Here at LSOZI, we take off every Wednesday for a look at the old steam/diesel navies of the 1833-1954 period and will profile a different ship each week. These ships have a life, a tale all their own, which sometimes takes them to the strangest places. – Christopher Eger
Warship Wednesday, Oct. 4, 2023: Shipping Green

Above we see one of the 67 hardy River class frigates used by the Royal Canadian Navy, HMCS Swansea (K328), shipping green in January 1944 while off Bermuda. As acknowledged by Jane’s in 1946 about the class, following hard wartime service: “These ships have shown very good endurance and sea-keeping qualities.”
While the crew of Swansea— commissioned 80 years ago today– may have had something to say about that, the tough environment of the North Atlantic wasn’t enough to slow their business of slaying U-boats– and business was good.
The Rivers
While today the Royal Canadian Navy is often seen as a supporting actor in the North Atlantic and an occasional cameo performer elsewhere, by the end of World War II the RCN had grown from having about a dozen small tin cans to being the third-largest fleet in the world— and was comprised almost totally of destroyers, frigates, corvettes, and sloops! The force traded 24 of its warships in combat for a butcher’s bill that was balanced by 69 Axis vessels but had proved decisive in the Battle of the Atlantic.
One of the most important of the above Canadian ships was the River-class frigates. Originally some 1,800 tons and 301 feet in length, they could make 20-knots and carry a twin QF 4-inch gun in a single forward mount as well as a modicum of 20mm AAA guns and a wide array of sub-busting weaponry to include as many as 150 depth charges.

In addition to her twin 4″/45 forward, Rivers also carried six 20mm Oerlikons in two twin mounts — one seen here in a LAC Kodachrome of HMCS Thetford Mines– and two singles. Note the wavy lines on the Canadian lieutenant’s sleeve, denoting his status as a reserve officer. The running joke in Commonwealth Navies that used the practice was so that, when asked by an active officer why the braid was wavy, the reservist would answer, “Oh good heavens, so no one would mistake that this is my real job.”
Produced in five mildly different sub-classes, some 50 of the 150ish Rivers planned were to be made in Canada with others produced for the RCN in the UK. This resulted in a shipbuilding boom in the Land of the Great White North, with these frigates produced at four yards: Canadian Vickers in Montreal, Morton in Quebec City, Yarrow at Esquimalt, and Davie at Lauzon.

Meet Swansea
Ordered in October 1941 from Yarrows Ltd., Esquimalt, our little frigate remains the only vessel ever named for the Lake Ontario-facing Swansea neighborhood of Toronto, which until 1953 was an independent village. Yard No. 83 was laid down on 15 July 1942, launched almost exactly five months later, and commissioned on 4 October 1943.
Her skipper had already accounted for German U-boats a few times before.
Fifty-seven-year-old A/CDR Clarence Aubrey King, RCNR, DSC, DSO, had served in the British merchant service then switched to the Royal Naval Reserve in the Great War where he served in “Q-ships” and commanded one of those dreaded U-boat killers for the last 15 months of hostilities. During this time, he was credited with “one sure kill and two probables,” earning the Distinguished Service Cross in June 1917. Rejoining the colors with the RCN when WWII started, he commanded the corvette HMCS Oakville (K 178) in her battle with U-94 in August 1942 which ended with the latter’s destruction. This earned him the DSO.
Shipping out from Victoria, B.C., where Swansea was brought into service, her crew did their shakedown cruise to Halifax via the Panama Canal, arriving six weeks later on 16 November.
War!
Swansea clocked in for the Battle of the Atlantic right away. Her first convoy was SC 154 from Halifax to Liverpool in February-March 1944 and, briefly, the West-bound HX 281.
From there, she was detached to join Escort Group 9 at Londonderry, Northern Ireland. EG9 was all-Canadian, including the frigates HMCS Matane, Meon, Port Colborne, St. John, and Stormont in addition to Swansea.
Her first “kill” was a Type IXC/40 German submarine, U-845 (KrvKpt. Werner Weber) on 10 March 1944. In this action, south-west of Ireland, Swansea’s depth charges– joined with those from the British destroyer HMS Forester, the Canadian destroyer HMCS St. Laurent, and the Canadian corvette HMCS Owen Sound– sent U-845 to the bottom, with the group picking up 45 waterlogged survivors, KrvKpt. Weber not among them.
Then came U-448, a Type VIIC, sunk on 14 April 1944 north-east of the Azores by depth charges and naval gunfire from Swansea and the British sloop HMS Pelican, who afterward picked up 42 survivors.

U-448’s skipper, the Iron Cross-daubed Oblt. Helmut Dauter, was famously photographed walking off Pelican’s deck into captivity at Greenock, his war over.

Dauter, who earned the German Cross in Gold, would survive the war, and pass in 1987. The fact that the skipper and 41 of his crew lived through a four-hour-long creeping attack and 56 depth charges, with their boat’s batteries damaged and depth gauge broken, as well as a 6-inch hole in the after part of U-448’s pressure hull, then surfaced into heavy fire from both of the greyhounds that chased her down and were able to abandon ship to be recovered alive, was a small miracle.

Swansea’s third sub, U-311 (Kptlt. Joachim Zander), another Type VIIC, was sent to her eternal patrol on 22 April 1944 south of Iceland by depth charges from Swansea and her sister, HMCS Matane, with all hands lost.

