WWI Centennial: Broodseinde and Poelcapelle

Erik Sass is covering the events of the war exactly 100 years after they happened. This is the 289th installment in the series.

October 4-9, 1917: Broodseinde and Poelcapelle

Following successful “bite and hold” attacks at the back-to-back Battles of Menin Road and Polygon Wood from September 20-October 3, 1917, the nightmarish Third Battle of Ypres (better known as Passchendaele) continued with British assaults at Broodseinde on October 4 and Poelcapelle on October 9, which continued British Second Army commander Herbert Plumer’s strategy of limited incremental gains.

Like the previous battles, the British assaults at Broodseinde and Poelcapelle were supported by huge bombardments and counter-battery artillery fire, while advancing infantry were preceded by the “creeping barrage,” a protective wall of artillery fire that forced enemy troops to take cover until the attackers were already upon them. After reaching certain pre-determined objectives, the British infantry would immediately dig in to fend off German counterattacks to recapture lost trenches.

The incremental strategy yielded another victory at Broodseinde, raising the possibility of a forced German withdrawal from western Belgium, giving up the U-boat bases on the Belgian coast – but with the change of seasons, the clock was quickly running down for further offensive operations by either side. Crucially the British had enjoyed relatively dry weather during most of this, sparing both sides immersion in a sea of mud (as in the opening phase of Third Ypres) allowing fresh troops, guns and ammunition to reach the front. But on October 2 the rains returned, plunging both sides into the cold, muddy hell of Flanders in fall.

Broodseinde

Despite the bad weather, at Broodseinde the British were initially favored by a bit of luck – or rather good intelligence work – as the attackers happened to catch the Germans unawares while preparing an attack of their own around Zonnebeke. As a result the British artillery inflicted considerable casualties among German assault troops concentrated in frontline trenches (although the Germans returned the compliment with their own preemptive bombardment of the I ANZAC Corps).

As British artillery rained destruction on German frontline and support trenches, at 6 a.m. on October 4, 1917 twelve British and ANZAC divisions went over the top and advanced in good order against enemy positions along a 14,000-yard-long stretch of front. By the late afternoon of that day the attackers had advanced around 1,000 yards and held the conquered battlefield against multiple German counterattacks, marking a decisive tactical victory by the standards of the First World War. However Plumer remained reluctant to exploit the victory by attempting a decisive breakthrough, citing over a dozen additional enemy divisions guarding rear areas.

The fighting in Flanders remained a horrible ordeal for ordinary soldiers on both sides of the conflict (above, an Australian ambulance in action at Broodseinde). Edward Lynch, an Australian private, described the aftermath of an attack in early October:

The first batches of the wounded are coming back. Walking, staggering, lurching, limping back. Men carrying smashed arms, others painfully limping on shattered legs. Laughing men and shivering men. Men walking back as if there’s nothing left to harm them and others who flinch and jump and throw themselves in shell holes at every shell burst and at each whistle of a passing bullet.

A soldier wounded in the same attack told Lynch an even more horrifying story:

‘Saw a terrible thing up there. A few of us rushed a Fritz post, but as we were right on top of it, a Fritz fired a flare gun at us and the flare went right into a man’s stomach. He was running round and round trying to tear the burning flare out of his inside and all the time we could smell his flesh burning, just like grilled meat. He gave an awful scream and fell dead, but that horrible smell of burning flesh kept on. I can smell it still.’ And he shudders and shakes at the memory of it all. ‘Did you get the Fritz?’ ‘Too true we got him. Seven or eight bayonets got him, the flamin’ mongrel!’ And the man gets up and goes away, vomiting.

Lynch himself received a “Blighty” – a wound severe enough to require treatment at a hospital in Britain – while attempting to carry a message under artillery fire. He described his near miss with an enemy artillery shell (above, Australian troops carry a wounded German):

The ground under my feet is heaving upwards. I’m surrounded by a shower of mud and blue, vicious flame. My feet are rising, rising, my head is going down, down, I’m falling, falling, through a solid cloud of roaring round… Gnawing pain shoots through me. My hip, my knee, my leg, my foot… I realise that a shell has burst under me and tossed me into the trench. I know my leg is smashed… I can feel my boot is full of blood.

