In the US II Corps area, the 1st Armored Div continues its futile efforts to take Djebel Naemia, where the Germans are build up strength. The 1st Div contains 2 strong enemy thrusts toward El Guettar. There are heavy losses on both sides. The Southeast Algerian Command is meeting strong opposition as it continues to move forward south of the US II Corps.

In the British 8th Army area, the XXX Corps withdraws the Wadi Zigzaou bridgehead during the night under cover of artillery fire. The Indian 4th Div begins operations to clear the Médenine-Hallouf-Bir Soltane road during the night. The X Corps headquarters and the 1st Armored Div move out after dark to join up with the New Zealand Corps in preparation for an assault against the enemy's western flank. The New Zealand Corp is still being held up in a bottleneck between Djebel Tebaga and Djebel Melab.

For the moment the Germans halt the American advance near El Guettar and Djebel Naemia, but 10th Pzr Div loses heavily in trying to exploit early successes. Already the American tactical performance is much improved. Montgomery decides to transfer his main attack to the Tebaga Gap and therefore sends 1st Arm Div and Gen Horrocks over the Matmata Hills to join the New Zealanders. This move is slowed by traffic problems.
