Flotilla is Dis-established

The formation has not survived the post-war restructuring of the Royal Navy.

Seymour has been given to the refashioned Fourth Destroyer Flotilla.

Botha has gone to The Nore, probably in Reserve, while Swift has been placed in Reserve at Portsmouth.

Miranda is at The Nore with a "miscellaneous" assignment.
