The Battle of the Bulge, a significant event during World War II, took place in the densely forested Ardennes region between Belgium and Luxembourg. It was the last major German offensive on the Western Front. For almost 80 years, the secrets of this battle have remained hidden beneath the trees. However, researchers have recently utilized drone-mounted LiDAR technology to uncover these hidden secrets. LiDAR emits pulses of light to create 3D models and maps, allowing researchers to see through the thick forest canopy.
This study, conducted by experts at Ghent University in Belgium, focuses on a 4.4-hectare area between St Vith and Schönberg. Previous research conducted in 2008 had only identified 11 features in this area. However, utilizing LiDAR, the researchers have discovered nearly 1,000 features within the landscape. These features include dugouts, bomb craters, and artillery emplacements. The team was also able to differentiate between different types of features based on their shape and depth.
By visiting these newly identified features on the ground, the researchers were able to tie them to specific events of the battle. For example, the discovery of German objects at American artillery emplacements suggests that German forces made use of abandoned American fortifications.
This study provides a better understanding of the extent and significance of the Battle of the Bulge. Furthermore, this technique of utilizing LiDAR technology can be applied to other wooded areas in Europe, contributing to our understanding of multiple WWII battlefields. The recognition and designation of these war traces as heritage sites could help ensure their long-term protection.
