Concept note-1: -German troops overran Belgium, the Netherlands, Luxembourg, and France in six weeks starting in May 1940. France signed an armistice in late June 1940, leaving Great Britain as the only country fighting Nazi Germany.
Concept note-2: -The armistice of June 22 divided France into two zones: one to be under German military occupation and one to be left under nominal French sovereignty. The occupied zone comprised all of northern France from the Swiss frontier to the Channel, along with the entire Atlantic coast to the western end of the Pyrenees.
Concept note-3: -The following analysis concludes that the French lost in 1940 mainly because of three reasons: intelligence failure, operational and tactical inferiority, and poor strategic leadership.
Concept note-4: -Between 9 May and 22 June 1940, a remarkable German assault on north-west Europe, known as the Battle of France, resulted in the capture and subjugation of not only France but three other countries – Luxembourg, the Netherlands and Belgium.
