Battle of Granicus

I was reading one of the campaign book by Osprey.

It was dedicated to one of Alexander's victory over Darius's Persian army.

The most gruesome part of the battle was the annihilation of the Greek Mercennaries, which Alexander slaugthered almost to a man.

The heavy infantry or Mecedonian Phalanx used a 20 foot long sarrisae pike outranged the Greek Hoplite's 7-8 foot long spear. The reach advantage enjoyed by the Macedonians meant that many Greeks were bludgeoned before they could even come into striking distance of the Macedonian heavy infantry.
