Hi,

I was always fascinated by this general, who's military skills and tactics are no less than those of Alexander, yet he is by far, the most underestimated, least known general in history.

This general's name is Khalid, Khalid ibn Al-Walid ibn Al-Mughera Al-Makhzumi Al-Qurashi. I have read the wiki entries on him, and that book, sword of allah, but still, none of those give extensive research on his strategies and tactics, which enabled him to proceed undefeated in the huge battles he waged against the persians and byzantines.

Anyone here know of a book or website where I could learn more?
