It was ordered to force the Hallouf Pass. Overnight the 24/25 March 1943, 5 Brigade launched their attack. The pass was opened against severe opposition. This revised plan did not get off to a good start when X Corps HQ and 1st Armoured Division became snarled up with the 4th Indian in Medenine town. The 4th Indian had to hold back, and could not get moving until daylight on the 24th, so they were unable to mount their attack on the Hallouf Pass until that evening.
