Warren Walker collection - RCN, RN, and other images - UPDATED

To follow up on an earlier post of photos from the collection of CPO Warren Walker showing flying operations from HMS BATTLER, I promised to display the remainder of the photos here. Warren's collection included a good number of photos of other ships of the Royal and Royal Canadian Navies, among others. 

I have elected to organize the photos loosely by the Navy being represented as well as the class of ship being displayed, and not in chronological order, as the latter is harder to determine.

Mr. Walker appears to have served in a number of RCN ships during his career, including (I believe) HMCS SAGUENAY in the 1930s, HMS BATTLER and HMS VINDEX in the summer of 1945, HMCS IROQUOIS, and HMCS ALGONQUIN and the weather ship HMCS ST. STEPHEN after the war. I have updated this post with Mr. Walker's service information, provided by his son Wayne, which appears at the bottom of this post.

Where available, I am providing the original captions as they appeared on the prints of each photograph, but only if I believe they are correct. I have also provided links to the Canadian Navy of Yesterday and Today site and Wikipedia where I believe appropriate.

A crew photograph from HMCS IROQUOIS, with Warren Walker on the far right of the front row.
Canadian Navy

In 1946, the RCN obtained its first aircraft carrier in the form of HMCS WARRIOR (formerly HMS WARRIOR), a light fleet carrier of the COLOSSUS-class. Although the RCN manned the escort carriers HMS NABOB and PUNCHER during the war, those ships were commissioned into the Royal Navy. WARRIOR served until 1948, after which the RCN traded her back to the RN in exchange for HMCS MAGNIFICENT.

Caption reads "HMCS WARRIOR coming out of dock". HMCS WARRIOR was the RCN's first aircraft carrier.
WARRIOR was not suited to service in Canadian climes, and the North Atlantic in particular, and she spent most of her time on the West Coast.

HMCS WARRIOR at sea.
As a result of her short career, there are not a large number of photos of her in RCN service.

HMCS WARRIOR approaching HMC Dockyard in Halifax, Nova Scotia. The carrier wharf was located under where the Macdonald Bridge was constructed.
Before the war, Mr. Walker served in a River-class destroyer, probably HMCS SAGUENAY. The River-class was a somewhat homogeneous class of Royal Navy destroyers of the C, D, E, F, G, and H sub-groupings, plus SAGUENAY and SKEENA which were built specifically for the RCN but which started off as essentially copies of the RN's A-class. Based on the captions and what little research I have been able to do myself, I believe the photos below were taken around the same time, many of them from the deck of SAGUENAY and featuring SKEENA. I believe that many of the photos were taken in the Caribbean, and SAGUENAY was assigned to Caribbean exercises in early 1939 so this fits. SAGUENAY lost her stern to a collision with a merchant ship on 15 November 1942, and she did not re-enter active service - so all photos here were taken prior to that event.


There was no caption on this image, but I'm assuming it was taken onboard an RCN ship - presumably SAGUENAY. At first I thought this was taken in Halifax, with the Halifax Shipyard in the background, but the far shore does not look right for Dartmouth.

"Some of the boys." Presumably taken at the same time as the above image, I was able to zoom in an identify the white line on the right as a breakwater - so definitely not Halifax. 

I'm assuming the ship in the background is HMCS SKEENA.

SKEENA wearing the pendant number D59. After 1940, she wore the number I59. This appears to be an abnormally calm sea.

Another photo of SKEENA wearing the D59 pendant. She appears to have a canopy rigged over the foc'st'le as well as the quarterdeck and the "B" and "X" gun mountings, suggesting the photo was taken in a warmer climate and the crew was trying to keep the sun from shining directly on the deck plates.

The caption reads "Cruise down river HMCS OTTAWA in distance."

Unnamed River class destroyer. 

Caption reads "SKEENA and part (port?) of Diamond Isle.

Three River-class destroyers rafted together. The outer two ships are SAGUENAY and SKEENA (not sure which is which) and the inner ship is a later vessel of the class - possibly OTTAWA. At far right is the bow of what I assume to be a cruiser, and there is a photo of a LEANDER-class cruiser below in the RN section to which I assume the bow belongs. 

