The most influential account of the career of Alexander the Great was penned by Cleitarchus in the decades after Alexander's death. Most of the surviving ancient texts on Alexander were based upon his work, but every copy of the original was destroyed in antiquity. Now the entire book is being revived in an exciting reconstruction based upon an in-depth analysis of the surviving ancient works that it inspired. This volume presents the section dealing with Alexander's campaigns in Afghanistan. It became a blood-soaked slog against unrelenting opponents who adopted the same guerrilla resistance as is seen there today. Alexander was also beset by internal dissension with treason and plot within his own camp. How he coped with these dual challenges, through ruthless force in combination with conciliatory gestures, still offers useful lessons in strategy. Alexander was uniquely successful in establishing the region's rule by Greek kings for the next few centuries. A date for Alexander's accession is also proposed.
