My father, Eric Deverill, worked as an engineer at Annesley from his mid teens until he retired.
During the war, while still working at Annesley he served as a Captain in Miltary Intelligence under the immediate command of Colonel Chaworth-Musters at Annesley Hall.
A secret underground bunker was established near Newstead and Annesley pits where it could command views of Annesley Hall (which would most likely have been occupied following invasion).
I am aware of other colliery men who where members of the secret cell. Does any of this information ring any bells with other Annesley/Newstead readers?