A photo taken from SAGUENAY's foc'st'le, looking over at SKEENA - possibly taken at the same time as the image above, but before the canopy was rigged over the bridge. Positive ID can be made in this photo because both ships have the protrusion on the forward face of the bridge, and the ship on the right wears the badge of HMCS SKEENA (the small object in the middle of the bridge face). 

For reference, here is SKEENA's badge from www.georgeglazer.com

Looking aft under the starboard side lifeboat, probably onboard SAGUENAY, and the protrusion on the bridge suggests the trailing ship is SKEENA.


Two other River-class destroyers, possibly SKEENA and OTTAWA.



I believe this shot is taken looking aft from the bridge along SAGUENAY's starboard side. The gun beside the sailor's left shoulder appears to be a 40mm/39 (2-Pdr) Mk.II single anti-aircraft gun, which is consistent with the armament of a River-class destroyer up to 1942.

A 4" gun crew at work, probably on SAGUENAY. River-class destroyers mounted the 4.7"/45 QF Mk.IX gun on the Mk.CPXIV mounting.

HMCS ST. LAURENT (H83) alongside in HMC Dockyard with another River-class destroyer approaching in the background. ST. LAURENT arrived in Halifax from the west coast in September, 1939.

 HMCS ST. LAURENT (H83) with another River-class destroyer rafted up on the outside. The protrusion on the bridge of the outside ship suggests it is either SAGUENAY or SKEENA. It might be that this image was taken not too long after the image above, and the ship outside of ST. LAURENT is the same ship seen approaching the jetty in the image above.

HMCS SAGUENAY (D79) alongside at HMC Dockyard. SAGUENAY later wore the pendant I79.

SAGUENAY alongside to the left and another destroyer rafted outside of her, with a Royal Navy cruiser behind. Based on the twin funnels of equal height and the tall bridge superstructure, this would appear to be HMS YORK. YORK was transferred to Halifax in September 1939 upon the outbreak of the Second World War, so this may date this photo.

Looking aft along the port side of what I assume to be SAGUENAY.

Unidentified River-class destroyer (but not SAGUENAY or SKEENA based on the flat face of the bridge).

HMCS FRASER (H48) was sunk during the evacuation of France after being rammed by the cruiser HMS CALCUTTA. This is how she would have appeared before the war. I believe the two davits on the stern are for handling depth charges. 

This is the second HMCS OTTAWA (H31), which served the RCN from 1943 to 1945. Previously named HMS GRIFFIN, she was transferred to the RCN in March 1943 to replace the earlier OTTAWA which was sunk in September 1942. During the war, these ships were modified from the original configuration, and OTTAWA here is a good example: A-mount gun on the foc'st'le has been replaced with a large Hedgehog ASW mortar, B-mount carries illumination rocket rails on the gun shield, there is a Type 271 radar over the bridge, the aft funnel is cut down, and Y-mount is removed in favour of depth charge throwers. The forward torpedo tubes remain (behind the after funnel), but the aft set have been removed. 

A few of HMCS IROQUOIS:

A sailor stands under the guns of HMCS IROQUOIS (based on the artwork on the gun barrel muzzle covers).


And other ships:

The first HMCS PROVIDER. She served as a base supply ship for various flotillas of Fairmile motor launches during the war, both in the Caribbean and Canadian waters.
Due to a shortage of escorts, the RN and RCN were desperate for destroyers, and accepted a number of ex-USN four-stackers left over from the First World War.

HMCS ANNAPOLIS, one of the ex-USN destroyers provided to the British under the lend-lease agreement, and subsequently passed to the RCN. This appears to be a very early photo of her - not only has she not yet received the Type 271 radar, but she hasn't yet lost the aft (4th) funnel after she burned out her #4 boiler within a month of arriving in Halifax.
During the 1949/1950 period, Mr. Walker was assigned to the weather ship HMCS ST. STEPHEN for 30 day stretches, at which time the ship was assigned to the North Atlantic weather station, or "Baker" station, between Labrador and Greenland. ST. STEPHEN was modified from a River-class frigate

The weather ship HMCS ST. STEPHEN, possibly in St. John's, NL.
Both ST. STEPHEN, and STONE TOWN, were sold to the Department of Transport in 1950 and served in this role until approximately 1967. One book I have suggests STONE TOWN was not modified as a weather ship until after she was sold to the Department of Transport, but this photo clearly shows her still with the pendant 302, indicating she was still in the RCN. She also still has her gun.

