Warship Wednesday, July 3, 2024: Brace for Ramming

U.S. Navy photograph, 80-G-700007, now in the collections of the National Archives.

Above we see, just south-east of Halifax, Nova Scotia, the mine-filled shattered bow of the German Type XB U-boat, U-233, pointing to the sky just before plunging to the bottom after the submarine was rammed by the Cannon-class destroyer escort USS Thomas (DE 102) some 80 years ago this week– 5 July 1944. The unlucky U-233 was on her first combat patrol, tasked with sowing mines off key Canadian and American harbors.

She never made it that far and was one of Thomas’s three U-boat kills during the war.

And that was just in the destroyer escort’s first career.

What were the Cannons?

The Cannon class, ordered in 1942 to help stem the tide of the terrible U-boat menace in the Atlantic, was also known as the DET type from their Diesel Electric Tandem drive. The DET’s substitution for a turbo-electric propulsion plant was the primary difference from the predecessor Buckley (“TE”) class. The DET was in turn replaced with a direct drive diesel plant to yield the design of the successor Edsall (“FMR”) class.

Besides a heavy ASW armament, these humble ships carried a trio of Mk.22 3″/50s, some deck-mounted torpedo tubes to be effective against larger surface combatants in a pinch, and a smattering of Bofors/Oerlikon AAA mounts.

In all, although 116 Cannon-class destroyer escorts were planned, only 72 were completed. Some of her more well-known sisters included the USS Eldridge, the ship claimed to be a part of the infamous Philadelphia Experiment. The vessels were all cranked out in blocks by four yards with Thomas— along with class leaders Cannon and Bostwick— among the nine produced by Dravo.

Meet Thomas

Our subject was the second warship named for LT Clarence Crase Thomas (USNA 1908). A son of Grass Valley, California, Thomas served pre-war in the USS Maryland (ACR-8), USS Yorktown (PG-1), USS Denver (C-14), USS Cleveland (C-19), USS West Virginia (ACR-5), and battleship USS Florida. Once the U.S. entered the Great War, he was detailed to command the naval armed guard det on the merchant steamship SS Vacuum in April 1917.

Lost to a German U-boat just two weeks later, Thomas was the first U.S. naval officer to lose his life in the war with Germany and was posthumously awarded the Navy Cross.

His name was almost immediately issued to a Wickes-class destroyer (DD-182) then under construction, and sponsored by LT Thomas’s widow, Evelyn. That four-piper flush deck greyhound was decommissioned in 1922 and laid up until 1940, then transferred to the Royal Navy as part of the “bases for destroyers” deal, becoming first the Town-class destroyer, HMS St Albans (I15), then the Free Norwegian Navy’s HNoMS St Albans, and finally the Soviet destroyer Dostoyny/Dostojnyj before being scrapped in 1949.

Meanwhile, our subject, the second Thomas, DE-102, was laid down on 16 January 1943 by Dravo and commissioned on 21 November 1943 at Portsmouth, her build time spanning just 310 days.

War!

Assigned to Escort Division 48 as flagship, she was surrounded by five sisters– USS Bostwick, Breeman, Bronstein, Baker, and Coffman. Her shakedown took place off the East Coast and she spent the Christmas 1943/New Year’s 1944 holiday in Bermuda.

Her first bite at Dönitz’s grey sharks came as part of the hunter-killer group attached to the jeep carrier USS Block Island (CVE-21) for six weeks in February-March 1944. This included the 1 March 1944 kill north of the Azores of a submarine credited by the Navy as the Type VIIC U-boat U-709 (Oblt. (R) Rudolf Ites), sunk with all hands. Alternatively, some reports hold this was actually U-441, which was severely damaged but escaped.

Then came a stint riding shotgun on Convoy UGS 39 and its return (GUS 39) from the U.S. to the Med.

Then came more hunter-killer taskings.

USS Thomas was taken on 5 July 1944 from the escort carrier USS Card (CVE-11). 80-G-366262

On 5 July 1944, sisters Thomas (DE-102) and USS Baker (DE-190), from the jeep carrier USS Card’s hunter-killer force (Task Group 22.5), ran U-233 (Kptlt. Hans Steen) to ground off Halifax, Nova Scotia. The action began at 1910 when Baker picked up a sound contact at 1,500 yards.

