British intelligence aware of Nazi Holocaust from 1941, says report

According to a US government report quoted by the "New York Times", British intelligence intercepted coded Nazi messages from 1941 onwards that could have revealed the extent of Germany's plans to exterminate Jews. The messages apparently provided clues which could have save millions of lives had they been acted upon, but the British largely failed to understand the intelligence, which often lacked context. The report  "Eavesdropping on Hell" was written by Robert Hanyok, a historian with the US National Security Agency. "The analysis suggests that the allies largely failed to understand the information they had, information that might not have given advance warning of the Holocaust, but could have prompted a military response that could have interrupted the deportations or mass exterminations or, at least a propaganda campaign against Nazi atrocities." The Allied intelligence depicted accounts of massacres, deportations and statistics on killings at concentration camps, but the pieces of information often lacked the necessary context, according to the report.
