77 years ago, on the beaches of Dunkirk, the British, French and Belgian soldiers made an unexpected re-embarkation enabling them to escape captivity. The British expeditionary force (BEF), with its 10 motorized divisions, arrived in France in september 1939., was able to evacuate most of its soldiers to Great Britain, but had to ambandon most of its vehicles and tons of equipment. Johann Tytgat, an inhabitant of the region, has travelled relentlessy for more than 30 years on the beaches and the surrounding countryside in search of relics of Operation Dynamo, which took place in may-june 1940. We present these pieces saved from oblivion and sometimes presenting a surptising state for objetcs having spent decades buried in the sand of the beaches. 65 pages.
