For the minor attack in Arakan late in 1942, Irwin and Eastern Army HQ bypassed XV Corps HQ after disagreements with the local commander, Bill Slim, and took command of the operation. The attack failed, with severe effects on Allied morale and prestige. On 6 April 1943, Irwin gave a press conference in which he criticised the equipment, training and motivation of the Allied armies in India. Although his observations were admitted to be largely correct, Irwin's refusal to admit that any blame attached to himself and his staff was resented. He was relieved of his appointment and returned to Britain on sick leave.
