Why do some people think Operation Sea Lion could have worked despite wargame losses?
Short answerThe scenario requires major constraints on Britain; Royal Navy intervention and prepared coastal defenses make a successful landing and lodgement highly unlikely.
NotesEven casualty-heavy simulations can understate the danger to an invasion force once the Home Fleet attacks in the Channel. Night conditions would blunt German air support while favoring British naval gunnery and night-fighting experience. British coastal and Home Guard preparations would make reaching a beach only one part of the problem.
