Department of History officers listen intently to Mr. Heintz' presentation. Thanks to Andr Heintz' reports, the Allies possessed the exact coordinates of the casemates and were able to bring accurate fire upon them. These cadets illustrate the sheer size of the Longues sur Mer casemates. Despite the accuracy of the British gunnery, not all of the artillery rounds resulted in direct damage. These pock marks illustrate the strength of the casemate's reinforced concrete, although the resulting concussion within the positions drove two of the guns' crews from their cannon.
Cadets inspect one of the damaged casemates.
Mer is a tribute to the gunnery skills of the HMS Ajax's crew.