HMCS STONE TOWN, also fitted as a weather ship, served on the West Coast in the Northern Pacific.

Preparing a weather balloon for launch from HMCS ST. STEPHEN. The triangular shape is a radar target, so that the ship can track the altitude of the balloon.
During the war, the RCN obtained two V-class destroyers, which were renamed ALGONQUIN and SIOUX in Canadian service. After the war, ALGONQUIN received a comprehensive refit into a "fast ASW frigate" similar to the Royal Navy's Type 15 frigates, and with some of the equipment to be fitted to the new ST. LAURENT class destroyer escorts that the RCN build in the early 1950s.

This photo shows the crew of ALGONQUIN sometime between her big refit and her paying off in 1970.
Royal Navy

There are several photos of the Royal Navy's "R" class battleships (sometimes noted as ROYAL SOVEREIGN- or REVENGE-class) in this collection. Completed during the First World War, at least two of this class - RAMILLIES and RESOLUTION - participated in convoy escort duty in the early parts of the Second World War. I am therefore assuming that these photos were indeed taken during the war, and during convoy escort operations.

RN "R" class battleship in what I assume to be Halifax Harbour.

"R" class battleship at sea. Later in the war the after mast appears to have been rebuilt to carry radar, reinforcing my assumption that these photos were at the latest taken during the early years of the war.

"R" class battleship at sea.

An "R" class battleship at sea, as seen from what I assume to be HMCS SAGUENAY.

Royal Navy Emerald class light cruiser - the class consisted of only two ships, EMERALD and ENTERPRISE, both of which were stationed in Halifax during the Second World War. This would appear to be ENTERPRISE, which received a prototype gun mount forward in the early 1930s, and as a result her bridge was rebuilt and moved forward.

The Royal Navy LEANDER-class cruiser HMS ORION. Caption reads "HMS ORION Sunday." ORION was assigned to the North America and West Indies station in 1937.

This is the cruiser whose bow appears in the previous image. The funnel gives it away as one of the Royal Navy's LEANDER-class of cruisers. The location is possibly Ireland Island, Bermuda. This may be another image of ORION, but I can't be sure.

Royal Navy light cruiser, probably Town class (Southampton group).

US Navy

There is unfortunately only one USN image in this collection:

The ship in the background looks like a USN battleship, and from comparing to my WWII edition of Jane's, I'm going to suggest that it may be a TEXAS class ship - either TEXAS or NEW YORK. I am also guessing the photo was taken during the 1930s.

Other

I have many resources to identify warships, but civilian ships often give me a hard time, so I resorted to crowd-sourcing the identification of the following two liners via Twitter. Within several hours, I had my answers, and Twitter users by the names of Robert Kirk and Jose Damota responded with the names of the two ships. After reviewing myself, I believe both ships are a close visual match for the names I am assigning to these images.

RMS Empress of Australia. According to "The River Class Destroyers of the Royal Canadian Navy" by Ken Macpherson, SAGUENAY and SKEENA met up with Empress of Australia on 15 May 1939, and escorted her and her passengers - the King and Queen - to Canada for a Royal Tour. This photo could have been taken at a few points during that tour.

S.S. Statendam with the bow of a warship to the right.

I don't where or when this was taken, but it doesn't look like a naval vessel to me.

I would once again like to thank Warren's son Wayne for sending me these photos and allowing me to display them here. Wayne was kind enough to allow me access to the original prints in his possession, and I was able to set them up to be copied with a high-resolution digital camera to get the most out of the prints.

Stadacona as Leading Telegrapher 1 Jan 1942 to 9 Mar 1943
HMCS Iroquois as Leading Telegrapher 10 Mar 1943 to 29 Mar 1944

Leading Telegrapher Warren St.Clair Walker, joined HMCS Iroquois, a new Tribal-class
Destroyer on 10 Mar 1943. He was the senior communications rating on board.
For most of June 1943, HMCS Iroquois was employed in the Western Approaches (to England),
escorting outward and inward Gibralter convoys. Then on 9 Jul 1943, the destroyers HMCS
Iroquois, HMS Douglas and HMS Moyola left Plymouth, England escorting the troopships SS
Duchess of York and SS California (carrying around 2,000 officers, men and crew) and the
ammunition ship Port Fairy to Freetown, Sierra Leone in Africa, in the high speed convoy “Faith”.
The SS Duchess of York was a liner owned by the Canadian Pacific Railway but re-commissioned
as a troopship by the British Admiralty.

