Wolfpacks (German:U-Boot-Gruppe) were employed byNazi Germany'sKriegsmarine duringWorld War II against Allied and neutral shipping. They were also used later in thePacific War by theUnited States against Japanese shipping.
From the outbreak of war until mid-1940 there were various groups of U-boats engaged in collective patrols. With the exception of experimentalHartmann's wolfpack in 1939, the first recognised wolfpack was led byKrvKptGünther Prien in June 1940.
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.
