This is a fascinating account of the secret wartime efforts of the people of Yorkshire, including details of coastal and inland defence systems, special units trained to resist a German invasion and RADAR sites.

Meticulously researched by author Ron Freethy and told in his highly readable style, the book charts the experiences of those working in Yorkshire's hush-hush occupations, such as silk map making, radar components and machine guns, showing how vital Sheffield's steel industry was to the war effort.

Yorkshire: the Secret War will appeal to anyone interested in Yorkshire's military history, and particularly its all-out determination to play an important role in the defeat of the enemy in World War II.
