[cf. L cataracto, waterfall].
Decisive 6th-century battle in British history in which Saxons crushed British (i.e. Welsh) chieftains. The site of the battle is coextensive with the ford of Catterick Bridge on the River Swale, 2.5 miles SE of Richmond, Yorkshire; remembered in the well-known Welsh poem, the Gododdin (6th cent.), attributed to Aneirin.
