Military operations began in 31 BC, when Octavian's general Agrippa captured Methone, a Greek town allied to Antony.
The Genoese fleet under Paganino Doria captured the Venetian fleet under Niccolò Pisani at the harbour of Sapienza or Porto Longo, near the fortress of Modon (mod. Methoni) in southern Greece.
But the death of Venantius, occurring suddenly at Methone, Achaia, prevented the pious travellers from going further.
We also know that in 359 BC, Argeas, former enemy of Amyntas (father of Philip II of Macedon), or according to certain historians (Diodorus, XVI, 3, 5.) one of his sons, had just obtained a fleet of 3,000 hoplites from the Athenians: The troops disembarked and then set up in Methoni.
Rumney was exported from Methoni in the southern Peloponnese (one English source calls it Rompney of Modonn) and perhaps also from Patras and other ports.
The fleet left the Dardanelles on 1 July, and crossed the Aegean Sea to the port of Methone, where it was joined by the last contingents of troops.
