"This is a book of history, specifically of Muslim military history. It deals with the life and campaigns of one of the most remarkable soldiers the world has ever known-Khalid bin Al Waleed, an all-conquering hero who never knew the meaning of military defeat. Seeking clarity for the layman as well as the professional soldier, I have avoided technical terminology and tried to maintain a simple style.

A good deal of what appears in this book is not generally known to the public; but every incident, every circumstance is historically correct. Every move, every duel, every blow, every quoted statement is taken from the accounts of the early historians. In the interpretation of the facts, I have at times had to rely on judgement, particularly with regard to the description of the battles; but I have tried to be as objective as possible. In my account of the battles and my description of the events which occurred in those early, fateful years of Islam, I have given credit to the enemies of Islam when they deserved it (and this was often); and I have pointed out the mistakes of the Muslims (though these were few)."  By A.I.
