Sinking the “Fellowship of the Sea:” Lessons from Nuremberg for Future Naval Warfare

This article was submitted in response to the call for articles on the law of naval warfare jointly issued by CIMSEC and the Stockton Center for International Law at the Naval War College.

By Dennis E. Harbin, III

The “Fellowship of the Sea” and the Law of Naval Warfare

“…may humanity after victory be the predominant feature in the British Fleet.”—Vice Admiral Horatio Nelson’s prayer prior to the Battle of Trafalgar, 1805

One of the main purposes of the law of war is “protecting combatants, noncombatants, and civilians from unnecessary suffering.”1

Given the uniqueness of the operating environment, this purpose takes on a special meaning for the conduct of operations at sea and informs the body of international law known as the law of naval warfare. These laws codify and bind belligerents to restrain their use of violence with principles of military necessity, honor, humanity, distinction, and proportionality.2

In particular, that the principle of humanity animates the law of naval warfare has a lot to do with what Professor L.F.E. Goldie described as the “fellowship of the sea.”3 If humanity as a law of war principle “forbids the infliction of suffering, injury, or destruction unnecessary to accomplish a legitimate military purpose,”4 then the law of naval warfare — whether in the age of sail or the cyber age — must conform to this special fellowship. 

 How conflict in the future maritime security environment, with technological advancements such as artificial intelligence and unmanned robotics, will stress historical interpretations of the law of naval warfare is worth discussing. However, this concern isn’t new. As Professor Goldie reflected 31 years ago, “[s]hould a contest for mastery of the oceans come about under contemporary conditions, it would be awesome in its magnitude…[and] may also challenge their humanity.”5

In 2018, then-Chairman of the Joint Chiefs of Staff General Joseph Dunford declared that “[w]hile the fundamental nature of war has not changed, the pace of change and modern technology, coupled with shifts in the nature of geopolitical competition, have altered the character of war in the 21st century.”6

While the character of war may have changed, its violent nature and challenge to virtues of humanity has not. Therefore, despite new technologies that allow access to new domains, academics and practitioners should also reexamine historical situations as well. The intent of this article is to renew focus on the law of naval warfare related to submarines and their ability to preserve the “fellowship of the sea.” 

Specifically, whether modern armed conflict at sea has modified the submarine’s obligation to rescue survivors of targeted merchant vessels is worthy of consideration. This legal issue is unique in the law of naval warfare because it has been examined under the scrutinous light of litigation, yet remains “one of the least developed areas of the law of armed conflict.”7 To aid in understanding this 20th century legal issue in light of the 21st century maritime security environment, this article will call upon a historic milestone — the 75th anniversary of the International Military Tribunal (IMT) in Nuremberg. 

Naval Warfare on Trial at Nuremberg

“Over the last six decades, the word ‘Nuremberg’ has become synonymous with humankind’s highest ideals and aspirations — a measuring stick against which all subsequent humanitarian ventures have been measured.”8 This year marks the 75th anniversary of the International Military Tribunal (IMT), when 21 senior German political and military leaders were put on trial by the Allied Powers for violations of international law.9 

“There is no doubt that, with the benefit of over six decades of hindsight, we can say that the International Military Tribunal at Nuremberg (IMT) was an event of world-historical importance. It was the first successful international criminal court, and has since played a pivotal role in the development of international criminal law and international institutions.”10 From November 1945 to October 1946, testimony was heard and documents produced that ultimately resulted in judges from the United States, United Kingdom, France, and the Soviet Union finding 19 defendants guilty of some or all of the charges of crimes against peace, war crimes, and crimes against humanity. Herman Goering would commit suicide the night before he was to be executed. Ten would hang. 

At first glance, the Nuremberg experience may have little to do with naval warfare, especially submarine warfare in the future maritime security environment. After all, most view the atrocities committed by the Nazis through the lens of the devastation of an aggressive war on the European continent and the horrors of the Holocaust. The trial of Grand Admirals Raeder and Doenitz, however, are particularly informative to understanding the law of naval warfare – especially submarine warfare in the case of Grand Admiral Doenitz.

Grand Admiral Karl Doenitz began the war as the commander of the Kriegsmarine’s submarine fleet and would end the war as Hitler’s successor as Germany’s head of state for Germany. After the dissolution of the German government on May 23, 1945, Doenitz was arrested, imprisoned, and later charged on all three counts under the Nuremberg Charter — crimes against peace, war crimes, and crimes against humanity.11 Despite succeeding Hitler at the end of the war, Doenitz would be sentenced to only ten years in prison. He was found guilty of, inter alia, breaches of the international law of submarine warfare.

