Operation Market Garden came to a standstill in September. During the winter of 1944/1945, the frontline had reached the Dutch-German border but was making little progress, with the fighting pushing it just a metre at a time. On the Allied side, the deployment of equipment and the dedication from the men were tremendously high. This required efficient organisation and support for the troops on the frontline from the air force. This need for air support was the reason why Allies constructed airfields in the liberated areas behind the frontline following the Normandy Landings on 6th June 1944.

These new airfields enabled the Allies to move troops more quickly, and gave them a place to station their fighter planes. At the end of December 1944, the Royal Engineers and Pioneer Corps were ordered to build B.89 here, in Mill: the 89th airfield to be constructed after D-Day.

When it became clear that there was going to be a large allied offensive in the area along the Dutch-German border in February 1945, the completion date for the airfield in Mill was brought forward. This gave the men only a matter of a few weeks to construct this enormous airfield, with the harsh winter weather to contend with as well. The beginning of February marked the start of these large allied offensives: their 8th February deadline?
