From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
This took place before there was a formal breach with Rome; when the breach at length ensued, friend and foe expected a Macedonian landing in Lower Italy. Since 539 a Roman fleet and army had been stationed at Brundisium to meet it; Philip, who was without vessels of war, was constructing a flotilla of light Illyrian barks to convey his army across. But when the endeavour had to be made in earnest, his courage failed to encounter the dreaded quinqueremes at sea; he broke the promise which he had given to his ally Hannibal to attempt a landing, and with the view of still doing something he resolved to make an attack on his own share of the spoil, the Roman possessions in Epirus (540).
Nothing would have come of this even at the best; but the Romans, who well knew that offensive was preferable to defensive protection, were by no means content to remain--as Philip may have hoped--spectators of the attack from the opposite shore. The Roman fleet conveyed a division of the army from Brundisium to Epirus; Oricum was recaptured from the king, a garrison was thrown into Apollonia, and the Macedonian camp was stormed.
Thereupon Philip passed from partial action to total inaction, and notwithstanding all the complaints of Hannibal, who vainly tried to breathe into such a halting and shortsighted policy his own fire and clearness of decision, he allowed some years to elapse in armed inactivity.
