The Spartans took a big chunk of cash from the Persians and used it to build a rival navy, then hired the rowers at a much higher rate than the Athenians could pay. Ended the Peloponnesian War in a trice. They should have had a Reserve Clause.
Yes I have read Thucydides & VDH’s book on the subject “A War Like No Other”. Rowers showed as much loyalty as Alcibiades.
Weren’t the Athenian rowers part of a collegium\guild or whatever the Greek equivalent was?
