"Spain was invading Europe, I think it was the eighty years war, they got as far as Belgium and documented some pretty horrific atrocities, killing and raping civilians and burning whole towns. They let a couple of survivors go to spread fear. Didn't work. By the time they got to the Netherlands people were pissed off with the invaders. It was also nearly winter. The Spanish tried to march on a Dutch city and the Dutch said, screw those guys and flooded the plains between the army and the city. The Spanish didn't fancy wading and drowning so they hopped on their support ships and tried to approach the city from the water except they messed up and by the time the got there the water had frozen and the ships were useless. They formed up on the ice and began once again to march on the city. By this time the Dutch had set boobytraps everywhere, lots of the invaders pitched into freezing water, and where they did manage to engage the Dutch in direct combat, the Dutch turned out on ice skates and fought back, often quickly skating into range, taking a shot and then skating back to safety. The Spanish didn't know what the hell was going on and got their @$$es kicked by an army on skates. I really want to see this movie one day but I doubt anybody would believe it."