Relevant to this article, the IMT found that Doenitz violated the 1936 London Naval Protocol for ordering his submarine commanders not to rescue the crews of targeted merchant vessels.12 British prosecutor Sir David Maxwell-Fyfe intended to prove that Doenitz violated international law when, in early 1940, Doenitz prohibited his U-Boat commanders from rescuing after their attacks any civilian survivors in the water. Known as Standing Order 154, Doenitz was convicted for issuing the following:

“Do not pick up survivors and take them with you. Do not worry about the merchant ship’s boars. Weather conditions and the distance to land play no part. Have a care only for your own ship and think only to attain your next success as soon as possible. WE must be harsh in this war. The enemy began the war in order to destroy us, so nothing else matters.”13

For readers that may think decisions made by the Nazi Admiralty three-quarters of a century ago has little bearing on the operations of the United States or its Allies, consider one of the reasons why Doenitz — again, Hitler’s successor — was given such a relatively light sentence.

Fleet Admiral Chester Nimitz, the U.S. Pacific Fleet Commander during World War II, is well known for his leadership and strategic contributions in the Pacific theater. His contribution in the European theater — and specifically his impact on the punishments adjudicated in Nuremberg — is much less known and is one of the more fascinating stories of the consequential IMT.

How Nimitz came to be involved in the IMT was in no small part due to the litigation skills of Doenitz’s defense counsel, Otto Kranzbuehler. Looking closely at the photos taken during the trial, one may notice a German naval officer, in uniform, but not sitting in the defendant’s box. Otto Kranzbuehler served as the Kriegsmarine’s Fleet Judge Advocate (Flottenreichter) at Germany’s surrender. In an interview for the 50th anniversary of the IMT, he told the story of his discovery of a small book about the pacific war in an American library, and how it inspired him to involve Nimitz.14

After intense litigation, it was the American judge, Francis Biddle, who ultimately insisted that the interrogatories go to Nimitz and that his answers be entered into the record in defense of Doenitz. Through his forceful arguments and creative thinking, Flottenreichter Kranzbuehler was able to produce proof for the IMT that the 1936 London Naval Protocol was, in practice, operationally deficient. 

Specifically, when Kranzbuehler asked via interrogatory whether U.S. submarines were “prohibited from carrying out rescue measures toward passengers and crews of ships sunk without warning…,”15 Nimitz responded that “on general principles the U.S. submarines did not rescue enemy survivors if undue additional hazard to the submarine resulted or [if] the submarine would thereby be prevented from accomplishing its further mission.”16 Nimitz’s sworn response not only proved that the Allies were acting similarly to the Germans on this matter, but more importantly proved the impracticality of the law itself.

Despite what Doenitz declared as the “code of hardiness,” “which forswore every principle of the sea’s fellowship – mutual help in the face of nature, instant assistance to the shipwrecked, magnanimity in victory and fair play at all times,”17 the IMT did not include the waging of unrestricted submarine warfare when calculating his sentence due, in part, to Nimitz’s answers to Kranzbuehler’s interrogatories.18 When examined under the bright light of adversarial litigation, violating the 1936 London Naval Protocol which sought to enforce the “fellowship of the sea,” became an unpunishable offense.

State of the Law of Submarine Warfare

Before discussing how submarines will likely play a critical role in the future maritime security environment, it is helpful to examine the current state of the law by examining three relevant sources related to the law of naval warfare and submarine operations.

1. 1936 London Naval Protocol

A history of the 1936 London Naval Protocol is outside the scope of this article.19 The critical takeaways are threefold. First, the IMT used the Protocol to determine Grand Admiral Doenitz’s criminality. Second, submarines in their operations against merchant ships are obligated to adhere to the same visit and search, as well as rescue, rules for surface vessels. Specifically, the Protocol states: 

“In particular, except in the case of persistent refusal to stop on being duly summoned, or of active resistance to visit or search, a warship, whether surface vessel or submarine, may not sink or render incapable of navigation a merchant vessel without having first placed passengers, crew and ship’s papers in a place of safety. For this purpose the ship’s boats are not regarded as a place of safety unless the safety of the passengers and crew is assured, in the existing sea and weather conditions, by the proximity of land, or the presence of another vessel which is in a position to take them on board.”20

The final takeaway, particularly relevant to this article and for the application of the law of naval warfare in the future maritime security environment, is that while the United States remains legally bound to the terms of the 1936 London Naval Protocol, China does not. It neither signed the 1930 London Treaty nor the 1936 London Naval Protocol. 

