In his book “A Requiem for Caravan PQ-17,” Valentin Pikuly tells of the destruction of an allied convoy in the northern latitudes during the Second World War. PQ-17 was placed under an unspoken ban right away. In the atmosphere of wartime secrecy, the secret of the convoy’s loss was managed to be preserved. The truth was that ordinary British sailors somehow suspected that one of the Arctic convoys had met with disaster—but what exactly happened, they would never learn. Meanwhile, in sailors’ letters sent home from German concentration camps, wartime editorial cuts ruthlessly removed lines where people accused their command of sending them to the slaughter—and of deliberately putting them under the executioner’s axe.
