Advanced Landing Grounds (ALGs) in Normandy

Location of the ALGs

The two Tactical Air Forces depended upon fighters, fighter-bombers, reconnaissance aircraft and night fighters being over the battlefield most of their mission time. To do so required that the bases they operated from were as close to the "bomb line" as possible. Quickly-prepared bases close to the front were called "Advanced Landing Grounds" or "ALGs." In 1943 and early 1944, many ALGs were built throughout southern England, and as soon as the Normandy beachhead was opened up, over thirty were built in France. The location of USAAF ALGs (denoted by the letter "A" and a number) and RAF ALGs (denoted by the letter "B" and a number) are shown in the diagram below:
