Input: Question: How many people received the Cross in World War 1? Passage:Petre was awarded the Military Cross on 14 January 1916, and was mentioned in despatches twice more over the course of the year. In May 1916 he contracted typhoid and was sent to India for recuperation. He transferred out of No. 30 Squadron in December, and was awarded the Distinguished Service Order the same month. In February 1917, he was posted to France with No. 15 Squadron RFC, a reconnaissance unit operating B.E.2s. Two months later his youngest brother John, a squadron commander in the Royal Naval Air Service and a Distinguished Service Cross recipient, was killed in a flying accident. Petre subsequently returned to England and took charge of No. 5 Squadron AFC (also known as No. 29 Squadron RFC), a training unit for Australian fighter pilots, particularly those destined for Palestine. He had hoped to command No. 1 Squadron AFC in Palestine but received an adverse report concerning his leadership abilities, and the position went to Williams. Petre was discharged from the AFC as a major on 31 January 1918, to take a commission with the RFC. In April that year, he transferred to the newly formed Royal Air Force, establishing and commanding No. 75 (Home Defence) Squadron.
