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's absence. As such claims were designed to buttress Welsh genealogy and land claims, they should be viewed with some scepticism. In 388, Maximus led his army across the Alps into Italy in an attempt to claim the purple. The effort failed when he was defeated in Pannonia at the Battle of the Save (in modern Croatia) and at the Battle of Poetovio (at Ptuj in modern Slovenia). He was then executed by Theodosius. 389–406 With Maximus's death, Britain came back under the rule of Emperor Theodosius I until 392, when the usurper Eugenius made a bid for imperial power in the Western Roman Empire until 394 when he was defeated and killed by Theodosius. When Theodosius died in 395, his 10-year-old son Honorius succeeded him as Western Roman Emperor. The real power behind the throne, however, was Stilicho, the son-in-law of Theodosius' brother and the father-in-law of Honorius. Britain was suffering raids by the Scoti, Saxons, and Picts and, sometime between 396 and 398, Stilicho allegedly ordered a campaign against the Picts, likely a naval campaign intended to end their seaborne raids on the east coast of Britain. He may also have ordered campaigns against the Scoti and Saxons at the same time, but either way this would be the last Roman campaign in Britain of which there is any record. In 401 or 402 Stilicho faced wars with the Visigothic king Alaric and the Ostrogothic king Radagaisus. Needing military manpower, he stripped Hadrian's Wall of troops for the final time. The year 402 is the last date of any Roman coinage found in large numbers in Britain, suggesting either that Stilicho also stripped the remaining troops from Britain, or that the Empire could no longer afford to pay the troops who were still there. Meanwhile, the Picts, Saxons and Scoti continued their raids, which may have increased in scope. In 405, for example, Niall of the Nine Hostages is described as having raided along the southern coast of Britain. 407–410 On the last day of December 406 (or, perhaps, 405), the Alans, Vandals, and Suebi living east of Gaul crossed the Rhine, possibly when it was frozen over, and began widespread devastation. As there was no effective Roman response, the remaining
