site landed in the mud of the river. However, 42 were killed and 161 injured, many when the railway bridge, under which workers were still making their way to air raid shelters, received a direct hit, as did one of the already occupied bomb shelters beneath a railway embankment, where 24 were killed and 75 injured. Also many nearby houses were destroyed with terrible loss of life. Works manager H.B. Pratt was wounded and badly traumatised by the attack. Two days later, on 26 September, sixty Heinkel He 111s of KG55 escorted by 60 Me 110 fighters of ZG26 attacked from 5.45pm onwards in two waves. The incoming attack was detected early, with factory sirens sounding just after 4pm, which gave the workers ample time to evacuate. In spite of anti-aircraft fire more than 70 tons of bombs were dropped, with seven bombs directly hitting the Woolston works and one hitting the Itchen works. The factory buildings at Woolston were so badly damaged that they were never rebuilt, and the ruins were at one stage used to train commandos in street fighting. Both prototypes of the Type 317 bomber and three complete Spitfires were destroyed, while over 20 Spitfires were damaged. Luckily, several of the critical production jigs had already been moved to other sites and the remainder of the most important precision machines were virtually undamaged. One bomb scored a direct hit on a bomb shelter, but it was unoccupied as – after the experience of previous raid – many of the employees had run well away from the factory area. Even so, 55 were killed and 92 injured. Complete dispersal of production By this time the new factory at Castle Bromwich was producing Spitfires, but with a desperate need for more aircraft Lord Beaverbrook, the Minister of Aircraft Production (MAP), visited Southampton and immediately ordered a complete dispersal of Supermarine's facilities. The top floor of the Polygon Hotel in the centre of Southampton was immediately requisitioned by the MAP for the use of Supermarine's production team. Work immediately began by the production team under the leadership of the company's works engineer, Leonard G. Gooch on a dispersal programme. Gooch's impressive efforts meant that by December 1940 he formally replaced Platt as Works Manager. The replacement of Pratt is also believed to have been partially orchestrated by Beaverbrook in retaliation for Pratt's refusal prior to the air raids to
