 His brother Charles dated his reign in Italy from November 879, so presumably Carloman abdicated that kingdom at the same time as Bavaria.Regarding Carloman's condition, the "Annales Fuldenses" (879) record that he lost his voice, but was still able to communicate by writing.Regino of Prüm, writing in his chronicle for the year 880, recalls that he was "erudite in letters" ("litteris eruditus"), which meant he could write Latin.
