In November, 159 bombers from "Luftflotte" 2 and 3 bombed Southampton destroying much of the city. Bombers attached to the air fleet led attacks on Birmingham, part of 357-strong force. Incendiaries started fires that were visible from 47 miles (75 kilometres) away. The air fleet was involved in attacks on Liverpool (324 bombers). Over 20–22 December 205 and 299 bombers struck the city. The bombing, on targets such as Liverpool, were not followed up the next night, giving the city, inhabitants and defences time to recover. Ministry of Home Security Herbert Morrison warned that morale in the city might crumble under sustained bombing—he did report 39,126 grt of shipping had been sunk, 111,601 grt damaged. Half the berths were out of action and unloading capacity was reduced by 75 percent.
