In spite of their numerical inferiority the Dutch Armed Forces did achieve some success against the Luftwaffe, which lost 350 aircraft in the conquest of the Netherlands, although many of these were lost to anti-aircraft fire and crashes at improvised landing fields in the Netherlands rather than due to action by Dutch fighter-aircraft. The cost was high – almost 95% of the Dutch pilots were lost. In recognition of their actions Queen Wilhelmina granted the highest Dutch military decoration, the "Militaire Willemsorde" (MWO), to the Army Aviation Brigade collectively.
