Fighting on the water for trade routes, territory or plain power and glory is as old a concept as there is when it comes to war. 

Naval powers have also used various types of vessels to punish their enemies, from old wooden ships to the steel monsters of the battleship era of years past to aircraft carriers to the smaller but still dangerous cruisers and destroyers of today. 

But if we were to survey history, what were the biggest, most important naval battles in all of history? And, if we wish to be more specific, what are the most important battleship battles as well? 

Back by popular demand, we present two of our most popular pieces, authored by James Holmes and Robert Farley, packaged together in this one posting for your reading pleasure. What ships won the day? What vessels sunk to the bottom of the sea? What naval battles made the most history? Let the debate begin. 

***

Ranking battles by their importance has been a bloodsport among military historians as long as there have been military historians. Creasy's classic Fifteen Decisive Battles of the World(1851) set the standard for the genre.

But what makes a battle decisive? And what makes one such test of arms more important than another?

Defining the term too loosely produces howlers like a recent US News catalogue of decisive battles of the American Civil War. By the US News count, 45 engagements qualified as decisive during that four-year struggle alone. Zounds!

The term must be defined less cavalierly than that to be meaningful. If every battle is decisive, no battle is. That's one reason I always ask students whether some legendary triumph—a Trafalgar, or a Tsushima Strait—was decisive, or just dramatic, or just featured the star power of a Nelson or Togo.

Even the masters of strategy, however, appear ambivalent about what constitutes decisive victory. Carl von Clausewitz supplies a working definition, describing a decisive engagement as one that leads directly to peace. This implies an action carrying not just tactical but strategic and political import. Such an encounter impels the vanquished to accept the victor's terms at the bargaining table, whether because he's no longer capable of fighting on, believes he stands little chance of turning the tables and winning, or estimates that victory will prove unaffordable. A decisive battle, in this expansive interpretation, is the chief determinant of a war's outcome.

So far, so good. But how direct must direct be for a battle to earn the lofty status of decisive? Must peace talks take place immediately following the clash of arms that precipitates them? Can a settlement come weeks or months afterward, so long as the cause/effect relationship is clear? What's the time horizon?

The great Carl is silent on such matters. It's possible he's too casual about them. Combat, methinks, can be decisive while achieving more modest goals than winning a war outright. To see how, interpret the word literally: something decisive decides something. (Admittedly, this is probably how the US News team got in trouble. Every action decides something in a tactical sense, no matter how mundane or inconsequential. If nothing else, it determines who holds the field of battle at day's end, or reveals that the fighting stalemated. This says little about its larger meaning, if any.) Armed clashes can yield decisive results on different levels of war. A tactical encounter could decide the outcome of a campaign or the fate of a combat theater without leading directly to peace. Right?

In short, it appears wise to define a decisive victory more three-dimensionally than Clausewitz does, namely as a trial of arms that lets a belligerent accomplish some positive or negative aim beyond mere tactical results. Winning the war would still qualify, obviously, but the broader view would allow historians to rate a Battle of Trafalgar as decisive.

Fought in 1805, Trafalgar scarcely brought about final peace with Napoleonic France. That took another decade of apocalyptic warfare. But it did settle whether the French could invade the British Isles and, through amphibious conquest, crush the offshore threat to French supremacy. The heroics of Nelson, Collingwood, and their shipmates decided the outcome of Napoleon's scheme while enabling Great Britain to persevere with the struggle. Trafalgar, then, directly accomplished the negative goal of keeping French legions from invading Britain. That must qualify as decisive in the operational sense.

Speaking of pugilism on the briny main, here's another wrinkle in this debate. Clausewitz says next to nothing about maritime conflict. Water barely exists in his writings. Fin de siecle historian Sir Julian Corbett, the best in the business of sea-power theory, doubts naval warfare is ever decisive by itself, except perhaps through gradual exhaustion. Close or distant blockades, however, grind down not just the enemy but your allies and your own businessfolk who rely on seaborne trade. They impose costs on everyone.

