However, after Eustace's sudden death in August 1153, it appears that a more formal agreement was written at Winchester in November 1153, signed later at Westminster.
Izgledno je da su se strane nakon iznenadne Eustahijeve smrti kolovoza 1153. sporazumjele i napisale sporazum u Winchesteru studenoga 1153., kojeg se kasnije potpisalo u Westminsteru.
