The Battle of Pylos, fought at sea and land, took place in 425 BC during the Peloponnesian War at the peninsula of Pylos, on the present-day Bay of Navarino in Messenia, and was an Athenian victory over Sparta. An Athenian fleet had been driven ashore at Pylos by a storm, and, at the instigation of Demosthenes, the Athenian soldiers fortified the peninsula, and a small force was left there when the fleet departed again. The establishment of an Athenian garrison in Spartan territory frightened the Spartan leadership, and the Spartan army, which had been ravaging Attica under the command of Agis, ended their expedition (the expedition only lasted 15 days) and marched home, while the Spartan fleet at Corcyra sailed to Pylos. Demosthenes had five triremes and their complements of soldiers as a garrison, and was reinforced by 40 hoplites from a Messenian ship that happened to stop at Pylos. In total, Demosthenes probably had about 600 men, only 90 of which were hoplites. He sent two of his triremes to intercept the Athenian fleet and inform Sophocles and Eurymedon of his danger. The Spartans, meanwhile, had 43 triremes and a large land army.