Two days later, on 11 Jul, the convoy was 300 miles West of Vigo, Spain. It was a calm, cloud-
less evening. At 2035, a lone four engine German FW-200 aircraft appeared, circling the convoy 
but out of range. Half an hour later, two more arrived . The convoy was then attached by the
three Focke-Wulf Fw 200 aircraft based at Merignac near Bordeaux. The accurate high-altitude
bombing left both the SS Duchess of York and SS California blazing fiercely. At 2136 the aircraft 
made for the Port Fairy, but Iroquois’ 4 inch and anti-aircraft guns drove them off. Three minutes
later there was another attack but the bombs fell astern, then the German bombers returned to
their base. HMS Moyola and HMS Douglas began to take off survivors from the burning
troopships, their flames serving as a beacon for U-boats lurking in the darkness. HMCS Iroquois
conducted an anti-submarine sweep then closed with the SS Duchess of York to take off 628
men, including nine Czech officers. Canadian seaman dived overboard to rescue people struggling
in the water who had jumped from the burning ships. The escorts HMCS Iroquois, HMS Douglas
and HMS Moyola, together with the Port Fairy, rescued all but 27 from the SS Duchess of York.
Fearing the flames from the ships would attract U-boats the SS Duchess of York and the SS
California were sunk by the escorts at 0135. The Port Fairy was then escorted to Casablanca.
Morocco where the survivors were put ashore. The attacked cost the lives of 46 servicemen and
crew from the SS Duchess of York and SS California.

Highly censored newspaper accounts of the event, with HMCS Iroquois picking up the survivors,
called the ship’s crew action as “one of the outstanding rescues of the war, both from a standpoint
of its success and on heroism displayed.”

The plaque was presented to HMCS Iroquois in 1943, and was also mounted in the newer HMCS
Iroquois, DDH280. After the rescue, Captain Holmes of the Iroquois and two seamen were
presented the Czechoslovakian Military Cross for rescuing the nine Czech officers who were on
board the troopship.

Dad never spoke of this wartime action in which, as the senior communications rating on board
the Iroquois, he must have played an important role.

The Rest of the Story

Once HMCS Iroquois reached Casablanca, Morocco, the survivors were dis-embarked and she
was refueled and reprovisioned, everything had been eaten by the extra passengers. Instead of
going to Sierra Leone she was assigned to escort a convoy back to England. Aboard was a
German officer who had survived the sinking of U-506, sunk off Gibralter. Iroquois left the
convoy at Lands End and made for the naval base at Devonport, England to bring in the German
U-boat officer for interrogation by Naval Intelligence.

While returning to Devonport, the German officer’s jacket was taken at Captain Holm’s order to
be laundered. When the jacket was returned, the officer jokingly remarked that apparently
someone wanted a souvenir and had taken his U-boat officer insignia off the jacket. Capt. Holmes
became very agitated and gave an ultimatum over the PA system that the badge was to be
returned by 0800 or there would be no shore leave once the ship reached Devonport. A “ship’s
buzz” came around immediately after the ultimatum to the effect “if you have the badge, keep it.
To hell with Holmes”. The badge never showed up. Accordingly, all shore leave was stopped
when the ship reached Davenport.

The crew, mostly made up of young volunteers from across Canada, not accustomed to naval
discipline, especially Royal Navy discipline, took this very negatively. When ordered to sea on 19
July to escort another convoy, the lower deck hands, all Ordinary Seamen, refused to get up
steam and they shut down the ship. Leading Telegrapher Walker was locked in the communications area by the leaders of the “job action”. After negotiations with some very senior
shore-based naval officers, the Captain was relieved and taken ashore for medical reasons.
Shortly thereafter, HMCS Iroquois, and it’s Canadian crew, was re-deployed to Scapa Flow,
Scotland, (seen as a move to “punish” the ship’s crew for their un-Royal Navy like behavior.)
When the ship arrived in Scapa, Leading Seamen and below were mustered forward and blasted
by the Rear Admiral of Destroyers. Petty officers and above were mustered aft and blasted as
well. Capt. James Hibbard then joined HMCS Iroquois as her new Commanding Officer. The
defiance was never classed as a “mutiny” but as a “refusal for duty”. As a result, HMCS Iroquois
was assigned to Murmansk Convoy duty for six months.

