In the US II Corps area, the plan of attack is changed after another fruitless attempt by Task Force Benson of the 1st Armored Div to break through enemy positions blocking the Gabès road. The second phase of the attack, which is to secure a pass between Djebel Chemsi and Djebel Ben Khëir for the armor, is to begin at once, although the enemy still retains Hill 772 on Djebel Berda and Hill 369 and the pass north of it on Djebel el Kreroua. Task Force Benson goes on the defensive. The 1st Div continues its efforts to clear the southeast tip of Djebel el Mcheltat. The 9th Div is concentrating on Hill 772, which must be cleared before operations can be continued against Hill 369. In the Maknassy area, Combat Command A, 1st Armored Div, continues its diversionary attack on Djebel Djebs. The Southeast Algerian Command's camel troops are maintaining liaison with the British 8th Army in the Kebili area.
