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:
First Battle of Villers-Bretonneux The First Battle of Villers-Bretonneux (30 March – 5 April 1918), took place during Operation Michael, part of the German Spring Offensive on the Western Front. The offensive began against the British Fifth Army and the Third Army on the Somme and pushed back the British and French reinforcements on the north side of the Somme. The capture of Villers-Bretonneux, close to Amiens, a strategically-important road- and rail-junction, would have brought the Germans within artillery-range. In late March, Australian troops were brought south from Belgium as reinforcements to help shore up the line and in early April the Germans launched an attack to capture Villers-Bretonneux. After a determined defence by British and Australian troops, the attackers were close to success until a counter-attack by the 9th Australian Infantry Brigade and British troops late in the afternoon of 4 April restored the situation and halted the German advance on Amiens.
