How did Nicias fail to convince the Athenian assembly that the Sicilian Expedition was a strategic error? His arguments, while valid and logical, are not sufficient to win over the assembly to undo their vote of war. Not only does Thucydides have incomplete information about these events, but Thucydides’ prior knowledge of Nicias’s failure colors the way he reconstructs Nicias’s ineffective arguments against war.

If Thucydides did not know of perhaps the most compelling reason
