A typescript personal account by Wilkins of the origins of radar, the work of Sir Robert Watson-Watt, the Tizard Committee, and the setting up of a coastal chain of radar stations which were important during the Second World War Battle of Britain. Wilkins was asked to write his account by John Ashworth Ratcliffe as a counter to the official account by Watson-Watt "Three steps to victory; a personal account by radar's greatest pioneer" (Odhams, London, c 1957).
