A cohors peditata quingenaria consisted of about 500 soldiers.
Notes on verification
Confirmed by Wikipedia and an independent specialist source, with additional context showing 'quingenaria' was a nominal designation (~480 actual troops) rather than an exact count, consistent with the 'about 500' phrasing in the claim.
