APRIL 9-MAY 1, 1918: “WITH OUR BACKS TO THE WALL”

The second mighty blow of the final German offensive on the Western Front in spring 1918, Operation Georgette, was German chief strategist Erich Ludendorff’s attempt to force the British Expeditionary Force into the sea with fresh troops arriving from the victorious eastern front. Known to the British as the Fourth Battle of Ypres or the Lys Offensive after its location along the Lys River, from April 9 to May 1, 1918 Georgette pitted a total of 35 divisions from the German Fourth and Sixth Armies against a defensive force initially totaling just 12 divisions from the British First and Second Armies around the village of Armentières, south of Ypres.

Once again, German gunners used the new mathematical registering technique perfected by Colonel Georg Bruchmüller, targeting artillery without the need for range-finding and test firing, helping to preserve the crucial element of surprise. The bombardment would be virtually unprecedented, with the German Sixth Army’s artillery firing a total 1.4 million shells on the first day alone, averaging 16 per second. As in Operation Michael, the German infantry advance would be spearheaded by thousands of storm troopers in special battalions armed with light machine guns, mortars, flamethrowers, and sometimes field guns.

Georgette debuted at 4:15 a.m. on April 9, 1918, with 2210 German guns opening fire along a 25-mile stretch of front, including five miles held by the demoralized, undermanned Portuguese Expeditionary Corps. Following an Earth-shattering bombardment pounding the Allied artillery and saturating British and Portuguese trenches with a combination of high explosives, poison gas, and tear gas shells, the German guns laid down a creeping barrage with shrapnel and high explosives to protect the advancing stormtroopers and regular infantry (top, British soldiers wounded by poison gas). John Tucker, a 20-year-old British infantryman, described being wounded in the German bombardment on April 9:

"Suddenly a barrage of shells came screaming over and dropping a short distance beyond us, several bursting quite close. We moved to the trench side, bunching to get down at a convenient place. It is possible after a little experience to tell from the scream of an oncoming shell to know if it is going to fall within a few yards or to pass over one’s head. I heard one coming that I knew was going to land on us. I did not hear the final scream of the shell, nor what must have been the awful noise of its explosion. I felt a terrific blow on the left side of my back, like the kick of a horse, felt my knees buckle under me, and lost consciousness. I have no idea for how long I was in this state, but came to with an awful pain in my back and stomach, and hearing a lot of moaning noises. Realizing that some of the moaning was coming from me, I shut up, but there was much of it still going on around me … Now convinced that I was dying I had a peculiar hallucination of a light opening between clouds in the sky and voices singing and calling me in. I was not at all scared during all this, but apart from the pain felt quite calm. After a while I began to think how much I would like to see my mother, father, and sister just once again before I died, and then, of all things, a longing to walk once more at night along by Finsbury Park, and became determined that I would last out to do these things."

Chief strategic Erich Ludendorff had chosen his target with typical precision: the main blow fell squarely on the weak, demoralized Portuguese force in the middle of the line, causing the Portuguese divisions to simply disintegrate. British war correspondent Philip Gibbs described the overwhelming destructive power of the German shelling:

"It was a tragedy for the Portuguese that the heaviest bombardment, in a storm of gunfire as atrocious in its fury as anything of the kind since March 21, was directed against the center which they held. It was annihilating to their outposts and mashed their front-line defenses, which were stoutly held. It beat backwards and forwards in waves of high explosives."

Captain R.C.G. Dartford, a British liaison officer attached to the Portuguese 2nd Division, described the extraordinary speed of the German advance over the Portuguese positions, largely abandoned in panic, followed by the swift collapse of the Portuguese Expeditionary Corps on the morning of April 9:

"I think the Boche must have taken our front line about 8:30 and the B line 8:45 and was up to batt H.Q. by 9:15 or so. One message from X. de Costa (CO 29th Batt.) said he no longer had any command and that it was now a question of individuals fighting out. He was killed, we learnt after … Stragglers passed thro’ Laventie but most of them chose the open fields and wisely. We got hold of one and he said, “Everyone was running from the B line, so I did too,” though he hadn’t seen the Boche. We put two sgts to try and collect stragglers but they soon came back saying it was impossible to stop them and that officers were getting away too."

