Alexander's Intelligence System

Abstract

It has frequently been recognized that the collection and use of accurate military intelligence was of fundamental importance for the success of Alexander's campaigns. No intelligent strategic or tactical decision can be made by any commander without advance knowledge of an enemy's location, strength, his capabilities and weaknesses, and the geography of the projected campaign. However, an analysis of the procedures Alexander used to obtain and evaluate intelligence has never been undertaken. This neglect is probably the result of the scattered and unsatisfactory nature of the references to Alexander's intelligence procedures in our ancient sources.
