This is a list of the recorded wars and battles between the Anglo-Saxons who later formed into the Kingdom of England and the Britons; the pre-existing Brythonic population of Britain south of the Antonine Wall who came to be known later by the English as Welsh. The list begins after the Adventus Saxonum in c. AD 446 (when the Anglo-Saxons are said to have first arrived in Britain) to the late Middle Ages when Wales was eventually subdued and annexed by England. The list is not exhaustive but seeks to note the significant campaigns and the major battles.
Pagan Germanic tribes who have colonized parts of the eastern and southern coasts of Britannia attack the Britons (which the Anglo-Saxons dub "Wealsc") in a series of coordinated uprisings. Additional reinforcements from Old Saxony, Angeln, Flanders and Jutland make landings and through conquest and treaty occupy large areas of eastern and south eastern Britain.
Pagan Anglo-Saxon tribes conquer southern Britain capturing London, Colchester, Silchester, Chichester, Winchester, Grantchester, Leicester, Gloucester, Cirencester, Bath, York, Lincoln and Canterbury among other places. Later in the century Angles defeat the northern Britons and colonize the north eastern coast.