Just 17 minutes and two depth charge patterns later, a submarine’s bow broke the surface and Baker took the enemy boat under surface fire, with Thomas closing in and opening up with her deck guns shortly after. The end came when Thomas rammed the shell-riddled U-boat on its starboard side just aft of the fairweather. By 1947 it was all over and the tin cans were plucking survivors from the water.

From the 12-page report filed by LCDR David M. Kellog, Thomas’s skipper:

A great series of shots captured from Thomas show the last dive of U-233.

80-G-700005

Thomas picked up 20 of U-233’s 69-man crew, including Kptlt. Steen, who later died of wounds. The survivors, along with two Enigma coding wheels recovered from the pockets of one of the men, were transferred to Card.

Interrogations later revealed U-233’s mission and her cargo of 66 new type Drückunterschiedsmine (pressure differential mines) along with four T-5 and three G7e torpedoes, none of which the boat had a chance to use.

As far as Thomas was concerned, she suffered only minor damage from her ramming kill, chiefly in two flooded peak tanks and a leaking chain locker. Proceeding to Boston Navy Yard for repairs, she was back on duty by 18 July and spent the next six weeks shepherding new submarines out of Portsmouth and Groton undergoing shakedown in Long Island Sound.

September 1944 found her back with the Card hunter-killer group, surviving hurricane-force winds at least twice at sea before the end of the year as the task group roamed the stormy North Atlantic.

She would continue to serve with the Card group into 1945, alternating going to the rescue of sinking ships and chasing down sonar contacts. On 30 April 1945, Thomas, along with the frigate Natchez (PF-2), and sisterships Coffman and Bostwick, came across what is cited by the Navy as the advanced Type IXC/40 U-boat U-548 just east of Cape Hatteras but is now generally believed to be sister U-879 (Kptlt. Erwin Manchen), sending her to the bottom with all 52 hands.

Post VE-Day, Thomas would spend the next four months in a series of exercises before she was detailed to New York to take part in the massive Navy Day celebrations there and in November was tasked to escort the infamous Type IXC/40 U-boat U-530 (Oblt. Otto Wermuth), which had surrendered in Argentina two months after the end of the war in Europe.

Following a series of war bond tours with Thomas and U-530, the latter was utilized for a series of tests and deep-sixed in torpedo drills off Cape Cod.

However, by that time, Thomas had been decommissioned at Green Cove Springs, Florida, in March 1946 and added to the 500-strong mothball fleet that swayed at a series of 13 piers built there just for the purpose.

She was not even listed in that year’s Jane’s Fighting Ships entry for her class.

Thomas received four battle stars for World War II service.

Plank owner LCDR Kellogg, who earned the Legion of Merit for the U-233 ramming and commanded the vessel throughout the war, faded into history and I cannot find any further information on him.

A long second life

While Thomas’s initial service would last just three years, others could desperately put the low-mileage destroyer escort to good use.

Ultimately 14 of the Cannon/Bostwick class went to France and Brazil during the war, followed by another eight to the French– who apparently really liked the type– four to Greece (including USS Slater which returned home in the 1990s to become the only destroyer escort afloat in the United States), three to Italy, two to Japan, six to the Dutch, three to Peru, five to the Philippines, two to South Korea, one to Thailand, and two to Uruguay.

When it comes to Thomas, she and three sisters: Bostwick, Breeman, and Carter, in a short ceremony on 14 December 1948, were transferred to Nationalist (Chiang Kai-shek’s KMT) China. Thomas became class leader Taihe (also seen in the West as ROCS Tai He and ROCS Tai Ho) with the hull/pennant number DE-23.

The four destroyer escorts were soon put into emergency use. During the last phase of the Chinese Civil War in 1949, the 26 loyal ships of the ROCN engaged in the protection of supply convoys and the withdrawal of the Nationalist government and over 1 million refugees to Taiwan.

These ships were captured in great detail during this period in Nationalist use by LIFE magazine.

The No. 3 mount now has an additional 3″/50 rather than the 40mm Bofors. Also, that is A LOT of depth charges for those 8 throwers and two rails! Ash cans a-go-go

Needing bigger guns for the work envisioned of them, the Chinese quickly upgraded their two forward 3-inchers to a pair of 5″/38 singles in open mounts, as well as substituting the stern 40mm mount for one of the same which gave the ships a 2+2 format with twin 5-inchers over the bow and a 5-inch over a 3-inch over the stern. 