Like Clausewitz, Corbett thus seems skeptical about the decisiveness of any single engagement. Sure, a dominant seafaring state can and must make the sea a barrier to invasion and other direct assaults on its homeland. That's the Trafalgar model. At its bottom, though, maritime strategy is the art of determining the relations between the army and navy in a plan of war. It's ultimately about shaping affairs on land, which, after all, is where people live. But how do you rank a purely naval engagement on the high seas against an army/navy operation that unfolds at the interface between land and sea?

Tough question. So there's a lot to ponder in the seemingly simple question, what is decisive? To rank naval battles against one another, let's assign a pecking order among degrees of decisiveness. Derring-do, tactical artistry, or gee-whiz technology are not among the criteria. Nor are lopsided tactical results enough to lift an encounter into the upper echelon. That's why the Battle of Tsushima, which left wreckage from the Russian Baltic Fleet littering the Yellow Sea floor in 1905, doesn't make my list.

Topping my list are naval actions that decided the fates of civilizations, empires, or great nations. This is decisiveness of the first order. Such encounters stand in a category apart. Next come engagements that reversed the momentum in a conflict of world-historical importance. They set the endgame in motion, even if a long time elapsed between the battle and the peace settlement it helped set in motion. Direct needn't mean fast. And if battles meeting one of those standards don't exhaust the field—read on to find out—last come tests of arms that settled the outcome in a particular theater of war, helping set the stage for eventual victorious peace.

So, this leaves us with a rough hierarchy of sea fights. The more fateful and enduring a battle's ramifications, the higher it stands on the list. All of which is a roundabout way of getting to my Top Five Naval Battles in World History. In order from least to most important:

5. Lepanto (1571). The Battle of Lepanto stemmed the westward spread of Ottoman power across the Mediterranean Sea. With papal sanction, the Holy League, a consortium of Catholic seafaring states, assembled a navy to engage the main Ottoman fleet in the Gulf of Corinth, off western Greece. Lepanto was the last major all-galley naval engagement in the Mediterranean. The League put its advantages in gunnery and ship types—notably the galleass, an outsized galley bearing heavy armament—to good use against the Turkish fleet, which disgorged far less weight of shot. The Ottomans lost the bulk of their vessels to enemy action. More importantly, they lost experienced crews. They found that regenerating human capital isn't as easy as fitting out wooden men-of-war. Shipwrights soon built new hulls, letting the Turkish navy reassert its supremacy in the Eastern Mediterranean for a period. By 1580, however, the new navy was left to rot at its moorings. Galley warfare assured permanent European, not Ottoman, command of the middle sea. That's a decisive result by any measure.

4. Battle of Yamen (1279). Sometimes dubbed “China’s Trafalgar,” this clash between the Mongol Yuan Dynasty and the beleaguered Southern Song determined who would rule China for nearly a century. It was far more decisive than Horatio Nelson’s masterwork. Over one thousand warships crewed by tens of thousands of men took part in the engagement. Yuan commanders deployed deception and bold tactics to overcome at least a 10:1 mismatch in numbers. Most important, Yamen claimed the life of the Song emperor, clearing the way for Kublai Khan’s dynasty to take charge of Asia's central kingdom. The results of Yamen thus reverberated throughout Asia for decades afterward.

3. Quiberon Bay (1759). The year 1759 has been called a year of miracles for Great Britain. Land and naval operations determined whether Britain or France would emerge triumphant in North America. British troops under Wolfe subdued Montcalm's defenders at Quebec and Montreal, sealing the fate of New France. France stood little chance of recouping its fortunes because Admiral Sir Edward Hawke's Royal Navy fleet ventured into Quiberon Bay that November—in a westerly gale, no less—and put paid to the French fleet in its home waters. Having wrested away command of Atlantic shipping lanes, Britain could bar access to the Americas. Lesson: to score decisive victories, hire commanders with fighting names like Wolfe and Hawke. British exploits settled the destiny of a continent while setting a pattern for North American politics that persists to this day.

