Sorry for going offtopic but I found the title "Ghosts of Alexander" mildly amusing because as a race Pukhtoons didn't exists back then. Alexander fought Hindu King Puru (Porus) before the advent of Islam. According to the North Indian folklores, Alexander didn't defeated Porus but got injured during the battle and left along with his Army, thus war remained inconclusive. Some Indian historians too believe that since the Western historians at that time were Hellicentric, the actual report never found it's true place and the Western version became the only version.
