Sorry, I've been on holiday and just noticed this thread. The very first word seems to be the most important... IF. I am not too sure how the combined French and Spanish fleets could have landed 100,000 men complete with horses, artillery, ammunition and supplies without having a fantastic dock facility to disembark from. Would this magically appear somewhere on the south coast allowing the allies a fairly straightforward advance on London? Also the Royal Navy would probably have to be off sailing around the globe just for the sheer hell of it to allow an invasion. You have to bear in mind the there have been NO successful invasions of these islands since 1066 and there is a very good reason for that. It's not any easy thing to do! The Royal Navy, at that time, did rule the waves and the English south coast and it's harbours were more than reasonably safe from interference by any enemy. There may have been plenty of plans for invasion, planning is one thing, but nobody actually tried it. If it was as easy as being suggested then there is a good chance that it may have been attempted, it wasn't. I appreciate that this is an Alternate History website, but the alternate bit should have a degree of realism, not be fantasy based.
