Note 1400 — Chapter X · THE REIGN OF EADWARD FROM THE DEATH OF THE ÆTHELING TO THE DEATH OF THE KING.[1258] 1057–1066.
Reading edition
John of Salisbury extends the campaign over two years, and Florence places the death of Gruffydd in 1064. But both the Worcester and the Peterborough Chronicles distinctly place the whole story between May and August 1063.
