The RNAS and RFC carried out bombing raids on German bomber airfields at St. Denis-Westrem and Gontrode, forcing the squadrons to relocate to Mariakerke and Oostakker, with the staff headquarters moving to Ghent. The next raid against England was carried out on 29 October, when three aircraft set out, two diverting to Calais because of the weather and the third dropping its bombs on the Essex coast. The following night a big raid was mounted, the bomb load including large numbers of a newly developed incendiary bomb. 22 Gothas took off, of which over half released their bombs over Kent, with little effect other than the destruction of a gasometer in Ramsgate. Bombs were dropped on the eastern suburbs of London but many of the incendiaries failed to ignite and five aircraft crashed when attempting to land.
