How escaped French destroyers could serve Britain

How would French destroyers that escaped to Britain in 1940 be used?

They would serve as convoy escorts and probably operate heavily in the Mediterranean, creating a celebrated Free French legacy.

The Royal Navy's shortage of escorts would prevent it from being precious about assigning these ships. Convoy duty would come first, followed by frequent Mediterranean service where their French identity might also create tactical uncertainty. Their crews would acquire a powerful Free French reputation through continued combat. Post-war France would likely commemorate their officers and ships as national naval heroes.
