Seventy six years ago, today, 28 March 1943 at 0733, the
Northbound Convoy, SR3, escorted by HMS Bridgewater and HMS Burdock sighted the
Southbound convoy at about 95 nm South of Gran Canaria and the escorts were
exchanged. This left RS3 steering 222° at a speed of 8½ knots. Burdock was on the port and Bridgewater on
the starboard at 3000 yards and 10°
before beam.
One of the crew members of the Lady Denison Pender, Ken
Smith, a cable jointer, recalled that “early on the Sunday morning the sea was
calm with blue skies and a warm sun. The Lady Denison Pender was a cold ship, built specifically
for service in tropical climes, so there was no heating in the accommodation
and most of the officers and crew had no warm clothing to protect them against
the cold. It was a blessing to us all to be steaming south and into warmer
weather. Around eight o’clock in the morning a northbound convoy appeared. As
the two convoys passed the escorting vessels changed over–our escorts took over
the northbound ships, and their escorts came to us. Normally on a Sunday morning those members of
the crew that had no duties to perform would be lounging about the deck,
enjoying the fine weather. It was also a good day to do the weekly dhobiing. At
around ten o’clock I was below decks on my way to the mess for morning coffee
when there was an explosion; being close to a port I looked out. On our port
side a cargo ship was folding in what can only be described as a giant letter “V”.
She had been struck amidships by a torpedo. The two escorts circled around,
dropping depth charges. The convoy took on a zigzag course and one of the
tugboats held back to pick up survivors or to render assistance.”
The explosion, at about 1150Z, was the SS Lagosian which had
been torpedoed by U-167. A survivor from
the Lagosian, Jim Kelly, recalled: "we passed the Canary Islands at about
nine am and continued our journey, passing what appeared to be the Portuguese
fishing fleet then, at eight minutes to twelve, we were attacked by a wolf pack
of submarines and we were hit by a torpedo and started to sink very rapidly. I
happened to be out on deck reading a book, before going on watch at midday. It
was about horse racing and the name of it was "The Finish". Just as I
had finished the story and closed the book, the torpedo struck and all the lads
on deck made a dash in the direction of the nearest lifeboat, which was
unfortunately full of holes, caused by the explosion. I then turned to lower a
raft. The axe, which hung on the rigging and was intended to release the raft,
had been blown away by the explosion. However, I managed to find an old shovel
lying on deck and this I used to release the raft and get it into the sea,
which was fairly rough at the time.
Bridgewater sent Empire Dennis to look for survivors. Meantime, Bridgewater and Burdock engaged
various contacts unsuccessfully during which a Hedge Hog attack attempted but
aborted when contact was lost. The hunt
was broken off at 1250 with ASDIC (the name given to underwater active sound
detection) conditions reported as "extremely poor with a great deal of
quenching (aeration of the water causing disruption to sonar signal reception).
Ken Smith continues his story. “For the next few hours everything seemed to
have slowed down, all was calm and serene, and at twelve-thirty the midday meal
was served. During the meal there was a terrific explosion, which had so much
force that the Lady Denison Pender listed
to starboard with all the crockery sliding off the table and smashing on to the
deck. My first impression was that the ship was being fired upon by small arms
with the bullets striking the deck and superstructure. Grabbing my life jacket
and rushing on to the upper deck, I was just in time to see the stern quarter
of a ship disappearing below the waves. The ship had been blown out of the
water. What I had taken to be machine gun fire was the debris from the
stricken ship raining down on to our decks.”
The tremendous explosion at about 1444Z had been caused by U-159
which had fired a spread of 4 torpedoes and heard "several detonations." Bridgewater also reported a "tremendous
explosion bearing 222° full
ahead” and that Silverbeech appeared to be missing.
HMS Bridgewater noted that as no torpedo tracks had been observed
and second explosion took place 16 miles ahead in 120 fathoms of water there
was a possibility that mines had been laid in this well used channel. She ordered the convoy to steer West for
deeper water. Meantime, U-172 had been chasing the same convoy and had
been badly shaken when a ship (presumably Silverbeech) blew up only about 2000
metres away. Bridgewater further reported a heavy underwater explosion, thought
to be the remaining cargo of ammunition at 1410Z hours.
U-159 later surfaced and passed a large field of debris including
several pieces of twisted metal on their deck.
The Captain of the Empire Ace said he "heard a dull explosion as
the torpedo struck the Silverbeech, followed a second later by a terrific
explosion as the forward part of the ship blew up. Wreckage was thrown into the
air to a height of 1000 ft, some of the ships plates were blown as far as the
Empire Ace. The torpedo appears to have
struck the No 2 hold in which was stowed about 93 tons of TNT. The poop,
apparently, remained afloat for about 7 seconds before it slipped under,
leaving nothing but a mass of wreckage where a few seconds before Silverbeech
had been. Silverbeech had blown up and sank at position 25.30N 15.55W.
The Master, 50 crew and 5 Gunners and passengers were
lost. Amazingly, 2 of the crew and 6
Gunners were rescued by the British Tug Empire Ace and landed at Bathurst (now
Banjul) Gambia. The Gunners probably
survived because their accommodation was in the poop which had remained afloat
after the explosion.

Helmut Witte
The Captain of U-159
was Helmut Witte (6 April 1915 – 3 October 2005). As commander of the Type IXC
boat,
U-159, he sank twenty-three ships on four patrols, for a
total of 119,554 tons of Allied shipping, to become the 20th highest scoring U-Boat
ace of World War II. He was awarded the Knight's
Cross of the Iron Cross given recognising extreme battlefield
bravery or successful military leadership.
The Master and crew of the MV Silverbeech are commemorated
at the Tower Hill Memorial. The memorial
is adjacent to Trinity House and lies just to the North of the Tower of
London. Twenty four thousand names are
inscribed in panels around the memorial and it is very moving to behold. Second Engineer Officer Arthur Norman Gandy
can be found on Panel 97 together with the Master and 17 other shipmates.
