operated over southeast England. London was again the principal 
      objective although Birmingham and Liverpool were also subjected 
      to a minor scale of attack. Mine-laying was sus %pected in the 
      Thames Estuary and off the East Coast. In the London area 5 factories 
      engaged on war work were hit, but at none of them was the damage 
      serious nor is production likely to be affected to any extent. 
      Serious damage was done to the Treasury building and a bomb fell 
      in the courtyard of the National Gallery. An aerodrome was attacked 
      just after dusk and 5 dispersed Fighter aircraft were ds3~aged. 
      Although bombing in the outer suburbs was widespread, damage 
      and casualties reported are not serious. At Birmingham minor 
      damage is reported from six factories but in no case does it 
      appear likely that output will be seriously affected. Prom Merseyside 
      no serious damage is reported and, although high explosive bombs 
      fell in the airport at Rochester, little damage was done.
