By nightfall 1st Arm Div has nearly reached the Tebaga Gap. Von Arnim is worried about this attack and the threat from the Americans at Maknassy, and therefore begins to pull his German and Italian infantry out of the Mareth Line.

In the US II Corps area, the 1s Armored Div's attack against Djebel Naemia at first makes some progress, but the gains cannot be held. Maintaining pressure on the 1st Div on the hills southeast of El Guettar, the enemy forces the units of the 18th Infantry to give ground on the northeastern part of Djebel Berda. Since no reinforcements for this position are available, the 18th Infantry defense force is ordered to withdraw from Djebel Berda.

The US II Corps receives a new directive from Gen Alexander, calling for a broadened offensive and is reinforced for this purpose by the 34th and 9th Divs. The 34th Div is to conduct a limited offensive for the Fondouk Gab from Sbeïtla. The 9th Div, less the 60th Regimental Combat Team, and the 1st Div are to open a gap southeast of El Guettar for the passage of the 1st Armored Div. The 1st Armored Div is to break off its offensive in the Maknassy area and leave a small holding force there in order to drive on Gabès.