Poelcapelle

Encouraged by the victory at Broodseinde, Plumer and British Expeditionary Force commander General Douglas Haig became more ambitious, planning deeper advances with an eye to a breakthrough – just as nature was turning decisively against them, with endless rain turning the heavily shelled fields into a quagmire. The rain forced the British to once again accept limited goals, but they were still determined to keep up the pressure on the Germans.

The result was a draw at the Battle of Poelcapelle on October 9, where some attacking units managed to advance but were generally forced to withdraw by German counterattacks. One British tank commander, William Watson, described the initial advance at dawn on October 9:

We went outside and stood in the rain, looking towards the line. It was still very dark, but, though the moon had left us in horror, there was a promise of dawn in the air. The bombardment died down a little, as if the guns were taking breath, though far away to the right a barrage was throbbing… Then suddenly on every side of us and above us a tremendous uproar arose; the ground shook beneath us; for a moment we felt battered and dizzy; the horizon was lit up with a sheet of flashes; gold and red rockets raced madly into the sky, and in the curious light of the distant bursting shells the run in front of us appeared and disappeared with a touch of melodrama…

By the end of the day only the Guards Division, attacking near the village which gave the battle its name, made a significant advance. All across the battlefield, the British and ANZAC attackers found it impossible to bring up artillery, ammunition, and fresh troops due to the mud, which also canceled out much of the advantage conferred by the new British weapon, the tank. Watson remembered one ill-fated sally by a tank unit, quickly swamped by mud:

It was a massacre. The tanks could not turn, even if they had wished. There was nothing for it but to go on and attempt to pass in a rain of shells the tanks which could not move, but each tank in turn slipped off into the mud. Their crews, braving the shells attached the unditching beams – fumbling in the dark with slippery spanners, while red-hot bits flew past, and they were deafened by the crashes – but nothing could be done. The officers withdrew their men from the fatal road and took cover in shell holes. It was a stormy cheerless dawn.

When Germany Planned to Airdrop Fake Money to Take Down Great Britain in World War II

Nothing looks particularly remarkable about the World War II-era printing plate at the Spy Museum in Washington, D.C. It displays the text and serial numbers you would expect to find on British banknotes from the time, but this artifact didn't come from the British government—as the video from Atlas Obscura below explains. The plate was a tool used by Nazi Germany in an attempt to delegitimize the economy of Great Britain.

When they weren't combating troops on the battlefield, Germany was devising ways to bring down other European nations using spy tactics. One of these strategies was called Operation Bernhard. By printing 130 million pounds of fake British currency and slipping it into Britain via airdrop, Germany hoped to cripple the nation's economy.

To make the banknotes, Nazis relied on forced labor from artists, bankers, and known forgers being held captive in concentration camps. Details from the authentic bills—including watermarks, serial numbers, and the type of paper used to make them—were replicated in the forged documents.

Despite the effort put into the project, the fake banknotes never made it into British circulation. The Luftwaffe, the airfleet Germany had planned to use to drop the bills over Britain, had sustained too many losses by the time the plan was ready to be set in motion. Germany may have used some of the counterfeit cash to launder money and pay off spies working for the army, but by the end of World War II, any remaining evidence of the scheme was disposed of in a lake in Austria.

Years later, those artifacts were recovered, and the Spy Museum recently added the pound notes and a forged printing plate to its collection. According the museum, the plate is the only known surviving printing plate created by Nazi Germany for Operation Bernhard.

The Quest to Find—and Save—the World's Most Famous Shipwreck

Anders Franzén lived for shipwrecks. An engineer and expert on the naval warfare of the 16th and 17th centuries, he was especially obsessed with the old Swedish men-of-war that had once menaced the Baltic Sea.

