Over 70 years after a British steampship from Bombay carrying
tons of Indian 1 rupee silver coins to help fund Britain in World War II was
torpedoed by a German submarine, its wreck has been discovered in a record
deep-dive operation.
The SS City of Cairo (Captain William Rogerson) was a
mixed cargo and passenger ship belonging to Ellerman Lines and was on a voyage
from Bombay to England, via Cape Town and Recife, Brazil, unescorted, in late
1942, in the middle of World War II.
The ship carried 296 people of which 136 were
passengers and a mixed cargo including some 100 tons of silver coins belonging
to the UK Treasury. It was spotted by U-68 on the 6th of November 1942 and
torpedoed near St Helena in the south Atlantic at 2030 hrs.
The story of the torpedo is known and has been the
subject of at least one book, but the shipwreck was never found until Deep
Ocean Search (DOS), a company specialising in such operations, took on the
challenge under a contract with the UK government.
The company gets to keep an unspecified amount of the
coins under the contract with the Ministry of Transport. DOS said it recovered
several tens of tons of silver coins from a depth of 5150m – a world depth
record. The haul is expected to be worth millions of pounds.
The story goes that the surviving crew and passengers
were in lifeboats when the submarine approached to question captain Rogerson.
The U-Boat captain, Karl-Freidrich Merten, told him how far he was from Brazil
and left saying, “goodnight, sorry for s
DOS said: “This was to be a difficult search as the
water depth would exceed 5000m, the weather, swell and currents were known to
be challenging and the presumed site was some 1000 miles from the nearest land
in the foothills of the mid-Atlantic ridge”.
It added: “Our research came up with the usual
contradictions between the positions given by the submarine and that from the
ships officers. A large search box was put together to try to reconcile these
diverse statements. The seafloor was difficult with ridges and canyons
throughout the area and the water depth varied between 5100 and 5500m”.
Divers founds that the ship was broken in two and
buried deep in the seafloor silt. Parts of the ship had meters of mud heaped
upon it.
“The combination of pressure, temperature, repeated
dives at this depth and other issues resulted in multiple breakdowns of systems
such as we had not experienced before when working in 3000 - 4000m
depths…However our team overcame them”.
The DOS team left a plaque commemorating the finding
and visiting the ship before they left the site finally.
