Cohors Primae Sunicorum

The Sunici or Sinuci were a Germanic tribe who lived on the shores of the Rhine in Lower Germany. The tribe is mentioned by Tacitus in his Histories (IV.lxvi), and it is possible that this infantry unit had originally been formed by the rebel Roman general Julius Civilis during the Batavian revolt of 69AD. It is possible that they formed the original garrison of the Caernarfon fort, and remained there for almost the entire time of Roman rule in Britain.
