Addendum to "The Babylonians"

Going over Herodotus for next week's entry, I notice I missed an important line when writing up yesterday's entry on the Babylonians, to wit:

With [the Assyrians] were the Chaldeans.
- The Histories,   VII.63

This indicates that, yes, there WERE Babylonians in the 480 invasion.  He doesn't elaborate on their costume or weapons, although he may do so elsewhere and I should continue checking.