22 April 1944, HMCS Swansea, commanded by A/Cdr Clarence A. King, DSO, DSC, RCNR, with HMCS Matane commanded by A/Cdr A. Frank C. Layard, DSO, RN, using depth charges, together sink U 311 south of Iceland. This was Commander King’s third submarine “kill” in 7 weeks. LAC photos
Then came another escort, that of Convoy OS 077KM, in May.
After that, she was detailed as part of EG9 to Operation Neptune, the naval component of Operation Overlord, the Normandy invasion.
HMCS Swansea was present on D-Day, assigned to Plymouth Command to cover the lift across the Channel, and for the next four months patrolled the Channel in support of the ships supplying the invasion forces, coming to the aid of downed Allied aircraft when she could.
It was in this mission that, on 1 September 1944 in the English Channel near Lands’ End, Swansea, and her sister HMCS Saint John, sent U-247 (Oblt. Gerhard Matschulat) to the bottom with all hands.
She rode shotgun on the tail end of HX 307 the next week, making sure it made Liverpool.
Swansea was also a lifesaver, and notably rescued seven men from an adrift Mulberry artificial harbor segment on 24 September.
November 1944 saw Swansea on outbound Convoy ON 264, sailing for Nova Scotia where she would be given a six-month refit and overhaul, where she was on VE Day.
Her crew marched in Halifax’s victory parade.
Ordered to work up for a Pacific deployment where she would lend her guns to the march on Tokyo, instead VJ Day found her in the Caribbean on post-refit shakedown.
Swansea was paid off on 2 November 1945 to reserve in Bedford Basin. She earned three Battle Honors (Atlantic 1943–44, Normandy 1944, English Channel 1944).

Jane’s 1946 entry on the 18 Canadian Rivers still in RCN service, noting all but one was in mothballs.
As for the legendary Capt. King, who had been on the bridge of Swansea for three of her U-boat kills and Operation Neptune, he would add a bar to his DSC and commanded the frigates HMCS Prince Rupert and Runnymede before moving to the Retired List in 1946. He crossed the bar in 1964 at Osoyoos, British Columbia, aged 77.
What of her sisters?
Of the 90 assorted Canadian River-class frigates ordered, a good number were canceled around the end of WWII. Four (HMCS Chebogue, HMCS Magog, HMCS Teme, and HMCS Valleyfield) were effectively lost to German U-boats during the conflict. Once VJ-Day came and went, those still under St George’s White Ensign soon went into reserve.
Several were subsequently sold for peanuts to overseas Allies looking to upgrade or otherwise build their fleets including Denmark, the Dominican Republic, Chile, Israel, Peru, and India.
Others were de-militarized and sold on the commercial market including one, HMCS Stormont, that became Aristotle Onassis’s famous yacht, Christina O. HMCS St. Lambert became a merchant ship under Panamanian and Greek flags before being lost off Rhodes in 1964. Still others became breakwaters, their hulls used to shelter others.
One, HMCS Stone Town, was disarmed and tasked as a weather ship in the North Pacific in the 1950s and 1960s.
But, Swansea still had some life left in her.
A different war
Swansea, by benefit of freshly refitting right before she was placed in reserve, was twice re-commissioned (12 April 1948-September 1949 and May 1951- 10 November 1953) for the purpose of training officer cadets and new recruits.
These periods saw her range as far north as Baffin Island and Godthab, Greenland, a three-week Caribbean training cruise, a Med cruise to the French Riveria, and Queen Elizabeth II’s Spithead review (34th in Line E).
She was paid off on 10 November 1953 and returned to storage once again.
Swansea was then selected to be rebuilt from 1956 to 1957, as a Prestonian class ocean escort with “FFE” pennant numbers, with our vessel becoming FFE-306. This conversion included a flush-decked configuration, an enlarged bridge, and a taller funnel. Deleted were the 20mm Oerlikons in favor of some 40mm Bofors. Further, they had their quarterdeck enclosed to accommodate two hulking Squid anti-submarine mortars in place of the myriad of depth charges/Hedgehog formerly carried. The sensor package was updated as well, to include ECM gear. One, HMCS Buckingham, was even given a helicopter deck.
Swansea recommissioned on 14 November 1957, ready to mix it up with Soviet subs if needed.

Seen in 1959, the Second World War frigate HMCS Swansea has been considerably modified to improve its anti-submarine capabilities. Although frigates like Swansea had been effective anti-submarine vessels during the Second World War, by the mid-1950s their weapons and equipment were of limited effectiveness against newer Soviet submarines. This photograph shows a number of the modifications made to Swansea between 1953 and 1957, including new guns and a bigger bridge for commanding and operating the ship (center). Other changes included the installation of two Squid anti-submarine mortars that replaced many of the ship’s depth charges. George Metcalf Archival Collection CWM 19780155-001
Swansea’s subsequent Cold War service was quiet, typically just involving assorted NATO exercises that ranged from Europe to the Caribbean.

She was paid off for a final time on 14 October 1966 and broken up in 1967 at Savona, Italy.
Epilogue
Little of Swansea remains.
A scale model of her is on display at the Canadian War Museum while a very detailed For Posterity’s Sake site exists chronicling the ship and her crew.
Most of the remaining Canadian Prestonian/Rivers were discarded alongside Swansea as the new St. Laurent– and Restigouche-class destroyers joined the fleet.
Two endured in auxiliary roles for a few more years: HMCS St. Catharines as a Canadian Coast Guard ship until 1968 and HMCS Victoriaville/Granby as a diving tender until 1973.
None of the Canadian-built ships were retained as museum ships, which is a shame.
In the end, two Canadian Rivers still exist, HMCS Stormont/yacht Christina O, and HMCS Hallowell/SLNS Gajabahu, with the latter a training ship in the Sri Lankan Navy until about 2016 and possibly still afloat.

Starting life in WWII as a Canadian Vickers-built River-class frigate HMCS Stormont, Christina O was purchased in 1954 by Greek shipping magnate Aristotle Onassis, who transformed her into the most luxurious private yacht of her time. She went on to host a wealth of illustrious guests, ranging from Marilyn Monroe and Frank Sinatra to JFK and Winston Churchill.
