Which part of racedo's diatribe are you with, PN? He has successively suggested that (UK?) Commanders were only there because of accident of birth and by the same token could not be removed, to a different position that their subordinates were not willing to risk their careers in challenging their decisions, to yet another position that decisions taken at Board level are subject to Group Think, even though all are opposed (bar 2) to what the Group Think states. I am not persuaded by any of those scenarios.
We are not looking here at a tactical command. If the Convoy Commander orders it to scatter, it scatters. What we are looking at is a supposed best course of action after careful lengthy deliberation at the Admiralty. Of course the resultant order is sent in the name of the FSL, but the assumption of those receiving it is that is an overall agreed position and not contrary to it.
You cannot have a situation where one man can imperil thousands of others and millions of tons vital supplies simply because he is unwell, and thus rejects the advice given him by everyone else (bar 1). This is exceptional and requires exceptional response, rather like when Air Marshals issue illegal orders. Your duty then is to kiss goodbye to your career and report them to their superiors. Whether you do or not is the measure of you, not of them.
