Abstract
Given the increasing interest in ancient military history it seems timely to set Perikles' Peloponnesian War policy of avoiding major land battles in the context of the military options available and how these worked in practice. I should, however, sound one note of caution from the start. My discussion represents a modern assessment of the defence strategies and options available to Athens in 431. While Perikles and his successors undoubtedly considered how best to fight the war, it would be misleading to even imply that their thought processes involved conducting an analysis anywhere near as sophisticated as the one which follows. Quite simply they lacked the theoretical concepts and even the technical vocabulary to do so. There was no history or tradition of staff college appreciations in fifth century Athens and no body of technical or theoretical military literature, and it seems clear that even experienced and successful commanders did not look at war with the same sort of theoretical constructs which we take for granted today.
