During early 1944 Digby was a hive of activity with all of the resident squadrons and several visiting squadrons, including several Czech and Belgian squadrons, taken up with training for D-day invasion support. When the invasion took place all of the squadrons relocated to captured airfields in France and Digby became an almost deserted 'ghost town'. All that remained were No. 116 Squadron RAF flying a small number of Airspeed Oxfords in an anti-aircraft training role and two squadrons flying elderly Blenheims for radar calibration off the east coast.
