Mr Stillwater: "Braveheart" is chock full of historical errors -- which wouldn't be particularly troubling, except that Mel Gibson, I believe, actually
thought that he was being accurate. Yet his depictions of the battles of Stirling Bridge (awful) and Falkirk (godawful) are not just bad history, I don't think they're particularly good cinema either. Better depictions of medieval combat can be found in Kenneth Branagh's "Henry V."
In general, however, movies don't do a very good job of depicting combat, especially pre-World War II combat. Granted, back in the "golden age of Hollywood," there wasn't much of an attempt at accuracy (although the late 20s and early 30s saw some good World War I films), but now there's much less excuse. Yet I continue to see one thing that always bothers me:
Exploding cannonballs.
Prior to the invention of shrapnel in the early nineteenth century, most field artillery pieces fired roundshot, which was simply a solid iron ball. Solid iron balls don't explode -- instead, they work just like bowling balls, flying, bouncing, and rolling, but not exploding . And if you happened to get in the way of one, you might end up like this:
(That's a steel cuirass worn by a French carabinier killed by a cannonball at the battle of Waterloo)
Nevertheless, movies depicting combat in the pre-mechanized era routinely show exploding cannonballs (another Mel Gibson effort, "The Patriot," actually shows roundshot accurately in some of the early scenes, but then reverts to the traditional exploding cannonballs later in the film). I suppose that exploding cannonballs are just more visually -- and aurally -- appealing. But it ain't history.
