The Flemish Farm

The Flemish Farm is a 1943 film that follows a Belgian pilot who was originally attached to the Belgian Air Force Regiment. As Germany was invading that country in 1940 the commander, Major Lessart, orders the Regimental Standard be buried so as not to fall into enemy hands. While the regiment watch it being ceremoniously buried at sea with the last post, etc, the flag is in fact secretly being buried on the farm where they’re operating their Hurricanes from. Shortly afterwards a handful of pilots in the last four Hurricanes fly off and the rest of them at the farm are left behind.

Later in England those pilots who escaped have joined the RAF and one of the pilots comes to see his old Flight Commander to tell him he’d actually buried the flag in the farm paddock, and it still existed. He proposed they go back to Belgium in a clandestine fashion and retrieve it. However the younger pilot was killed so just the Flight Comander goes. After much hassle and a long journey he brings it to England.

Now the whole reason I’m writing this is I have the film and at the beginning it states that it is based on a true story but names had been changed for security (it was made in wartime). I have tried to find out more about the real story this is based on, but have never been able to find out the true circumstances or people involved.

Does anyone know facts about the supposed real story? Was the flag really buried and later retrieved? Where is it now? Who were the people involved?
