Great captains : A course of six lectures showing the influence on the art of war of the campaigns of Alexander, Hannibal, Cæsar, Gustavus Adolphus, Frederick, and Napoleon

The series begins with a compact yet vivid tour of six commanders whose deeds reshaped the very practice of war. Delivered as a set of lectures in Boston in 1889, the material traces Alexander’s daring conquests, Hannibal’s crossing of the Alps, Caesar’s swift Roman campaigns, Gustavus Adolf’s revival of methodical warfare, Frederick the Great’s disciplined Prussian strategy, and Napoleon’s revolutionary transformations. Interwoven with more than two hundred detailed charts, maps and period illustrations, the narrator paints each battlefield as a living tableau, letting listeners picture the maneuvers that changed history.

In a clear, scholarly voice the speaker outlines the core achievements of each captain, showing how their innovations built the foundations of modern military art. Drawing from ancient eyewitnesses to 19th‑century historians, the lecture offers a concise framework for understanding why these leaders remain benchmarks of strategy. Listeners will come away with a richer sense of how battlefield thinking evolved, all without revealing the later twists of each saga.
