The Shell House Raid

An early morning walk around Copenhagen this morning reminded me of a longer visit I made here about 25 years ago, during which I rented a room in a nice large apartment on Frederiksberg Allé, which is in a rather posh part of the city called Frederiskberg. The landlord, who also lived on the premises, was a Mr Vagn Jul Pedersen, a nice old man who had lived in that part of the city all his life. One evening we sat talking over a beer or two and he told me of a terrible thing that he had seen during the latter stages of the Second World War when he was a young man, and I thought some of you might be interested to learn about it.

In March 1945, the British decided to carry out a low-level bombing attack on a target in Copenhagen, which was under German occupation at the time. The mission was given the codename Operation Carthage and its primary objective was the Shellhus (“Shell House”) originally owned by the oil company, but commandeered by the Nazis for wartime use as the Gestapo headquarters. The request to bomb the Shellhus came from the Danish Resistance, despite the fact that it was known that the top floor of the building was being used to house Danish prisoners as a kind of human shield.

I have based the following on a post I found elsewhere on the net. You can also read the official RAF account here.

By the end of 1944 the Danish resistance movement in Copenhagen was in danger of being wiped out by the Geheime Staatspolizei (Gestapo). Many of their leaders were arrested and a lot of material was filed in the Gestapo archives in the Shell house. Leading members of the resistance-movement requested an attack by air on the Shell House via the Special Operations Executive (SOE) in London.

Eventually on 21 March 1945, 20 de Havilland Mosquito fighter-bombers from 2nd TAF escorted by 28 Mustang Mk. III fighters from 11 Group took off from RAF Fersfield in Norfolk, England. 18 of the Mosquito bombers were F.B. Mk. VIs and 2 were Mosquito B. Mk. IVs from the Photographic Reconnaissance Unit (PRU). The Mosquito force attacked in 3 waves: 1st wave with 7 Mosquitoes (one PRU); the 2nd wave with 6 Mosquitoes; and finally the 3rd wave with 7 Mosquitoes (one PRU). The primary objective for the Mustangs was to engage, distract, suppress and, if possible, destroy anti-aircraft “Flak” batteries concentrated in central Copenhagen.

The first wave approached their target from the South West but, as they passed Enghave Station, which is near the famous Carlsberg brewery, Mosquito SZ 977, with Pilot W/Cdr. Peter A Kleboe and Navigator F/O K Hall, struck a 30 metre lamppost or pylon; the wingtip of the Mosquito then hit the roof of No 106 Sonder Boulevard. The two 500lb bombs carried by the aircraft ripped off and exploded, killing twelve civilians. Flying at roof-top level over a densely populated area it was inevitable that there would be casualties if a plane crashed or were shot down, but the Fates that day were in an especially cruel mood and far worse was to follow.

The stricken Mosquito “T for Tommy” crashed seconds later in a garage near the Jeanne d`Arc French Catholic school on Frederiksbergs Allé. The front part with the cockpit with the two crew members landed on Dr. Priemesvej; they were badly burned and later died of their injuries. Pilot W/C Peter A. Kleboe and Navigator F/O Reginald J.W. Hall were laid to rest in Bispebjerg Cemetery on 28 March 1945.

The rest of the first wave found and bombed the Gestapo Headquarters successfully. In all six bombs exploded in the Western wing and, of the nine prisoners in this part of the building, six were killed instantly and another died when jumping from the 5th floor to the ground.

But the tragedy that had begun to unfold at Frederiksberg Allé was about to get even darker. The 2nd wave of Mosquitoes became confused by the smoke and flames from the crashed Mosquito and thought it must be their target. Two of the Mosquitoes in the 2nd wave dropped their bombs on the French school and only one proceeded to bomb the Shell House. The 3rd wave approached Copenhagen from the West, and again became confused. All but one of the Mosquitoes dropped their bombs by mistake on the French Jeanne d`Arc Catholic School killing 86 children and 16 adults out of 482 children and adults, while 67 children and 35 adults were wounded.

This is the site of the modern Shell House, the original being completely destroyed during Operation Carthage. It’s quite easy to find, on the North side of Kampmannsgade, just to the East of Sankt Jørgens Sø, between Nyropsgade and Vester Farimagsgade. It’s actually quite close to the splendid modern Tycho Brahe Planetarium.

