Being ignorant of these matters I presume a list/timetable of sailings still exists.
from this I might be able to shortlist any sailing that might give me the information I'm searching for.
Firstly, have these survived in any form- if they ever existed?
If there are surviving records where and how would you access them? digitised?
As I have only just scratched the surface on this- I presume the lists of foreign ports calling at several uk ports will have the internal travellers listed.
I suppose a bit of background could help you to to help me.
Sidney had seen service in the Boer war.On his way back he reached the end of his service. They disembarked and went to Fermoy barracks and soon absconded.
I don't know if this was commonplace or not but I'm wondering could he have gone back on the ship that carried the rest of his unit(presumably he knew the details)? Would/should this have been recorded in his record- which it wasn't. Would they have listing for who was onbtroopships?
