A Naval History of the Peloponnesian War

Marc G. DeSantis offers a comprehensive examination of naval warfare during the Peloponnesian War in this meticulously researched work that fills a significant gap in ancient military history. While numerous studies have explored the land campaigns and political machinations of the conflict between Athens and Sparta, fewer have dedicated themselves exclusively to the maritime dimensions that proved decisive in determining the war's outcome. DeSantis demonstrates that understanding the naval aspects is essential to grasping how this protracted conflict unfolded over nearly three decades.

The book's organizational framework centers on three interconnected elements: ships, men, and money. This tripartite structure proves effective in breaking down the complex logistics and strategic considerations that underpinned ancient naval operations. DeSantis begins with detailed analysis of the triremes themselves, the primary warships of the era. These vessels, powered by approximately 170 rowers arranged in three tiers, represented significant technological and organizational achievements. The author explains the construction, maintenance, and operational capabilities of these ships without becoming mired in excessive technical detail, making the material accessible to readers who may not have specialized knowledge of ancient shipbuilding.

The human element receives substantial attention throughout the work. DeSantis explores the composition of trireme crews, which included not only rowers but also marines, archers, and command personnel. The social dynamics of these crews reflected the broader structure of Greek city-states, with citizens, metics (resident foreigners), and occasionally slaves manning the oars. The author examines how Athens, with its democratic system and large population, could field substantial fleets while maintaining crew quality through experience and training. The contrast with Sparta's approach to naval warfare, initially reliant on allied states and later developing its own maritime capabilities with Persian financial support, receives thorough treatment.

The financial dimensions of naval warfare emerge as perhaps the most revealing aspect of the study. DeSantis meticulously traces the enormous costs associated with building, maintaining, and operating trireme fleets. Athens drew upon the accumulated wealth of the Delian League treasury, originally assembled for collective defense against Persia, to fund its naval supremacy. The author calculates the expenses involved in keeping fleets at sea, including pay for rowers, provisions, and the constant need for ship repairs and replacements. This financial analysis illuminates why the war's outcome hinged significantly on access to resources and why Sparta's eventual alliance with Persia proved so consequential.

The narrative follows the chronological progression of the war, examining major naval engagements and campaigns from multiple perspectives. The Athenian expedition to Sicily receives extensive coverage, with DeSantis analyzing how this disastrous venture depleted Athenian naval resources and manpower. The author details the strategic errors and logistical challenges that doomed this ambitious undertaking, demonstrating how naval superiority alone could not guarantee success without proper planning and sustainable supply lines.

DeSantis also addresses the evolution of naval tactics and strategy throughout the conflict. Early engagements saw Athens leveraging its superior seamanship and ramming techniques, while Sparta and its allies gradually developed countermeasures and alternative approaches. The final phase of the war, particularly operations in the Hellespont and around the grain routes vital to Athens, receives careful examination. The author shows how Sparta's eventual construction of a competitive fleet, funded by Persian gold, shifted the balance and ultimately led to Athenian defeat.

The source material presents inherent challenges, and DeSantis acknowledges these limitations while making judicious use of available evidence. Thucydides provides the most detailed contemporary account, supplemented by other ancient historians and archaeological findings. The author carefully distinguishes between well-attested facts and reasonable inferences, avoiding speculative reconstructions that plague some works on ancient warfare.

This book serves multiple audiences effectively. Scholars of ancient Greek history will appreciate the detailed analysis and comprehensive scope, while general readers interested in military history will find the narrative engaging and informative. The integration of economic, social, and military factors provides a holistic understanding of how naval power functioned in the ancient world and why it proved decisive in the Peloponnesian War's outcome.

DeSantis succeeds in demonstrating that the Peloponnesian War was fundamentally a naval conflict, despite the attention often paid to land battles in popular accounts. The ultimate Spartan victory came not through hoplite prowess but through the construction of a fleet capable of challenging Athenian maritime dominance. This work stands as an important contribution to understanding ancient warfare and the critical role that naval power, properly supported by adequate resources and manpower, played in shaping the Greek world.
