First published in 1998, this volume is a record, both by detailed statistical analysis and by personal account, of lessons learned. These lessons are only useful if they are shared to ensure that they are not relearned the hard way. Any soldier or statesman who is involved in Peacekeeping Operations and anyone involved in the future of peacekeeping in the United Nations would be well advised to use this exceptionally insightful and informative work as one of their essential reference books. It contains a rich store of analysis and sober conclusions that makes it an indispensable guide and should serve as a source of inspiration and reflection, but even more it should serve to provide guidance for future action. Biermann and Vadset have made a major contribution to the analysis of UN field operations and an important source book for the study of UN and NATO operations.
