Why were there problems in the harrying of the north?

The harrying of the North, ordered by William the Conqueror in the winter of 1069-1070, faced several problems primarily due to the fierce resistance from the northern Saxons and their allies, who were determined to oppose Norman rule. The harsh winter conditions hindered military operations, making it difficult for the Normans to maintain supply lines and control over the territory. Additionally, the widespread destruction of land and resources led to widespread famine, which ultimately weakened both the local population and the Norman forces' ability to sustain their campaign. This combination of resistance, environmental challenges, and logistical failures contributed to the overall difficulties in implementing the harrying strategy.
