The single most massive military maneuvers in history were represented the Normandy Invasions. On 6th June 1944, D-Day, the invasion was the biggest amphibious assault of all time. It involved what amounted to the collective might of a large percentage of the nations in the world of industrialization. There were so many images of invasion, and one of the best yet famous images of invasion was that of a French beach covered in oppressive-looking metal crosses. It turns out, and those crosses were just a small part of an expansive network of sophisticated defenses the Allies managed to somehow circumvent in mere hours.
Dubbed and constructed under Adolf Hitler’s direct orders in his directive 40, the formidable defenses stretched 2000 miles of the European coast. With intent to retaliate an Allied invasion, the Atlantic Wall consisted of endless batteries of guns, an estimated five million mines, and many thousands of soldiers who occupied heavily fortified bunkers and fortresses along its length.
The three-tier system of fortifications was the phrase given to the wall where the most valuable and vulnerable locations were the most heavily fortified. At the same time, positions of lesser importance became known as “resistance points.” As they all were in the rush of creating defenses, gun batteries were haphazardly thrown together, which consisted of whatever Nazis could get on their hands. Everything from massive cannons to heavy machine guns from captured French warships was utilized in the construction of fortresses and bunkers.
Story of Czech hedgehogs
The largest of these guns represented Atlantic Wall defense’s first line, and the Germans spent countless hours practicing shelling. After this defensive implantation, known as the Belgian gate. Belgian gate was large, heavy fences attached to steel roller, which could be even positioned in the shallows.
The Soviets made the extensive use of Czech hedgehogs, often using the concrete to cement them in several regions of cities and along bridges to halt German armored divisions in their tracks. You can also imagine that just one of these hedgehogs in narrow streets proved to be an effective barrier that also left the enemy trying to get rid of it open to weapon fire.
Some of the Czech hedgehogs were constructed to specific factory specifications, which stipulated exact measurements and materials. Czech hedgehogs were also made of scavenged materials. The materials behind the construction of Czech hedgehogs were anything sturdy enough to survive around 500 tonnes of force.
The hedgehogs, along with other fortifications, proved to be a formidable, but not impassable obstacle for the Allies. Thanks to a massive, concreted bombardment effort from the naval and air-forces of the Allies, commando strikes, and the bravery of the hundreds of thousands of troops who stormed the beaches.
