The Cargo in Hold Number Four

Three years before the customs officer George S. Kretschmar would examine the cargo manifest in New York, the questions raised by the Admiralty’s silent files had already begun to migrate — into the cargo manifests, the hold inventories, the lists of what the Lusitania had been carrying besides passengers. On the morning of 10 May 1915, three days after the Lusitania went to the bottom off the Old Head of Kinsale, Kretschmar sat down with the ship’s supplementary cargo manifest — the second, shorter list filed with the Collector of Customs before departure — and confirmed what he already knew.

Kretschmar had seen it before the sailing. So had the customs house. So had the Cunard Line. Nobody had hidden it. Nobody needed to. The cartridges were legal cargo under American law, declared and documented, stamped and counted, and the Lusitania was a British-registered vessel sailing into a war zone where such cargo was entirely routine.

That same morning, the Cunard Line issued its first detailed public statement about the disaster. The statement, carried by the London press and reproduced in the New York papers, described the Lusitania’s cargo as ordinary commercial goods of the kind customary in peacetime trade. No mention of ammunition. No mention of rifle cartridges. No mention of the 4, 200 cases that Kretschmar’s manifest recorded with bureaucratic precision. The line between those two facts — one private, one public, both issued within hours of each other on opposite sides of the Atlantic — was the line along which the entire moral and legal case for the sinking would be fought for the next three years.

While the Admiralty files stayed locked, attention turned to the physical evidence, downward into the ship’s belly, into the holds where the cargo rested in darkness under sixty feet of Irish water. But the cargo had been there all along. Present when the passengers boarded at Pier 54. Present when the German Embassy inserted its warning advertisement in the New York papers on the morning of sailing. Present when the ship crossed the Atlantic and when the torpedo struck. The unseen cargo was not a secret discovered after the fact. It had been known before the fact, rendered invisible by the needs of the moment.

In Berlin, on 8 May, the former German colonial secretary Bernhard Dernburg — functioning as an unofficial spokesman for the German government, since he held no official post — told reporters in Cleveland, Ohio, that the Lusitania carried contraband of war and was classed as an auxiliary cruiser. Dernburg’s timing was precise. He spoke before the American public had fully absorbed the scale of the disaster, before the bodies had been catalogued in the Queenstown sheds, before the Mersey inquiry had been convened. His claim rested on two assertions: that the ship carried munitions, and that the ship was a warship. The first assertion was true. The second was not. But the two traveled together, and their pairing made the first harder to dismiss and the second harder to refute.

Dernburg’s statement landed in an American press already divided. The New York Times called the sinking mass murder. German-language newspapers in New York called it a legitimate act of war against a vessel carrying contraband through a declared war zone. The split was not along party lines or even along ethnic lines. It ran through the American public’s own uncertainty about what the United States was, or should be, in a world at war. A nation that had declared itself neutral was shipping ammunition to one belligerent. The contradiction was not lost on anyone.

In Whitehall, the response to Dernburg was managed with care. The British position, formulated in the days between 10 and 13 May by officials at the Foreign Office and the Admiralty, held that the presence of small-arms ammunition aboard the Lusitania did not alter the ship’s status as a noncombatant vessel. The cargo was contraband, yes. But contraband did not make a passenger liner a military target. Under the Cruiser Rules — the international code governing naval warfare that both Britain and Germany had signed — a warship could stop a merchant vessel, search it, and seize contraband. It could not sink it without warning and without provision for the safety of passengers and crew. The rules were clear on this point. They had been clear for decades.

The problem was that the rules had been under strain since the first day of the war. Britain had mined the North Sea. Germany had declared submarine warfare around the British Isles. The Cruiser Rules assumed surface vessels that could board and inspect. A submarine could not board a ship of the Lusitania’s size, could not take prisoners, could not accommodate a prize crew. The rules, designed for an earlier era of naval combat, had been outrun by the technology of the submarine and the doctrine of unrestricted warfare. This did not excuse the torpedo. But the legal argument grew more brittle than either side wished to admit.

Within Cunard, the response to the cargo question was shaped by a different pressure. The line faced potential liability claims from the families of American passengers. If the Lusitania had been carrying munitions through a declared war zone, and if passengers had not been informed of that fact, then the line’s duty of care, the legal obligation to warn passengers of known risks, became a live question. Cunard’s lawyers understood this. The company’s managers, including the general manager Harold Sanderson and the chairman Sir Alfred Booth, understood it too. The public statement describing the cargo as ordinary merchandise served as a legal position, a hedge against future claims.

