World War II: France's zone libre is occupied by German forces in Case Anton.
Zone libre
The zone libre was a partition of the French metropolitan territory during World War II, established at the Second Armistice at Compiègne on 22 June 1940. It lay to the south of the demarcation line and was administered by the French government of Philippe Pétain based in Vichy, in a relatively unrestricted fashion. To the north lay the zone occupée, in which the powers of Vichy France were severely limited.
Case Anton
Case Anton was the military occupation of Vichy France carried out by Nazi Germany and Fascist Italy in November 1942. It marked the end of the Vichy regime as a nominally independent state and the disbanding of its army, but it continued its existence as a puppet government in Occupied France. One of the last actions of the Vichy armed forces before their dissolution was the scuttling of the French fleet in Toulon to prevent it from falling into Axis hands.
