The Southampton Blitz was the heavy bombing of Southampton by the Nazi German Luftwaffe during World War II. It was targeted mainly in the first phase of the Blitz.
Southampton suffered badly from large-scale air raids during World War II. As a large port city on the south coast, it was an important strategic target for the Luftwaffe. There were fifty seven attacks in all, but nerves were frayed by over 1,500 alarms. According to A.R.P. (Air Raid Precautions Department) reports over 2,300 bombs were dropped amounting to over 470 tonnes of high explosives. Over 30,000 incendiary devices were dropped on the city. Nearly 45,000 buildings were damaged or destroyed, with most of the city's High Street being hit. There were reports that the glow of the firestorm of Southampton burning could be seen from as far away as Cherbourg on the coast of France. Nazi publicity declared in propaganda that the city had been left a smoking ruin.
Of the 57 air raids, by far the worst were on 23 and 30 November and 1 December 1940 and these attacks are generally referred to as "Southampton's Blitz". During this three-day period, much of the town centre was destroyed, including All Saints', Holyrood and St. Mary's churches, although St. Michael's escaped with only minor damage, allegedly because the spire was used by the German bombers as a landmark and their pilots were ordered not to hit it. Altogether, Southampton lost seven churches during the blitz, as well as the Audit House, the Ordnance Survey offices and many shops, factories and homes.