Inside the doorway at the far right of this building as seen in the above view is the following inscription, giving the names of the Danish resistance members who died that day

You can see here below a map showing the location. Enghave Station is to the South-West, the natural direction from which the incoming planes would have come. The Mosquito “T for Tommy” must have veered North, i.e. to its left, after its collision with the pylon in order to have crashed where it did.

Reading about this terrible episode, I was at first surprised that so many pilots misidentified the target, especially since the correct one is so close to Sankt Jørgens Sø, a prominent expanse of water that makes up one of a string of shallow lakes that extend along most of the Western side of Copenhagen’s city centre, which one would have thought was easily identifiable by its absence at the French School. The pilots had, after all, been shown detailed models of the location before the raid. But then I’m sitting at a desk with a map in front of me, not screaming along at 400mph, over rooftops bristling with anti-aircraft guns, into the teeth of withering Flak fire.

I walked the distance from the Jeanne D’arc School to the Shell House and I reckon it’s not much further than 1km, perhaps less as the Mosquito flies. That’s just seconds at the speed the planes would have been flying. That, together with the general confusion of smoke, gunfire and fear, could easily account for the navigational errors.

Owing to the presence of planes from the RAF photographic unit, there is remarkable film footage shot during the actual raid, some of which can be seen in the following film. It’s interesting how little Copenhagen’s skyline has changed; much of the city is immediately recognizable. There is also some very moving eye-witness testimony.

Even to a non-expert like me this was clearly an extremely dangerous mission. Mr Pedersen told me he saw Mosquitoes flying between the houses, along some of Copenhagen’s admittedly very wide roads, below the level of the rooftops; presumably the anti-aircraft guns were unable to aim downwards. A total of 4 Mosquitoes and 2 Mustangs were lost to flak with 9 crewmen KIA and 1 POW. Incidentally, one of the two Mustangs shot down that day crashed in Fælledparken, the park just behind the Niels Bohr Institute.

Mounted on the wall of the present Shell House is a bronze cast of a propeller from one of the downed Mosquitoes. A plaque is placed below the propeller with the names of the 9 crew members who were killed in the attack.

A total of 133 Danes died during and after the raid, including 86 children and 18 adults (including many nuns, and some bystanders who had tried to help) at the French School. At the Shell House, 8 Gestapo prisoners were killed and 18 managed to escape; 55 German soldiers and 47 Danish employees of the Gestapo died. In those days they hadn’t invented bland phrases like “collateral damage” to disguise the real horror of war, and it wasn’t possible to use unmanned drones as deployed by the US in their covert “war on terror”. Although Operation Carthage did achieve its objective, the loss of innocent life was so appalling it remains difficult to see it as a success.

I remember very well the tears in Mr Pedersen’s eyes when he told me about what had happened at the French School that day; it was only later that he found out what the actual objective of the raid was. At the end he said “You are lucky that you will never have to witness anything like that.” That goes for all of us who have had the good fortune to live in a time of peace. But let’s not forget the other parts of space-time where things are/were very different.

  1. Thank you for the detailed story. The 40 war graves at Bispebjerg cemetary can still be visited, and this website has information that is relevant to the 21/03/1945 event you describe:

  2. Well-researched, well-written account of a story that needs to be told. I recently visited the memorial on Frederiksberg Allé; it’s so sad what happened there.

  3. I just watched the clip without sound, so I don\’t know where it is sourced from, but I agree that the mosquitoes over Copenhagen were flying very low and very fast, and very dangerous.

    The thing that was odd was the other aircraft interspaced through the clip, with german He111s, Lancasters, the tail of a Marauder (I think) and even a Stuka. It must have been a busy day above Copenhagen.

    • telescoper Says:

      I think they were there to illustrate the development of bombers during WW2 and the importance of the airforces on all sides. Traditional bombers would have been nowhere near accurate enough to hit the Shell House.

      • Thank you for your dedication to this part of history. i am writing a biography of my parents and this has been useful.

  4. Monica Philpott Says:

    Thank you for this most moving account of the raid on Shell House Copenhagen . My uncle Flying Officer Fergus Murray piloted one of the Mosquitos. He was hit and came down over the coast. His aircraft was named the ‘Monica K’ after my brother (Kevin) and me.
    All so sad.

