Two different versions of the "Anglo-Saxon Chronicle" record the proceedings of the council. The Peterborough Manuscript (Version E) of the "Chronicle" records the council under the year 785, although the events took place in 787, and states that "here there was a contentious synod at Chelsea and Archbishop Jænberht relinquished some part of his bishopric, and Hygeberht was chosen by King Offa, and Ecgfrith consecrated as king." The Canterbury Manuscript (Version F) has the council under 785 also, and describes the council as "a full synod sat at Chelsey" but otherwise relates much the same events. The historian Nicholas Brooks sees the coupling of the elevation of Lichfield with the consecration of Ecgfrith, who was Offa's son, as significant. He argues that Offa desired to have Ecgfrith consecrated as his successor during Offa's lifetime, but was unable to get Jænberht to agree, and this was another factor in the creation of Lichfield as an archbishopric. Hygeberht consecrated Ecgfrith after Hygeberht's elevation to archiepiscopal status.
