Raids by Saxons, Picts, and the Scoti of Ireland had been ongoing in the late 4th century, but these increased in the years after 383. There were also large-scale permanent Irish settlements made along the coasts of Wales under circumstances that remain unclear. Maximus campaigned in Britain against both the Picts and Scoti, with historians differing on whether this was in the year 382 or 384 (i.e., whether the campaign was before or after he became Caesar). Welsh legend relates that before launching his usurpation, Maximus made preparations for an altered governmental and defence framework for the beleaguered provinces. Figures such as Coel Hen were said to be placed into key positions to protect the island in Maximus' absence. As such claims were designed to buttress Welsh genealogy and land claims, they should be viewed with some scepticism.
