Legio X Gemina

The legion was reconstituted in 42 BC and fought for Augustus (commonly referred to by Octavian by historians), Lepidus and Mark Antony in the Battle of Philippi against the murderers of Caesar.

In 70, after the Batavian rebellion was suppressed by the new emperor Vespasian, X Gemina was sent to Batavia in Germania Inferior to police the lands and prevent new revolts.

From 71 to 103, the legion was stationed at the base built by II Adiutrix near Oppidum Batavorum, the present day Dutch city of Nijmegen.

For this reason, the Tenth — as well as the other legions of the army, I Minervia, VI Victrix, and XXII Primigenia — received the title Pia Fidelis Domitiana, "faithful and loyal to Domitian", with the reference to the Emperor dropped at his death and subsequent damnatio memoriae.

A garrison of Legio X GPF was found in the Czech Republic in Roman fortress in Moravia (Mušov) X Gemina supported its governor, Septimius Severus, in his bid for purple, and many men of the legion went to Rome to become part of the Praetorian Guard of the new Emperor.

The titles Antoniniana (awarded by Caracalla or Elagabalus), Gordiana (by Gordian III), Deciana (by Decius), Floriana (by Florianus), and Cariniana (by Carinus) were short-lived, however, and dropped after the death of the Emperor.

At the time in which Notitia Dignitatum was written (late 4th century), the first detachment of Decima Gemina was under the command of the Magister Militum per Orientem, and was a comitatensis unit.
