 As Leon's name is not found among the list of either the survivors or casualties of the blockade or its subsequent lifting, this hypothesis makes sense—he was trapped by the blockade but he was neither killed nor freed by the blockade's lifting.McCoy further hypothesizes that the second ship must have been captured by the Spartan fleet, explaining why it never reached Athens.The Spartan commander Callicratidas was noted for treating his captives humanely (a rare characteristic in the ancient world) and likely would not have killed or enslaved the Athenian sailors and their officers, but would have repatriated them after the war ended.
