From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
To political prosecutions after the victory Caesar assigned the narrowest possible limits. No investigation was instituted into the various communications which the constitutional party had held even with nominal Caesarians; Caesar threw the piles of papers found in the enemy's headquarters at Pharsalus and Thapsus into the fire unread, and spared himself and the country from political processes against individuals suspected of high treason. Further, all the common soldiers who had followed their Roman or provincial officers into the contest against Caesar came off with impunity. The sole exception made was in the case of those Roman burgesses, who had taken service in the army of the Numidian king Juba; their property was confiscated by way of penalty for their treason.
Even to the officers of the conquered party Caesar had granted unlimited pardon up to the close of the Spanish campaign of 705; but he became convinced that in this he had gone too far, and that the removal at least of the leaders among them was inevitable. The rule by which he was thenceforth guided was, that every one who after the capitulation of Ilerda had served as an officer in the enemy's army or had sat in the opposition-senate, if he survived the close of the struggle, forfeited his property and his political rights, and was banished from Italy for life; if he did not survive the close of the struggle, his property at least fell to the state; but any one of these, who had formerly accepted pardon from Caesar and was once more found in the ranks of the enemy, thereby forfeited his life.
