At the outbreak of the Second World War, Gibbs was still posted at Gosport but, on 1 February 1940, he was promoted
flight lieutenant and then joined
No. 22 Squadron as a flight commander in
Coastal Command, based at RAF North Coates,
Lincolnshire. He then commenced a year-long tour of duty running sorties against enemy shipping off the coasts of Norway and the Netherlands and bombing raids on
Biscay ports. He was promoted to temporary
squadron leader on 1 March 1941, and on 26 September he was awarded the
Distinguished Flying Cross (DFC) for his performance in that role. By then he was in the midst of another six-month stint training pilots. He was promoted temporary wing commander on 1 June 1942. Gibbs flew four sorties from Malta between 22 July and 4 August, twice turning back the convoys. On the final sortie his Beaufort was badly damaged and he crash landed his plane on Malta for a second time. By then Gibbs was exhausted and returned to Britain, and on 18 September the award of the
Distinguished Service Order was gazetted: Gibbs' rank of squadron leader was made fully substantive on 20 November 1942, and backdated all the way to 1 March 1941. He was kept from operational service and was given a role in the
Air Ministry, but by 1944 the strain from his flying days caught up with him and he was invalided out as a wing commander on 24 February. While in the Air Ministry, Gibbs wrote a book on his experiences,
Not Peace but a Sword. The book took in his early life and his war experiences up to his posting in Cairo. The book was a success and he began work on a sequel, but his publishers believed that with the end of the war the book would not be as well received and it was shelved. ==Career in journalism==
