Oxfordshire
About the year 750, says Plott, a battle was fought near Burford, perhaps on the place still called Battle-Edge, west of the town, towards Upton, between Cuthred or Cuthbert, a tributary king of the West Saxons, and Ethelbald, king of Mercia, whose insupportable exactions the former king not being able to endure, he came into the field against Ethelbald, met and overthrew him there, winning his banner, whereon was depicted a golden dragon; in memory of which victory, the custom of making a dragon yearly, and carrying it up and down the town in great jollity on Midsummer Eve, to which they added the picture of a giant, was in all likelihood first instituted.—Plott, Natural History of Oxfordshire, 1705, p. 356.
