Oh yes, also it was the end of the hundred years war... With France kicking out the British and fully recapturing Bordeaux. They were the first Army to use Cannon as a successful deciding factor in a battle.

Henry VI of England went mad, and the war of the roses ensued. And so, the British were no longer on the continent.

So it wouldn't be historically accurate to have your billmen and longbowmen trapesing all across greater europe as though they were Tango masters. Instead they would be caught up in the local intrigues of the Lancasters and the Yorks.
