Tank Hack Ensured Farmland Didn't Thwart the Invasion of Europe 143

szczys writes: Ingenuity reigns supreme when trying to overcome obstacles standing in your way. So was the case during the Allied invasion of Europe during WWII. Land features in the Normandy bocage region were especially difficult for tanks to navigate. The obstacles were earthen dikes topped with mature trees originally put in place to contain livestock. The solution was to reuse materials from the Axis' own anti-tank measures to build a tank attachment to cut through the obstacles. The Allies were able to take the Axis by surprise as it was assumed the armored divisions wouldn't be able to break through this area.

          Well maybe a decade or so ago when they showed documentaries about the Normandy invasion, more recent years probably the Military Channel. Unless we're talking about a wrestler hitting someone with a cutup i-beam or something.

          ... "Band Of Brothers" ...

          Don't think so. Except perhaps a tank so equipped may have been a background prop or something. Don't recall any explicit demonstration or discussion of the device.

              I am way too lazy for this but the person who created the original idea, sort of, with all the modified tanks (I'm lazy and didn't go find his name, etc) has his own documentary. They called the tanks _____'s Funnies, as I recall. They made quite a few versions for specific goals, based on the Sherman I think, and one of the neater ones had a tarp that it drove over that was wound under it. Why? So that the tank wouldn't sink in the soft sand.

                Hobart's Funnies were based around all kinds of tanks, primarily Churchills and Shermans, but there were also Valentines, LVT4's, Cromwells etc.

                As for the Bobbin, it was actually a device carried by the Churchill AVRE(together with the Crocodile and the ARK the most famous Funnies), and it laid the canvas road not only for itself but also the vehicles coming up behind it. Other devices the AVRE could carry was the Fascine, which was a bundle you dropped into ditches and trenches, so you could drive over them, and the mine plough, which could also do the same job as the hedgerow plough on the Shermans.

                  Awesome! I knew that someone would know exactly what I was speaking about and would remember more of it than I do. There's, as I mentioned, an excellent documentary about him and the varieties that he created. I'd thought they were mostly built on the Shermans and a few models based on the Churchills. I had no knowledge of the others being utilized, thanks for the information.

                  He designed another one that was kind of interesting. It dropped sticks into and on to stuff. I thought that one was rather creative.

                  • The thing made of sticks (it's a bundle of bundles of fairly big logs) is called a fascine. The clever thing is that it's not bound too tightly so it automagically conforms to spread the load and fill the hole.

                    It was carried on a special tipper mount on the front of the tank.

                    • P.S. The difference is that the funnies were specifically designed in advance, largely based on the failure[1] of the 1943 Dieppe raid, whereas the hedge cutter was improvised on the spot.

              The HBO miniseries "Band of Brothers" and "The Pacific" are pretty good from a historical perspective. Very respectable adaptations of books written by a well regarded historian who did great research or written by veterans themselves. Read them all plus Winters' book. Sledge's "With The Old Breed" was probably the standout for me among the veteran's books. Very well written, of course he had been a university professor for decades by the time he authored his book.

              HBO's "The Tuskegee Airman" seemed a respectable attempt at telling that story. It may have been a little more fictionalized given its time constraints, more composite characters and coalescing of events for example, but it certainly seemed far better than the Lucas "Red Tails" mess from a historical perspective. "Red Tails" went from beyond dramatic license and into cartoonishness IMO.

        Not "engineering" in the sense that engineers at a company came up with the device. The phrase "hack" is entirely appropriate. This modification came from a Sergeant at Normandy who thought he could cut up some of the i-beam based beach obstacles and make "teeth" for the tanks. So the solution came from the blacksmith/welder types, an actual Army MOS, improvising something on the spot not the engineers designing something to meet a requirement.

          Yep, it's an awesome improvised hack. I'm a WW2 history aficionado, so of course I'd heard about this before.

