ALG A-21 C history:

ALG A-21 C is originally an Emergency Landing Strip (ELS) coded E-1 (E for “Emergency”) and built the day after June 6, 1944 by sappers of Lieutenant Colonel John J. Livingstone, who work under enemy fire. On June 9, 1944 at 18:00, a C-47 transport plane can land on the runway: the evacuation of seriously wounded, taken care of in the 13th Field Hospital also located in Saint-Laurent-sur-Mer, can begin.

Quickly renamed “ALG A-21 C” (C for Cargo), this aerodrome (the first to be fully operational during the Battle of Normandy) evacuated 15,000 wounded from June 9 to August 25, 1944 to hospitals located in England.