When he wasn’t busy at his day job with the Swedish Naval Administration, he’d spend hours combing through archives in search of maps and documents, hoping they might reveal the location of Sweden’s great sunken warships. And when he learned that one wreck might still be trapped, undiscovered, not far from his home in Stockholm, he was hungry to find it.

For five years, Franzén spent his spare time searching for the shipwreck. He had little luck. Trawling the waterways around Stockholm—what locals call the ström—with a grappling hook, Franzén's “booty consisted mainly of rusty iron cookers, ladies’ bicycles, Christmas trees, and dead cats,” he’d later recall.

But on August 25, 1956, Franzén's grappling iron hooked something 100 feet below. And whatever it was, it was big.

Franzén gently lowered a core sampler—a tool used by oceanographers to get soil samples from the bottom of bodies of water—and retrieved a dark and soggy chunk of black oak. The following month, Franzén's friend Per Edvin Fälting dived into the ström and see what was down there.

Fälting had to work blind. Just 30 yards below the surface, the brackish waters were pitch black. The diver ran his hands over the mysterious object and tried to get a feel for what it might be.

“I can feel something big,” Fälting said to Franzén over a diver’s telephone, “the side of a ship. Here’s one gun port and here’s another.”

There was a pause.

“There are two rows,” Fälting said. “It must be the Vasa.”

 

The Vasa was the greatest warship to never go to war. Named after the Swedish royal family—the House of Vasa—the vessel was commissioned by King Gustavus II Adolphus in 1625 and was earmarked to become his navy’s flagship. Gustavus had big dreams for the Vasa: He wanted the most lethal warship in the Baltic Sea, one that was as beautiful as it was deadly.

For three years carpenters, sailmakers, painters, woodcarvers, ropemakers, and hundreds of other artisans and craftsmen rushed to build the king’s vessel. The Vasa would be a floridly crafted masterpiece with at least 700 delicately carved sculptures, figurines, and ornaments: Angels, devils, lions, emperors, warriors, musicians, mermaids, ghastly faces, heavenly facades—all painstakingly crafted from oak, pine, and lime wood.

The boat’s exterior would be a palpable rainbow (gilded in gold leaf for extra measure). “The hundreds of sculptures clinging and clambering about the Vasa were an orgy of pink naked flesh, of steel-blue armor, of sanguine reds, poisonous greens, and marine blues,” writes Erling Matz in The Vasa Catalog. As Lars-Åke Kvarning writes in Scientific American, these ornaments had many purposes: “To encourage friends, intimidate enemies, assert claims, and impress the world with this picture of power and glory.”

The ship itself was constructed from 1000 oak trees and had three decks, including a stack of two gundecks, which would hold 64 cannons. The design was unprecedented in its size and complexity.

King Gustavus, famous for his military prowess, demanded it. At the time, he controlled “Finland, Estonia, and [Latvia], and he had just won the small part of Russia that touches the Gulf of Finland,” Kvarning writes. “By thus excluding the czar from the Baltic, he had nearly made [the Baltic] sea into a Swedish lake.” He was also juggling multiple wars and was anxious to get his hands on a new warship that would help preserve his dominance. He told the builders to make haste.

It was a foolish decision. In the early 17th century, constructing a functional ship was a matter of trial and error. (And according to Matz, there was a lot of error: In the 1620s, of the 15 naval ships Sweden lost, only two sank in the heat of battle.) There were no calculations to do or construction drawings to make. A new design was usually partially modeled on its predecessors—but the Vasa had none. The shipbuilders had to basically eyeball it. Worse yet, the Vasa’s master shipbuilder died mid-way through construction.

Baffled by the ship’s giant dimensions, the Vasa’s architects were never able to confidently determine how much ballast the vessel needed. They filled the hull with approximately 121 tons of stone but believed it needed much more. But the king, who had personally approved the ship’s dimensions, effectively forbade any alterations—and anyway, adding more ballast would have brought the lowest gundeck dangerously close to the waterline.

When the nearly completed Vasa began floating in port, the ship’s skipper, Söfring Hansson, decided to test the boat’s stability. He asked a herd of 30 men to run back and forth across the deck; after just three runs, the ship began to teeter precariously. Some of the ship’s officers wanted to inform the king that the boat was on the verge of capsizing, but Gustavus wasn’t in town. The problem was ignored.

