Early in 1944, with an Allied invasion of Nazi-occupied Europe becoming ever more likely, [[Field Marshal]] [[Erwin Rommel]] was assigned to improve the wall's defences.{{sfn|Darman|2012|pp=8–9}}{{sfn|Overlord|2009}} Believing the existing coastal fortifications to be entirely inadequate, he immediately began strengthening them.{{sfn|Overlord|2009}} Rommel's main concern was Allied air power. He had seen it first-hand when fighting the British and Americans in [[North African Campaign|North Africa]], and it had left a profound impression on him.{{sfn|Overlord|2009}} He feared that any German counterattack would be broken up by Allied aircraft long before it could make a difference.{{sfn|Overlord|2009}} Under his direction, hundreds of [[reinforced concrete]] [[Pillbox (military)|pillboxes]] were built on the beaches, or sometimes slightly inland, to house machine guns, [[antitank guns]], and light and heavy artillery. [[Land mine]]s and antitank obstacles were planted on the beaches, and underwater obstacles and [[naval mine]]s were placed in waters just offshore.{{sfn|Assault Plan}} Little known was that touch sensitive mines were placed atop the beach obstacles.  The intent was to destroy the Allied [[landing craft]] before they could unload on the beaches.{{sfn|Assault Plan}}
