HMS Cambrian: From Arctic Convoys to Quelling a Mutiny in East Africa

Laid Down as Spitfire, Commissioned as Cambrian

HMS Cambrian was built by Scotts Shipbuilding and Engineering at Greenock, her keel laid on 14 August 1942 under the name Spitfire, before being renamed and launched as HMS Cambrian on 10 December 1943, commissioning on 17 July 1944.

A C-class destroyer displacing 1,710 tons standard and up to 2,575 tons at deep load, she carried four 4.5-inch dual-purpose guns, a twin 40mm Bofors mount, six 20mm Oerlikon guns and two quadruple 21-inch torpedo tube mounts, a well-armed destroyer that joined the Home Fleet on commissioning, assigned to the 6th Destroyer Flotilla.

The yard that built her has a claim that no other British shipbuilder can match, and it deserves stating once. Scotts of Greenock was founded in 1711 by John Scott, a timber merchant, building small wooden sailing vessels for the local trade, and it is generally reckoned the oldest shipbuilding firm in the world. It bought a controlling interest in the neighbouring Caird and Company yard in 1861, which made it the dominant builder in Greenock, and by 1900 it was among the leading yards in Britain. When Cambrian's keel went down in August 1942, the family had been building ships on that stretch of the Clyde for two hundred and thirty-one years.

It ended the way the rest of them did. Scotts merged with Lithgows in 1967 to form Scott Lithgow, was nationalised into British Shipbuilders in 1977, closed the Greenock yard in 1984 and finally stopped trading in 1993. Two hundred and seventy years, and Cambrian was launched about seven-eighths of the way through it.

Arctic Convoys and the Far East

HMS Cambrian spent the final year of the war escorting Arctic convoys and supporting fleet operations off German-occupied Norway between 1944 and 1945, dangerous, cold-water work against a Kriegsmarine still capable of mounting serious opposition even as Germany's overall position collapsed.

After working up at Scapa Flow that summer, she spent October 1944 screening the fleet carrier HMS Implacable and the cruiser HMS Bellona alongside seven other destroyers while their aircraft struck the German-held airfields at Bardufoss and Sorreisa in northern Norway, part of the ongoing effort to keep the Luftwaffe off the Arctic convoy routes.

In November she escorted the liners Empress of Australia and Scythia to Murmansk and back, and in December joined a screen of thirteen destroyers covering convoy JW 62 out to the Kola Inlet, alongside her own 6th Destroyer Flotilla flotilla-mate HMS Cassandra. The return convoy, RA 62, turned deadly: on 11 December U-365 hit Cassandra with a torpedo that blew off her entire bow, killing 62 of her crew. One of Cassandra's ordinary seamen, Dudley Mills, later recalled the blast leaving "no fo'c'stle, no bows, no 'A' gun... just the sea foaming" in the light of the snowflake flares; she was towed, first by HMS Bahamas and then by a Soviet Navy tug, all the way back to the Kola Inlet. The following day a second escort, the Norwegian corvette Tunsberg Castle, was lost to a mine, and on 13 December the convoy's covering aircraft got their revenge, sinking U-365 with the loss of her entire crew.

She transferred for service in the Far East in June 1945, joining the East Indies Fleet at Trincomalee that August, arriving just as the war against Japan reached its conclusion.

Modernised for a Different Kind of Mission

The end of the war brought a long pause rather than retirement. Cambrian returned to the UK in May 1946 and paid off into reserve, and it would be the best part of two decades before she went to sea in anger again.

HMS Cambrian underwent modernisation in 1963, one of the last four of her class converted, receiving a new enclosed frigate-type bridge (differing from the design given to her earlier-converted sisters), an upgraded Mark 6M gunnery fire control system and two triple Squid anti-submarine mortars, changes that extended her useful service life well into the 1960s, a period in which the Royal Navy increasingly found itself called upon for exactly the kind of rapid-response colonial and post-colonial security work that would define HMS Cambrian's most notable later service.

Gunfire Support During the Tanganyika Mutiny

In January 1964, HMS Cambrian provided naval gunfire support off East Africa during operations connected with the mutiny of the Tanganyika Rifles, part of a wave of unrest that swept through several newly independent East African nations in the early months of 1964, prompting British intervention at the request of local governments, in this case President Julius Nyerere himself, to help restore order in the immediate aftermath of independence.