The manifest told a different story. The supplementary cargo list, filed in New York, recorded the 4, 200 cases of Remington. 303 cartridges. Also recorded were 1, 250 cases of shrapnel shells, empty, with fuses separately packed. And 18 cases of non-explosive fuses. The total was modest by the standards of a transatlantic munitions trade that had been running since the previous autumn. But not zero. Not ordinary merchandise. War materiel, shipped under commercial contract, declared to customs, insured against loss, and loaded into the holds of a passenger liner carrying 1, 959 people.

The distinction that British and American officials would draw, and that they drew repeatedly in the weeks that followed, was that the cargo did not remove the passengers’ right to safety. The British government and the Wilson administration took this position. The position was not that there was no war materiel aboard. Rather, that what was present did not justify the killing of civilians. The legal argument was sound. The moral argument was strong. The political argument was complicated by the simple fact that the public had been told, repeatedly and by official sources, that the ship carried no munitions. When that statement proved to be inaccurate, and it proved inaccurate within days, the credibility of every subsequent official claim was diminished.

The German Embassy in Washington moved quickly. Count Johann von Bernstorff, the German ambassador, had authorized the warning advertisement that appeared in the New York papers on 1 May. The advertisement, placed alongside the Cunard sailing notice, warned travelers that the waters around the British Isles were a zone of war and that vessels flying the British flag would be destroyed. American citizens were advised not to travel on British ships. The advertisement had been seen by many of the passengers who boarded the Lusitania that morning. Most had dismissed it. Some had not seen it at all.

Now, in the days after the sinking, Bernstorff and his staff assembled the case. The warning had been given. The war zone had been declared on 18 February. The ship carried contraband. The ship was British-registered and under the control of a belligerent power. Under the German reading of the law, these facts combined to make the Lusitania a legitimate target. The argument was not without merit. Not without precedent. But it collided with a simpler and more powerful fact: 1, 198 people had drowned, including 128 Americans, and 94 of the dead were children.

The German Foreign Office, under Chancellor Theobald von Bethmann Hollweg, was not unified on the submarine question. Bethmann Hollweg had opposed unrestricted submarine warfare from the beginning. He feared it would draw the United States into the war. He was overruled by the military — by Admiral Alfred von Tirpitz, the architect of the German Navy, and by Admiral Gustav von Bachmann, the Chief of the Naval Staff. Tirpitz saw the Americans as no threat. He believed that a decisive submarine campaign against British shipping would end the war before the United States could mobilize. He pushed for the official German line on the munitions issue, focusing public argument on the Lusitania’s cargo as proof that the ship was a legitimate military target.

The internal German debate concerned strategy, not morality. Bethmann Hollweg feared the political consequences. Tirpitz dismissed them. The Kaiser, Wilhelm II, wavered. In the immediate aftermath of the sinking, the German press celebrated. Newspapers in Berlin called it a brilliant success. The Catholic press in Cologne praised the submarine commander. The celebration was public and unembarrassed. It was also, in the assessment of the German Foreign Ministry’s own officials, a strategic disaster. Every celebration made the American case stronger. Every boast about the cargo made the dead seem more like victims and less like collateral damage.

The Admiralty in London watched the German response with a mixture of outrage and relief. Outrage, because the German argument threatened to muddy what the British saw as a clear case of atrocity. Relief, because the cargo question gave the Admiralty its own distraction. If the public debate centered on whether the Lusitania carried munitions, then it would not center on whether the Admiralty had failed to provide the ship with an escort, or whether Room 40’s intercepts had been acted upon, or whether Captain Turner had been given the intelligence he needed. The cargo question was a problem for Cunard and for the Foreign Office. The operational questions were a problem for the Admiralty. Winston Churchill, then First Lord of the Admiralty, understood the distinction. He let the cargo question run.

The American investigation into the cargo began almost immediately. The Treasury Department, which oversaw customs, pulled the Lusitania’s manifest from the New York files. The document confirmed what Kretschmar had already noted. The 4, 200 cases were there. The shrapnel cases were there. The fuses were there. The manifest had been filed in accordance with American law. The cargo had been inspected. The shipment was legal. None of this was hidden. It was simply not publicized.

Secretary of State William Jennings Bryan, who had been arguing since the war began that the United States should prohibit American citizens from traveling on belligerent ships, saw the cargo revelation as confirmation of his position. Bryan was not a lawyer and not a diplomat by training. He was a moralist. He believed that Americans who traveled on British ships through war zones were taking risks that the United States government was not obligated to underwrite. He believed that American companies shipping munitions to belligerents were compromising American neutrality. The Lusitania’s cargo confirmed both beliefs. Bryan raised the issue in Cabinet meetings. He was overruled by President Wilson, who insisted that the right of Americans to travel on the high seas was absolute and non-negotiable.

