白狼行动Just after the First World War Fred Roberts goes for a job as a newspaper journalist and tells the sub-editor how, in the trenches in 1916, he discovered a printing press in working order. Helped by ex-printer Sergeant Harris and with his friend Jack Pearson as his assistant, he sets up the Wipers Times - the name coming from the soldiers' pronunciation of the town Ypres. Despite disapproval from officious Colonel Howfield but with backing from sympathetic General Mitford they produce twenty-three issues of a satirical magazine - its articles represented on screen in black and white - which boosts morale and even gets mentioned in the Tatler. The press is destroyed by a German shell but another is found and the paper's title changed to fit in with wherever the regiment is deployed.
