Just saw this amazing good show on Discovery Channel, it's about a decisive battle in history. This time it was Gaugamela, and I have to admit, never seen it so clearly explained. They explained how Phillip built up his army, how Alexander marched through Anatolia, and how the two huge forces met at Gaugamela. In the movie Alexander, you don't get to see what tactic Alexander used. You see his phalanx clash with the persians, with him riding to somewhere. In Battleground: Art of War, experts explained Alexanders tactics. But not only his tactics, also the weapons his army used (explained by Dale Dye).
I'm looking forward to see the episode on Waterloo next week.
