On 10 May 1940, Goetsenhoven was attacked by the
Luftwaffe as part of the initial
German attack on Belgium, killing several personnel and destroying some aircraft, and was seized by the
Wehrmacht a few days later. The Goetsenhoven squadrons hastily retreated to other airfields with their remaining planes. They were eventually evacuated to France. During the occupation of Belgium, the airfield was used by the Luftwaffe as a reserve airfield; no Luftwaffe units were stationed there. In late October 1944, the airfield was attacked by
United States Army Air Forces (USAAF)
Ninth Air Force Martin B-26 Marauder medium bombers and
Republic P-47 Thunderbolts with 500-pound general purpose bombs, unguided rockets, and .50 caliber machine gun sweeps to ensure that any German forces at the base were neutralized.
Allied ground forces moved into the Tienen area around 20 October and the first American combat engineer units arrived at the airfield shortly afterward. The USAAF IX Engineering Command 862d Engineer Aviation Battalion laid down a 3600' all weather
pierced steel planking runway at Goetsenhoven, and rehabilitated some of the buildings for use by combat units. On 26 October, the airfield was declared operationally ready and was designated as
Advanced Landing Ground "Y-10", also being known as "Le Culot/East Airfield". Shortly after the airfield opened, the 9th AF
371st Fighter Group moved there with P-47 fighters and remained until 20 December. Once the American combat units moved out, Goetsenhoven became a transport airfield for
C-47 Skytrains, which flew frequently in and out of the American controlled airfield, supplying the front line forces with the necessary materiel to support their advance. On return flights to the rear area, casualty evacuation was performed by the transports. At the end of the war, Goetsenhoven was returned to Belgian control by the Americans on 25 June 1945. ==Postwar use==
