Rear-Admiral F.H.G. Dalrymple-Hamilton, CB, RN, commanding the 10th Cruiser Squadron, temporary transferred his flag from HMS Diadem (Capt. E.G.A. Clifford, RN) to HMS Bellona (Capt. C.F.W. Norris, DSO, RN). (13)

19 Nov 1944

Operation Handfast.

The object of this operation was to lay air laid mines in the Salhusstrommen, to the south of Haugesund and to attack enemy shipping if encountered.

Around 1700A/19, ' Force 3 ', made up of the light cruiser HMS Diadem (Capt. E.G.A. Clifford, RN, Senior Officer), escort carriers Premier (A/Capt. R.J. Gardner, RN), HMS Pursuer (A/Capt. H.R. Graham, DSO, DSC, RN) and the destroyers HMS Zealous (Cdr. R.F. Jessel, DSO, DSC and Bar, RN), HMS Onslaught (Cdr. The Hon. A. Pleydell-Bouverie, RN), HMS Scorpion (Cdr. C.W. McMullen, DSC, RN) and HMS Scourge (Lt.Cdr. G.I.M. Balfour, RN) departed Scapa Flow for the operation.

The force passed west of the Orkneys and south of the Shetlands before heading towards position 59°15'N, 01°10'E which was reached at 0849A/20. The strike was flown off at that time and consisted of 9 Avengers of 856 Squadron and also 16 Wildcats, 8 of each of the escort carriers. One Avenger however returned with ignition trouble. The strike sighted land at 1015A/20. This was believed to be Utsira Island but it later proved to be Stord Island which was well to the north so the strike had to alter course to the southward coming up of Rovaer Island and Karmo before altering up Karm Sund for the minelay. The defences were thus alterted and one Avenger received a hit from AA fire on the windscreen, injuring the eyes of the pilot and forcing him to break off and return to HMS Premier, jettisoning his mine set at 'safe' en route.

The remainder of the strike turned north over Avaldsnes and proceeded up the Sund in mining formation, laying their seven mines in approximately the pre-arranged position. The close escort fighters engaged shore batteries in the area of the lay, silencing them, and on completion rejoined the Avengers for return to Force 3. All aircraft were landed on by 1128A/20. In addition to the AA damage to the Avenger, 3 Wildcats from HMS Premier had received minor bullet damage from light AA fire.

Force 3 arrived back at Scapa Flow around 2205A/20. (42)

20 Nov 1944
Rear-Admiral F.H.G. Dalrymple-Hamilton, CB, RN, commanding the 10th Cruiser Squadron, transferred his flag from HMS Bellona (Capt. C.F.W. Norris, DSO, RN) to HMS Diadem (Capt. E.G.A. Clifford, RN) on this ships return from operation Handfast. (13)

21 Nov 1944
HMS Diadem (Capt. E.G.A. Clifford, RN, flying the flag of Vice-Admiral F.H.G. Dalrymple-Hamilton, KCB, RN) conducted exercises off Scapa Flow. (41)

22 Nov 1944
HMS Norfolk (Capt. J.G.Y. Loveband, RN) conducted exercises off Scapa Flow. These included a range and inclination (RIX) exercise with HMS Diadem (Capt. E.G.A. Clifford, RN, flying the flag of Vice-Admiral F.H.G. Dalrymple-Hamilton, KCB, RN) and a night encounter (NEX) exercises with HMS Zebra (Lt.Cdr. E.C. Peake, RN). (43)

24 Nov 1944
HMS Norfolk (Capt. J.G.Y. Loveband, RN) and HMS Diadem (Capt. E.G.A. Clifford, RN, flying the flag of Vice-Admiral F.H.G. Dalrymple-Hamilton, KCB, RN) conducted exercises off Scapa Flow. (43)

28 Nov 1944
HMS Volatile (Lt. F.R. Lawrence, RN) conducted A/S exercises at Scapa Flow with HMS Diadem (Capt. E.G.A. Clifford, RN, flying the flag of Vice-Admiral F.H.G. Dalrymple-Hamilton, KCB, RN) and HMS Orwell (Lt.Cdr. J.R. Gower, RN).

During these exercises HMS Volatile collided with HMS Orwell. Volatile sustained damage to her conning tower. The port side of the bridge was caved in. These was also heavy damage to both periscopes. One of which was completely carried away. (44)

6 Dec 1944

Operation Urbane.

The object of this operation was to conduct an anti-shipping raid in the area between Bergen and Stavanger and also lay air laid mines in this area.

Around 1605A/6, Vice-Admiral F.H.G. Dalrymple-Hamilton, KCB, RN, hoised his flag in the aircraft carrier HMS Implacable (Capt. C.C. Hughes-Hallett, RN) after having struck his flag in HMS Diadem (Capt. E.G.A. Clifford, RN).