          For all the unbelievably thorough preparations made for the allied invasion, historians and laypersons alike have always found it fascinating or puzzling that apparently no thought was given to the potential tactical disadvantages the bocage (hedgerows) would have on the allied advance, or how the allies might try to cope with it. It took a lone Sergeant in the Army tank corps to come up with a reasonable solution to the problem. I suppose nothing tends to motivate you like facing a potentially lethal situation.

          I'd rank it up there with the CO2 scrubber hack on the Apollo 13 mission.

          • The ability of tanks to knock down trees and crash through brush in North America and England probably gave them a false sense of security. They just did not fully understand the density of the bocage. Its not unlike layers of specially weaved fabrics in old "bullet proof" vests, spreading the energy of impact over a larger surface area and preventing penetration.
            • Yep, that sounds plausible... If I had to guess, I'd also say that the planners were probably so fixated on the horrifically complex logistics of landing troops and followup supplies on the beach that everything else seemed unimportant by comparison.

              We know that the allies had ridiculously optimistic timetables as well, so perhaps overconfidence played a role as well. For instance, UK troops had originally planned to take the town of Caen [wikipedia.org] as part of their D-Day objectives. Instead, thanks to German armor

            That's because they weren't supposed to go through the hedgerow terrain. When Montgomery failed to take Caan on the first or second day, the entire operation had to be modified, and the breakout was changed to the boccaged west instead of the east, which was excellent flat tank terrain.

The US military, being far more conservative, dismissed the concept of Hobart's Funnies as frivolous and doomed to failure, and also counter to their doctrine, in that it'd make tanks take the lead and end up in combat with enemy tanks, which US doctrine specifically and emphatically discouraged: Tanks were for infantry support and breakthrough, fighting it o

            • The US rejected Hobart's funnies because most of them were based on the Churchill tank. Nothing more. Nothing less. The US had standardized around the Sherman in order to simplified the maintenance costs by making sure every chassis was using the same parts. Bringing in the funnies would have expanded the logistic requirement.

      The main reason the allies were able to take the Nazi's by surprise in Normandy is because they had managed to completely convince Hitler that the invasion would be led by Patton at the pas de Calais.

      On the morning of the Normandy landings, they woke Hitler and told him the allies had landed in Normandy. He dismissed this as a ruse, said the invasion would be at Calais and refused to release an armoured division to Normandy. Thanks to this, the landings were considerably less bloody than expected.

    The hedgerow taming attachment to the tanks are quite well known to most WW-II buffs. But there were many thousands of such local mods.

    One of the best ones I have heard about is the hacking of the Dutch telephone system by the insiders. They had special "area codes" that bypassed main trunk exchanges but allowed the resistance fighters to communicate using the regular telephone system. If Gen Montgomery knew about it or had used it, his Operation Market Garden (movie: A Bridge Too Far) might have gone differently, they last bridge group might have learned the the German General Model and his panzer divisions were being held in that area as reserve and for refitting and they were in a position to cut off the lines of communication.

      Picture a german bazookaman behind the hedge ready to blow a hole in your soft underbelly.

    • by nytes ( 231372 )

      As I understand it, the hedgerow growth was so thick (more like trees, actually) that the tank couldn't crush it readily. Instead, the front end of the tank would lift high into the air before bearing its full weight on the hedge, giving exposure to the thinnest part of the armor. Even if the tank made it over without taking a shell to its belly, the hedge probably sprang back up behind it, cutting off any infantry support it might have had following it.

      Lets look at how a hedgerow is created. In medieval Europe fields were sectioned off into small areas with hedges between them. Every year due to frost action rocks are driven to the surface by frost action. Every year farmers go through their fields and throw these rocks into the hedges. Over the decades and centuries these hedgerows become very solid. In effect they were stone walls with hedges on top and there were a lot of them on Normandy. here [flickr.com] is a better explanation of why hedgerows were a problem.

