I remember reading an account that just prior to the Japanese fleet arriving, Gunner’s Mates were scurrying about to resupply ammo from the freighters to the guns on the other vessels, but the union workers on the freighters refused to unload at 0530 as their union contract didn’t require them to start work before 0800. This prompted a Marine officer to unholster his .45 and reissue to orders to commence their operations, as they wouldn’t be afloat at 0800 otherwise.
Good for the Marine!
