Some time later, being incensed against Attalus, king
of the Asiatic country about Pergamus, Prusias ravaged his territory. When the Roman Senate learned of this they sent word to Prusias that he must not attack Attalus, who was their friend and ally. As he was slow in obeying, the ambassadors laid stern commands upon him to obey the orders of the Senate and to go with 1000 horse to the boundary line to negotiate a treaty with Attalus, who, they said, was awaiting him there with an equal number. Despising the handful of men with Attalus and hoping to ensnare him, Prusias sent the ambassadors in advance to say that he was following with 1000 men, but actually put his whole army in motion and advanced as if to battle. When Attalus and the ambassadors learned of this they took to promiscuous flight. Prusias seized the beasts of burden belonging to the Romans that had been left behind, captured and destroyed the stronghold of Nicephorium, burned the temples in it, and besieged Attalus, who had fled to Pergamus. When these things became known in Rome a fresh embassy was sent, ordering Prusias to make compensation to Attalus for the damage done to him. Then Prusias became alarmed, obeyed the order, and retired. The ambassadors decided that as a penalty he must transfer to Attalus twenty decked ships at once, and pay him 500 talents of silver within a certain time. Accordingly he gave up the ships and began to make the payments at the prescribed time.
