How Britain planned to evacuate its Waterloo standards

Which ship was earmarked to carry the British standards home if the French won at Waterloo?

No single frigate was fixed in advance because the chosen ship and port depended on which escape route remained open.

The provisional order called for the British standards to be taken home if the battle went badly. Frigates waited at several ports rather than one ship receiving a permanent assignment. French cavalry movements could block roads and force the party toward a different harbor. The naval part of the escape plan was therefore deliberately flexible, with the nearest reachable frigate becoming the transport.
