Page "Ajaccio" Paragraph 14

Marbeuf also offered Charles-Marie one appointment for one of his sons to the Military College of Brienne, but the child must be under 10.

There is a dispute concerning Napoleon's age because of this requirement ; the emperor is known to have altered the civic records at Ajaccio concerning himself and it is possible that he was born in Corte in 1768 when his father was there on business.

In any case Napoleon went to Brienne 1779 – 1784.
