On his ‘rest tour’, Warby promptly had his posting changed from No. 233 Squadron, a training unit, to No. 2 Photo Reconnaissance Unit (PRU). When 2 PRU acquired two Beaufighters, the squadron commander, Squadron Leader Hugh McPhail, had them stripped of guns, cannon, and other equipment, to increase their speed and ceiling. By mid-November, Warby was on operations over Crete. Both aircraft were then detached to Malta. Within 24-hours, Warby was revisiting his old haunts including Tripoli, all of Sicily, and Southern Italy, once again under the direct control of Air Vice-Marshal Hugh Lloyd. Lloyd later described Warby as, ‘the absolute king of photographic reconnaissance, the pearl of the Mediterranean.’ ‘Warby’s luck’ continued when he was attacked by a Hurricane. He said it was rather a poor show as he only found one bullet hole in his aircraft’s left aileron.