On August 10, 1628, crowds gathered at Stockholm’s waterfront to see the Vasa off. After attending a church service, the sailors—along with many women and children, who were invited to join the maiden voyage—boarded the boat. Four of the 10 sails were unfurled and, guided by a light breeze, the vessel lurched into Stockholm's ström just before 4 p.m. The crowd cheered.

And then it began to scream.

A slight gust caused the glimmering ship to tilt to its left. The Vasa briefly righted itself, only to return to its awkward, portside lean. The captain immediately demanded that all the gunports be closed, but it was too late—water had breached the openings. As one surviving crewmember recalled, “By the time I came up from the lower deck, the water had risen so high that the staircase had come loose and it was only with great difficulty that I climbed out.”

Dozens of men, women, and children began jumping from the ship. Stockholm’s waters became peppered with helpless, flailing bodies. Sailors clambered up the ship’s sinking masts. Within minutes, the Vasa was underwater and 30 people were dead.

The world’s meanest warship had been felled by a gentle gust of wind. It had traveled barely 4000 feet.

Hearing that his prized warship was submerged, Gustavus—who was away in Prussia warring against Poland-Lithuania—demanded an inquest to find and punish the people responsible. The captain and a few shipbuilders were tossed into captivity and an investigation ensued. Some investigators claimed the cannons hadn’t been tied down and had rolled to one side, causing the boat to heel over. (Not true.) Others claimed the captain had been negligent. (He wasn’t.)

The truth was, the Vasa was just top-heavy: If anybody deserved blame, it was the man who demanded such clumsy dimensions—the king. But to implicate an infallible man who ruled by divine right was to implicate God himself. Like the Vasa, the case quickly sank from public view.

 

There is a secret swirling in Stockholm’s harbor: The water there is too brackish and deoxygenated to support the wood-munching shipworm Teredo navalis. In salty seas, this flat little bivalve will gorge itself on wooden piers, hulls, and shipwrecks—slowly destroying all signs of man’s handiwork.

But not in the Baltic. Wooden shipwrecks remain preserved in remarkable condition. (This is especially true in Stockholm, where, according to the Vasa Museum, “Centuries of raw sewage dumped into the harbor have created a dead zone at the bottom, where even bacteria cannot live.”)

Days after the Vasa sank, Sweden’s Council of the Realm sent a British man down to salvage the wreck, but the mission failed. In 1663, a Swede named Albrecht von Treileben plunged into the chilly ström under the protection of a diving bell and managed to retrieve more than 50 of the ship’s expensive bronze cannons.

After that, the Vasa’s location was forgotten for 300 years. The closest thing to a salvage mission came in 1920, when two brothers requested permission from the Swedish government to find the ship and turn the vessel’s oak into Art Deco furniture. (The request was denied.)

Franzén, on the other hand, was determined to keep the Vasa in one piece. Problem was: Nobody knew how. Nobody had ever attempted to raise a shipwreck so big or so old.

Crackpot ideas swirled. “One idea was to freeze the Vasa in an immense block of ice and let her float to the surface,” Matz writes. “The idea was then to tow the iceberg to a suitable position and let it melt in the sun, whereupon the Vasa would emerge.” There was even talk of lifting the ship by filling the empty hull with ping pong balls.

Thankfully, Franzén’s discovery generated so much interest in the Swedish media that the navy offered to supply boats and train divers, while the Neptune Salvaging Company generously offered to return the ship to the surface pro bono. Divers would use water jets to dig tunnels beneath the shipwreck. Heavy cables would be piped through these passages, creating a basket that could help lift the ship.

In 1957, the first divers plunged into the ström. Working in complete darkness, they carefully began the dangerous work of hollowing out six tunnels, ignoring the fact that tons of ballast could, at any moment, collapse onto their heads. It was a deadly workplace. “Girders, plans, and other paraphernalia meant that the air pipes and lines could easily get stuck,” Matz writes, “And they did.” (It didn’t help that, as the divers dug, they discovered at least 17 skeletons.)

