Trent River
A river in central England.
In the Alliterative Morte Arthure, it was the site of the climactic battle between Arthur and Mordred, which other texts place at Salisbury or Camlann.
According to Malory, in the early days of King Arthur’s reign, most of his enemies lay north of the Trent River. Sir Brastias was appointed warden and was given the job of watching over this area.
