What Can Be Learned from Shell Fragments? Examples from World War II Battlefields in the Maritime Alps

Shells were the most deadly weapon used during the conflicts of the twentieth century involving industrialized nations. Astronomical numbers of them were produced and fired, making shell fragments the most common artefact to be found on modern battlefields. An understanding of shell fragments can therefore be useful to the battlefield archaeologist. This paper discusses the three main components of artillery shells and mortar shells: the body, the fuse and the rotating band for artillery shells or the tail-fin assembly for mortars. Analysing the fragments of these components can provide important information, including nationalities, types, and calibres of shells used in an area. Body fragments are the least useful, but can prove helpful if they are large, or contain markings, threads, or fragments of band seat. Rotating band fragments are extremely characteristic as well as easy to find, and a single fragment is usually sufficient to determine the exact type of shell it came from. Tail-fin assemblies are also specific of the mortar shell they were used on. Fuses are typically covered with highly informative markings such as dates of manufacture, lot numbers, or factory codes. Because the information derived from the analysis of various shell fragments is a cheap and relatively easy way to help maximize the understanding of a battlefield that is being investigated, any archaeologist working on a modern battlefield should familiarize themselves with this topic.
