Tacitus' "Agricola" (chapter 28), recounts how a cohort drafted into the Roman army mutinied whilst on campaign in northern Britain (presumably on the west coast) with his father-in-law, the general Gnaeus Julius Agricola (probably in AD 82, although the chronology is disputed). They killed the centurion and regular Roman soldiers based with them for training purposes, then stole three ships and sailed round the northern end of Britain, their hardships including being driven to cannibalism by shortage of food. They finally made landfall in the territory of the Suebi, where some were captured by that tribe. Others were caught by the Frisii and a few survivors were sold into slavery to tell their tale.
