List_of_wolfpacks_of_World_War_II
Wolfpacks (German: U-Boot-Gruppe) were employed by Nazi Germany's Kriegsmarine during World War II against Allied and neutral shipping.
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 and 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.