2. The San Remo Manual on International Law Applicable to Armed Conflicts at Sea

Prepared by a group of “legal and naval experts…the purpose of the [San Remo] Manual is to provide a contemporary restatement of international law applicable to armed conflicts at sea.”21 Although non-binding, the San Remo Manual reiterates the foundational position that submarines are obligated by the same rules as surface ships.22 In practice, a submarine may only target an enemy merchant vessel if:

(a) the safety of passengers and crew is provided for; for this purpose, the ship’s boats are not regarded as a place of safety unless the safety of the passengers and crew is assured in the prevailing sea and weather conditions by the proximity of land or the presence of another vessel which is in a position to take them on board;

(b) documents and papers relating to the prize are safeguarded; and

(c) if feasible, personal effects of the passengers and crew are saved.23

3. The U.S. Navy Commander’s Handbook on the Law of Naval Operations

The U.S. Navy’s interpretation of the law of naval warfare related to submarine operations against merchants are consistent with the 1936 London Naval Protocol and the San Remo Manual. As a baseline, the Handbook still requires submarines to “search for and collect the shipwrecked, wounded, and sick following an engagement.”24

Although at first glance this may seem extreme relative to the realities of modern submarine warfare, the caveat to the rule is expansive. The Handbook continues, stating “If such humanitarian efforts would subject the submarine to undue additional hazard or prevent it from accomplishing its military mission, the location of possible survivors should be passed at the first opportunity to a surface ship, aircraft, or shore facility capable of rendering assistance.”25 Given that the purpose of the Handbook is to be of more practical usage to non-lawyer naval commanders, its discussion on these basic rules discussed above are particularly informative. Attempting to define circumstances that would “subject the submarine to undue additional hazard,” the Handbook lists the following examples: 

    1. The enemy merchant vessel persistently refuses to stop when duly summoned to do so. 2. It actively resists visit and search or capture. 
    2. It is sailing under convoy of enemy warships or enemy military aircraft. 
    3. It is armed with systems or weapons beyond that required for self-defense against terrorism, piracy, or like threats. 
    4. It is incorporated into, or is assisting in any way the enemy’s military intelligence system. 
    5. It is acting in any capacity as a naval or military auxiliary to an enemy’s armed forces. 7. The enemy has integrated its merchant shipping into war-fighting/ war-supporting/ war-sustaining effort, and compliance with the London Protocol of 1936 would, under the circumstances of the specific encounter, subject the submarine to imminent danger or would otherwise preclude mission accomplishment.26

Submarines and Merchant Vessels in the Future Maritime Environment

Upon examining the law of naval warfare related to submarines, an author in the U.S. Naval War College’s International Law Studies concluded more than 20 years ago that “it is highly probable that in any World War III belligerents will again find reasons why the 1936 London Submarine Protocol should not be applied…[and] in any future armed conflict of lesser extent than a World War III, the pressure of neutral Powers may be sufficiently strong to cause the belligerents to comply with the provisions of the 1936 London Submarine Protocol.”27

The reliance on submarines in future naval warfare is a cornerstone of the U.S. Navy’s plan to implement integrated, all-domain naval power. The Chief of Naval Operations, Admiral Michael Gilday has recognized that “the advantage we have in the undersea [environment] is an advantage that we need to not only maintain, but we need to expand.”28 His 2021 Navigation Plan acknowledges that, in order to “deliver the all-domain naval power America needs to win…the Navy requires a greater number of submarines….”29 Moreover, the Navy’s Battle Force 2045 reflects the importance of submarines in the changing character of war as well.

Then-Secretary of Defense Mark Esper remarked that “there was clear consensus over months of study and war-gaming and analysis that we need to build more submarines, more attack submarines. And if we do nothing else we should invest in attack submarines, because of the lethality that they can deliver under the sea and the survivability that they have in clear overmatch that we have when it comes to the under sea domain and submarines in particular.”30 This focus has transferred across Presidential administrations as well. As reported recently, “as the [Biden] White House positions itself to argue on behalf of its budget proposal, new attack submarines apparently are a top priority.”31

The United States is not the only great power investing in its submarine force.32 The Chinese are also investing heavily in their future submarine fleet as well.33 As reported in October 2020, satellite images showing expansive building at a Chinese naval shipyard confirms the Office of Naval Intelligence’s forecast that “China’s submarine fleet [will] grow by six nuclear-powered attack submarines by 2030.”34

In addition to the likely critical role submarines will play in the next maritime war, its impact on commerce and trade will be tremendous. As an American naval officer testified during the IMT 75 years ago, “commerce and trade are now so identified with military power in total warfare that merchant ships, armed or unarmed, are in effect warships to be attacked and sunk without warning.”35

One-third of global commerce transits the South China Sea, arguably the world’s most contested maritime security hot spot.36 “As the second-largest economy in the world with over 60 percent of its trade in value traveling by sea, China’s economic security is closely tied to the South China Sea.”37 Given China’s and the U.S.’s reliance on commercial shipping in that area, it is not difficult to imagine that merchant vessels will once again be the targets of submarines in future maritime warfare. 