The tension between Bryan and Wilson was not resolved by the cargo evidence. It was sharpened by it. Bryan believed the cargo made the American protest note to Germany weaker, not stronger. If the ship carried munitions, the German argument that it was a legitimate target gained force. Wilson believed the cargo was irrelevant to the principle at stake. The principle was that noncombatants, passengers, women, children, could not be lawfully killed regardless of what the ship carried in its holds. Both men were right in their own frame. Both frames were insufficient.

The RMS Lusitania had been launched by the Cunard Line in 1906 as a Royal Mail Ship. She was the world’s largest passenger ship until the completion of her sister Mauretania three months later. In 1907, she gained the Blue Riband appellation for the fastest Atlantic crossing. Built with Admiralty subsidy, her engine rooms were designed to Admiralty specifications. She was listed in the Admiralty’s confidential handbook as an armed merchant cruiser, available for naval service in time of war. She had been fitted with gun mounts, though no guns were installed for her final voyage. These facts were known to the Admiralty. Known to Cunard. Not known to the passengers who bought tickets at the Cunard office on Broadway.

The gun mounts were a particular problem. The German Embassy had alleged that the Lusitania was equipped with masked guns, supplied with trained gunners and special ammunition. The allegation was false. No guns were mounted. No gunners were aboard. No special ammunition was carried. But the gun mounts existed, and the Admiralty’s listing of the ship as an auxiliary cruiser existed, and the Admiralty subsidy existed. Each fact made the German allegation harder to dismiss as pure fabrication. The allegation was not fabrication. It was exaggeration grounded in partial truth.

The cargo in the holds was not the cause of the second explosion. This was a question that would be asked repeatedly. The second explosion, the one that followed the torpedo detonation and that accelerated the sinking from what might have been survivable damage to a catastrophic one, was variously attributed to a boiler explosion, a coal dust explosion, or the detonation of cargo munitions. The cargo of rifle cartridges was not a likely cause. Small-arms ammunition does not detonate in bulk. It burns. The burning might produce heat and smoke, but would not produce the single massive concussive blast described by survivors. The shrapnel shells were empty. The fuses were non-explosive. The cargo, while military in nature, was not the kind of high-explosive material that would produce a secondary detonation of the magnitude observed.

But the question persisted. It persisted because the second explosion was the mechanism by which the sinking became unsurvivable. If the torpedo alone had been the cause, the ship might have stayed afloat long enough for the lifeboats to be launched properly. The second explosion was what turned a crisis into a catastrophe. And the presence of military cargo in the holds, regardless of its actual explosive potential, made it easy to believe that the cargo was responsible. The belief was understandable. Also, on the available evidence, wrong. But the Admiralty did not correct it. Did not address it. Let the speculation run, because the speculation served a purpose. If the public believed the second explosion was caused by the cargo, then the Admiralty’s own failure to protect the ship was less visible. The cargo became the explanation. The Admiralty’s silence became invisible.

In the first two weeks of May 1915, the cargo question moved from the customs house in New York to the front pages of the world’s newspapers. The German propaganda machine, centered in Berlin and operating through embassies and unofficial spokesmen, seized on the manifest as proof. Dernburg’s statement was followed by official German notes and by newspaper articles in the German press. The notes argued that the Lusitania was an auxiliary cruiser carrying contraband, that the German Embassy had warned passengers, and that Germany bore no responsibility for the deaths of those who chose to travel on a belligerent ship through a declared war zone.

The British counter-argument, advanced through the press and through diplomatic channels, held that the cargo was irrelevant. The ship was a passenger liner. The passengers were noncombatants. The torpedo was fired without warning. The sinking was an act of piracy. This argument was emotionally powerful and legally defensible. But it was undermined by the initial public statements denying the cargo’s existence. The denial had been issued. The denial was false. The correction, when it came, was quiet and indirect. The damage to credibility was done.

Cunard’s position was the most exposed. The line had issued the statement calling the cargo ordinary merchandise. The manifest contradicted the statement. Lawyers for the line knew this. Managers knew this. The chairman knew this. The question was whether to correct the record or to let the statement stand. The decision, made in the days after the sinking, was to let the statement stand in public while acknowledging the cargo in private communications with the Admiralty and the Foreign Office. The decision was a calculation, not a conspiracy. The calculation was that the public outrage over the sinking would overwhelm the cargo question, and that the cargo question would fade as the larger diplomatic crisis between Washington and Berlin took center stage.

The calculation was partly correct. The diplomatic crisis did take center stage. President Wilson’s notes to Germany, drafted in the weeks after the sinking, demanded an explanation and a disavowal. The notes did not mention the cargo. Wilson’s advisers, including Counselor Robert Lansing, understood that the cargo was a vulnerability. Lansing, who would succeed Bryan as Secretary of State in June, believed that the American position must rest on the principle of noncombatant immunity, not on the absence of munitions. The distinction was crucial. If the American case depended on the ship being unarmed and carrying no war materiel, then the case would collapse when the cargo was revealed. If the case depended on the principle that civilians could not be lawfully killed regardless of what the ship carried, then the case would survive the cargo revelation.

