Viking raiders first appeared on the shores of western Europe in the 790s. For the year 793 the Anglo-Saxon Chronicles record, “…terrible portents appeared…and fiery dragons were seen flying in the air…. and the harrying of the heathen miserably destroyed God’s church at Lindisfarne.”, while the Annals of Ulster for 795 describe, “The burning of Rechru by the heathens, and Scí was overwhelmed and laid waste.” These early raids followed a distinct pattern – one or two ships, coastal raids [slide], and hit-and-run tactics.
But in the 830s and 840s, the patterns of raids changed suddenly and dramatically. In Ireland, the Annals of Ulster record for the year 837 “A naval force of the Norsemen sixty ships strong was on the Bóinn, [and] another one of sixty ships on the river Life. These two forces plundered the plain of Life and the plain of Brega, including churches, forts and dwellings. The men of Brega routed the foreigners at Deoninne in Mugdorna of Brega, and six score of the Norsemen fell.” According to the Anglo-Saxon Chronicle, in 838 “In this year came a great pirate host to Cornwall…” The switch to larger raiding parties was swiftly followed by settlement, as in 841 Vikings first set up camp at Dublin. By the middle of the ninth century, it is clear that changes back in Scandinavia were having a direct impact on events in the British Isles, as shown by a takeover at Dublin in the 850s, and the arrival of the “Great Heathen Army” in Anglo-Saxon England in the 860s.
