Operation Lüttich was a codename given to a German counter-attack during the Battle of Normandy, which took place around the American positions near Mortain from 7 August to 13 August 1944. (Lüttich is the German name for the city of Liège in Belgium, where the Germans had won a victory in the early days of August 1914 during World War I.) The offensive is also referred to in American and British histories of the Battle of Normandy as the Mortain counter-offensive. Read the whole story: https://en.wikipedia.org/wiki/Operation_Lüttich
