 Tensions sometimes arose between those who had served with British forces during the war, and those who had belonged to the Australian Flying Corps (AFC); the former considered that they were discriminated against when it came to filling senior positions, and came the day Pentland and fellow ex-RAF member Hippolyte De La Rue threw an "uppity" AFC man into a mess fireplace.Deciding that his RAAF career was not progressing, Pentland applied for a short-service commission as a flying officer with the RAF in 1923, which was granted as of 23 April.He journeyed to Britain with new wife Madge (née Moffat), whom he married on 5 March, just before departing Australia; they had one daughter, Carleen, the following year.
