The research is outstanding.

Navy News, July 2010

For the first time printed in a single volume, this book despatches from the military and naval commanders. Focusing on the aircraft attacks on Kirkenes and Petsamo, the latter in Finland by aircraft from HMS Furious and HMS Victorious in August 1941, and the combined operations raid on the Lofoten Islands in March and Vaagso in December the same year.

The Bulletin of The Military Historical Society

There are great many interesting, fresh and well-captioned photographs. I must recommend both Geirr Haarr books as the definitive work on the invasion of Norway. He must be congratualated in setting out this very complex struggle in a logical, detailed and even-handed manner.

Warships International Fleet Review

Those who have read Geirr Haarr's previous volume, which covered the German assault on Norway in April 1940, will need little introduction to this mastery sequel which describes subsequent events at sea and on land. This is a book about the projection of power from the sea, it's possibilities, strengths, weaknesses and the potential need for protracted operations after the initial, successful, amphibious assault.
The author writes with unique insight and gives due weight to Norwegian perspectives, absent in previous accounts, that show how Allied fears that 'fifth-columnists' or 'Quslings' were present in large numbers complicated the relationships between some British senior officers and their Norwegian counterparts.
This is an outstanding work of scholarship with significant contemporary relevance and a very readable account of how predecessors coped in the opening stages of an unexpected war that will be interest and value to a wide readership. I whole-heartedly recommend it.

Geirr H. Haarr's new two-volume work is a tremendous accomplishment. The Norwegian researcher strives for comprehensive coverage, his concise yet thorough treatment of the aerial dimension is especially noteworthy. This second volume paints on a broader canvas than the first, detailing the Allied expeditionary response and the naval, air and ground battles throughout the country. The volumes are very well illustrated with photographs, many published for the first time. Numerous appendices contain orders of battle, lists of ships and key personnel.

World War II

This is a definitive account of Germany's first and last seaborne invasion, codenamed Operation Weserubung. In this work, the author takes the reader through the events which followed, from the physical response of the allies to the completed occupation by Germany's armed forces, and the withdrawal of allies.

Nautical Magazine

As with the first volume this is a meticulously researched book, with good use of Norwegian, British, French and German sources. The first hand accounts from naval vessels under heavy air attack are particularly impressive, sticking long in the mind.