(Dad had mentioned this little story to me and I had access, back in the early 1980's, I read over
the Secret Board of Inquiry file at the National Archives. It was subsequently declassified after 50
years, and a book was written about the incident.)

St. Hyacinth 30 Mar 1944 to 26 May 1944
Stadacona 27 May 1944 to 23 Mar 1945
HMCS Peregrine 24 Mar 1945 to 1 Apr 1945 (HMCS Pereguine was a land based ship in Halifax,
used as a training facility)

Once again, thank you to Wayne for providing this information, which provide useful background to the photos earlier in the post.

HMCS SACKVILLE Engine Room

Unlike today, where ships are typically powered by diesel or gas turbines, steam was the order of the day during the Second World War. Destroyers, cruisers, and battleships built during that time were fitted with steam turbines to provide better efficiency and higher speeds. Steam turbines are more expensive and are best fitted with gearboxes, so when it came time for emergency war-built convoy escorts - the Flower class, for instance - the Royal Navy decided to go with simple, reliable, triple expansion reciprocating steam engines. 

HMCS SACKVILLE.
A good example, and indeed the last of this particular powerplant in existence (though similar installations may exist in other museum ships), is the one in HMCS SACKVILLE on the Halifax waterfront. SACKVILLE is preserved by the Canadian Naval Memorial Trust (CNMT) as the world's last remaining Flower class corvette. I have photographed the interior of the engine room in SACKVILLE before, in 2002 and 2005, and wrote about it on the Hazegray and Underway website. Since that time, the engine room was allowed to deteriorate a bit, and it became quite dirty. More recently, former East Coast Fleet Chief ERA and CNMT trustee, Pat Devenish, has led an effort to clean up the engine room and return it somewhat to its former glory. Pat was kind enough to walk me through the engine room on Friday, so I could get a fresh set of photos for my records, and is responsible for many of the factoids that I recount in this post (though any errors are my own). 

Looking forward and to port, the cylinder tops are under the grey covers. Piston heads can be seen on the port wall over the engine. Everything has been scrubbed and repainted since I last set foot here. The blue plaque would not have been seen here during the war, but is apparently currently fitted within the engine rooms of HMC Ships.
The engine room has three levels, the highest being the catwalk on which I was standing to take the image above. Level 2 is on the catwalk visible at the bottom of the image, which brings you to the level of the cylinder heads and the original diesel generator and main switchboard. Below that, Level 1 brings you down to the propeller shaft and piston shafts. I'm not sure what the proper terminology is, but I hesitate to refer to them as decks.

Level 2

An original diesel generator, starboard side aft. The main switchboard is behind and to the right. The ladder descends from the catwalk over the aft end of the engine room. The genset's radiator is to the left of the photo.
The diesel generator provided electrical power for lights and other equipment requiring electricity, like radios and ASDIC (sonar). Diesel generators are still the method of choice for providing backup electrical power for modern facilities, with hospitals and sewage pumping stations as only two examples.

Close-up of the main switchboard, with what I assume is the generator's alternator in the foreground.
I doubt the electrical switchboard would meet modern safety standards, and the crew would have had to operate it in lively sea states in a type of ship that was itself known to be lively, and to "roll on wet grass". 

Looking aft from the port side, with the pistons to the right of the image. The ladder seen in the generator photo can be seen to the left of the image. The engine's condenser, which returned the steam to a liquid state before it returned to the boiler, is the grey object to the bottom right of the image. The catwalk at the rear of the photo is where visitors view the engine room from, as the rest of the space is not currently open to the general public.
The steam is first fed to the centre of the steam engine (when it is at its highest pressure), where the smallest of the four cylinders is located. The steam then passed to the mid-sized cylinder, and then to the two larger cylinders on the ends (when it is at its lowest pressure). A triple-expansion steam engine only needs three cylinders, but the final cylinder would have been too large for this installation, therefore it was split into two cylinders and SACKVILLE's engine has a total of four cylinders. Once the steam leaves the last cylinders, it passes to the condenser from where it returns to the boilers.

Ever wonder why railways were littered with water towers? Steam railway locomotives didn't have condensers, and needed to refill their tanks every once in a while. 

