On May 14, 1940, after the German Operation "Fall Gelb" the Netherlands surrendered to Germany with the exception of the south westerly province of Zeeland. From the Netherlands only a few military succeeded in escaping to Great Britain. When the battle was also lost in Zeeland, a large number of soldiers escaped to Great Britain via the Belgian and French ports Brest and Cherbourg. Next to troops of the regular forces, part of the ground personnel of the flying schools Haamstede and Flushing succeeded in fleeing to Great Britain.
