Three of the above listed ships sailed only on the 16th as convoy JW 53B and were to overtake and join the main convoy [see below].

On departure from Loch Ewe the convoy was escorted by the minesweeper HMS Jason (Cdr. H.G.A. Lewis, RN), corvettes HMS Bergamot (Lt. R.T. Horan, RNR), HMS Dianella (T/Lt. J.F. Tognola, RNR), HMS Poppy (Lt. N.K. Boyd, RNR) and the A/S trawlers HMS Lord Austin (T/Lt. E.L. Wathen, RNR) and HMS Lord Middleton (T/Lt. T.D. Bennett, RNR).

The escort destroyers escort destroyers HMS Meynell (Lt. B.M.D. I'Anson, RN), HMS Middleton (Lt. C.S. Battersby, RN), HMS Pytchley (Lt.Cdr. H. Unwin, DSC and Bar, RN) and minesweeper HMS Hazard (Lt.Cdr. L.C. Smith, RN) departed Scapa Flow on the same day and joined the convoy escort at sea. HMS Hazard however returned to Scapa Flow later the same day with weather damage and presumably never actually joined the convoy. She was replaced by HMS Halcyon (T/A/Lt.Cdr. H.L.D. Hoare, RNR) which departed Scapa Flow early on the 16th joining the convoy escort p.m. that day.

Also on the 16th convoy JW 53B, made up of three merchant ships of the above list, and escorted by the corvette HMS Bryony (T/Lt. T. Hand, RNR) departed Loch Ewe to overtake and join the convoy. The destroyers HMS Matchless (Lt.Cdr. J. Mowlam, DSO, RN) and HMS Musketeer (Cdr. E.N.V. Currey, DSC, RN) departed Scapa Flow to join convoy JW 53B which they did the following day after which HMS Bryony was detached to Liverpool as she had sustained weather damage. She arrived at Liverpool on the 18th.

On the 17th, the A/S trawler HMS Lord Middleton was detached with weather damage to Scapa Flow escorted by the corvette HMS Dianella. They arrived at Scapa Flow on the 18th.

On the 18th, one of the ships from convoy JW 53B was detached to Scapa Flow with weather damage. She was escorted by HMS Matchless. The merchant vessel eventually went back to Loch Ewe arriving there on the 22nd. HMS Matchless then went to Scapa Flow arriving there also on the 22nd.

On the 19th, the two remaining ships of convoy JW 53B also turned back, due to the weather conditions they were unable to overtake the main convoy. Three ships from the main convoy also turned back to Loch Ewe with weather damage. These five merchant vessels arrived back at Loch Ewe on 22 February. The destroyer HMS Musketeer proceeded to Akureyri, Iceland arriving there on the 20th.

On the 20th the destroyers HMS Milne (Capt. I.M.R. Campbell, RN), HMS Faulknor (Capt. A.K. Scott-Moncrieff, RN), HMS Boadicea (Lt.Cdr. F.C. Brodrick, RN), HMS Inglefield (Cdr. A.G. West, RN), HMS Obdurate (Lt.Cdr. C.E.L. Sclater, DSO, RN), HMS Obedient (Cdr. D.C. Kinloch, RN), HMS Opportune (Cdr. J. Lee-Barber, DSO and Bar, RN) and HMS Orwell (Lt.Cdr. J.M. Hodges, DSO, RN) departed Seidisfjord to join the escort of convoy JW 53 as did the corvettes HMS Bluebell (Lt. G.H. Walker, RNVR) and HMS Camellia (T/Lt. R.F.J. Maberley, RNVR). All these escorts joined the convoy p.m. 20th.

Also on the 20th the AA cruiser HMS Scylla (Capt. I.A.P. Macintyre, CBE, DSO, RN) and the destroyers HMS Fury (Lt.Cdr. C.H. Campbell, DSC and Bar, RN), HMS Eclipse (Lt.Cdr. E. Mack, DSO, DSC, RN), HMS Impulsive (Lt.Cdr. E.G. Roper, DSC, RN), HMS Intrepid (Cdr. W. Kitcat, RN) and ORP Orkan (Cdr. S. Hryniewiecki) departed Akureyri also to join the escort of convoy JW 53 which they did on 21 February.