After two relatively uneventful years, the tunnels were completed. The wires were piped through and strung to two pontoons (cheerfully named Oden and Frigg), which gently lifted the wreck 8 feet off the seabed. Starting in August 1959, crews slowly moved the Vasa to shallower waters and set her back down. They would repeat this motion—lift, move, lower—at least 18 times. After each successful drop, the crews would shorten the wires, ensuring the boat would inch closer to the surface with the next lift.

But before the Vasa was allowed to surface, the hull had to be made watertight. The iron bolts that once held the ship together had rusted away, and the salvage crew had to patch and fill those cavities while still submerged. (They also installed new watertight hatches on each port.) This underwater handiwork took two years.

Finally, on April 24, 1961, three giant bilge pumps began purging water from the ship’s interior and the Vasa was, once again, kissed by sunshine. Within two weeks, the Vasa was not only above the surface—it was floating.

 

For years, the Vasa was housed in a misty, cave-like warehouse. It was there, in the Wasavarvet, that the ship took a rigorous shower in preservatives.

The Vasa's wood contained approximately 800 tons of water—and it all needed to be removed. Researchers, however, couldn’t simply let the ship sit out and dry, because the waterlogged wood would shrink and split. To prevent cracking, preservationists had to spray the Vasa with a mixture of water and polyethylene glycol (25 minutes on, 20 minutes off) for 24 hours. This process, which came to involve 500 automated spray nozzles, lasted 17 years.

Slowly, water dripped from the Vasa and strings of excess polyethylene glycol trickled down, hardening to form stalactites resembling fine white candles. When the PEG-shower had finished, the humidity in the storage facility had to be gradually cranked down over the course of 10 years.

By that point, archaeologists—who had to be vaccinated against diseases such as jaundice and typhus before touching the boat—had already sifted through tons of mud and sludge in search of artifacts. By spraying down the Vasa’s decks with garden hoses, they had uncovered more than 30,000 items, including clothes, personal effects, barrels of meat, candlesticks, coins, and a piece of glassware containing a 66-proof alcohol. (“I can testify, from personal experience, that the liquor was good,” Kvarning wrote.) Divers also combed the ship’s watery gravesite to recover thousands more objects.

Of these, every wooden artifact was dunked into a vat of polyethylene glycol solution. Dozens of cast-iron cannonballs—which had rusted so much that they now weighed as much as a Styrofoam balls—were dried in hydrogen heated to more than 1900°F. Six of the Vasa’s crumbling sails, which could only be cleaned while submerged in liquid, were dried in a mixture of alcohol and the solvent xylene. (They took more than a decade to conserve.)

Meanwhile, the Vasa’s sterncastle—the elaborate perch protruding from the ship’s rear—had fallen into shambles. “[W]orkers had to identify and locate many thousands of structural components, ranging from heavy beams to tiny bits of wood—a gigantic jigsaw puzzle to be assembled without benefit of blueprints,” Kvarning writes.

Otherwise, the whole of the Vasa remained in fantastic condition. The fine ornamentations, although missing their brilliant colors, were still magnificent in their details.

Today, there’s still a lot of work to be done. In 2000, the humidity in Stockholm was so high that the presence of soggy museum visitors caused sulfur buried in the ship’s wood to produce corrosive acids. The ship is also shapeshifting. To monitor wood deformation, geodetic measuring devices are being used to map slight changes in the ship’s shape (which is currently settling 1 millimeter every year [PDF]). To combat a potential breakdown, carpenters have built a replica of the Vasa’s hull, which is undergoing a battery of stress tests that will hopefully teach preservationists how to improve the ship’s stability.

That hard work, however, has already paid off. Today, the Vasa Museum is the most popular cultural institution in all of Scandinavia. Home to the world’s only preserved 17th-century ship, the place is more than a vital time capsule—it’s an homage to an ongoing rescue mission more than 300 years in the making.
