The final phase of the Tunisian campaign began on 6 May with Operation Strike directed towards Tunis. After the infantry had broken into the Axis defence lines 7th Armoured Division was directed to dash ahead and break through the inner defences before the enemy had time to man them. 22nd Armoured Bde set off at 10.30 after 4th Indian Division had secured a vital knoll, and headed for the high ground. However the advance got slowed up, and by 17.00 7th Armoured had settled into a position about beyond the infantry. Next morning 22nd Armd Bde engaged a few scattered tanks and 88mm guns and disposed of them by 14.00. At 15.15 7th Armoured was ordered to close in on Tunis. Armoured car patrols reached the city centre at 15.40, closely followed by 1st RTR with 1/7th Bn Queen's from 131st Bde. They quelled any scattered resistance, secured all important building and bridges, and restored order. All remaining Axis forces in Tunisia were rounded up and surrendered unconditionally on 13 May.
