This Day in History: 1268-06-30

At some stage in 1268 (some sources credit this to 1269 although there is no exact date for either),  John de Warenne, 6th Earl of Surrey and owner of Sandal Castle, was involved in a land dispute with Henry de Lacy, Lord of Pontefract. This quarrel was in danger of escalating into a private war, with both sides raising armies, until King Henry III intervened and the royal justices determined that the pastureland in question belonged to Henry de Lacy.
