Cohors I Batavorum milliaria c.R. pf

Cohors [prima] Batavorum milliaria civium Romanorum pia fidelis ("[1st] 1000 strong cohort of Roman citizens Batavi, dutiful and loyal") was a Roman auxiliary cohort of infantry.

Military diplomas
The unit is attested on several military diplomas for the provinces of Pannonia, Pannonia Superior and Dacia Porolissensis.
