The interesting stuff from the previously mentioned era which contains some details making them more exciting.

These lines tell us about losses.
A.D. 457. ... Hengest and Esc fought with the Britons on the spot that is called Crayford, and there slew four thousand men.
A.D. 603. ... Aeden, king of the Scots, fought with the Dalreathians, and with Ethelfrith, king of the Northumbrians, at Theakstone; where he lost almost all his army.
A.D. 607. ... Ceolwulf fought with the South-Saxons. And Ethelfrith led his army to Chester; where he slew an innumerable host of the Welsh; ... There were also slain two hundred priests, who came thither to pray for the army of the Welsh. Their leader was called Brocmail, who with some fifty men escaped thence. (Oh I remember something similar from Bede here: >>12611)
A.D. 614. ... Cynegils and Cwichelm fought at Bampton, and slew two thousand and forty-six of the Welsh. ("2046" is a very specific number)

Some pursuit, not really relevant for our topic tho.
''A.D. 568. ... Ceawlin, and Cutha the brother of Ceawlin, fought with Ethelbert, and pursued him into Kent.
A.D. 658. ... Kenwal fought with the Welsh at Pen, and pursued them to the Parret.
A.D. 661. ... at Easter, Kenwal fought at Pontesbury; and Wulfere, the son of Penda, pursued him as far as Ashdown.''

This is more like it, still not very helpful with the lack of info. They also look too standardized to base any arguments on them.
''A.D. 514. This year came the West-Saxons into Britain, with three ships, at the place that is called Cerdic's-ore. And Stuff and Wihtgar fought with the Britons, and put them to flight.
A.D. 552. ... Cynric fought with the Britons on the spot that is called Sarum, and put them to flight.
A.D. 752. ... Cuthred, king of the West-Saxons, fought at Burford with Ethelbald, king of the Mercians, and put him to flight.''
