re: #334 Belafon
Military history question: Have US solders ever refused an order from a president? When is the last time US soldiers refused to do something to where it stopped an operation?
Off the top of my head I would say only places in particularly nasty battles where troops on the field refused to carry out assaults guaranteed to generate heavy losses for no gains. Or they made a very tentative effort and immediately took cover.
American Civil War during Battle of Cold Harbor and some attacks during the Siege of Petersburg. And digging in books I could probably find an example or two from World War II on a much smaller scale (like company level) from the Italian Campaign.
In either case I don’t think this brought a large scale operation to a halt in the early stages - this was after things were underway. And not due to an order being “illegal”, but more due to it being obviously foolhardy or suicidal.
