The German ship was detected due to HF/DF.
Maybe so, but one of the crew of
Nigeria didn't think so. This is what Alfred Longbottom of Halifax in West Yorkshire (the original Halifax) remembered.
"The Navy were trying to locate a German Station providing weather and movement of shipping news to their own ships and submarines. I was on HMS Nigeria (a colony cruiser), and before getting under weigh we had a good idea of the general area in which the Weather Ship would be found but, immediately before the incident, it is most likely we simply 'came across' her. We were not at Action Stations, always triggered off by radar contact and often the result of locating floating debris, empty lifeboats and even whales! I was on deck as HMS Nigeria sailed into proximity to a large iceberg when I first saw an orange glow in the 'iceberg', followed by splashes of water in the sea near the stern of Nigeria. Almost with disbelief, I realised the iceberg had opened fire on us with enormously heavy guns, the splashes so clearly disturbing a perfectly calm sea - like a sheet of glass. At this point I could not see a ship. It was covered from stem to stern in white canvas. Together with our two destroyer escort we had located the German Weather Ship Lauenberg and it was June 1941. Scuttling charges sent the Lauenberg to the bottom. I well recall seeing two lifeboats packed with her crew being rowed away from their ship to the destroyer HMS Bedouin and internment."
Alfred recalled this in 2004 not long before his death.
An eyewitness account from
Tartar supports the contention that the
Lauenberg was first sighted by one of her look outs "behind that iceberg" rather than being tracked electronically .
Lauenberg didn't have 'enormously heavy guns', maybe he observed the 'fall of shot' from
Tartar which had opened fire on the German vessel immediately in order to panic the crew into abandoning her, a ruse that obviously worked. Tom Kelly, Chief Gunner's Mate on Tartar claimed he had been told to open fire immediately but not to hit the
Lauenberg, something he replied would be easy. That doesn't give one much confidence in RN gunnery
White canvass? There's none visible in any of the photographs. Memory is a fickle thing.
Other accounts say that
Lauenberg was sunk by gunfire rather than scuttling charges, but here I suspect Alfred maybe correct. It would have been far more reliable and economical and a demolition team may well have formed part of what was a substantial boarding party.
Much is made of the capture of the enigma machine but it was actually three pieces of paper, two headed 'Steckerverbindungen' (plug connections) and one which was a list of the 'Innere Finstellung' (inner settings) which comprised the most vital intelligence gathered. These three pieces of paper were what allowed the code breakers at Bletchley Park into the German naval codes for July 1941.
There is at least one photograph of the boarding party setting off for the
Lauenberg . There are plenty of 'tin hats' in evidence but though I can't see any cutlass or axes it wouldn't surprise me if both had been available on
Tartar and that both were carried.
