Lorraine Campaign and Operation Undertone both occurred during which war?
Lorraine Campaign Lorraine Campaign is a term used by U.S. Army historians to describe operations of the U.S. Third Army in Lorraine during World War II from September 1 through December 18, 1944. Official U.S. Army campaign names for this period and location are "Northern France" and "Rhineland". The term was popularized by the publication of a volume of the same name by the U.S. Army in 1950. As written by the volume's author:
Battle of Belgium The Battle of Belgium or Belgian Campaign, often referred to within Belgium as the 18 Days' Campaign (French: "Campagne des 18 jours" , Dutch: "Achttiendaagse Veldtocht" ), formed part of the greater Battle of France, an offensive campaign by Germany during the Second World War. It took place over 18 days in May 1940 and ended with the German occupation of Belgium following the surrender of the Belgian Army.
