An Attic inscription from the early Peloponnesian War records an expedition of thirty triremes, each with five volunteer marines, forty hoplites, ten archers and ten peltasts. Fleets mentioned in Thucydides often averaged more than thirty soldiers per ship, and in fact most of the land battles in the Peloponnesian War were fought against invaders who came by sea. This chapter treats land and sea campaigns in parallel. On campaign Greeks took their armour and weapons, provisions, camping supplies, tools, and medical supplies. In his Acharnians Aristophanes vividly describes what the scene leading up to a fleet's departure would have been like. Greek soldiers also liked camping in sanctuaries, which offered good practical advantages for military camps, since they were prepared to house large numbers of visitors. Naval battles were even rarer than battles on land. The circumvallation sieges were hugely expensive. Greek campaigns simply ended with a general dismissal and a rush to get back pay.
