the Athenian general Philocles persuaded the Athenian assembly to go on record as allowing trireme captains to chop off the right hand of all prisoners taken at sea. Presumably his idea was that only such tough measures would stop the desertions of imperial seamen tempted to join the Spartans by promises of higher pay. Philocles himself was known to have ordered captured oarsmen thrown overboard on the high seas, which explains why the Spartans executed almost every Athenian they got their hands on after their final victory at Aegospotami—a staggering number that might have reached 3,500.
