Note 22 — Chapter III · Criticism of The Accepted View
Reading edition
Or possibly 28; see von Domaszewski, “Zur Geschichte des Rheinheeres,” Röm.-Germ. Korrespondenzblatt, 1910, on the date of the establishment of the twenty-first and twenty-second legions. There is some question about the exact date at which the increase in the size of the legions was made (see the literature cited by Gardthausen, Augustus, II, p. 775), but that does not affect our argument. See above note 7.