As during the first days of Operation Michael, the German Sixth Army’s steamroller of artillery and men advanced inexorably at first, taking over three miles by around noon on April 9, reaching one of their first day objectives, the River Lys, by mid-afternoon, and penetrating up to six miles by nightfall. Once again, however, the Germans failed to achieve all their ambitious first-day goals, especially on the left wing of the attack, where they faced a fierce defense by the British 55th Division around the villages of Givenchy and Festubert. And as in Michael, this delay gave the Allies critical breathing room, a few precious days in which to assess the direction of the latest German thrust and rush hastily summoned reinforcements to the battlefield, including ANZAC and South African troops.

The following day Ludendorff sent the German Fourth Army to the north, rumbling into action to support the Sixth Army’s attack, widening the scope of the offensive to include the whole Ypres sector. By noon the Fourth Army had captured the strategic area of Messines—first conquered by the British in summer 1917, and briefly recaptured by an Australian brigade on April 10 before being lost again. The combined advance by the Fourth and Sixth Armies threatened British control of the Channel ports, critical supply bases for the British Expeditionary Force—a disastrous scenario.

The ensuing struggle was undoubtedly grim for the Allies, as the Germans came alarmingly close to breaking through the British line in Flanders, and the Allies’ new supreme commander, Ferdinand Foch, claimed he was unable to send help. On April 11, as 31 German divisions battered 13 Allied divisions, British GHQ staff officer Brigadier-General John Charteris confided gloomily in his diary:

“It looks as if we should have to fight out this battle alone, and we have no reserves. It will decide the war. God grant the decision is not against us! Everything else fades into insignificance.”

That evening, as the Germans menaced Bailleul, closed on the rail hub at Hazebrouck, and almost split the British First and Second Armies, BEF commander Douglas Haig issued one of the most dramatic communiqués of the war, an order of the day reading in part:

"Many amongst us now are tired. To those I would say that victory will belong to the side which holds out the longest. The French Army is moving rapidly and in great force to our support. There is no other course open to us but to fight it out. Every position must be held to the last man: there must be no retirement. With our backs to the wall and believing in the justice of our cause each one of us must fight on to the end. The safety of our homes and the freedom of mankind alike depend upon the conduct of each one of us at this critical moment."

As Haig indicated, the Allies couldn’t expect to stop the German onslaught without suffering considerable further losses in terms of casualties and territory. With British losses mounting, thousands of Flemish peasants fled their homes to avoid falling into German hands, and once again the countryside burned. On the night of April 13, Gibbs, the British war correspondent, recorded the firelit spectacle:

"It was a clear, starlight night, and for miles the horizon was lit by the flame of burning farms and stores and ammunition dumps, and all this pale sky was filled with the wild glare of fires and by the flash of guns. German air-raiders came out dropping bombs. The sound of their engines was a droning song overhead, and our shrapnel winked and flashed about them."

SHIFTING BALANCE

However, the situation was already turning against the Germans attackers. As the German offensive surged ahead in the middle, the left wing of the advance remained stuck near Givenchy to the south, and everywhere progress came at a heavy price, as in the first offensive. Though forced to retreat again and again, the defenders of the British First and Second Army fought fierce rearguard actions as they withdrew; the Germans faced major difficulties bringing up artillery and ammunition over wrecked battlefields to keep the offensive going. One German soldier, Franz Xaver Bergler, noted their stalled progress—as well as the generally miserable conditions—in his diary entry on April 12:

"We have been back in position since 3 April and are still here. Right in the midst of a completely devastated area, everything is shot into pieces, only grenade craters are left. We haven’t even started yet advancing against the English. The Englishman is just firing against us with his massive grenade fire all day long … Now we have been sitting in this position for eight days, often covered in mud and dirt up to the knees. We are freezing during the night and have no shelter. Or we are lying in an old tunnel, so tightly squeezed against each other that all limbs hurt terribly."

