After Eighth Army's victory at Wadi Akarit, 128th Bde was part of the force sent by First Army to cut the retreat of the Axis forces, even though Army HQ did not consider it completely ready for battle. As a preliminary to the main attack on the Fondouk Pass, it was tasked with capturing and holding crossings over Wadi Marguellil and then the high ground beyond, which it successfully achieved on 7/8 April. First Army began its final offensive on Tunis (Operation Vulcan) on 22 April. 46th Division attacked with strong artillery and tank support towards some hills near Sebkret el Kourzia in an effort to crack open the position for the armour to pass through. In the event the armoured formations had five days' hard fighting before they could get through. Axis air attacks were maintained until 25 April, doing considerable damage, but tailed off thereafter.