The 1950s saw the fleet heavily involved in the pitched and tense engagements around Kinmen (Quemoy), Matsu, and the Yijiangshan and Dachen Islands in the Taiwan Straits as well as the clandestine Guoguang operations in which the KMT tried to retake the mainland by landing would-be guerilla organization teams in Red territory.

Taihe notably took part in the Battle of Pingtan Island in August 1949, covered the retreat from Hainan Island in April 1950, the Battle of the Wanshan Islands in May 1950 (where she is credited with sinking the gunboat Jiefang and the LCI Guishan), the running Battle of the Tohoku Islands where she escaped a trap set by six Red corvettes and frigates, damaging the Changsha (216)– formerly the Japanese Type D coastal defense ship No. 118– in the process; rescuing the torpedoed destroyer Taiping (DE-22, ex USS Decker DE-47) during the Battle of Yijiangshan Island in November 1954, and conducting a series of tense patrols in the Spratly Islands in 1956.

In all, Thomas and her three sisters continued to hold the front lines of the Taiwan Straits for 25 years and, for the first decade of that, were the most powerful assets available to the ROCN, a title they held until two Benson-class destroyers (USS Benson and USS Hilary P. Jones) were transferred in 1954.

They were also later fitted in the 1960s with Mk.32 12.75-inch ASW torpedo tubes for Mk 44s– which were a lot more effective than depth charges.

As part of the pressure on Communist China at the tail end of the U.S. involvement in Vietnam, the Nixon administration transferred a huge flotilla of more advanced warships to Taiwan between late 1970 and early 1973 that included two GUPPY’d Tench-class submarines (one of which is still active), five Gearing-class destroyers, six Sumner-class destroyers, four Fletchers, and USS McComb (DD-458)— a late Gleaves-class destroyer that had been converted to a fast minesweeper. With all these “new-to-you” hulls, the long-serving destroyer escorts could be retired and, by the end of 1973, Thomas and her three sisters in Formosan service had been disposed of for scrap. 

Epilogue

Few relics remain of Thomas in the U.S. Her war history and diaries are in the National Archives.

A painting of Thomas ramming U-233 by maritime artist John G. Gromosiak of Cincinnati is in the U.S. Naval Museum at Annapolis but I can only find this small image of it, via Navsource.

The U.S. Navy has yet to recycle LT Thomas’s name for a third vessel, which is a shame.

Besides the museum ship USS Slater (DE-766), now sitting dockside in Albany New York, and the pier side training ship USS Hemminger (DE-746) (now HTMS Pin Klao DE-1) in Thailand, there are no Cannon-class destroyer escorts still afloat.

USS Slater is the only destroyer escort preserved in North America– and is Thomas’s sistership

The Destroyer Escort Sailors Association honors the men of all the DEs, regardless of class. Sadly, their 45th annual convention in 2020 was their last as their numbers are rapidly declining.

Ships are more than steel
and wood
And heart of burning coal,
For those who sail upon
them know
That some ships have a
soul.

Warship Wednesday, March 8, 2023: USS FBI

Official U.S. Navy Photograph, from the collections of the Naval History and Heritage Command. Catalog #: NH 106576

Above we see the Bogue-class escort carrier USS Block Island (CVE-21), photographed from a blimp of squadron ZP-14 underway on her first ASW hunter-killer cruise, seen off the mouth of Chesapeake Bay on 15 October 1943. Arranged on her flight deck are a dozen TBF/TBM Avenger torpedo planes and nine F4F/FM Wildcat fighters of Fleet Composite Squadron 1 (VC-1) — big medicine for such a small flattop. Commissioned just six months prior on 8 March 1943– 80 years ago today– Block Island would have a bright if an unsung career in the Battle of the Atlantic, although she would not live to see it conclude.

About the Bogues

With both Great Britain and the U.S. running desperately short of flattops in the first half of World War II, and large, fast fleet carriers taking a while to crank out, a subspecies of light and “escort” carriers, the first created from the hulls of cruisers, the second from the hulls of merchant freighters, were produced in large numbers to put a few aircraft over every convoy and beach in the Atlantic and Pacific.