In some areas the overgrowth from the bocage is such that there's a tunnel that you'd drive/walk through and it's made out of trees. We see some areas like this up in Maine in the more rural areas on old dirt roads that have fallen into disuse. Your grandmother probably has a similar picture of the latter taken during foliage season and hanging

            Huh. Yeah, I would certainly not want to be there in a combat situation. Must be a bitch when it rains too.

              I'm an automobile aficionado and, because of this, I own far more cars than is healthy. Each one of them is owned for, generally, very specific reasons and each of them is utilized to for enjoyment in those particular areas - some are also utilitarian such as an RV and a couple of pick up trucks. One of my goals is to put such vehicles through their paces. I get a great deal of enjoyment from pushing them beyond their design limits. My enjoyment means that, most weekends, I have a local garage that sends so

    • There are some good comments in the link, one of them has a video of a tank equipped with the device in use

    The D-Day plan included the capture of Caen on D-Day itself. If you ever visit Normandy, it is obvious that the river valley around Caen is the only good way out. The German's realized this too, and sent every possible unit there to keep the British from seizing the exit from the beaches. Battle after battle erupted in front of Caen to keep the Allies in. The Allied plan took the bocage hedgerows into account. They were protection from German counter-attack while the American Army took the port of Cherbourg and the Cotentin peninsula to serve as the staging area for incoming units to prepare for the breakout. With the main German force facing the British at Caen, the only other way to break out from the beachhead was through the bocage. This had never been part of the Allied plan, so it took some improvisation to develop tactics to break out.

    Every War Has Hacking, if you want to survive. You learn from the moment you start fighting.

    In France, there were hedgerows, and you needed a way to deal with them.

    In Korea, there were lots of jeeps but limited alcohol, so you figured out how to make a still from the parts of a jeep.

    In Iraq, the army learned it needed MRAPs right away and that the military procurement system was so terrible it would never get them, so SECDEF basically overrode the whole damn procurement apparatus.

    From the article:

    When demonstrated for General Omar Bradley, he was impressed enough to order them built in quantity for the tanks. Eventually the prototype became an engineered product (dubbed the “Culin Rhino Device”) that was fitted to many tanks before being shipped over from England.

    I wonder how long it took, from the demo for Gen. Bradley, until the device was fitted on tanks sent over from England. Hopefully not too long. Imagine the tanks being made in the US today. How long would it take before they were outfitted with the "tusks"? Senator #1: "I demand that the tusks be made in my state." Senator #2: "No - make them in my state, or I'll vote against them being made at all!"

    In related news, U.S. Air Force instructs airmen on exactly how to praise the F-35 [fortune.com]. The Air Force should reject the F-35 for its many flaws, and demand their money back. Sigh. Some things really were better back in the past.

      During the Iraq War the humvee's were vulnerable to roadside bombs. The soldiers added "hillbilly armor" [wikipedia.org] by welding steel plates to the sides. My neighbor's son made a few runs down to Kuwait to pick up loads of steel for that purpose. Your view of the world doesn't match reality.

  • I think it was the hedge rows and not trees that were so difficult for tanks. Tanks can deal with trees rather easily but the hedge rows would snarl the tracks and everything else on a tank. If you think about it trees will make a poor cattle fence as cows can simply walk between the trees as there has to be a gap for trees to grow. Generally trees do not grow well, shoulder to shoulder. A hedge row can make a great fence. As I recall it was a farm boy from a rural state that showed the staff how to a
  • From the article:

    Without Sgt. Culin’s battlefield hack, and his inspiration by a hillbilly named Roberts whom history otherwise forgets, the invasion of Europe might have taken a very different course.

    Others say, not so much. [wikipedia.org]

    Military historian Steven Zaloga claims that the devices "were not as widely used as the legend would suggest", nor were they as effective as is often believed.[13] But Max Hastings and Chester Wilmot credit the invention with restoring battlefield maneuverability to the Allied force.[6][19] Martin Blumenson states that while the device restored mobility in hedgerow country, it "was of little tactical value in the breakout, except possibly as a morale factor to the troops, since the tanks advanced on the roads, not cross-country."[20]
