I've been trying to find this out but it has no mention of this. And i wanna know if Edward put up a fight with the Templars just before they killed him like did he take one or a few with him before he was done in?
If not then it surely would be like the edward kenway that we remember from black flag.
His death is depicted in Assassin's Creed: Forsaken, the book written to tie in to the release of ACIII. Edward doesn't exactly go out in a blaze of glory but the book was written before Black Flag was released so I think it's forgivable, and besides, in reality not everyone gets the chance to make a heroic last stand, some people can and do just... die.
