the US II Corps (Major General Lloyd Fredendall), consisting of the 1st and 34th Infantry Divisions and the 1st Armored Division (although the 34th Division was attached to the British IX Corps to the north). Giraud refused to have the French XIX Corps under the command of the British First Army and so they, along with the US II Corps, remained under command of Allied Force Headquarters (AFHQ). New forward airfields were built to improve air support. The Americans also began bases in Algeria and Tunisia, to form a large forward base at Maknassy, on the eastern edge of the Atlas Mountains, well placed to cut off the Panzerarmee in the south from Tunis and the Fifth Panzer Army in the north. Kasserine Prelude During the first half of January, Anderson had with mixed results kept constant pressure through limited attacks and reconnaissance in strength. Arnim did the same and on 18 January, launched Operation Eilbote I ("Courier I"). Elements of the 10th Panzer and 334th Infantry divisions attacked from Pont du Fahs to create more space in front of the Superga Division and forestall an Allied thrust east to the coast at Enfidaville, to cut Rommel's line of communication. The westward thrust against the right wing of the British V Corps at Bou Arada had little success but further south his attack against French positions around the "hinge" of the Western and Eastern Dorsals succeeded, advancing south to Ousseltia and south-west to Robaa. The poorly equipped defenders resisted well but were overwhelmed and the equivalent of seven infantry battalions were cut off in the mountains. Anderson sent the 36th Brigade to Robaa and requested Lloyd Fredendall to send Combat Command B from 1st Armored Division to Ousseltia, to come under Juin's orders on arrival. Fierce fighting lasted until 23 January but the front was stabilised. The obvious lack of Allied co-ordination led Eisenhower to change the command structure. On 21 January Anderson was made responsible for the co-ordination of the whole front, and on 24 January his responsibilities were extended to include "the employment of American troops". That night, Juin accepted the command of Anderson, confirmed by Giraud the next day but with forces spread over a front and poor communication (Anderson motored over in four days to speak to the corps commanders) the practical difficulties remained. Eisenhower appointed an air support commander, Brigadier General Laurence S. Kuter, for