It is difficult, however, to imagine a nuclear submarine surfacing to take on survivors. The impracticability of this practice was evident during the IMT proceedings when Flottenreichter Kranzbuehler produced Nimitz’s sworn responses and the Allies failed to punish Doenitz for violating the 1936 London Naval Protocol, which in effect ended the “fellowship of the sea.”

 It is also not difficult to imagine that the “fellowship of the sea,” at least when it relates to submarine warfare, will continue to erode in the future maritime security environment. In fact, Nimitz is believed to have declared during the IMT that the “United States would probably wage unrestricted submarine warfare in future naval wars, based on its success in the Pacific War.”38

Maintaining rules that are impractical and operationally unrealistic undermines the rule-of-law. The IMT experience 75 years ago suggests that, when examining the law of naval warfare in the future maritime security environment, policy-makers must consider how keeping old rules may do more harm than good. As maritime security tensions again arise in the Pacific, where emerging technologies give commanders greater capability while requiring them to think faster, we need realistic rules and expectations that reflect operational realities. However, because the principle of humanity is a cornerstone of the law of naval warfare, policy-makers and commanders must strike a balance and strive to make and interpret rules that continue to uphold the centuries-old “fellowship of the sea.”

CIMSEC is proud to partner with Lockheed Martin and the U.S. Naval Postgraduate School’s Naval Warfare Studies Institute on the final topic of Project Trident: Emerging Technologies. Lockheed Martin is a global security and aerospace company responsible for many Defense Department programs of record. The Naval Warfare Studies Institute (NWSI) coordinates NPS inter-disciplinary research and education to accelerate and enhance the development of capabilities and warfighting concepts.

The modern world is shaped by few forces as powerful as rapid technological change. As the world becomes ever more advanced, technological change cuts across and interconnects areas as diverse as healthcare, public infrastructure, and security policy. With respect to national security, new technology is presenting opportunities for novel warfighting capabilities, ever more powerful iterations of familiar weapons systems, and unexpected avenues for threats. The maritime community must attentively explore how new and emerging technologies will impact maritime security and naval capabilities.

Computing power, connectivity, data analytics, and machine learning are poised to undergo exponential growth in ways once consigned to the realms of science fiction. What implications do specific technologies like augmented reality, artificial intelligence, or 5G have for maritime security and navies? Which emerging technologies have potential for significant security impacts yet remain underrated? How can a government, a navy, or a shipping company keep pace with global information flows that update in near-real time? How do maritime actors stay abreast of these changes while leveraging them for competitive advantage and avoiding the risks of over-reliance? The spectrum of civil and military emerging technologies have salient overlaps that will present complex challenges to maritime security.

Authors are encouraged to address these questions and more as we contemplate the promise and pitfalls of emerging technologies on maritime security. Send all submissions to

Project Trident Call for Articles: The Law of Naval Warfare

The Stockton Center for International Law (SCIL) at the U.S. Naval War College is partnering with CIMSEC to launch the latest Call for Articles of Project Trident to solicit writing on the law of naval warfare and its evolving impact on the future of international maritime security. SCIL is a leading research institute for the study of international law and military operations that produces original analysis for national decision-makers, senior military leaders, scholars, and legal practitioners throughout the world in order to better grasp the role international law plays in naval, joint, and combined operations. The Stockton Center also publishes International Law Studies, the oldest journal of international law in the United States.

The threat of armed conflict at sea is ever-present. Emerging naval technology, new operational, force employment, and warfighting concepts, and contending interests in the oceans risk undermining maritime security. In peacetime, the majority of seafaring States abide by the law of the sea most of the time, either as a matter of customary international law or as a party to the United Nations Convention on the Law of the Sea (UNCLOS) and other agreements. During armed conflict, states apply the law of naval warfare. Yet much of the law in this regard was developed at the Hague Conference in 1907 and by state practice during the world wars. There has been no new codification of the law of naval warfare since Geneva Convention II in 1949. In the event of armed conflict at sea today, states must apply these legacy rules to new situations, making their application and legal outcome uncertain. Furthermore, current naval forces, maritime law enforcement organizations, and state-sponsored maritime militia promote different approaches to the principles and norms of customary law.

