Daglish's books led to the presentation of a paper, by invitation, on the subject of Operation Bluecoat to the international conference ‘The Normandy Campaign 1944: 60 Years On’ held at the History and Governance Institute at the University of Wolverhampton in the summer of 2004. Another paper entitled ‘Operation Bluecoat – a victory ignored?’ was later published with other essays taken from conference papers in ‘The Normandy Campaign 1944: 60 Years On’, by Routledge in 2006.^[7]
