The Oslo Mosquito raid (25 September 1942) was a British air raid on Oslo, Norway that was sanctioned by the Exiled Norwegian government in London [1] during the Second World War. The target of the raid was the Victoria Terrasse building, the headquarters of the Gestapo. It was intended to be a "morale booster" for the Norwegian people and was scheduled to coincide with a rally of Norwegian collaborators, led by Vidkun Quisling. The raid is also known for it being the moment when the Royal Air Force revealed the existence of the Mosquito aircraft to the British public, when the BBC Home Service reported on the raid the following day.

Background

Barely twenty days after the Germans invaded Norway on 9 April 1940, an advance force of the Gestapo arrived at Fornebu in fourteen Junkers aircraft, after a short stay at the blindern Students Hostel and at a suburban hotel in Oslo, the gestapo moved into the foreign minster building, Victoria Terrasse, in the beginning of May 1940. [2]

In Autumn of 1942 resistance groups across occupied Europe, in consultation with Britain, agreed that the various gestapo headquarters should be bombed, the first target selected was Victoria Terrasse in Oslo. shortly before this, the RAF, which was to carry out the raid, had taken delivery of a new and believed unrivalled aircraft, the de Havilland Mosquito and decided to use it for the raid due to its excellent low altitude performance[2]

Victoria Terrasse was being used by the Gestapo and was in direct communications with Reich Security Main Office and under the leadership of SS Hauptsturmführer Siegfried Wolfgang Fehmer.[2]

On 25 September the Norwegian Nazis collaborators headed by Vidkun Quisling had arranged a major party meeting and as German fighters were not normally stationed at Fornebu, four Fw190 from 3 staffel JG/5 were sent to provide air cover [2]

Preparation

The operation was carried out by four de Havilland Mosquito aircraft of No. 105 Squadron RAF, led by Squadron Leader George Parry, flying with navigator Flying Officer "Robbie" Robson. The other three crews consisted of:

  • Flight Lieutenant Pete Rowland and Flying Officer Richard Reilly
  • Flying Officer Alec Bristow and Pilot Officer Bernard Marshall
  • Flight Sergeant Gordon Carter and Sergeant William Young.[3]

In order to shorten the mission distance, the four aircraft were flown to RAF Leuchars in Fife, Scotland, where they were refuelled and loaded with 8 delayed action 1,000-pound (450 kg) bombs, each aircraft having 2 [2]

The operation

The operation began in the early afternoon of 25 September when 4 mosquitos of 105 Squadron took off from Leuchars, they had to travel a distance of 1,100 miles (1,800 km) with a flying time of 4.75 hours, making it the longest mission flown with Mosquitos to date. The bombers crossed the North Sea at heights of less than 100 ft (30 m) to avoid interception by enemy aircraft and navigated by dead reckoning.[3] Each aircraft was armed with two 1000 lb bombs with an 8 second delayed action fuse since in such a low level attack the bombs had the potential to damage the aircraft that dropped them.[2]

As the Mosquitos were making their way to Oslo along Skagerak they were spotted and the 4 fw190 were informed that four twin engine bombers have been spotted, they immediately scrambled but only Klein's and Unteroffizer Fenten's aircraft were equipped with integral starters, ten minutes after taking off they spotted the Mosquitos assuming they were Douglas Bostons[2]

Unaware of the dangers the Mosquitos made it and clearly identified the target due to the good weather and went in dropped all their bombs with the pilots noting they all landed near the target with Parry believing he scored a direct hit but the Fw190s managed to catch up with them finally as this was happening. [2]

Squadron Leader Parry and Flying Officer Robson's aircraft (DK296G) was first and successfully attack the target from 100ft, before being engaged by two Fw 190 over the target, they managed to evade and observed direct hits on the main building before flying back and landing at RAF Sumburgh.[4]

Flight Lieutenant Rowland and Flying Officer Reilly's aircraft (DK313U) was second and also successfully attacked the target at 100ft, this time the aircraft was attacked by one fw190 after flying away from the target, they were able to escape and land safely back at RAF Sumburgh despite suffering damage from cannon-fire.[4]

Flying Officer Bristow and Pilot Officer Marshall's aircraft (DK328V) was third and successfully attacked the target at 100ft. It was then engaged by two enemy Fw 190 over the target but they were then able to successfully evade them and then landed at RAF Sumburgh on return. [4]

Flight Sergeant Carter and Sergeant Young's aircraft (DK325S) was last and was attacked by Erich Klein's Fw 190 over the target causing smoke to pour from the starboard engine, the other 3 aircraft saw this and Carter radioed that they will try to land in sweden. the aircraft ended up landing in a lake on the outskirts of the city, the bodies of Carter and Young was recovered by two Norwegians, Rikard Nilsen and Fredrik Høgli with the help of dye from bags that the airmen were wearing. DK325S was later recovered by the Nazis however the plane had already been looted by Norwegians

Flight Sergeant Carter and Sergeant Young both died in the crash, Carter at the age of 28 and the Navigator Young at the age of 20, they were buried at Vestre gravlund.

A few days afterwards Britain became aware of the damage, of the 4 bombs to hit, 1 failed to detonate and the remaining 3 crashed through the building before detonating leading to minimal damage causing the raid to be deemed a failure.

Impact

Although the raid had failed to achieve its objective, it was considered dramatic enough to be used to reveal the existence of the Mosquito to the British public, and the following day (26 September) listeners to the BBC Home Service learned that a new aircraft – the Mosquito – had been revealed for the first time by the RAF, and that four had made a low level attack on Oslo. The Mosquito bomber was featured in The Times on 28 September, and the next day the newspaper published two captioned photographs illustrating the Oslo bomb strikes and damage.[5][6]

Victoria Terrasse also remained in operation after the attack leading to another bombing raid on 31 December 1944 which also failed to destroy the building.
