after estate; in all a total of 60% of all holdings were waste. It states that 66% of all villages contained wasted manors. Even the prosperous areas of the county had lost 60% of its value compared to 1066. Only 25% of the population and plough teams remained with a reported loss of 80,000 oxen and 150,000 people. The Domesday Book recorded a drastic decline in land values between 1066 and 1086, for Yorkshire, and between 1086 and the 12th century there was a corresponding drop in the value of the land for tax purposes. Independent archaeological evidence supports the massive destruction and displacement of people. The archaeologist Richard Ernest Muir wrote that there was evidence for the "violent disruption [that] took place in Yorkshire in 1069–71, in the form of hoards of coins which were buried by the inhabitants." B. K. Roberts in his book The Making of the English Village, suggests the reason that large numbers of villages have been laid out in regular pattern in Durham and Yorkshire was through a restructuring at a single point in time, as opposed to natural settlement growth. He goes on to say that it is highly unlikely that such plans could have resulted from piecemeal additions and must have been necessary after the Harrying of the North. The dating is thought to be secure as it is known that Norman lords used similar regular plans in founding new towns in the 'plantation' of rural settlements in other conquered parts of the British Isles. However, although the Domesday Book records large numbers of manors in the north as waste, some historians have posited it was not possible for William's relatively small army to be responsible for such wide-scale devastation imputed to him, so perhaps raiding Danes or Scots may have contributed to some of the destruction. It has been variously argued that waste signified manorial re-organisation, some form of tax break, or merely a confession of ignorance by the Domesday commissioners when unable to determine details of population and other manorial resources. According to Paul Dalton, it was questionable whether the Conqueror had the time, manpower or good weather necessary to reduce the north to a desert. It was evident, from the chroniclers, that William did harry the north but as the bulk of William's troops, Dalton suggests, were guarding castles in southern England and Wales, and as William was only
