Army and II US Corps, issuing the appropriate orders to achieve this. Anderson's plan was for the main attack to be in the centre of the V Corps front at Medjez, confronting main Axis defences. However, IX Corps on the right would first attack north-east with, by speed of movement, the intention of getting in behind the Medjez position and disrupting their armoured reserves. II US Corps would make a double thrust: one to capture the high ground on V Corps' left flank and a second toward Bizerte. French XIX Corps would be held back until IX Corps and Eighth Army had drawn in the opposition and then advance toward Pont du Fahs. Battle The Allied forces had reorganised and during the night of 19/20 April, the Eighth Army captured Enfidaville against the Italian 16th Motorized Division "Pistoia", which counter-attacked several times over the next three days and was repulsed and the action at Takrouna also took place. The northward advance of Eighth Army had "pinched out" US II Corps' eastward facing front line, allowing the corps to be withdrawn and switched to the northern end of the Allied front. Arnim knew that an Allied offensive was imminent and launched a spoiling attack on the night of 20/21 April, between Medjez and Goubellat on the IX Corps front. The Hermann Göring Division supported by tanks from 10th Panzer Division penetrated up to at some points but could not force a general withdrawal and eventually returned to their lines. No serious disruption was caused to Allied plans, except that the first attack of the offensive, by IX Corps, was delayed by four hours from 4:00 a.m. on 22 April. On the morning of 22 April, the 46th Division attacked on the IX Corps front, creating a gap for the 6th Armoured Division to pass through by nightfall, followed by 1st Armoured Division, striking east for the next two days but not quick enough to forestall the creation of a strong anti-tank screen which halted their progress. The battle had drawn the Axis reserves of armour south, away from the central front. Seeing that no further progress was likely, Anderson withdrew the 6th Armoured Division and most of the 46th Infantry Division into army reserve. The V Corps attack began on the evening of 22 April and the US II Corps launched their offensive in the early hours of 23 April in
