Very interesting video I found while browsing Youtube.

I'm not sure exactly how accurate it is, but it's from a Spanish movie and shows the clash of two pike units in the 30 Years War. Before the infantry melee, the unit gets pummeled by artillery and stands off a cavalry assault.

What I though was kinda nifty was how when the ranks of pike meet, they don't smash into one another, but kind of fence a bit at distance. Then a few men with short weapons dash in under the pikes and start slashing and stabbing.

Again, I don't know how much of this is accurate and how much is show biz, but it's worth a watch.

If anybody can critique it for accuracy, that would be nice as well.
