If memory serves correct (HA!) this was reenacted in the miniseries Shaka Zulu years ago in a convincing if lurid (Hollywood) fashion. Small wonder the Zulus under Shaka and his successors were so rightly feared by their immediate neighbors,..
Excellent memory *Luoshangzhi! I had forgotten all about that one.
But then again if "My" memory serves, (I see your Ha and raise you a "Hm Hmmm") If thats the one I recall, it was released during my highschool years (Yes kids, we had "talking pictures" back then!)
Unfortunately I did not appreciate it enough to watch it. At that time (HS) I was studying more uhm, 'biology'. (wink, wink, nudge, nudge)
However, the information I was refering too, I believe 'was' from the History channel. They had a series entitled "Soldiers" or "Warriors", something to that effect. Sorry friends, its been at least 10+ yrs., so dates are a bit fuzzy. It really was a great series, each week it covered anything from Native American Commanchee warriors to those of the Hawaii Islands to units of the ECW to modern warfare tactics/ equipment.
