There was a two part Channel 4 docu-drama called "1066: Battle for Middle Earth". I have it recorded but still have to watch it. It sounded strange like about peasants living during 1066, which is supposedly the last time England was invaded. I have no idea why 1688 doesn't count.
I had a go with the flash game. I was about to beat the first battle on my third attempt when internet explorer crashed to a slow grinding halt.
I think it is very much a case of history being written by the victors. The Glorius Revolution was an invasion by 50 ships and 20,000 men. There were two major battles. London was pretty much under marshall law for over a year. I think Brittish patriotism, that is a desire to say we haven't been invaded for nearly 1000 years combined with strong anti catholic prejudice, has kept that version of history alive. William of Orange was invited but I understand it was a group some of whom were within parliment not a parlimentary vote.
