Altmark Incident

16 Feb 1940


ww2dbaseThe German tanker and supply vessel Altmark, formerly under service with the pocket battleship (later re-classified as heavy cruiser) Admiral Graf Spee, had been in hiding in the vast Atlantic Ocean after Graf Spee had been defeated by an Allied task force at Montevideo. Though she successfully evaded detection for the nine weeks after Graf Spee's destruction, she was running low in fuel and must make port call to re-supply. On 16 Feb 1940, she was found by Royal Air Force pilots off Norway. Upon hearing the news, Lord of the Admiralty Winston Churchill jumped on the opportunity to bring good news to the people of Britain. Thus far, Britain had been fighting what William Manchester called a "Bore War". The British people had been keeping strict blackouts and enduring other war-time restrictions, but because the war had not been brought to them, the British people were suffering in morale. Knowing Altmark carried the crew of the merchant vessels Graf Spee had sunk, Churchill wanted to use this for boosting British morale as well as his own political popularity. He left word that any news regarding Altmark was to be sent to his office immediately, and that was what Captain Philip Vian did.

ww2dbaseVian was the captain of the British destroyer Cossack. Cossack caught up with Altmark near Jøssingfjord, and Altmark prompted retreated into the fjord under protection of two Norwegian gunboats. Though officially neutral, Norway adopted a policy to appease the Germans to avert the spread of war into Scandinavia. The two gunboats, claiming that Altmark was unarmed and did not carry any prisoners, was a neutral civilian ship, therefore would not allow Cossack's crew to board her. From London, orders arrived for Vian to offer his Norwegian counterpart to jointly escort Altmark to Bergen, but the Norwegians refused. Churchill's next order was for Cossack to forcefully board Altmark, though attempt to avoid combat with the neutral Norwegian ships even if the Norwegians fired on them first. Cossack steamed into the fjord, happy to see that although the Norwegian ships refused to accompany the British destroyer on a joint boarding, they did not interfere, either. Very quickly, Altmark revealed that she was in no way "unarmed" as the Norwegians claimed. Firing two "pom-pom" guns and four machine guns at Cossack, Altmark made a turn for Cossack and attempted to ram her. An unskillful maneuver, however, caused Altmark to run aground, effectively ending the incident. The boarding party opened the hatches of the empty oil tanks and yelled "are there any English down there?" A collective response from 299 captives was heard. "Well, the Navy's here!", exclaimed the boarding party. The prisoners were transferred onto Cossack, and the German vessel was allowed to resume her journey back to Germany.

ww2dbaseChurchill did all he could to publicize this "victory" to boost morale. He had no jurisdiction over the Royal Air Force, and the French held the key to ground combat, so when his Royal Navy met success, he squeezed every ounce out of it. On 23 Feb, he gathered the heroes of the Battle of the River Plate at Guildhall, comparing them to Horatio Nelson in his "the Navy's here" speech that made its way around all major British newspapers. Although the prisoners were not abused aboard Altmark, their conditions were exaggerated to add fire to the rumors of Nazi atrocities in Poland. Even King George VI sent Churchill a personal note to congratulate him on the successful rescue mission.

ww2dbaseIn Germany, this relatively small incident changed the direction of how Adolf Hitler wanted to conduct his war. Upon hearing the news that the 299 British prisoners were lost at the cost of four German lives, he was reported to be mad that the crew of Altmark did not fight harder against the British boarding party. Until this point, he had wanted to keep Norway a neutral nation so that Germany's need for Swedish iron ore, which must be transported through Norway, could remain uninterrupted. If Norway entered the war, regardless of on whose side, Norway ran the risk of being occupied by Allied forces, and the supply route would come under risk. While prior to this incident he was already presented with the Kriegsmarine plan to invade and occupy Norway, he had personally ordered a halt on such a plan; that was so until the Altmark incident, said General Nikolaus von Falkenhorst during the Nuremberg trials. After the incident, Hitler was convinced that he could no longer trust Norway's neutral position, and action might need to be taken to safeguard the 11 million tons of iron ore that Germany needed from Sweden annually.

Dear Sir My name Jonathan Joseph Strong of Berwyn Pennsylvania and i'm writing a science-fiction novel using warships that was planned and some that weren't except by planners.I'm using WW-II warships that are fictional like the Midway-class that weren't commissioned except after the war.And extra Essexes and Independences.I'm also upgunning the British Pacific Fleet with ships that were not built like the Malta-class,the Eagle-class of which two were commissioned after the war in the nineteen-fifties.Plus oodles of fictional escorts from battleships to submarines and fictional aircraft.Also i'm using fictional Imperial Japanese Navy warships that were built in secret.And believe you me i'm talking major BANG-BANG's here.I'm not just using WW-II ships and aircraft and troops i'm using i'm using triemes and ships of the line ironclads etc.But where the science-fiction comes in you're wondering?I've got the idea a few-years ago when i read a story about the Third-Fleet running smack into two different typhoons sinking three destroyers in the first-one and a lot of damage in the second-one in June 1945.They're called Cobra and Viper.I call mine Rattlesnake that hit TF-87 which is fictional.And where did they ended up your're wondering? E.T.phone-home would you believe?What i need from you guys is information about the non-real ships that weren't built.And about the real ones as well.If you can't get me by E-mail my regular-address is 237 Leopard Rd Berwyn Pennsylvania 19312 I remain Jonathan J.Strong

Dear Mister Chen,

I have read your article about the 'Altmark Incident'. This is the version I've met 25 years ago, but in 2008 I read a book that dealt with this incident on about 70 pages and it defies with many statements described here.
The book is in German (maybe available in English too): R. K. Lochner: Als das Eis brach (When the Ice broke), München 1983

There you can read among others:
1. there were only 2 MG's on board of the Altmark
2. the Germans had received the straight command from Captain Dau not to use any weapons if they are attacked
3. in fact no weapons were used by the Germans (Norwegian eyewitnesses testified this on court after the battle)
3. Altmark hit the shore deliberately - because Captain Dau feared the British would take her with them - and not by an unskillfull manouver
4. the prisoners weren't kept in empty oil tanks
5. they received about the same provisions all the time as the German sailors
6. the hatches were opened by the Captain himself and by the prisoner-officer (both Germans already prisoner of the British), and weren't opened by the boarding party
7. at this point many freed prisoners thanked Captain Dau for the good treatment they received, some of them even shook his hand
8. after the incident, the British refused to take part on the hearing led by a Norwegian court in Egersund
9. German and Norwegian survivors and eyewitnesses spoke out here, gave their statements to protocoll

I think this book is worth reading.

Best wishes.

Hi I am researching our local War Memorial In Worthing and one of the names is J J F Smith, the only reference I can find about him was that he was badly wounded and rescued from the Altmark. Do you have any details of those British servicemen rescued. Any help would be greatly appreciated. Thank you Pam

Hi .. I am doing some research for an old friend who is tracing his family tree. I am looking to find a list of names of British servicemen that were rescued from the Altmark. Do you happen to know if such a list exists?
Thanks so much. Bren.

Hello Bren , not sure how your research is going but my grandfather Harry Langley was a prisoner on the Altmark , his name I found listed on this page https://archive.org/stream/atmarkaffair006961mbp/atmarkaffair006961mbp_djvu.txt which appears to show all of the prisoners. And incidentally there is a youtube video showing the return home of the prisoners . https://www.youtube.com/watch?v=iUCWv3PH9rw&t=18s
At the point of 32seconds into the video my grandfather is the gentleman at the front waving his hat. He passed away in 1978 and I was too young ever to question him about his experiences , so I am still mostly in the dark about what went on.Hope this is of some help
