This unique volume presents an edited selection of works upon the laws of armed conflict by the late Professor Colonel G. I. A. D. Draper, OBE. Professor Colonel Draper was a central figure in the analysis and dissemination of the humanitarian laws of armed conflict in the English-speaking world. He had a wide practical and academic experience of the subject including service as a prosecutor at the Nuremberg trials. His work covered not only the contemporary substance of the law but also its moral, ethical and political context, the pressures upon its development and its potential for further positive, and other, development. This edited collection presents a very significant part of Professor Colonel Draper’s work, including many pieces which are no longer readily accessible or have never before been published, with modern commentary referring to developments which have occurred since his death. The late Professor Colonel’s work is an important scholarly contribution to the subject and also retains a very great degree of modern relevance, including comment upon such issues as war crimes and appropriate responses to them. The Editors present this collection as both an important scholarly and practical resource and a fitting tribute to one of the great twentieth century contributors to this area of law.
