soon as they heard of the defeat of the former in Thessaly, they entered
into negotiations with Perseus, and at the same time sent ambassadors to
Rome, who complained, that in consequence of the war between Perseus and
the Romans, the navigation and commerce of Rhodes was greatly injured,
their island deprived of provisions and other necessaries, and the customs

After the defeat of Perseus, they ceased to remonstrate, and became

his whole force by sea and land against them: they were not however
dismayed, but placed a firm reliance on their skill in maritime affairs.
They divided their fleet into three squadrons: one drawn up in a line

protecting the port. The Rhodians gradually retired before the enemy, till
they came close to the mouth of the harbour: Mithridates in vain
endeavoured to break their line, and force an entrance; in all his attempts
