Default RN Vessels as Floating Fortresses Against Seelowe


I recently came across this passage in a thesis:-

Warships that were incapable of escaping out to sea were to be
provisioned for at least seven days and moored in the Sound to defend
Plymouth against a frontal attack from the sea. HMS Adventure (four 4.7"
guns and Pom-Poms), HMS Esperance Bay (seven 6", two 3" guns) and HMS Isas
(four 4.7" and two 0.5" guns) were all designated as floating fortresses in
September 1940. Other vessels that could not be employed as floating
batteries were prepared for sinking in positions that would prevent access
to the docks and basins.
The information seems to originate within ADM199/1201 Immobilization of Ports. Dunbar-Nasmith, 7 September 1940. Not having direct access to this file, can anyone shed any further light on what other 'floating fortresses' were envisaged?

PS: I'm assuming that HMS Isas is in fact HMS Isis!

I came across this in reference to HMS Centurion:
According to R.A. Burt's 'British Battleships of World War 1', 'in June 1940, she (HMS Centurion) was rearmed with a miscellaneous collection of guns for the anti-invasion forces...'.
I have not found any further information on this topic.

Armed merchant cruiser ESPERANCE BAY, carrying ten million pounds in gold, was bombed and badly damaged shortly after leaving England at 1250 in 49-30N, 6-40W, one hundred miles west of Land's End.
Lt Cdr H. Close RNR, and six ratings were killed.
Destroyer VANOC and Canadian destroyer RESTIGOUCHE escorted the merchant cruiser. Dutch tug ZWARTE ZEE was sent.
Destroyer VANOC and tug ZWARTE ZEE was reassigned when it was found the armed merchant cruiser could proceed on her own to Plymouth with the gold

Well now I know why the AMC was in Plymouth, as it had been undergoing repairs after the above event.

Still no further with any other specifics on the wider issue though
