Hi

I am researching a cousin who was probably conscripted to the RE and sailed to Gibralter in 1940. He was a 2nd Lt. His occupation was a civil engineer. Does anyone know what he would have done there? I have read a bit about the tunnelling and the underground "city' created there, but wondering about his job. Possibly regiments 178-180?
His record shows in 1955 he was probably still conscripted in the Territorial Army in the Royal Regiment of Artillery.
thanks for any help. (I am in New Zealand0
