Second World War bomb discovered in Portsmouth Harbour

Second World War bomb discovered in Portsmouth Harbour

16 November 2016

Today’s evacuation of Portsmouth Historic Dockyard following the discovery of a 500lb Luftwaffe bomb is an inconvenience, but we should perhaps reflect on the extraordinary ferocity of the wartime attacks on Portsmouth whose lethal legacy initiated it.

Between July 1940 and the end of May 1944, the city suffered sixty-seven air raids, in which 1,320 high explosive bombs, 38,000 incendiaries and thirty-eight huge parachute mines were dropped. 930 people were killed, and as many as 10 per cent of the city's 63,000 homes were destroyed.

117 people died in one of the worst raids, on 24 August 1940, including eight children watching a matinee in the Prince’s Theatre. In the Dockyard, a direct hit on an underground vault being used as an air raid shelter near the Block Mills killed twenty-six workers and injured many more.

On 8 March 1941, a parachute mine fell directly on to one of the 250-ton dockyard cranes, where it remained dangling from its parachute, banging against the capstan machinery on the dockside beneath it, a lucky escape for the cruiser HMS Berwick which was in dock alongside. Two days later, on 10 March, a bomb hit an air raid shelter in the Royal Navy Torpedo School, HMS Vernon, (now Gunwharf Quays shopping centre), killing twenty-five men. This was the last of the heavy attacks, although nuisance raids and later ‘flying bomb’ attacks plagued the city until almost the end of the war.
It’s also worth mentioning that some ordnance is nearly 500 years old. During the Mary Rose excavation both wrought iron and cast bronze guns were discovered. Some of these were loaded with their shot and even the powder. But luckily the 437 year old powder was no longer active when found.
