German artillery has been a subject of study for many years, but it is rare to find the original source material for such studies. These two pamphlets were issued in 1948 and include all known operational German artillery of the Second World War. In the two volumes are no fewer than 198 plates of the guns and their ammunition, and appendices, charts and tables give every detail of the weapons that was available, even to German gunners.The books are introduced with a history of the development of German artillery, and then follow a standard layout. The guns are covered in the following order: (Part 1) antitank artillery, infantry guns, recoilless guns, Field Artillery, Medium Artillery, Heavy and super-Heavy Artillery, (Part 2) light Flak, Medium Flak, Heavy Flak, Coast Defence Artillery and Railway Artillery.Among the guns covered are the 8.8cm antitank guns, 10.5 and 15 cm field guns, the 42cm Gamma Mortar, the four-barreled 'Flakvierling' (so feared by Allied ground attack pilots), 8.8cm Flak guns, the 15 and 24cm heavy Flak designs and the super-heavy 'Siegfried', 'Adolf,' 'Bruno' and the 80 cm Kanone 'E.'Many books cover this subject, but none to greater detail, nor with the wealth of illustrations that make these books a prime source for all who need information of German artillery in the Second World War.
