<i>An operations map at RAF Coastal Command Headquarters at Northwood in Hertfordshire, 9 July 1943.</i><br>
Ten million square miles of sea. The vast extent of Coastal Command's theatre of operations is graphically displayed on this newly commissioned 20ft x 30ft map at Coastal Command Headquarters at Northwood, 9 July 1943. From the Arctic Circle to North Africa, from the coasts of occupied Europe to far out into the Atlantic, the Command's areas of responsibility had expanded to such an extent that the existing situation map had been rendered obsolete. Work on the new map was supervised by Coastal Command's Map Officer, Captain J. H. Adam, Royal Engineers.
