Military Commands in Late Roman Britain


        A.) The Duke of Britain (Dux Limitum Britannicarum).

            14,000 infantrymen.
            900 horsemen.
            36 forts on the Antonine and Hadrian Walls.


        Listed below are the commands and forces in the notitia Dignitatum as being under the command of the dux britannicarum , or Duke of the Provinces of Britain, at least in the late 4th century, early 5th century AD. Since the notitia is a complex document which has undergone a great many changes through history, there are a number of entries that are plainly wrong or confused. Where the veracity of the information can be checked against other literary and epigraphic sources, it proves to be generally reliable however, these inconsistencies aside. Unfortunately it does not give a complete picture of forces in the north at this time, as there is not a perfect match between the archaological evidence for the occupation of forts with the notitia evidence.
