Roman Military Campaigns – Gnaeus Julius Agricola ( AD77/8 -83/4)

We are extremely fortunate in the case of this man in that his son-in-law was none other than Gaius Cornelius Tacitus, the prolific Roman writer and historian, who recorded in The Agricola the biography of this great man, which remains the only surviving biography of a Roman general outside of the imperial families. This document records the campaigns not only of Agricola himself, but of all the men who preceeded him in the post of pro-praetorian governor of Britain, albeit in an abbreviated form.
