A couple of links relating to the Battle of Brunanburh*
1. Ian McDougall’s 1995 article: ‘Discretion and deceit: a re-examination of a military stratagem in Egils saga’.
This discusses, among other things, the various theories surrounding the location of the battle. I picked it up via a post at Medievalists.net.
Update, 25 July 2013: Until recently, the full text of McDougall’s article was online at De Re Militari (The Society for Medieval Military History), but the DRM website is currently being re-vamped so the article is temporarily unavailable.
2. An audio file of the Old English ‘Brunanburh’ poem, recited by Professor Michael Drout. It can be heard at his website Anglo-Saxon Aloud (along with audio of numerous other OE poems).
*This famous battle was fought by Athelstan, king of the West Saxons, against a coalition of Vikings, Scots and Britons in 937. Its location is unknown. I used to think it was most likely fought at Bromborough in Cheshire, but now I’m inclined to look much further north.
