On 20 August 1946, German high explosive bombs were being loaded onto barges for disposal at sea when a 50 kilograms (110 lb) bomb was dropped and exploded, killing six and injuring 12. Two train loads of bombs were ready for loading and the port area, in the centre of Lübeck, was evacuated.
Squadron Leader Dinwoodie (while on attachment to the 5140 (Bomb Disposal) Squadron, Royal Air Force Volunteer Reserve) and Corporal Garry Garred were sent to the scene and defused one of the remaining bombs in the batch to discover that a faulty fuse had caused the accident. They rendered the remaining 11 bombs safe when another explosion would have not only killed them but set off the bomb laden trains and devastated the town centre.
Hubert"s medals and some photographs are held by the Royal Air Force Museum at Hendon, London.
