One of the newcomers to Warby’s Squadron was 20-year-old Canadian William Keir Carr, known as Bill. When he reported to Warby, he found him in a revetment shack, stretched out on a table drinking tea surrounded by airmen who quite obviously worshipped their 25-year old boss. Bill soon recognised Warby’s leadership as inspirational. He was no longer the loner of his early days in Malta. Warby personally flew all the missions targeting the heavily defended island of Pantelleria. Keith Durbridge, one of 683 Squadron’s pilots, later remarked Warby was the only pilot he ever heard of who was fired at by anti-aircraft batteries from "above". Warby’s photography allowed Allied planners to pinpoint every defensive location which were then subjected to a merciless bombardment. As soon as the invading force was sighted, Pantelleria’s garrison surrendered. Warby also undertook the photography of the landing beaches for the Allied invasion of Sicily. He covered all four missions from a height of 200-feet. Hugh O’Neil flew the fighter escort and commented that Warby was undeterred by the flak, simply smoking a large cigar as he went about his task. ‘The vertical and low oblique photographs of the coastline, which General Patton considered “essential to the success of the operation”, were of the highest value to the whole force.’ All had been taken by Warby. The C-in-C Middle East, General Harold Alexander, signalled Malta asking that Warby be thanked personally. In late July, Warby was awarded a Bar to his DSO.
