The Bocage Hell: Roman Hedgerows That Stopped the Allies

The Normandy bocage — thick hedgerows of earth and tangled bramble that separated centuries-old farm fields — created conditions worse than any Allied planner expected. The hedgerows were over 2,000 years old, some originally planted by the Romans and reinforced over millennia. Each hedgerow was effectively a natural defensive wall with firing positions carved into it by the Germans. Tanks couldn't climb them (they simply flipped over the top), and infantry couldn't safely cross the sunken lanes between fields. American troops advanced mere yards per day in some sectors. A Rhode Island mechanic and National Guard sergeant named Curtis G. Culin Jr. improvised a solution: he welded steel teeth (salvaged from destroyed German beach obstacles) onto the noses of Sherman tanks, creating 'Rhino tanks' that could simply plow through the hedgerows. Within weeks, 60% of American tanks in Normandy were equipped with the modification. The hedgerow fighting earned Normandy the nickname 'Hell of the Bocage' among American troops.
