The Battle of Kasserine was part of the Tunisian campaign during the Second World War in North Africa.
It was a series of battles that took place around the Kasserine pass, a three-kilometer depression in the Tunisian ridge of the Atlas Mountains. The town of Kasserine is located in western Tunisia.
The Axis forces involved were mainly drawn from the Afrika Korps under Field Marshal Erwin Rommel and the 5th Panzerarmee under Hans-Jürgen von Arnim. The Allied forces were under the command of Major General Lloyd Fredendall of the 2nd US Army Corps.
The battle was the first large-scale encounter between American and German forces in the Second World War. American troops with no experience of fire were clumsily sent into battle by their commanders. The consequences were dramatic, with heavy losses and a retreat of over 80 kilometers from their original positions west of Faïd. In the wake of these events, the American army made a number of changes to the organization of its units and changed its command structure. A few weeks later, in new battles, the American troops prove far more effective.Wikipedia source
