The Battle of Thermopylae - Persian View

First of all,they were 1.000 Hellens in the battle:700 Thespians and 300 Spartans.There were more Hellens before the  battle but they were told to leave by Leonidas.The number of the Spartans is in fact very reasonable if we consider the fact that Spartans never had many troops in the battlefield due too their  low population.For example ,3.000 Spartans were a very big force for the Ancient Hellenic data warfare.Moreover ,Spartans never sent huge forces far from their homeland and generally Peloponessus because such an action would weaken homeland defence ,thus permitting the helotes to uprise .And Spartans did not want a possible uprising  of the helotes.The whole Spartiatic System was built in order to create a powerfull war machine,thus preventing the helotes and the perioikoi from a possible uprising.The Thespian numbers are also very reasonable,if we consider the fact that their population was also small.For example the Athenians,with a population of more than 100.000,could have in the battlefield 10 to 15.000 men.How many troops could the Thespians have if their population was much smaller than the Athenian one?Simply ,very few.
