After his return to the front, he was wounded in the throat by a sniper's bullet. At 6 ft 2 in (1.88 m), Orwell was considerably taller than the Spanish fighters and had been warned against standing against the trench parapet. Unable to speak, and with blood pouring from his mouth, Orwell was carried on a stretcher to Siétamo, loaded on an ambulance and after a bumpy journey via Barbastro arrived at the hospital in Lleida. He recovered sufficiently to get up and on 27 May 1937 was sent on to Tarragona and two days later to a POUM sanatorium in the suburbs of Barcelona. The bullet had missed his main artery by the barest margin and his voice was barely audible. It had been such a clean shot that the wound immediately went through the process of cauterisation. He received electrotherapy treatment and was declared medically unfit for service.
