I don't recall any sallets being visible in AoE II. Or any swordsmen in the intro, but that's been a while. Swordsmen charging reminds me of the Stronghold
intro though. But they're not wearing sallets.
Nice pics on that site though, especially the picture just before the last one.
Edit; wait, you're right. There are sallets in the AoEII intro.
Edit, wait that's a longer version of the intro. Neat.