Disappointed by the Sixth Army’s failure to advance on the left, Ludendorff allowed a brief pause to resupply and move up artillery before resuming the attack all along the front. Over the next few days the Sixth Army encircled and captured the village of Bailleul together with the Fourth Army, while to the north the Fourth Army forced the British to withdraw from the area east of Ypres, won at such a terrible price in Passchendaele. However, the Germans didn’t notice the withdrawal right away, while the British received a boost with the arrival of more French reinforcements sent by Foch.

On the evening of April 16, as the German Fourth Army tried unsuccessfully to separate the British Second Army from the Belgian Army to the north, Gibbs described the long, curving inferno of the Ypres salient to the south, where British and ANZAC troops were staging desperate counterattacks against the advancing Germans:

"It was just before dusk that counter-attacks began northwards from Wytschaete southwards for Meteren, and although before then there had been steady slogging of guns and howling of shells, at that time this volume of dreadful noise increased tremendously, and drumfire broke out in fury, so that the sky and Earth trembled with it. It was like the beating of all the drums of the world in a muffled tattoo … It was a wet, wild evening, with few pale gleams of sun through storm clouds and smoke of guns, and for miles all this panorama of battle was boiling and seething with bursting shells and curling wreaths of smoke from batteries in action … When darkness came each battery was revealed by its flashes, and all fields around me were filled with red winkings and sharp stabs of flame."

To the south the Germans renewed their attack on Festubert and Givenchy, without success, although at a heavy cost to both sides. A British soldier, Lance Corporal Thomas A. Owen, described being wounded and taken prisoner near Festubert on April 18, 1918:

"Looking over the top I saw the long gray lines sweeping along 400 yards away. They were marching slowly, should to shoulder, heavily weighted with picks, ammunition, and rations. We scrambled to the fire-step. We fired madly and recklessly. The Lewis gun rattled and the two magazine fillers worked with feverish haste … Still the gray hordes advanced … I thought my arm had gone. If it was death I was numb, careless, and content. I sank into a dull stupor and the hordes of gray uniforms trampled over me, round me and by me, and forgot me in their own terror. They swept on and on to meet another wall of steel and flame. How many of them would see another dawn?"

By April 18 and 19 it was clear that the German offensive had run out of steam, but Ludendorff was determined to win some objective of strategic importance in order to justify the terrible bloodshed. In a renewed attack on April 25 the Germans captured Mount Kemmel, an important observation point for targeting artillery, in a brilliant tactical maneuver, but there weren’t enough troops to exploit the victory, allowing the British to reform defenses at a safe distance.

Meanwhile, to the south the Germans still hadn’t captured Festubert or Givenchy, spelling the end of the strategic plan for Operation Georgette. The other final thrust of the German offensive failed at the Second Battle of Villers-Bretonneux from April 24 to 26, 1918, again due to challenges with artillery and ammunition, and the intensifying defenses of the enemy. Dominik Richert, a German soldier from Alsace, described the German attack at Villers-Bretonneux on April 24, 1918:

"At a blow, more than 800 guns sent over their iron greetings and then went on and on; for a full hour the guns thundered and roared. The shells flew over us continuously. From the other side you could hear the individual shell bursts. It was almost impossible to communicate with each other. You had to shout the words in the other person’s ear … The artillery fired continued unabated, we could now hear the crackling of the rifles as well. The attack was in full swing. Wherever you looked it was crawling with German soldiers pushing forwards. Infantry, machine guns, small and medium-sized mortars were all moving forward. A swarm of German aircraft flew low over us in order to contribute to the success of the attack with bombs, hand grenades, and machine-gun fire. As we approached the corner of the wood there were already a number of dead lying on the churned-up ground. We were suddenly showered with a hail of artillery and mortar shells, and all jumped in the shell-holes or holes that had been dug by the men."

