Point taken, Danny. I, for my sins have just attended a 50th anniversary reunion for when our entry was released upon an unsuspecting RAF. Only now, after all those years, have some of the i's been dotted and t's crossed in my mind. It is enough to do your own job without interesting yourself with how others did theirs!
Having said that you paint a vivid picture of the logistical challenge of getting your Squadron set up at Double Moorings and into action in the shortest time possible.
A quick look at Google Maps illustrates the problems, with the two great ports of Calcutta and Chittagong separated by the swamped delta of the Sundarban.
From Chittagong the railway still stops south at Dohazar. In Chittagong (for it extends now to the sea) there is a Double Moorings Police Station but that is all. Presumably your Pied a Terre lay close by. As did the enemy of course, and hence your presence and the need for the move.
