 In 462 BC, Argos joined a tripartite alliance with Athens and Thessaly.This alliance was somewhat dysfunctional, however, and the Argives are only thought to have provided marginal contributions to the alliance at the Battle of Oenoe and Tanagra.For example, only 1,000 Argive hoplites are thought to have fought alongside the Athenians at the Battle of Tanagra.
