Magic lantern slide circa 1900.Victorian. World war one images. An Incendiary device dropped from a Zeppelin.The first incendiary devices to be dropped during World War I fell on coastal towns in the south west of England on the night of 18-19 January 1915. The small number of German bombs, also known as firebombs, were finned containers filled with kerosene and oil and wrapped with tar-covered rope. They were dropped from Zeppelin airships. On 8 September 1915, Zeppelin L-13 dropped a large number of firebombs, but even then the results were poor and they were generally ineffective in terms of the damage inflicted. They did, however, have a considerable effect on the morale of the civilian population of the United Kingdom.[1]