Around 2300A/6, the force for this operation, made up of the aircraft carrier HMS Implacable (with Vice-Admiral F.H.G. Dalrymple-Hamilton, KCB, RN on board), escort carriers HMS Trumpeter (A/Capt. K.S. Colquhoun, RN), Premier (A/Capt. R.J. Gardner, RN), light cruiser HMS Diadem and the destroyers HMS Zealous (Cdr. R.F. Jessel, DSO, DSC and Bar, RN), HMS Zambesi (Lt.Cdr. W. Scott, DSC and Bar, RN), HMS Vigilant (Lt.Cdr. L.W.L. Argles, RN), HMCS Algonquin (Lt.Cdr. D.W. Piers, DSC, RCN), HMCS Sioux (A/Lt.Cdr. E.E.G. Boak, RCN), HNoMS Stord (Lt.Cdr. H. Øi), HMS Savage (Lt.Cdr. C.W. Malins, DSO, DSC and Bar, RN) and HMS Serapis (Lt.Cdr. E.L. Jones, DSC, RN) departed Scapa Flow.

The force then proceeded towards temporary position NN (59°15'N, 01°10'E) which was reached around 1030A/7. A dawn Mosquito reconnaissance along the coast between Bergen and Stavanger had found no suitable shipping targets for Implacable's strike aircraft, so it was decided to postpone that part of the operation and to continue with the minelaying mission on its own.

The mining strike, consisting of 12 Avengers of 856 and 846 Squadrons from HMS Premier and 14 Wildcats from HMS Trumpeter was flown off around 1230A/7. They were able to make a good landfall near Utsira Island and the strike split into various sections around 1345A/7. All 12 mines from the Avengers were seen to fall in their assigned positions close south of the Salhus lighthouse, but one mine was dropped at 'safe' and the parachute of another failed to open fully. During the lay the Wildcats attacked flak batteries and shore installations in the vicinity. On completion of the strike the aircraft set course to return to the escort carriers. During the return passage a Wildcat was seen to ditch in position 59°18'N, 03°20'E and the pilot was sighted in his dinghy, apparently unharmed. The ASR aircraft had already returned to its base with engine trouble and as the dinghy lay in a German minefield a destroyer could not be sent. Prolonged searches during the night and the following day proved fruitless and the pilot (T/Lt.(A) W.S. Vittle RNVR) was lost in unfortunate circumstances. The remaining aircraft were all flown in by 1510A/7. Four Wilcats and one Avenger were found to have been damaged by enemy AA fire.

The next day, 8 December 1944, after again receiving a negative report from the Mosquito reconnaissance, two reconnaissance strikes were flown off by HMS Indefatigable in an endeavour to locate and attack targets between Bergen and Stavanger. Two R-boats were attacked and set on fire during the second strike in the Bomlafjorden, R-59 was heavily damaged while R-56 later foundered after having burt out. After the aircraft had landed on the force set course to return to Scapa Flow where it arrived around 1050A/9. HMS Diadem had already arrived at Scapa Flow around 2045A/8 after having parted company with the force around 1555A/8.

On their return, Vice-Admiral F.H.G. Dalrymple-Hamilton, KCB, RN, transferred his flag back to HMS Diadem striking it in HMS Implacable. (45)

12 Dec 1944
HMS Diadem (Capt. E.G.A. Clifford, RN, flying the flag of Vice-Admiral F.H.G. Dalrymple-Hamilton, KCB, RN) and HMS Mauritius (Capt. C.A.E. Stanfield, RN) conducted exercises off Scapa Flow. (46)

13 Dec 1944
HMS Norfolk (Capt. J.G.Y. Loveband, RN) and HMS Newfoundland (Capt. R.W. Ravenhill, CBE, DSC, RN) conduced RIX (rangefinding and inclination) exercises off Scapa Flow.

Following these exercises HMS Newfoundland served as target during attack exercises by the submarine HMS Trusty (Lt. J.P. Fyfe, DSC, RN). These were carried out around noon.

Later in the afternoon aircraft made dummy attacs on HMS Newfoundland.

HMS Norfolk was meanwhile joined by HMS Diadem (Capt. E.G.A. Clifford, RN, flying the flag of Vice-Admiral F.H.G. Dalrymple-Hamilton, KCB, RN) and HMS Mauritius (Capt. C.A.E. Stanfield, RN) for more exercises.

Earlier in the day, HMS Mauritius had conducted turning trials. (47)

27 Jan 1945

Operation Halfback.

The object of this operation was to intercept three German destroyers proceeding from Norway to the Baltic.

Intercepted German signals showed that three of their large destroyers were to be redeployed from Norway to the Baltic.

To intercept them the light cruisers HMS Diadem (Capt. E.G.A. Clifford, RN, flying the flag and HMS Mauritius (Capt. C.A.E. Stanfield, RN) departed Scapa Flow around 1340A/27.

At 0015A/28, the enemy was detected to the west of the Sognefjord and at 0055A/28 the cruisers opened fire on the enemy. The leading destroyer, which was the Z 31 was hit at least seven times. Her forward turret was out of action and burnt out. The enemy returned fire one minute later and at 0106A/28, the two other enemy destroyers, which were the Z 34 and Z 38, fired torpedoes. The cruisers then had to comb the tracks to evade these torpedoes. The Germans retired towards the coast at high speed.

At 0127A/27, HMS Mauritius was hit on the port side forward on the messdeck near 'B' turret. There were no casualties.

At 0220A/27, the cruisers had to break off the action as the Germans had retired into the Aspo Fjord under the cover of coastal batteries. Course was set to return to Scapa Flow where the cruisers arrived around 1450A/28.

At 0133A/27, HMS Diadem was hit on the boat deck abaft the fore funnel and sustained some light damage but one crewmember was killed and three were wounded.