  5. My mother was at the school when this took place. Her and a few classmates survived only because they were in a stairwell at the time of the bombing. I am here in Denmark now and have brought my mothers grandchildren with me. Our intent is to find the location of the schoolhouse. I will use this additional information as I explain to them what happened.

    • MONICA Philpott Says:

      If you have not found the site of St Jeanne d’Arc school it is 74 Fredericksburg Alle in the centre of Copenhagen. A wonderful memorial stands of a statue of young children. A moving tribute of that day MONICA Philpott

  6. Chris Chisholm Hamilton Says:

    My father was a pilot of one of the Mustangs and was shot down.
    He was taken POW for the last couple of months of the war.
    His name was Robert Chisholm Hamilton, an Australian flying with the RAF.
    I remember as a child he said a Mosquito pilot crashed in front of him, Dave Drew was his name.
    I was contacted by a museum in Copenhagen only weeks after my father died (1984) about parts they have of his plane.
    Would love to know more about that.

    • Dear Chris, I don’t know much about the story, but the page I mentioned in my comment above from 2012 does list David Arthur Drew that you mention, and there’s a sub-page about him:
      The Commonwealth War Graves Commission’s page does not have much information:,-david-arthur/

    • Christopher Turner Says:

      Chris: I am an historian living in Copenhagen and can check out what the museum has. My understanding is that your father crash-landed his Mustang after it was damaged by flak. Do you recall the museum’s name?

      • Chris Hamilton Says:

        Hi Christopher,
        I don’t know the name of the museum, but a link here:
        shows a pic of (possibly) the recovered part from the wreckage.
        I thank you for your reply.
        I know he ended up in Stalag Luft One.
        A message was given by a Dane (a wink) present when he was captured.
        His mother was notified that he had survived the crash, soon after initial reports of having not.

      • Chris Hamilton Says:

        Another link that connects the wreckage.

        Can’t understand the language, but very surprised to see this.

    • Christopher and Says:

      Chris, That piece is definitely from a Mustang Mk III. It was part of the canopy, which in this variant had a Malcolm Hood that was used on the Spitfire. The Mk III as configured for the RAF had two fixed plexiglass canopy sections on either side of the Mustang’s razorback, just aft of the sliding section of the canopy. I’ll poke around Denmark a bit and see what I can find. I have some contacts in academia and the military who might be able to help. If I discover anything interesting, I’ll write it up and send it your way. Many thanks for writing back and sending a link to that video.

      • Christopher Turner Says:

        My last message did a strange autocorrection to my surname.

      • Chris Hamilton Says:

        Thanks again, it’s amazing what you can find all these years later.
        Look forward to hearing what you find.

        A link, in his own words.

        Apologies, in my initial post I said Dave Drew was a Mosquito pilot, of course he was a Mustang pilot.

      • Christopher Turner Says:

        Thanks for the link to those scanned documents. Fascinating. I’ll post an update once I’ve found anything interesting.

    • How?

      I mean where can I see it?

    • I’ve updated this with an excerpt of a documentary, which contains some amazing footage of the raid as well as very moving eyewitness testimony.

      I also learned that some of the anti-aircraft fire on the incoming planes was actually from a German cruiser situated in the harbour.

    I’m a volunteer at the Bentwaters Cold war Museum and have collated lots of info on this event and would like to make contact with Chris Hamilton. Please drop me a line at my e mail address and I can help you with info and you can share your father’s with us for the museum which covers his time there in the war.

    Reblogged this on In the Dark and commented:

    Almost forgot that the grim events described in this old post took place in Copenhagen 75 years ago today…

  11. Thanks.

    Very powerful testimony.

    The chaos of war leaves so many victims.

  12. ashley winter Says:

    David Drew was my great uncle, my grannie’s little brother – extremely proud of him.

    • Christopher Turner Says:

      Your great uncle’s final resting place is in the Commonwealth Graves section of Bispebjerg Cemetery in Copenhagen. (It also holds the graves of the two Mosquito pilots who crashed near the French School.) It is very well tended; I have visited several times. Once the current global health crisis abates, if you ever visit Copenhagen, perhaps you can stop by and leave flowers.

