The Crusades were nothing more than a series of massacres for a land grab and the Crusaders failed the minute they encountered armies who could actually fight back. Knight Wank is fascinating because it’s almost entirely based on fictional portrayals where the Europeans in tin cans won all the time against evil monsters and savages.
My favorite Crusader story is the one where the Europeans landed and saw a bunch of natives running towards them. The brave invaders slaughtered everyone, and only later found out that they’d killed a local bunch of Christians who thought the knights had come to help them.
