I did a little bit more on Scythia. I have little doubt that this refers to SS Scythia, torpedoed off Algiers on 23rd November 1942. I downloaded file BT 389-26-147 from The National Archives, London, some 13 pages on cards. After being torpedoed she was berthed in Algiers harbour. The cards are all over the shop, but a close examination shows that she entered the harbour on 25th November.
She was designated as a Naval Accommodation Ship on 7th December 1942. The card says "To be used as Naval Accommodation Ship at Algiers, DSTO Algiers 1427/7 Dec."
Scythia sailed for Oran on 10th January 1943, where she arrived on 14th January. She was repairing at Oran on 25th January, and sailed from Oran on 31st March, arriving at Gibraltar on 12th April 1943. The card says "DD Gibraltar cap comp(?) 15/5."
Humphries' records show "Duty" on/at Scythia from 1st-5th January. A guess on my part, but he was possibly on board checking out equipment etc. as she was being readied to move to Oran.
I too have found nothing on a "Fort Beri." I wonder if the spelling/interpretation of the writing is correct? I recently downloaded a war diary from TNA that was entitled "Hanlot Base Remount Depot." "Hanlot" turned out to be "Hautot."
