take off the entire crew.

HM LCT 494 parted her tow around 0845A/18. She was last seen during the afternoon of that day while under her own power. She must have sunk in the evening with the loss of the entire crew.

HM LCT 7014 also slipped her tow in the morning of the 18th and got underway under her own power. By noon power had been lost and she sank not long afterwards. Part of her crew were picked up by the rescue ship, from convoy ON 260, Dundee (British, 1541 GRT, built 1934) but nine men, including the Commanding Officer lost their lives.

HM LCT 7015 also slipped her tow around 1500A/18. She was not seen afterwards and disappeared with her entire crew.

Meanwhile the frigates HMS Tobago (T/A/Lt.Cdr. J.H.L. May, OBE, RNVR) and HMS Zanzibar (T/Lt. F.F. Parker, RNVR) were ordered to detach from convoy HX 312 and join convoy OS 92 / KMS 66.

Three more escorts were also ordered to join, these were the escort destroyer HMS Blankney (Lt. B.H. Brown, RN) corvettes HMCS Huntsville (T/Lt. C.B. Hermann, RCNVR) and HMS Kingcup (T/Lt. T. Cooper, DSC, RNR).

Also on the 19th the City of Lyons parted company with the convoy due to damage sustained. She arrived at Milford Haven the following day.

P.M. on the 19th, HMS Kingcup reported proceeding to Falmouth with HM LCT 7022 and HM LCT 7023. Later the two landing craft were abandoned. HMS Kingcup took on board their crews and proceeded at best possible speed to Falmouth to land an injured men. The frigate HMS Drury (Lt.Cdr. N.J. Parker, RN) was ordered to stand by the two landing craft. Later HMS Kingcup returned with their crews and the landing craft were reboarded.

A.M. on the 20th found the convoy badly scattered.

P.M. on the 20th the Lagarto reported being in distress with weather damage and also having lost a men overboard. HMS Knaresborough Castle was also not in contact with the convoy. A signal was sent to requist more additional escorts. HMS Drury was then ordered to relieve HMS Allington Castle. Lagarto put into Falmouth.

A.M. on the 21st HMS Trident reported that a wire had fouled one of her propellers. HMS Knaresborough Castle was able to rejoin the convoy.

By P.M. on the 22nd, all ships had rejoined the convoy except four.

A.M. on the 23rd a signal was received from FOCNA (Flag Officer Commanding North Atlantic) that the Lisbon / Huelva section of the convoy was to part company on passing 39°N and proceed independently. They did so A.M. on the 24th.
