Having formed part of British Eighth Army's reserve, the division was moved forward and attached to the Canadian I Corps after the Canadians and Polish II Corps had breached the Hitler Line north of Cassino. After Rome had been taken by the Allies in early June 1944, the division was ordered to move up the Via Casalina to take over the spearhead of the Eighth Army's British XIII Corps. To bring the division up to a full complement of three brigades, the British 24th Guards Brigade was placed under command, an association which lasted to the spring of 1945. The division advanced with the Tiber River to the east and Lake Bolsena to the west at a rate of per day, outstripping their flanking units. On 10 June the Armoured Brigade which was leading the advance, came up against the anti-tank screen of the newly arrived German 365th Infantry Division south of Celleno. For the first (and only) time Brigadier Furstenburg was able to deploy all three of his armoured regiments and his motorised infantry battalion in battle to gain an important victory. Lieutenant-Colonel Papa Brits (Special Service Battalion [SSB]) and Lieutenant-Colonel Bob Reeves-Moore (Imperial Light Horse / Kimberley Regiment [ILH/KR]) received DSOs for their leadership in the defeat of elements of the 365th Division. 11th Armd Bde's success permeated the whole division and on 12 June the division took Orvieto, having advanced in ten days. However, their daily rate of advance had been slowed considerably by consistently being in contact with the enemy.
