Not far from Ver beach, the battery of Mont-Fleury, comprising four Russian 122-mm guns, was still under construction in June 1944. Its casemates, which had not yet been completed, were being built according to new time-saving methods which consisted of erecting parallel walls of breezeblocks in order to obviate the need for wooden formwork. Iron rods were then placed between the walls and the space was filled in with concrete.
