“Murdoch's book makes a valuable contribution to the military and diplomatic relations of the Three Kingdoms with the kingdom of Denmark-Norway and the Scandinavian world. We have gained a better appreciation of how this relationship impacted the British civil wars by supplying experienced soldiers who returned home to fight in those wars, and how Christian IV's failure to honor his promise not to permit arms and munitions to go to the Parliamentarian and Covenanting armies tipped the balance in favor of those forces.”
Roger B Manning, H-Albion Review, May 2006

“One of the main strengths of this study is its base in Scottish, English, Danish, Norwegian and Swedish archives. Murdoch’s book provides a detail-rich picture of the diplomatic and military relations between Denmark-Norway and the Stuart-British state. The combination of varying archival sources and the focus on links between dynastic loyalty and Scottish early modern identity makes this book an original and valuable achievement”
Leos Müller, Scandinavian Journal of History, vol.30, 3/4, 2005

“This book primarily provides a solid presentation of the close diplomatic and political associations between two royal houses on both sides of the North Sea. Murdoch’s study of these relationships has made available to us new and interesting research. His studies will sharpen our awareness as to whom we are dealing with when it comes to giving an account of our historical relationships with the British Isles.”
