He instituted the 4-rotor M4 Enigma machine in February 1942 only as an additional insurance. Donitz never realized that the codes had been broken (nor did anyone else until 1973/74, when Gustave Bertrand and F. W. Winterbotham published their accounts of the Enigma code breakers). The M4 did however result in a 10 month blind period in the Atlantic for the allies, which coincides almost exactly with "the second happy times". Fortunately Donitz - again - didn't succeed in putting 2 + 2 together.
