Archaeologist Ben Robinson flies over the Thames to uncover new discoveries about World War 1. A whole network of trenches has been discovered on The Hoo peninsula. Invisible from the ground, they were recently found from aerial images of the area next to the former Chattenden Barracks. The trenches were used for experimentation and training of soldiers and can be directly linked to trenches used in Belgium in WW1. The trenches are just one feature revealed by the first full aerial survey of the area by English Heritage. Much of the history of this area is being recorded from the air before its destroyed by coastal erosion and development. Show less