Of the more than 122 escort carriers produced in the U.S. for use by her and her Allies, some 45 were of the Bogue class. Based on the Maritime Commission’s Type C3-S-A1 cargo ship hull, these were built in short order at Seattle-Tacoma Shipbuilding Corporation, Ingalls Shipbuilding in Pascagoula, and by the Western Pipe and Steel Company of San Francisco.

Some 496 feet overall with a 439-foot flight deck, these 16,200-ton ships could only steam at a pokey 16 ish knots sustained speed, which negated their use in fleet operations but allowed them to more than keep up with convoys of troop ships and war supplies. Capable of limited self-defense with four twin Bofors and up to 35 20mm Oerlikons for AAA as well as a pair of 5-inch guns for defense against small boats, they could carry as many as 28 operational aircraft in composite air wings. They were equipped with two elevators, Mk 4 arresting gear, and a hydraulic catapult.

Most of the Bogue class (34 of 45) went right over to the Royal Navy via Lend-Lease, where they were known as the Ameer, Attacker, Ruler, or Smiter class in turn, depending on their arrangement. However, the U.S. Navy did keep 11 of the class for themselves (USS Bogue, Card, Copahee, Core, Nassau, Altamaha, Barnes, Breton, Croatan, Prince William, and our very own Block Island), all entering service between September 1942 and June 1943.

Meet Block Island

Oddly enough, our little carrier was not the first named after the sound that lies east of Long Island, N.Y. and south of Rhode Island. The Navy ordered an early Bouge class aircraft escort vessel, AVG-8, under a Maritime Commission contract (M.C. Hull 161) on 12 May 1941 at Ingalls in Pascagoula, and issued her the name USS Block Island on 3 February 1942. However, the name was canceled the following month as the hull was allocated to the Royal Navy who in turn would launch her as HMS Trailer, then HMS Hunter (D 80), and bring her into service under Admiralty orders in January 1943.

HMS Trailer, ex-USS Block Island (ACV-8), later HMS Hunter (D80), location unknown, 14 January 1943, likely in the Gulf of Mexico. Via ONI Division of Naval Intelligence, Identification and Characteristics Section, June 1943.

Our subject, the second Block Island, the first to see commissioned U.S. Navy service, was AVG-21, M.C. Hull 237, laid down on the other side of the country at the Seattle-Tacoma Shipbuilding Corporation Yard on 19 January 1942. She was named USS Block Island on 19 March 1942– the same day the Pascagoula Block Island had her name canceled, then was reclassified as an auxiliary aircraft carrier (ACV-21) and subsequently commissioned on 8 March 1943. As such, she was the eighth of 11 Bogues brought into U.S. service.

Her first skipper, Capt. Logan Carlisle Ramsey (USNA 1919), had made his spot in history already when, on the staff of PATWINGTWO at Ford Island on 7 December 1941, had ordered the famous “Air Raid Pearl Harbor! This is No Drill!” flash message.

Shuttle work

Soon after delivery and an abbreviated shakedown, the new carrier was rushed to the Atlantic where she was urgently needed to tackle the persistent U-boat threat. Picking up the Wildcats and Avengers of Composite Squadron (VC) 25 in San Diego in April, she would arrive in Norfolk via the Panama Canal in early June, where VC-25 would go ashore.

Sailing for Staten Island in July, she took aboard deck and hangar cargo in the form of brand new USAAF P-47D-5 Thunderbolts and rushed them, partially disassembled, to Belfast.

Getting in the Hunt

Upon reaching Norfolk after her second Jug run, Block Island got called up to the majors and, with squadron VC-1 embarked, spent a month in practice runs before shoving out into the Atlantic on 15 October as the centerpiece of Task Group (TG) 21.16, augmented by four destroyers. As an ace in the hole, the group was bird dogged by Ultra Intelligence from decoded German Enigma ciphers.

Although her group caught and damaged the big “milch cow,” U-488, then harassed U-256, and bagged U-222 (Oblt. Bruno Barber) on 28 October 1943, sent to Poseidon by Mk. 47 depth bombs from two of VC-1’s Avengers. U-220, a minelayer boat returning from laying her evil eggs off Newfoundland, went down with all hands.

