I’m in the process of transcribing the No.1 (Airship) Squadron Routine Orders Part II (1912-1914) into an Excel spreadsheet. There is a list of men, with dates, either going on leave or furlough (spelt furlo in Routine Orders).
I thought furlough and leave were the same thing, but there is obviously a slight difference between the two?
Does anyone know what that difference is?

Thanks in advance.
