When Britain might leave an officer in an allied navy

Would Britain leave an officer in command of a useful allied navy and use the post to train or employ more officers?

Yes, if the ally and assignment remained useful; British officers could stay and others might follow, as service aboard Russian ships illustrates.

Utility and alliance politics would determine whether Britain left an officer in a foreign command. If the navy remained a useful ally, war did not automatically require his recall. The appointment could also give other British officers experience or help the ally operate its fleet. British officers serving aboard Russian ships show that such cross-navy service could be a practical wartime arrangement.
