Hi Pavros. On Battle of Thermopylae the source says "the sum total of fighting men is two million, six hundred and forty-one thousand, six hundred and ten.". The 5 million are the whole service train, including kitchen personal, etc. --Enric Naval (talk) 15:49, 4 April 2019 (UTC)
- for Battle of Plataea I can't find the exact source, but the figure of 300,000 + 50,000 is commented by scholarly sources such as a history author https://www.ancient.eu/Plataea/ --Enric Naval (talk) 15:57, 4 April 2019 (UTC)
