I submit the following from a great reference I use:
14 Feb 1945, Tunesia, 4:00 AM;
General Jurgan von Arnim's forces launch a violent attack on Allied troops of the First Army, which are moving into Tunesai from the west.
The plan of attack is Rommel's:
It provides for a break through of the Allied line in the direction of Kasserine and Tebessa, followed, if successful, by an advance on Bone and Constantine.
General Anderson, commanding the Allied army, had at his disposal the British V Corps in the north, the French XIX Corps in the center and the American II Corps, including the 1st A/R, 1st A/D, in the south.
The Axis forces included a part of von Arnim's Fifth Army, and, in the south a part of Rommel's Afrikakorps.
Von Arnim's action was successful.
The Germans took Sidi Bon Zid, and cut off the Americans holding Djebel Lessouda in the north and Djebel Kasaira in the south.
15 Feb 1943, Tunesia..
Units of the Afrikakorps attacked in the southern sector of of the line and take Gafsa.
An American counter-attack by the US 1st Armored Division in the Sidi Bou Zid sector was repulsed, but during the night the Americans manage to withdraw from Djebel Lessouda unharmed.
