After the watergate bridge was destroyed, two more accidents nearly prevented them from getting out

With the release of the movie Watergate Bridge, December 7, 1950, an ordinary day, became a day to remember the fallen.On this very day, the volunteers paid a great price, for the third time blew up the Watergate Bridge!Unfortunately, the Americans, with their engineering prowess, were able to build a new bridge in a short period of time, allowing them to escape the encirclement of the volunteers.It is well known that the U.S. military restored the Watergate Bridge with steel components after it was destroyed by an explosion.But it was also a time of accidents.Their retreat was not as smooth as expected.The bridge was broken, in fact, as the U.S. military had expected.So in addition to placing a lot of building materials near the bridge, they also shipped in a lot of standard M2 bridge components in the morning, ready to go.When it comes to the M2 bridge component, it is necessary to mention its design prototype.In World War II, the British designed and built a prefabricated steel bridge.In the use of engineers, as long as several standard parts are combined together, they can form a simple temporary steel bridge with a certain load capacity.Such steel Bridges played an important role in the European battlefield.The British patented the design to protect intellectual property rights.In 1941, the Americans bought the patents from the British and redesigned the components through their own more powerful industrial capabilities.Since then, the Army Corps of Engineers’ warehouses have been stacked with components of all sizes.This is where the M2 bridge component comes in.In fact, this bridge component is not a sophisticated technology product.It was just one of the standard engineering components of the US military, and now any Chinese engineering facility can produce it.At the time, few countries had such engineering capabilities.After the Start of the Korean War, the U.S. military supplies to South Korea included a large number of M2 bridge components.These components also played an important role in the early days of the war.Later, as the U.S. advanced north of the 38th Parallel, the bridge components were transported to the Yeonpo military airfield, ready to be deployed to frontline troops.After the Watergate Bridge was destroyed by an explosion, Lt. Col. John Partridge, commander of the U.S. Army corps of Engineers, evaluated the damage.He found that the fracture had reached 19 feet, or about six meters, across.The U.S. military’s current repair equipment is beyond measure.So he’s reporting to 1st Marine Commander Oliver.Smith immediately began deploying M2 bridge components for airdrops.In Partridge’s view, it would be more appropriate to ship large 24-foot-long components directly.In this way, assembly time can be saved.But the 24-foot assembly is so heavy that it would be difficult to drop it.Therefore, Yeonpo Airport decided to conduct an airdrop test first.They attached six conventional G-1 parachutes to the 24-foot assembly.Five parachutes failed to open before landing!The 24-foot steel component slammed into the ground, creating a crater 1.8 meters deep!The experiment failed, but the time for help at the front was too short for a second experiment.It was decided to drop eight 12-inch components and use the largest 48-inch diameter parachute on the drop platform.Soon, the 314th Airlift Wing, which was in charge of transportation, was flying components over the battlefield.For fear of hitting soldiers on the ground, they chose to drop closer to the edge of the volunteer line.As a result, one component was damaged when a parachute failed and fell into a valley, and one component was taken by volunteers.The remaining six were dropped into their designated positions for the Americans.The U.S. army’s bridge operation was thus carried out.Accident two: crushed plywood The US Army Corps of Engineers, with the help of a large piece of equipment, held the assembly together with a giant screw 1.3 metres long, leaving the rest of it resting on the break.In fact, it only takes 4 M2 bridge components to build a bridge.Now they have six. It’s a safe bet.Can not expect, the appearance of a tractor, almost let all the cars stay in place.According to the engineering requirements, after the M2 bridge assembly is set up, a layer of high density plywood with a load capacity of 20 tons is laid on it.Because to pass a tank, the steel structure must be set up according to the width of the tank’s tracks, which are larger than the width of a car’s tires.So to walk on it, you have to use plywood.This would have been fine, since cars weigh less than tanks.But a nerve knife driver, actually drove a tractor full of earth and stone onto the steel bridge!A tractor and heavy earthwork added up to more than 20 tons.As a result, the plywood was crushed and the tractor was stuck on the bridge!The americans were once again in a desperate situation, as the steel bridge in front of them was blocked by their tractors as the volunteers approached.At that point, a Navy Tech sergeant named Wilfred walked up, grabbed the errant driver off and got behind the wheel of the tractor.The man, an old and skilful driver, backed the tractor back over the bridge and cleared the road in a few seconds.The road is now open, but the problem is still unresolved.The plywood has been crushed by the tractor and cannot bear its design weight.There was no problem with the tank due to its steel beam.However, the 1st Marine Division still has as many as 1,500 vehicles.Cars can’t get through without plywood!1st Marine, still locked down near the Watergate Bridge.At the critical moment, Battalion Commander Partridge of the engineering corps once again played his part.He observed that by placing the steel beam in a fixed position, the tank could pass while the epitaxy of the car’s tires rested on the beam!It’s only half an inch, but it’s enough to get them through.However, this requires very skilled driving skills, not veteran drivers can not do the job.However, there were many experienced drivers in the American convoy, and soon people began to try.In front of the convoy, there are two guides with torches to guide.And all the American drivers turned off their headlights and drove through the steel beams in a panic.They’re one mistake away from falling off a cliff and ending up in pieces.During the whole process, except for the driver, all the other personnel got out of the car and walked.This is partly to lose weight, but also because it is so dangerous that no one will dare to follow the driver.Henry, American war correspondent.Smith later recalled, “I didn’t want to escape in any vehicle through this hellish road, down a mountain that would never be flat.”Under such driving conditions, the Americans managed to survive and maintain a speed of two miles per hour.Within two hours, more than a thousand cars crossed the steel bridge and escaped.”It was the creepiest thing I’ve ever experienced in my life,” Partridge recalled afterwards.