Exchanging VC-1 for VC-58– the latter’s Avengers now equipped with the new 5-inch HVAR “Holy Moses” rockets– Block Island‘s planes soon chased U-758 in January 1944 on her second hunter-killer cruise but again did not sink her. In the attack 11 January attack, the HVAR was used against a submarine for the first time.

TBF aircraft, (VC-58), from USS Block Island (CVE 21) make the first aircraft rocket attack on a German submarine, U-758, on January 11, 1944. The submarine survived the attack and returned to St. Nazaire, France, on 20 January. In March 1945, it was stricken by the German Navy after being damaged by British bombers at Kiel, Germany.

Her habit of being quick to attack reported U-boats earned her the nickname, “USS FBI” for “Fighting Block Island.”

This would be taken to even greater proportions by her second skipper, Capt. Francis Massie (“Frank”) Hughes (USNA 1923), a tough Alabaman who, like Block Island’s first skipper, had been at Pearl Harbor. During the December 7th attack, Hughes was the first Navy aviator who managed to get his aircraft in the air and did so while still in his pajamas, then later flew during the Battle of Midway.

On 1 March 1944, the Canon-class destroyer escort USS Bronstein (DE 189), part of Block Island’s T.G., reported a depth charge attack that has sometimes been credited as being a kill against U-603 (Kptlt. Hans-Joachim Bertelsmann) which had gone missing about that time.

On 1 March, Block Island‘s trio of destroyer escorts– USS Thomas, USS Bostwick, and Bronstein— depth-charged an unidentified submarine north of the Azores. This is typically thought to be U-709 (Oblt. (R) Rudolf Ites) which was reported missing in the same general area around that time and has never been found.

On 17 March, her aircraft, teaming up with the destroyer USS Corry and Bronstein, sank U-801 (Kptlt. Hans-Joachim Brans) west of Cabo Verde Islands. In that action, a new Fido homing torpedo dropped by an Avenger carried the day. Corry’s bluejackets rescued 47 German survivors.

Air Attacks on German U-boats, WWII. U-801 was sunk on March 17, 1944, by a Fido homing torpedo by two Avenger and one Wildcat aircraft from USS Block Island, along with depth charges and gunfire from USS Corry (DD-463) and USS Bronstein (DE-189). Note, Lieutenant Junior Grade Paul Sorenson strafed, and Lieutenant Junior Grade Charles Woodell depth charged U-801. 80-G-222854

On 19 March, depth charges from an Avenger/Wildcat duo from Block Island sent U-1059 (Oblt. Günter Leupold) to the bottom. Escorts standing by rescued eight survivors.

U-1059 was one of Donitz’s rare torpedo transport boats, a Type VIIF, that went down after one very curious fight that ended up with a waterlogged naval aviator taking enemy POWs into custody at gunpoint.

As related by Uboat.net.

The sinking of U-1059. At 07.26 hours, the boat was attacked by an Avenger/Wildcat team from USS Block Island operating on ULTRA reports southwest of the Cape Verde Islands. The aircraft completely surprised U-1059, as she was not underway and men were seen swimming in the water. While the Wildcat (Lt (JG) W.H. Cole) made a strafing run, the Avenger dropped three depth charges that straddled the boat perfectly. U-1059 began to sink, but the AA gunners scored hits on the Avenger during its second attack run and it crashed into the sea, killing the pilot and one the crew. The mortally wounded pilot had nevertheless dropped two depth charges that sent the boat to the bottom. Ensign M.E. Fitzgerald survived the aircraft crash and found himself on a dinghy amidst German survivors. He helped a wounded survivor but kept the others at a distance with his pistol until USS Corry arrived and rescued him and eight German survivors, including the badly-wounded commander, Oblt Günther Leupold. (Sources: Franks/Zimmerman)

Shipping out on her third sweep, now VC-55 aboard in April 1944, Block Island’s T.G. damaged the veteran U-boat U-66 and, after a five-day chase, the destroyer escort USS Buckley found and rammed the pesky German submarine. Some 36 survivors captured by Buckley were later transferred to Block Island.