Another perspective of the engine room from the ladder in the forward port corner.

Looking forward and to port, the grey condenser is in the foreground. The pipes feeding into the top of the condenser come from the two cylinders on each end of the engine. Steam driven bilge pumps are in the background. I was standing on a Level 2 catwalk for this photo, looking down into Level 1.

Level 1

The steam driven bilge pumps seen in the background of the previous photo.

Not original to the engine room, the generator on the left provides ship's power during cold moves to and from the Dockyard and during memorial services off Point Pleasant Park on Battle of the Atlantic Sunday. On the right is the back end of the condenser. 

Looking aft along the starboard side of the engine. 

Looking into the engine from the starboard side. The connecting rods in the centre of the photo connect the piston rods above to the crank shaft at the bottom of the photo.

Looking forward at the row of piston and connecting rods through the engine.

Closeup of the connection between the piston rod above, the connecting rod, and the crank shaft below.

A view of the offset between the connecting rods from different cylinders - one is pushing down on the crank shaft, while the other rod is returned to top dead centre by the momentum of the shaft, ready for another power stroke. The piston rods traveled straight up and down, while the connecting rods are more dynamic in order to connect the piston rods to the rotating crank shaft. 
Where steam once powered the engine to turn the propeller shaft, SACKVILLE's propeller shaft is currently fitted with a hydraulic motor that when activated, turns the shaft and allows the engine to operate so that visitors can see it move.


Looking forward along the starboard side of the engine.

A closeup of the reversing engine and throttle handwheel.

Adjacent to the throttle handwheel is the engine room telegraph, which relayed orders from the wheelhouse.
Corvettes didn't exactly provide direct throttle control from the bridge to the engine room. Throttle settings and helm directions were relayed to the wheelhouse via voice pipe, one for each purpose (there was a voice pipe for the helmsman, one for the telegraph operator, and one for the throttle operator). And while the helmsman turned the wheel based on the direction from the bridge, another crewman listening to a separate voice pipe relayed throttle directions to the engine room via the telegraph, which in turn was registered on the telegraph in the photo above. With no less than 3 crew members involved in this chain, everyone had to be on their toes to ensure that throttle commands were relayed and obeyed in good order. Presumably this made coming alongside the jetty even more exciting than it is today.

Looking aft along the starboard side, showing the engine room telegraph opposite the throttle handwheel. The ladder back up to Level 2 is in the background.

This electrical distribution panel is located on the bulkhead at the aft end of the engine room. The ladder to the right accesses the "new" generator. Behind this bulkhead was the Engineer's Store.
Looking through my older set of photos, I see that the last time I stood in this location, I was the guest of former stoker Charles Dunbar. Charlie served in corvettes during the Second World War, and later went on to work for Foundation Maritime, where he joined Foundation Josephine in 1947.

Charlie Dunbar in the engine room in 2005, standing in front of the same electrical distribution panel as the photo above.
Ten years later, I was present to see Charlie's ashes piped over the side of HMCS HALIFAX off Point Pleasant Park.

The ashes of Charlie Dunbar are piped over the side of HMCS HALIFAX.
SACKVILLE is an old ship, and desperately needs some time out of the water for urgent hull maintenance to be performed. The hull plating is getting thin, and some of the frames themselves are also rotten and in need of replacement. The photo below shows the state of the hull plating when left on its own - it isn't possible to control the humidity within the ship, and bare metal rusts. In the case of the S.S. Great Britain, the ship is kept dry in the graving dock in which she was built and the entire hull below the waterline is encased with a glass roof, and a sophisticated de-humidification system slows the progress of oxidation. That isn't currently possible with SACKVILLE - but it might be, if Battle of Atlantic Place is ever constructed. 

The aft starboard quarter of the engine room is the one spot that hasn't received attention yet, so of course I had to take a photo. The rusted plate in the centre of the image is hull plating.
Rivets are supposed to be flush with the inside of the hull plating, and these rivets are proud of the plate, suggesting erosion of the plating. Eventually, the plate will thin to the point that it is no longer structurally sound, assuming some of it isn't already there. The necessary maintenance is tentatively scheduled for the winter of 2017/2018. 

The photographic quality isn't as good, but I provide a better description of the workings in the engine room on the Hazegray and Underway website.
