After Gallipoli, Henderson ensured that Sykes was to be an outcast from the service he had helped to create. Brancker wrote to Trenchard on 13 March 1916: 'P .S . What about Sykes as your 4th Brigadier? D . H . [David Henderson] has told me he won' t employ him in any capacity - but we must do something with him. He is awaiting employment now/ 1 Trenchard responded the next day:
