The Sinking of the Blucher
Haarr, Geirr H / Melien, Tor
This book is a methodical, unbiased compilation of primary sources and archival material. It details the sequence of events leading to the sinking of the Blücher, the flagship of the force that was to seize Oslo, from setting sail for Norway, to evading British submarines in the Skagerrak, and finally sinking to the bottom of the Drøbak Narrows after being struck by Oscarsborg fortress gunfire and torpedoes.
