During the early part of yesterday enemy activity was confined 
      to isolated raids. In the latter part of the morning 2 raids 
      of about 30 and 50 aircraft attacked Folkstone and balloon barrage 
      at Dover. These raids were intercepted. Towards evening about 
      250 enemy aircraft approached London from the Thames Estuary, 
      but turned off and appeared to make for military objectives and 
      aerodromes in southern Essex. Considerable damage was caused 
      to public services and to a railway embankment in this area, 
      but casualties were very few. Another 250 converged on Portsmouth 
      where the chief attack was on Fort Cumberland, considerable structural 
      damage was done to buildings, water mains, and electric light 
      supply; four officers and four other ranks were killed, and three 
      officers and ten other ranks wounded. In other districts a military 
      camp was bombed causing some casualties and minor damage, and 
      an aerodrome at which 3 aircraft were damaged. These raids were 
      also intercepted by our fighter squadrons.
 
      
 
 
Last night enemy bombing activity was widespread and about 
      300 airplanes were operating. Warning in London lasted for 6 
      hours and bombs were dropped chiefly in northern suburbs.
