Ian Castle tells the story of Germany's air offensive against Britain in World War I (1914-1918), in which, from May 1915 until October 1917, zeppelins dropped thousands of tons of bombs on London. Initially the city was woefully unprotected but an integrated air defense system was progressively developed in response to the early months' destruction and casualties. Over a year was to pass before the first zeppelin was downed over British soil by the Royal Flying Corps but successes then steadily mounted as observation and communication networks improved and new tactics were learned. In his revealing account of a terrifying campaign which was to be repeated only decades later in the Luftwaffe's Blitz, the author describes the birth of a new arena of warfare, "the home front."
