Immediately after the war he was the Chief Advocate at some of the war crimes trials held at Labuan (holding the rank of Lieutenant Colonel) and was attached to BBCAU, the British Borneo Civil Affairs Unit which was responsible for the running of North Borneo and other territories after the handover from Australian military control.
[2] In his 1960 book North Borneo, K. G. Tregonning described Maxwell Hall as J. Maxwell Hall, a retired senior officer of the Chartered Company ... one of the very few elderly Englishmen living in the Colony ... the grand old man of the territory.He lives in a two-storied wooden house, sparsely furnished, as befits his Spartan physique, the owner of some fifty acres of land.
He is perhaps one of the most wide-awake and pertinent observers of the North Borneo of today whom it was my privilege to meet.He has written well of the past, in several hard-to-secure books published locally, for he has an historian's bent, and he has contributed numerous articles ...
But all this is relaxation; for he is no ivory tower writer, and it is the problems and the possibilities of the present that interest his wide-ranging curiosity and evoke his keenest comments.
[3]Several of Maxwell Hall's books have been reprinted, most recently Labuan Story: Memoirs of a Small Island near the Coast of North Borneo in 2008.