It soon became clear that this attempt was also doomed to failure, although commanders far from the battlefield were either isolated from this information or simply indifferent, according to Richert:

"As a result of the enormous losses the attack had ground to a stop. Everyone had sought cover in the numerous shell-holes. The whole area was constantly covered in black shell smoke. All at once officers and orderlies ran around the occupied holes and shouted: ‘Divisional orders: The attack must be continued!’ We were all appalled. Individual groups who had been driven out of their holes started to jump forwards. Our captain got out of a hole near us and ordered us to advance. What choice did we have?"

The German troops were undoubtedly exhausted. On the other side, on April 25, 1918, Philip Gibbs described German prisoners of war captured during the fighting at Villers-Bretonneux:

"Many of the others whom I now saw, and who lay down on the grass in every attitude of exhaustion, were bespattered with blood, which mixed in clots on the white dust of their clothes. The field in which they lay was all silver and gold with daisies and buttercups, and these heaps of field-gray men, in their grim helmets, which gave them a strange malignant look, spread themselves out on this lawn, and some of them slept until their sergeants shouted to them again, and they lined up for their rations."

By the time Ludendorff called off Operation Georgette on May 1, 1918, both sides had suffered another round of nauseating losses. On the Allied side, British casualties stood at over 80,000, including killed, wounded, missing, and prisoners, while the French suffered around 30,000 casualties, and the unfortunate Portuguese Expeditionary Corps was devastated by the loss of a third of its total strength. On the other side the Germans had suffered at least 85,000 casualties in all categories—an intolerably high price, drawing down significantly on the roughly million men freed up from the Eastern Front—in return for few strategic gains and no strategic breakthrough.

THE AMERICANS ARE COMING

In fact, the conquests would soon become a positive liability, as the Germans were left holding longer defensive lines while the Allies drew strength from the arrival of more and more American troops. By the end of April 1918 there were 434,081 U.S. troops in France, while 245,945 more would embark for the continent in May alone. Stateside, the massive construction and training program was producing vast numbers of fresh troops: By June 1918, the U.S. Army’s total strength would approach 2.4 million and counting.

Although the Americans naturally took some time to learn the vagaries of trench warfare, usually starting in a relatively quiet sector along their French and British allies, during the dark days of the first German offensive General Pershing had committed to sending American troops wherever they were needed in the Allied line. Floyd Gibbons, an American war correspondent, described the scenes as the doughboys (widely considered overpaid) passed through Paris while moving up to the line in France:

"Other American troop trains had preceded us, because where the railroad embankment ran close and parallel to the street of some nameless faubourg, our appearance was met with cheers and cries from a welcoming regiment of Paris street gamins, who trotted in the street beside the slow moving troop train and shouted and threw their hats and wooden shoes in the air. Sous and 50-centime pieces and franc pieces showered from the side doors of the horses’ cars as American soldiers, with typical disregard for the value of money, pitched coin after coin to the scrambling move of children."

After more than a year of waiting, ordinary British and French civilians were surprised and relieved to finally see the long-promised troops arriving in large numbers. Vera Brittain, a young British woman serving as a volunteer nurse’s aid in France, remembered her initial mystification on encountering doughboys for the first time:

"They were swinging rapidly towards Camiers, and though the sight of soldiers marching was now too familiar to arouse curiosity, an unusual quality of bold vigor in their swift stride caused me to stare at them with puzzled interest. They looked larger than ordinary men; their tall, straight figures were in vivid contrast to the undersized armies of pale recruits to which we had grown accustomed … 'Had yet another regiment been conjured out of our depleted dominions?' I wondered ... But I knew the colonial troops so well, and these were different; they were assured where the Australians were aggressive, self-possessed where the New Zealanders were turbulent. Then I heard an excited exclamation from a group of sisters behind me. 'Look! Look! Here are the Americans!' I pressed forward with the others to watch the United States physically entering the war, so god-like, so magnificent, so splendidly unimpaired in comparison with the tired, nerve-racked men of the British Army. So these were our deliverers at last, marching up the road to Camiers in the spring sunshine!"

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

Karolina Kristensson, the Swedish National Maritime Museums

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.

Vasa Diver

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.
