The morning of September 2nd was calm, and at an early hour Octavian’s workmanlike ships stationed themselves about three-quarters of a mile from the mouth of the Gulf of Ambracia, where they were watched by the eyes of both armies. They were formed into three divisions, the left wing being commanded by Agrippa, the centre by Lucius Arruntius, and the right wing by Octavian. At about noon Antony’s huge men-o’-war began to pass out from the harbour, under cover of the troops and engines of war stationed upon the two promontories. Octavian seems to have thought that it would be difficult to attack them in the straits, and therefore he retired out to sea, giving his enemies the opportunity of forming up for battle. This was speedily done, the fleet being divided, like Octavian’s, into three squadrons, C. Sossius moving against Octavian, Marcus Insteius opposing Arruntius, and Antony facing Agrippa. The sixty Egyptian ships, under Cleopatra’s command, were the last to leave the Gulf, and formed up behind the central division.