On the night of 29 May 1944, the Type IXC/40 submarine U-549 (Kptlt. Detlev Krankenhagen) managed to penetrate TG 21.11’s anti-submarine screen and get close enough to fire a trio of G7e(TIII) torpedoes at Block Island, hitting her with two.

As detailed by the NHHC:

Without warning, U-549’s first torpedo slammed into USS Block Island (CVE-21)’s bow at about frame 12; and, approximately four seconds later, a second struck her aft between frames 171 and 182, exploding in the oil tank, through the shaft alley and up through the 5-inch magazines without causing any further fires or explosions.

Meanwhile, the destroyer escort USS Robert I. Paine (DE-578) closed to join in picking up USS Block Island (CVE-21) survivors as the escort carrier settled lower and lower into the Atlantic. As she sank, the Avengers on USS Block Island (CVE-21)’s flight deck slid off into the sea like toys, their depth charges exploding deep under the surface. USS Block Island (CVE-21) took her final plunge at 2155.

USS Block Island (CVE-21) dead in the water and listing after 1st and 2nd torpedo hits. The ship was initially struck by two torpedoes from the German submarine U-549 on 2013, 29 May 1944. A third torpedo hit some ten minutes later and sealed her fate. FBI sank at 2155. NH 86679.

U-549 was soon after sunk by two of Block Island’s escorts, USS Ahrens (DE-575) and Eugene E. Elmore (DE-686), with all 57 of her crew, Krankenhagen included, diving with her to the bottom forever.

Amazingly, only six USS Block Island crew members died during or soon after the attack. Added to this were four Wildcat pilots aloft at the time of the attack who could not make it to the Canary Islands and were lost at sea.

Block Island’s name was stricken from the Navy List on 28 June 1944.

She was the only American carrier lost in the Atlantic in any war.

She earned two battle stars while her group was credited with sinking seven U-boats. Both of her skippers, Logan Ramsey and Frank Hughes, would survive the war and later retire as rear admirals.

Epilogue

A third Block Island, the second to carry the Navy on active duty, a late-model Commencement Bay-class escort carrier (CVE-106), was commissioned just six months after our ship’s loss, on 30 December 1944.

Of interest, Most of the original CVE 21 crew was reassigned to CVE 106, which was fairly unique in U.S. Navy history. This was done largely due to the will of Frank Hughes, CVE-21’s final skipper, and he would command the new Block Island in 1945.

This new carrier was also able to earn two battle stars for her WWII service in the final days of the Pacific War, then went on to serve again in the Atlantic during the Korean War and was decommissioned in 1954.

A veterans association remembers both CVE-21 and CVE-106.

Our little flattop is also remembered in maritime art.

“The BLOCK ISLAND in ’44” – CVE-21 USS BLOCK ISLAND with VC-55 aboard, May 1944 (Jim Griffiths)

The war diaries for both Block Islands are digitized in the National Archives.

The most tangible memory of CVE-21 is the Simmons Aviation Foundation’s Heritage Flight TBM-3E Avenger (N85650) that since 2011 carried the “Block Island” livery and tail flash of VC-55.

Of the rest of the Bogue class, Block Island was not the only member to feel the U-boat’s sting. British-operated sister HMS Nabob (D 77) was torpedoed by U-354 in October 1944 and so seriously damaged that she was judged not worth repair. Likewise, the same could be said for sistership HMS Thane (D 48) would be so crippled by U-1172 in 1945 that she was not returned to service.

As for the class’s post-war service, they were too small and slow to be utilized as much more than aircraft transports, and most of the British-operated vessels were returned to the U.S. Navy, retrograded back to merchantmen, and sold off as freighters.

Of the ten U.S.-operated Bogues, most were sold for scrap or for further mercantile use sans flattop and guns, with Card, converted to an aviation transport (AKV-40, later T-AKV-40) in the 1950s, remaining in service into Vietnam where she was embarrassingly holed by Viet Cong sappers in Saigon. The last of the class in American service, she was scrapped in 1971.

The final Bogue hull, the former Smiter-class escort carrier HMS Khedive (D62), continued operating as the tramp freighter SS Daphne as late as 1976 before she met her end in the hands of Spanish breakers.

Ships are more than steel
and wood
And heart of burning coal,
For those who sail upon
them know
That some ships have a
soul.
