[Mayne's] insights into the cultural clash between parts of the reserves and regular officers are interesting and truly original. The book is highly recommended for specialists and informed general readers in Canadian naval history. - Chris Madsen (International Journal of Maritime History, Vol. XIX, No.1) Betrayed has been attractively produced and includes excellent photographs not previously published, extensive endnotes and a comprehensive index which enables the reader to easily zero in on details. Based on careful research and rich in detail, this is a revealing look at how the strains of managing the creation of a modern navy while fighting a vicious campaign proved overwhelming for both the minister and his senior professional advisor. With its rich store of details this book is an essential source of information about internal dynamics within the RCN between 1940 and 1944. Fascinating. - Jan Drent (The Northern Mariner, Volume XVI, No. 4) Mayne's exhaustively researched and crisply written Betrayed is the sorry tale of tensions within the navy and between the RCN and its government.... The cognoscenti will see Mayne's book for the wonderful revelation it is. He has exposed the rich texture of the navy's internal politics and shed light on the machinations of some of the RCN's key officers during the most difficult years of the war. - Marc Milner, University of New Brunswick (H-Canada)
