490 Marathon-definitely the Athenians. The Spartans were delayed by an important religious festival (the Carneia) which they had to observe as they were very pious re the gods. They turned up 2-3 days later, but missed all the action!!
The inter-war years: The Athenians were much more active in preparing for a second, and what was, they believed, an inevitably greater invasion. Themistocles was especially instrumental in warning the Athenians and other Greek states about this, even sending to the Delphic Oracle for a prediction. The Spartans were more concerned about defending the Peloponnese and their own alliance system and planned to build a wall across the Isthmus at Corinth. The Athenians pushed for a pan-Hellenic congress to discuss the defence of Greece which resulted in 480 at the Isthmus and resulted in the formation of The Greek League/Hellenic League.
The following is worth considering:
"Although the Greek states of the mainland admired Athens
for her victory at Marathon, they looked for leadership not
to her but to Sparta. Athens had no following and her
neighbours were hostile. Spartra was the head of a great
Alliance: among her followers she counted the neighbours
of Athens-Megara, Aegina and Thebes-and she had a
practical and probably a formal alliance with Athens herself.
Her influence was thus paramount among the Greek states.
At the same time her prestige as a military power and as
leader of a military Alliance stood very high since the crushing
defeat of Argos at Sepeia.....The whole problem of any
organised resistance to the Persians herefore centred on
Sparta." (N.G.L. Hammond "A History of Greece to 322 B.C."
(P. 223)
Athens (sea) and Sparta (land) were made joint commanders of the Greek forces, but Sparta was hegemon (supreme commander)
The first naval battle, at Artemisium, was commanded by the Spartan Eurybiades who had no knowledge or experience of naval warfare. It seems likely that Themistocles really called the shots. A storm and lots of confusion did not result in a clear victory
At Thermopylae, the Spartans under Leonidas and a small contingent of mixed local Greek states held up the Persian advance for 3 days, but were annihilated. This did give some time
however, to the Athenians to evacuate their city and surrounding areas, so the sacrifice was a significant achievement.
The turning point was Salamis, tactically the brainchild of Themistocles and the Athenian naval commanders. The large Ath. navy (some 200 triremes) was supplemented by contingents from other allied states from the mainland and the islands and Asia Minor. It turned the Persian advance back to central Greece. The Spartans and their Peloponnesian allies were massed at the isthmus to defend the narrow land bridge into the Peloponnese.
The final land battle at Plataea was between the remnants of the Persian army (still overwhelmingly large) and a combined hoplite force of Greek allies. Some states did not show up. Athens did not distinguish itself in this battle as their generals quarreled with the Spartans, led by Pausanias, and did not co-operate in the lead-up and early stages of the battle. Their conduct came close to jeopardising the overwhelming success of the battle. The Spartans were outstanding and showed why they were the leading military power in Greece. This victory drove the Persians from Greece.
The final encounter at Mycale, off the coast of Asia Minor where the Greek navy, predominantly Athenian and Ath. led routed the Persians and drove them away from the Ionian cities. The spartans did not participate as immediately after Plataea, they returned to the Peloponnese to secure consolidate their leadership leadership there.
I think one could conclude that both Athenians and Spartans played important roles in different ways in different battles. The more intangible things to consider would be:
*Willingness to defend Greece
*ability to see the bigger picture and put the defence of all
of Greece before the interests of a particular polis or
region
*willingness to put differences and animosities aside for the
greater good
*willingness to co-operate and consult
*initiative in foreseeing future dangers and preparing for it
etc...etc...
