Book excerpt: The Paris Gun, first published in 1930, is a detailed account of the design, construction, and operation of the several German long-range cannons used to bombard Paris in 1918. While not accurate, the guns were used to instill terror in the civilian population and over 300 of the massive shells were fired on the city between March 23 and August 9, 1918. After the war, author Henry Miller, a U.S. Army ordnance officer, interviewed German artillery officers who were directly involved in the project, providing a unique, first-hand look at these weapons. Included are 38 pages of illustrations and maps.
