2nd RGH reached Egypt in October 1941 as part of British 22nd Armoured Brigade. The unit took part in many of the key battles in Operation Crusader. In subsequent engagements the RGH suffered many casualties and was re-equipped on two occasions. 2nd RGH fought its final action at Battle of Alam el Halfa, on 31 August to 5 September 1942. Expecting to be re-equipped the regiment was instead disbanded with 'F', 'G' and 'H' Squadrons transferred to the 4th Hussars, Royal Wiltshire Yeomanry and the 8th Hussars respectively. HQ Squadron was divided and sent to the 5th Royal Tank Regiment and the 3rd Hussars.
