German invasion of Luxembourg
The German invasion of Luxembourg was part of Case Yellow (), the German invasion of the Low Countries—Belgium, Luxembourg and the Netherlands—and France during World War II. The battle began on 10 May 1940 and lasted just one day. Facing only light resistance, German troops quickly occupied Luxembourg. The Luxembourgish government, and Grand Duchess Charlotte, managed to escape the country and a government-in-exile was created in London.
