Engineering:List of wolfpacks of World War II
From HandWiki
Short description: none
Wolfpacks (German: U-Boot-Gruppe) were employed by Nazi Germany's Kriegsmarine during World War II against Allied and neutral shipping.
Outbreak of War
From the outbreak of war until mid-1940 there were various groups of U-boats engaged in collective patrols. With the exception of experimental Hartmann's wolfpack in 1939, the first recognised wolfpack was led by KrvKpt Günther Prien in June 1940.
Invasion of Norway & Denmark
In preparation for the impending invasion of Norway and Denmark, in early April 1940, 31 U-boats were ready for operations between England and Norway. On 6 April, the codeword "Hartmut" was transmitted and German submarines began their designated operations.
