Answer 1

Czech Hedgehogs. This is coming from Time's "D-Day: 24 Hours That Saved the World" tribute they put out for the 60th anniversary of the Invasion of Normandy. In the chapter 0200-0300: The Germans on page 34 it's stated Rommel put together numerous traps and obstacles which he called "my inventions." These included the beach obstruction called Czech hedgehogs which were three six foot long railroad rails that had been welded together in that X pattern

Answer 2

" the most commonly used obstacle was the hedgehog or tetrahedron "

"Tschechenigel (Czech hedgehog) "

But that was only one of many different beach obstacles including "Belgian gates" "log ramps" and "Rommel's asparagus"

the latter being a single angled pole topped with a mine.

Answer 3

Hedgehogs
