So many knights were killed that this battle became popularly known as the Battle of the Golden Spurs - a reference to the spurs taken from the dead knights on the field. Kortrijk (or Courtrai) does have a nice museum that covers details of the battle, and I encourage you to visit it if you're ever near there.
While this is a nice, historic Belgian town, the battlefield today is little more than a city park; but the battle itself is a lesson that the little guy can win, if disciplined and determined. I always take something from that.