  13. Simon Gladas Says:

    Hello Ashley, have you made contact with Derek Carter? He has researched this subject extensively and lives in Copenhagen and I was privileged to spend the day with him and relatives of Fl. Lt David Drew being given a guided tour on the 70th anniversary of the raid in 2015. I have created a display at the Bentwaters Cold War Museum where your great uncle flew from to honour his loss and the efforts of all those who served.

    Copenhagen october 2021
    In the end of world war two, the danish restancemovement, desperate requested the royal airforce to bomb the Gestapo headquarters. Tragic som of the planes and bombs hit the “French school” in Copenhagen, and many civilians (kids) died. This is a well documented episode of unintentional damage during the war. The young pilots did there best. Now a famous and skilfull director :Ole Bornedal, (but with no moral standarts at all – except the hunt for fame and money) is releasing a film of the tragedie. “To show the fragility of life”. On behalf of the decent citicens of Denmark – My appologies to the families of the brave Brittish airmen who fought the naziocupied Denmark.
    Yours sincerely, Mikal Rode
    (Please pass this on.)

    • Chris Hamilton Says:

      The Danish feature film “Shadows In My Eyes” is the story behind the inconceivable tragedy that hit Denmark 21 March, 1945 – the catastrophic bombing of the French school in Copenhagen.
      Released on 28th October in Denmark, then internationally via Netflix.

  15. Mikal Rode Says:

    This tragedy was not a war crime, but a fight against war crimes – let’s hope the instructor does not blacken the brave young pilots who risked their lives to help others.

  16. Ken Powell Says:

    It was a war crime and those reponsible should be held guilty. As unjustified as the Russian bombing of Ukraine.

    • Mikal Rode Says:

      Dear Ken Powell
      Im’ sure that your intentions are the best. But please let me explain something for you: a crime is per definition don intentionally, otherwise it is the case of an accident. Consequently, the tragic bombing of the french school was an accident followed up by mistakes. No one, not even the nazi perpetrators thougt, that the brave brittish airmen did it on purpose – what would the point be, when they were having a much more importent goal close by??
      Yours cincerely, Mikal

    • D Close Says:

      Ken Powell. It is not a war crime and your comment is disgraceful. An accidental bombing when the target was a military facility is not a war crime.
      Your pro Putin stance is a stain on the tragic loss of civilian life

  17. Steve Harris Says:

    The film “Skyggen i mit øje” of this incident is now on Netflix under the title Bombardement as is excellently portrayed.

    • Mikal Rode Says:

      Dear Steve. I disagree with you. This inacurrate film was made for money. I dont’ know who pays your sallery, but this is – in my oppinion, morally wrong.
      Best of luck, Mikal

  18. Carolina Says:

    I don’t understand why there’s not any apology document about this huge mistake. In those cases, the crown would at least try to appear regreted, specially involving the church. I didn’t find anywhere. If anyone has this lik, please, send to me. It’s like they just ignore it.

  19. María Angeles Perez Says:

    Agree Carolina. May not be a war crime, but of course deserves a formal and sincere apology. A tragic and horrible mistake.

    • D Close Says:

      Representatives from the British Embassy lay a wreath every year. The RAF released a tribute video in 2019.

      There is no need for an apology and importantly, Danes have never asked for one

  20. Mikal Rode Says:

    Although objectively it was not a war crime, but a tragic accident, one should always in principle give an apology in such cases. This should be one of the differences between democracies – and then the Nazi regime, which never apologized for any of the millions of murders they committed against innocent people.

  21. telescoper Says:

    I wrote this post almost a decade ago, but in the last week or two it’s received more traffic than in the previous ten years put together and I have no idea why!

  22. Mikal Rode Says:

    Maybe it is because a Danish director has produced a film about the attempt to bomb the Gestapo’s headquarters – which also succeeded, but unfortunately also resulted in a wrong bombing of a school. The film of the tragedy, which received strong protests from living family members to the British pilots who risked their lives and limbs to help the Danish resistance movement, resulted in the film being the only one in Danish film history to be forced to change and cut in the film – after the premiere date ! As it was both historically incorrect and immoral. I personally do not intend to take part in this debate any further, as some of the posts have seemed unethical and unreliable. Our thoughts should go to the children and families who were affected AND the brave British pilots. Honored be their memory.
