Lorraine Campaign and Operation Undertone both occurred during which war?
Operation Undertone Operation Undertone was a large assault by the U.S. Seventh and French 1st Armies of the U.S. Sixth Army Group as part of the Allied invasion of Germany in March 1945 during World War II.
Battle of the Lisaine The Battle of the Lisaine, also known as the Battle of Héricourt was fought from 15 January to 17 January 1871 between German and French forces. The French were led by Charles Denis Bourbaki, and were attempting to relieve the Siege of Belfort. The Germans prepared multiple corps, about 40,000 men, to halt the French advance of about 110,000 men. The Germans had their outer posts overran quite swiftly but the Prussians forced back and counterattacked the French forces, breaking the morale of French troops and leaving them to either die or retreat. In the end their efforts failed, and they were forced to flee into Switzerland where they were all interned soon after.
