Food supplies during Persian War

[hoplite14gr]

But where did you get those figures for Greek confederation, are they any more reliable than Herodotus?

The tax and recruting records of the Athenian League survive in plaques now in the National Archaology Meuseum in Athens.
Excavations in Sparta by the British Archological School in 1916 yielded the Patroa Records curved on the homes and verify that raising the eight 600 men Morae was possible. The excavtions of Thespiae in 1961 showed the ancient "Kliri" limits and verified the citys ability to maintain 1000 hoplites in Classical times. Thespiae and Platea both cable of fielding 2000 hoplites were afraid of Theba and were Allied to Athens. That means that Theba to defy all three had at least a force to fight all three simultaneously. The 5th century military catalog of the Aentida tribe in Athens survives in the Museum too and mentions 2000 zevgitae-property owners required to go to war as hoplites. Add their baggage carriers and you have 2000 psiloi at least. That only for one of the 10 Attik tribes.
The catalog of Eteovoutadae was found in a worse state but 300 names
were identified. Ultraviolet light test that are to be done might yield more data. The Neosikoi of Peiraus were excavated and it was found that in the 5th/4th Century they housed 400 trirems. That means 6000 rowers-psiloi and 4000 hoplites-marines needed if there were to be fully manned and that is a conservative estimate.
Kallio of Phokis, the smalest city of the Phokian confederation was excavated in 1987 before coverd by the river Mornos and was found to house approximatly 1000 to 1200 families. Take in to account that these families had more than 2 children usually and that Phokians are mentioned not to have servants or baggage carriers and you have 600 to 1000 combatants only for a small city. The Phokian confederation had 10 cities most of them larger than Kallio.
Kind regards
