One major propaganda avenue was the use of atrocity stories. These aimed to mobilise hatred of the German enemy by spreading details of their atrocities, real or alleged, and was used extensively by Britain, reaching a peak in 1915, with much of the atrocities related to Germany's invasion of Belgium. One of the first significant publications to be produced by the Bureau was the "Report on Alleged German Outrages", in early 1915. This pamphlet documented atrocities both actual and alleged committed by the German army against Belgian civilians. Other atrocity stories included the fate of the nurse Edith Cavell and the Sinking of the RMS Lusitania. These had a significant impact both in Britain and in America, making front-page headlines in major newspapers.