Lansing chose the second approach. Wilson agreed. The notes to Germany were framed in terms of principle, not fact. The principle was that the United States expected Germany to respect the lives of noncombatants on merchant vessels, regardless of the flag flown or the cargo carried. This was a strong position. It was also a position that the United States would find difficult to maintain if American companies continued to ship munitions on passenger liners through war zones. The contradiction was not lost on the Germans.

The cargo became a deployed fact. It appeared in German diplomatic notes. In German newspaper articles. In the arguments of American isolationists and German-American organizations. In the private correspondence of British officials who acknowledged its existence while minimizing its significance. In the testimony that would be given at the Mersey inquiry, where the manifest would be entered into evidence and where the question of what the ship carried would be asked and answered under oath.

The cargo was not the cause of the sinking. The torpedo caused the sinking. The cargo was not the cause of the second explosion. The second explosion was caused by something else, probably a boiler or a steam line, though the precise mechanism would never be definitively established. The cargo was not the reason the passengers died. The passengers died because the ship sank in eighteen minutes, because the lifeboats could not be launched in time, because the list made the boats unusable, because the water was cold and the coast was far. The cargo did not kill anyone.

But the cargo changed what the sinking meant. Changed it from a simple act of barbarism into a complex act of war. Gave the German government an argument that was not wholly without merit. Gave the American government a vulnerability that it could not afford to acknowledge. Gave the British government a distraction that it was content to exploit. And gave the dead a context that they had not chosen and would not have wanted. The 4, 200 cases of rifle cartridges in Hold Number Four did not cause the disaster. But they became part of it. The fact that the disaster could not shed.

By 15 May, the cargo question had been asked in every major newspaper in the Western world. The answers varied. The New York Times acknowledged the ammunition but argued that it did not justify the attack. The London Times denied that the ammunition was significant. German newspapers in Berlin called the ammunition proof that the ship was a legitimate target. German-language papers in New York called the American protest hypocritical. Every answer was shaped by the political needs of the answerer. Every answer was partial. The manifest itself — the document that listed the cargo in plain type — was the only complete answer, and it sat in a customs house file in New York, available to anyone who asked.

Few asked. The manifest was not secret. It was simply not interesting until the sinking made it interesting. The same line entry that had been routine on 1 May became explosive on 8 May. The same 4, 200 cases that had been loaded without comment became the subject of diplomatic notes and legal arguments and propaganda campaigns. The cargo had not changed. The context had changed. And the context was the disaster itself: the 1, 198 dead, the children among them, the bodies in the Queenstown sheds, the families waiting for news that would not come.

The cargo question would persist. Raised at the Mersey inquiry, where Lord Mersey would hear testimony about the manifest and the holds. Raised in the diplomatic correspondence between Washington and Berlin. Raised in the American press and in the British press and in the German press. Raised in the years that followed, when the question of what the Lusitania carried became entangled with the question of why the Admiralty had not protected her, and whether the protection was withheld deliberately, and whether the ship was meant to be a casualty that would draw the United States into the war.

There is no evidence that the Admiralty withheld protection in order to create a casualty. The evidence shows something less dramatic and more troubling: that the Admiralty failed to protect the ship through a combination of operational distraction, intelligence hoarding, and institutional indifference. The cargo did not cause that failure. But the cargo complicated the failure’s aftermath. Made the Admiralty’s position harder to defend, because it raised the question of why a ship carrying munitions through a war zone was not given an escort. Made Cunard’s position harder to defend, because it raised the question of why passengers were not told what was in the holds. Made the American government’s position harder to defend, because it raised the question of why American neutrality permitted the shipment of war materiel on passenger vessels.

The cargo was a fact. It sat in the manifest, in the customs file, in the hold of the sunken ship. Not a theory or a suspicion or a conspiracy. A line entry. Four thousand two hundred cases of rifle cartridges. And by the middle of May 1915, that line entry had become a weapon in a propaganda war that was being fought as fiercely as the war itself, a weapon that Germany would deploy in its diplomatic notes and its newspaper editorials and its public statements, a weapon that Britain and the United States would struggle to deflect, and a weapon that would, in the end, make the moral landscape of the disaster irreversibly complex.

The dead had not known what rested below their feet. The governments that mourned them had known, and had said nothing, and now the silence was breaking apart, and what emerged from it was not exoneration but a deeper reckoning, one that would send investigators down into the holds and the names and the cost, where the next phase of accounting had already begun.
