" It was indeed a strange alteration in the ordinary run of things for Athenians to be fighting a battle on land – and Spartan land too – against Spartans attacking from the sea, and for Spartans to be trying to make a naval landing on their own shores, now hostile to them, against Athenian opposition. For at this time Sparta chiefly prided herself on being a land power with an unrivalled army and Athens on being a sea power with the greatest navy in existence. "
