ABSTRACT
While the campaign in Sicily was still in progress, mainland Greece had gradually slipped back into war. It may seem odd to us that Athenians and Spartans could face each other in battle, as they had done at Mantineia, without there apparently being a state of war between them, but this was the case. Odder still, the Spartans had evidently not even regarded raids on their own territory as a casus belli, two years later, merely issuing a proclamation that their allies could make retaliatory raids (5.115.2).
