Gabriel expands upon the groundbreaking work of B. H. Lidell-Hart's Great Captains by offering detailed portraits of six great captains of the ancient world who met the challenges of their age and shaped the future of their societies, and civilization itself, through their actions. He analyzes the lives of Thutmose III of Egypt, Sargon II of Assyria, Philip II of Macedon, Hannibal of Carthage, Scipio Africanus of Republican Rome, and Caesar Augustus of Imperial Rome for the lessons contemporary leaders, particularly military leaders, can learn.

While all were great military men, with the exception of Caesar Augustus, they were also great political leaders who, in this capacity more often than through their feats of arms, shaped their societies. All were educated men, and all possessed the quality of imaginative reasoning. A provocative analysis for scholars, students, and general readers of military history and the ancient world. Military personnel will find the parallels to current military organization and thinking particularly valuable.