The 1st Battalion, Tanganyika Rifles had mutinied at Colito Barracks in Dar es Salaam on the night of 19/20 January, and within a day Nyerere was asking London for help. Cambrian and the commando carrier HMS Centaur, carrying 45 Commando Royal Marines under Lieutenant-Colonel Paddy Stevens, covered the roughly 2,500 miles from Aden to Dar es Salaam in just three days of intensive planning, a passage later remembered as a remarkably fast piece of improvised logistics. At dawn on 25 January, Cambrian opened the assault with a bombardment of the barracks before the Marines went in by helicopter, targeting the guardroom first as the focal point of the mutineers' resistance; the rest of the camp fell quickly once it was taken.

Cambrian's own commanding officer, David Hankinson, later wrote up the operation for the US Naval Institute's Proceedings journal, a rare case of a Royal Navy officer's account of a British colonial intervention reaching an American professional readership.

Tanganyika was not an isolated incident, and the wider picture makes the speed of the response easier to understand. Zanzibar had gone through a bloody revolution earlier that same month. Within the last week of January the armies of Tanganyika, Uganda and Kenya all mutinied in succession, and the grievances were much the same in each: pay, the slow promotion of African soldiers, and the fact that British officers were still commanding their units two years after independence. About 1,350 men of the Tanganyika Rifles took part, seized key points around Dar es Salaam and took the Defence Minister, Oscar Kambona, prisoner to deliver their demands. Nyerere in Tanganyika and Obote in Uganda both asked Britain to intervene, and by 27 January all three mutinies had been put down, with four mutineers killed.

It is an uncomfortable piece of history from every direction. Newly independent governments asked the former colonial power to send troops against their own armies, and the former colonial power obliged inside a week, using a commando carrier, a destroyer and 45 Commando. Cambrian's bombardment of Colito Barracks at dawn on 25 January was over quickly and cost very few lives, which is about the best that can be said of it. It was also the last kind of operation anybody had imagined for her when she was laid down on the Clyde in 1942 under the name Spitfire.

It was exactly the kind of politically delicate, rapid-deployment task that increasingly defined the postwar Royal Navy's role east of Suez.

A Final Deployment to Rodrigues

HMS Cambrian was deployed near Mauritius in January 1968, in the run-up to the island's independence that March, when she was diverted to the outlying island of Rodrigues after reports of an uprising. The "uprising" turned out to be a handful of islanders arrested for breaking into a government food store and helping themselves to a supply of sweet potatoes, having been left homeless and penniless by a cyclone that had torn through Rodrigues on Christmas Eve the previous month. Cambrian stood by off the island through the disturbances, joined on 22 January by the fleet tanker RFA Tidereach, a smaller and less well-remembered episode than Tanganyika but one that nonetheless demonstrated the same pattern of naval presence being used to keep the peace in Britain's remaining and former island territories in the Indian Ocean.

She was decommissioned in December 1968, her long service finally at an end, and sold for scrap to Thos. W. Ward in August 1971, arriving at the breaker's yard at Briton Ferry on 3 September that year, closing out a career that had carried her from the ice of the Arctic convoys to the considerably warmer waters of East Africa and the Indian Ocean.

There was a great deal more going on around Mauritius in January 1968 than a raid on a food store, and it is worth setting down because it is still being argued about in Parliament today. Mauritius was two months from independence. Three years earlier, in 1965, Britain had detached the Chagos Archipelago from the colony and constituted it as a separate territory, the British Indian Ocean Territory, which is very widely understood to have been the price of that independence. The point of the exercise was the largest island in the group, Diego Garcia, which the United States wanted for a base.

The islands were inhabited. Between 1968 and 1973, which is to say beginning in the very months Cambrian was steaming about that part of the Indian Ocean, the entire population of the archipelago, somewhere between fourteen hundred and seventeen hundred Chagossians, was removed. Most were put ashore in Mauritius and the Seychelles; a proportion of their descendants were eventually allowed to settle in Britain from 2002. They have been trying to go home ever since.

The argument reached a resolution of sorts within the last two years. On 3 October 2024 the British and Mauritian governments announced an agreement recognising Mauritian sovereignty over the whole archipelago, with Britain retaining the use of Diego Garcia for an initial ninety-nine years and resettlement permitted on the outer islands but not on the base. It took fifty-nine years. Cambrian's last operational deployment, remembered chiefly for a few men and a sack of sweet potatoes, took place in the opening weeks of all of it, and nobody aboard her would have had the first idea.
