Summary

Summary

An attack by a British destroyer on a German U-boat in the Eastern Mediterranean in October 1942 altered the course of the entire war. The capture of secret German Enigma coding material from U-559, at the cost of the lives of two of HMS Petard's crew, enabled Bletchley Park's codebreakers to crack a new Enigma system introduced to cover a maximum U-boat offensive. After ten critical months with no U-boat signals intelligence available, this was the crucial factor in defeating Hitler's Atlantic U-boat wolf packs before they could starve Britain into defeat in the winter of 1942-3.
