Xerxes Five Million Men

[Aryaman2]

I'm not terribly surprised that their are no Persian records of the campaign. Just as Xerxes would want to inflate his numbers for the ears of the Greeks before the campaign, he would likewise not want to be remembered for a disasterous campaign.

Xerxes commonly executed people who spoke with a tone he disliked. I would not want to be his chronicler. "Oh great king! I have prepared for you a complete record of your gigantic failure against the Yuana." Rather, I suspect he never mentioned it again, and neither did anyone else in his court.

I was thinking of administrative texts, not the kind of records you suggest, because in fact he wasn´t remembered for a disatrous campaign, in the Daeva inscription he says
"King Xerxes says: By the grace of Ahuramazda these are the countries of which I was king apart from Persia. I had lordship over them. They bore me tribute. What was said to them by me, that they did. My law, that held them: Media, Elam, Arachosia, Armenia, Drangiana, Parthia, Aria, Bactria, Sogdia, Chorasmia, Babylonia, Assyria, Sattagydia, Lydia, Egypt, Yaunâ, those who dwell on this side of the sea and those who dwell across the sea, men of Maka, Arabia, Gandara, India, Cappadocia, the Dahae, the haoma-drinking Sacae, the Sacae wearing pointed caps, Thrace, men of Âkaufaciyâ, Libyans, Carians, and the Nubians"
prompted by these discussion, I have been reading quite a bit these days on the Persian Empire, and the impression I get is that it was very unstable, rfiddled with revolts, Darius fought no less than six revolting kings, and he devotes much more room in his Behistum inscription to these wars than to any external wars. Xerxes had to fight many revolts as well, and 2 of them in 481 and 479 BC, during the Greek campaign. It seems unlikely to me he could commit that many resources to that campaign.
