Four days after the official conversion, 10th Armoured Brigade received its first equipment. The War Diary records: 'The first two tanks arrived, two Vickers Medium tanks dated 1923 and 1924. These were not in going order, and were practically useless'.[7] The brigade got its first cruiser tanks – four Covenanters – on 1 December,[8] and over the next two years received a trickle of widely varied tanks, including Cruiser Mk I, Cruiser Mk II, Cruiser Mk IIa, Covenanter and Crusader cruiser tanks, Valentine and Churchill infantry tanks, and later some Sherman Vs.[9]
In May 1942, 10th Armoured Brigade left 42nd Armoured Division and the motor battalion was withdrawn. Then, on 25 July, the brigade was redesignated 10th Tank Brigade. The role of a tank brigade was infantry support. On 17 October 1942, the brigade was placed under the command of 48th (South Midland) Division, which was a reserve formation, and was given the role of holding and training reinforcements for other tank units.[10]
The brigade maintained Lancashire Fusilier traditions, initially wearing the regimental badge on the black beret of the RAC,[4] and celebrating Minden Day on 1 August 'in traditional style. Each unit held a ceremonial parade and march past'.[12] When rumours began to circulate that 10th Tank Brigade was scheduled for disbandment, Members of Parliament for the Lancashire towns complained about the loss of their TA battalions.[12] In August 1943, a recruiting team persuaded about 60 other ranks of the brigade to volunteer for the Parachute Regiment if the brigade disbanded.[12]
The brigade moved to Wensleydale in September, with Brigade HQ at Bedale,[13] but shortly afterwards the impending disbandment was confirmed, the brigade came under direct War Office control,[14] and the regiments began to dispose of their equipment to other regiments. Brigade HQ and Signals were disbanded with effect from 25 November and completed by 16 December.[15]
Of the three tank regiments, 108 and 109 RAC (formerly 1/5th and 1/6th Lancashire Fusiliers TA) were "dispersed", while 143 RAC (formerly the hostilities-only 9th Lancashire Fusiliers) was disbanded.[15] Of these battalions, only the 5th Battalion, Lancashire Fusiliers was reconstituted in the Territorial Army after the war.[16]