New technology continues to transform the maritime domain. The inherently interconnected nature of cybersecurity and the increased risk that comes with autonomous unmanned platforms could pose legal challenges in conflict. Gray-zone operations just below the threshold of declared armed conflict are deliberately taking advantage of legal ambiguities, and the definition of a combatant, or hostile act or intent, is becoming more and more blurred. Maritime militia, coast guard vessels, armed merchantmen, and civilian-crewed military logistics vessels can all present legal complications in a naval warfare context. With respect to tactics and operations, warships may feel compelled to blend with civilian traffic to decrease their detectability and take advantage of the element of surprise. On the strategic level, nations may choose to employ blockades, minefields, and other measures that present legal challenges.

In the future, will today’s definition of armed conflict at sea remain relevant? Who will be considered belligerents, and who (or what) will be considered valid targets? What activities will constitute an attack? International law and its application must evolve to reflect the changing realities of naval warfare with the emergence of new technologies and gray-zone activities.

Authors are invited to write on these topics and more as we look to understand the interplay between evolving laws surrounding naval warfare and the future of international maritime security. Submissions will be jointly reviewed and approved by CIMSEC and SCIL, and will be reviewed for quality of writing, analysis, and legal rigor.

Project Trident Call for Articles: Maritime Infrastructure and Trade

Week Dates: May 3-7, 2021

By Jimmy Drennan

CIMSEC is partnering with Maersk Line, Limited to launch the Project Trident call for articles on maritime infrastructure and trade! Maersk Line, Limited provides end-to-end transportation solutions to support the unique requirements of the U.S. government. As the largest owner and operator of U.S. flag vessels trading internationally and the largest participant in the VISA/MSP programs, these network ensures reliable and regular connection to all corners of the globe.

Security and prosperity go hand-in-hand, and as the complexity of the global economy grows, so too does its dependence on the maritime domain. The increasing connectedness of national and regional economies, combined with the COVID-19 pandemic, have highlighted the importance of infrastructure and trade in maritime security.

Last year, shipping carriers rejected U.S. agricultural exports worth hundreds of millions of dollars in favor of returning empty containers to China, which faces a container shortage due to a surge in consumer goods. Government stimulus packages and shifting consumer trends resulting from the pandemic have put a strain on global container capacity, and China is making it more profitable for shippers to bring back empty containers than American agricultural exports. Meanwhile, containers full of American goods stack up in slammed ports like Los Angeles and Long Beach. The growing intricacies of the global supply chain demonstrate the need for a coordinated maritime strategy.

Port capacity and accessibility is rapidly changing as the developing world increasingly becomes more urbanized and developed, thereby increasing their demand of the global maritime commons. The volume of commercial maritime traffic is ever increasing, and the ability of ports to keep pace is in flux. Ports have significant geopolitical value as well, especially as China is securing long-term leases on port infrastructure beyond its borders.

The global shipbuilding industrial base remains heavily concentrated in China, Japan, and South Korea, which account for around 90 percent of all ships launched in recent years. In 2018, the world’s global merchant fleet totaled 50,000 vessels with a combined value of $851 billion, and a total deadweight tonnage of 1 billion. The shipbuilding industrial base in the United States is dominated primarily by military shipbuilding contracts while large-scale commercial shipbuilding capacity has largely gone overseas. The shipbuilding industrial base of China, both commercial and military capacity combined, is overshadowing that of the United States, raising questions about their respective abilities to mobilize industry in a time of conflict.

Often overlooked is the critical, but often opaque world of shipping finance and insurance. For example, China is rapidly becoming the preferred option for ship financing as western banks exit the market space. U.S. Military Sealift Command contracts with foreign tanker companies to charter ships for some overseas operations. These ships are sometimes leased to tanker companies from Chinese banks, with little to no awareness by the U.S. government.

Data is the new lifeblood of global commerce and the shipping industry is in the midst of a digital revolution. The industry is looking to seize opportunities posed by emerging technologies and networks, but must be considerate of the associated cybersecurity concerns and the risks of failing to keep pace with change.

CIMSEC wants your ideas on how infrastructure and trade will impact the future of international maritime security. What could be the maritime security impacts of Sino-American economic interdependence, changing infrastructure capacity, rapid port development, decarbonization, digital revolution, and other trends and facets of global maritime infrastructure?

Authors are invited to answer these questions and more as we consider the future of maritime infrastructure and trade. Send all submissions to
