Sinking of the Ship
Francis Reginald Broad, the British master of the British tanker Empire Gem, was a confident, self-assured man as his 8,139 ton vessel left Port Arthur, Texas on January 18, 1942. He was proud of the cargo she was carrying - 10,600 tons of gasoline for the Petroleum Pool Board. He was equally proud of his all British crew, which he felt was thoroughly loyal and able to deal with any of the hardships of war.
The Gem's full load was being transported from Port Arthur to the United Kingdom by way of Halifax, where she was to join a convoy. Although she hoped not to use them, the ship was equipped with guns for dealing with any marauder. On her stern was a four- inch gun, and elsewhere were six machine guns and a 12 pound anti-aircraft weapon. It was as well to have them since the German submarines had commenced operations off the eastern US coast.
The skipper followed the British Naval Control instructions closely as he zigzagged his course up the east coast. Broad took great care to zigzag and to travel at night with dimmed masthead and side lights.
As the Gem neared Cape Hatteras on the morning of Jan. 23rd, the Captain became more scrupulous in his cautious approach. Less than a week earlier, submarines had struck three times in the vicinity between Hatteras and Wimble Shoals.
Late that afternoon, the Gem sighted another merchant ship, the Venore. As night fell, the Gem closed her distance to the Venore until she was within three miles. Both ships turned on their running lights. Standing on the bridge, the Captain was pleased to note the clear weather, with excellent visibility. The moon shone so brightly that the Gem could have proceeded without her lights. The Venore could be seen in the distance with her lights also shining brightly.
The Gem had reached a position 15 miles southeast of the Diamond Shoals buoy when she was rocked by a terrific explosion in what the Captain judged to be one of the after tanks on the starboard side. The damaged section enveloped in roaring flames which were spreading rapidly. Korvettenkapitan Zapp and his U-66 had indeed, once again shown their skill and luck with an expert attack on a large tanker.
The chief radio operator reached the bridge and tried to send a message
after the torpedo hit. At the same time he heard the Venore sending an
SOS. Throughout the calamity, the ship's engines were running, taking the
Gem on a westerly course. Three hours after the attack, the engines finally
stopped. Three officers (the only survivors of 57 men) anchored the still
burning vessel in 28 fathoms of water. As the dawn of the next day crept
over the horizon, the torn and gutted after half broke away and sank.
Approximately three hours later, a Coast Guard lifeboat attempted to
rescue the three officers. Rescue was hampered by the flaming gasoline
and the high seas. The trio jumped into the sea to swim to the rescue boat.
However, Radio Operator Ernest McGraw was swept into the burning fuel by
the seas and perished.
It was not until later that the two survivors knew the fate of the Venore. They had assumed that from the SOS received that the Venore had been attacked first, when as a matter of fact the glow of the flaming Gem had illuminated the Venore for Zapp's torpedo attack. The Venore had spotted the submarine heading for her, and she sped away from the blazing tanker, but even with evasive maneuvers she had been unable to outrun the sub and the Venore joined the Gem adding two more vessels to Zapp's record (now totaling five for this patrol).
Diving the Gem
Today,
experienced divers will find the Gem (also known locally as the "smell
wreck") in two distinct sections that are in line with each other with
about 75 to 100 feet separating the two. Strangely, the stern section is rotated
180 degrees with the fantail facing the torn off bow section and the engine and
torn section facing away. The bow section is the largest portion
comprising about 2/3 of the wreck and lays completely upside-down.
Although
large and impressive to see, the bow offers nothing other than a large looming
hull bottom to inspect with some sparse scattered debris to either side.
The entire bow section is intact from the stem to where the hull was torn in
half just prior to the engine room. However,
it is completely upside down with both gunnels buried deep in the sand –
simply a huge encrusted hull bottom with nothing in the way of artifacts or
anything else of interest.
The
stern of the wreck is where to find the most exciting diving, as it is fairly
upright with many of the internal portions exposed through the collapsing decks.
The entire stern has a pronounced list to the starboard with a larger amount of
debris lying in the sand to the starboard side. The prop and rudder are
clearly visible as is the steering quadrant and many large deck fittings on the
fantail. Forward of the taffrail to the engine area is fairly intact with
some holes allowing access to the lower decks and machinery. On the port
side just aft of the engine are some areas that can be entered and explored, but
I have yet to find much of interest in these small compartments.
At
the engine room, the structure has fallen away exposing the large engines and
other equipment. The twin diesel engines are arranged not side by side,
but fore and aft on the centerline of the engine room. They are at least 8 to ten feet wide and the tops of the
engines have massive rocker arms that are a yard long.
About 25 feet forward of the engine the wreck ends abruptly where the two
sections where torn apart. This
exposes the remains of the torn away and collapsing decks descending to the sand
where a debris pile of torn metal is found.
The
wheelhouse is found upside-down, just off the side of the wreck several yards
away. In the standard visibility
you will not be able to see from the main wreck to the wheelhouse. At the sand there is a scattered debris field and divers have
reported seeing portholes and other artifacts there. It will take many dives to see the whole stern section
clearly as visibility varies greatly with the current, which can be very strong
in this area and usually is. However, we have dived the Gem in conditions
with no current and over 100 feet of visibility and it is impressive in these
circumstances. One must watch their gauges as we have seen over 150' in
the wash areas and there are some deep holes out in the debris field to the
starboard side of the wreck as well. Time
seems to go quickly when diving the Gem maybe it's all the great artifacts and
big fish. 
Come
see for yourself why the Gem truly is a "gem".