On the 21st, HMS Middleton and HMS Pytchley were detached from the escort of convoy JW 53 to proceed to Seidisfjord where the arrived p.m. the same day. HMS Middleton was unable to anchor at Seidisfjord and the proceeded to Scapa Flow instead where she arrived on 23 February.

On the 22nd, HMS Meynell and HMS Halcyon parted company with convoy JW 53. HMS Meynell arrived at Seidisfjord p.m. on the 22nd, HMS Halcyon arrived the next day.

On 23 February the convoy was sighted and reported by German air reconnaissance and of the next day the convoy was being shadowed by aircraft and U-boats.

At 2142A/24, the German submarine U-622 attacked a destroyer with torpedoes. She missed but was later depth charged by the destroyer HMS Orwell which most likely had also been the target of her attack. The submarine escaped without damage though.

On 25 February the convoy was attacked around noon by 14 Ju.88's in position 73°41'N, 29°42'E. No damage was done to any ship in the convoy.

Around noon the 26th the convoy was attacked again from the air, in position 71°16'N, 36°54'E and again no damage was done.

Also on the 26th a Russian escort made up of the destroyers Gromkiy, Grozniy, Valerian Kyubishev and Uritsky joined as did the British minesweeper HMS Britomart (Lt.Cdr. S.S. Stammwitz, RN).

Later on the 26th, seven of the merchant vessels were detached to Archangelsk with the Russian escorts as well as the minesweeper HMS Britomart.

The bulk of the convoy arrived in the Kola Inlet on 27 February. The Archangelsk section arrived there the following day.


A battle force (distant cover force) for this convoy was also deployed. It departed Akureyri, Iceland on 22 February 1943 and was made up of the battleships HMS King George V (Capt. T.E. Halsey, DSO, RN, flying the flag of flying the flag of Admiral J.C. Tovey, KCB, KBE, DSO, RN, C-in-C Home Fleet), HMS Howe (Capt. C.H.L. Woodhouse, CB, RN), heavy cruiser HMS Berwick (Capt. G.H. Faulkner, DSC, RN) and the destroyers HMS Onslaught (Cdr. W.H. Selby, RN), HMS Offa (Cdr. R.A. Ewing, DSC, RN), HMS Musketeer, HMS Meteor (Lt.Cdr. D.J.B. Jewitt, RN), ORP Piorun (Cdr. T. Gorazdowski) and HMS Icarus (Lt.Cdr. E.N. Walmsley, DSC, RN).

They arrived in their covering position, 150 miles south-west of Bear Island on 24 February.

On the 26th the distant cover force returned to Akureyri except for HMS Berwick which was detached to Hvalfjord where she arrived on the 27th.


Besides the distant cover force there was also a cruiser / close cover force ' Force R '.

It was made up of the light cruiser HMS Belfast (Capt. F.R. Parham, RN, flying the flag of Rear-Admiral R.L. Burnett, CB, OBE, RN) and the heavy cruisers HMS Cumberland (Capt. A.H. Maxwell-Hyslop, AM, RN) and HMS Norfolk (Capt. E.G.H. Bellars, RN) departed Seidisfjord on 21 February.

' Force R ' arrived in the Kola Inlet on 26 February 1943.


A ' carrier ' force made up of the escort carrier HMS Dasher (Cdr. C.N. Lentaigne, DSO, RN) and the destroyer HMS Impulsive and the escort destroyers HMS Blankney (Cdr. P.F. Powlett, DSO and Bar, DSC, RN) and HMS Ledbury (Lt. D.R.N. Murdoch, RN) was also to be deployed from Seidisfjord but as HMS Dasher and HMS Blankney suffered weather damage in the built up stage of the convoy operation so the deployment of the ' carrier ' force was cancelled. HMS Impulsive then went to Akureyri to join the ' battle ' force instead. (3)