2. Spanish Armada (1588). This was the duke of Medina Sidonia's purportedly invincible fleet, ordered by Spain's King Philip II to cross the Channel and land in England. There Spanish forces would unseat England's Queen Elizabeth I. By installing a friendly regime, the expeditionary force would terminate English support for the Dutch revolt roiling the Spanish Netherlands while ending English privateering against Spanish shipping. The Catholic Philip sought and obtained papal approval for the enterprise against the Protestant Elizabeth. Weather, however, conspired with English seamanship and gunnery tactics to condemn the expedition. The Spanish host was unable to land. Instead Medina Sidonia found himself compelled to circumnavigate the British Isles under foul conditions to reach home port. The failed cross-Channel crusade heartened the English crown. Had the Armada replaced a Protestant with a Catholic monarch, it's conceivable that the British Empire never would have been founded—and certainly not in the form it actually took. How would Atlantic, Pacific, and Indian Ocean history have unfolded then? The implications of that question boggle the mind—and qualify the Armada's defeat as decisive in the largest sense.

1. Salamis (480 B.C.). Taken in tandem with its immediate precursors, the sea battle of Artemisium and the land battle at Thermopylae, the Battle of Salamis was part of a joint campaign that would gladden Corbett's heart. Themistocles, the founder of the Athenian navy, led an outnumbered, outmanned allied fleet against King Xerxes' Persian armada. Artemisium kept Persian sea forces from linking up with the colossal horde that had crossed the Hellespont and was lumbering overland through Greece, with the ultimate goal of conquering Europe. Themistocles' fleet then retired to the waters off Salamis Island to defend the Athenian populace, which had abandoned its city to the Persians. Guile and artful tactics let the allies overcome Persian numbers in this narrow sea. If not for Spartan and Athenian audacity, at sea as on shore, Xerxes may have throttled Western civilization in its infancy. Fending off the Great King's onslaught entitles Salamis to enduring fame. It was the most decisive naval battle in history.

Needless to say, drawing up a list like this one is tough. Many worthy candidates ended up on the cutting-room floor. China's Ming Dynasty was born through inland naval warfare, at the Battle of Lake Poyang (1363). The Battle of the Virginia Capes (1781) doomed Lord Cornwallis' army at Yorktown and assured American independence. The naval battles at Guadalcanal (1942-1943) reversed the tide of war in the Pacific, while the Battle of the Philippine Sea (1944) doomed Japanese naval aviation—paving the way for history's last major fleet engagement, at Leyte Gulf later that year. None, however, compares to the top five for world-historic significance.

Lastly, it's fun and enlightening to speculate about the dogs that didn't bark. About, that is, the naval engagements of immense consequence that could have, and perhaps should have, yet never did take place. For instance, the U.S. Navy just celebrated the bicentennial of the Battle of Lake Erie. Despite the dismal results of the War of 1812, small-scale engagements such as Lake Erie and the Battle of New Orleans impressed the British leadership with the United States' latent military and naval strength. Trivial-seeming U.S. victories implanted the idea among British statesmen that a conciliatory policy toward Washington was more prudent than trying to outmatch a republic predestined for primacy in North America and its marine environs.

Why the rise of America didn't produce a cataclysmic naval war with the supreme sea power of the day is worth mulling over. But that, as they say, is a story for another day.

The age of the steel line-of-battleship really began in the 1880s, with the construction of a series of warships that could carry and independently aim heavy guns external to the hull.  In 1905, HMS Dreadnought brought together an array of innovations in shipbuilding, propulsion, and  gunnery to create a new kind of warship, one that could dominate all existing battleships.

Although eventually supplanted by the submarine and the aircraft carrier, the battleship took pride of place in the navies of the first half of the twentieth century. The mythology of of the battleship age often understates how active many of the ships were; both World War I and World War II saw numerous battleship engagements. These are the five most important battles of the dreadnought age.

Battle of Jutland:

In the years prior to World War I, Britain and Germany raced to outbuild each other, resulting in vast fleets of dreadnought battleships.  The British won the race, but not by so far that they could ignore the power of the German High Seas Fleet.  When war began, the Royal Navy collected most of its modern battleships into the Grand Fleet, based at Scapa Flow.

The High Seas Fleet and the Grand Fleet spared for nearly three years before the main event. In May 1916, Admiral Reinhard Scheer and Admiral John Jellicoe laid dueling traps; Scheer hoped to draw a portion of the Grand Fleet under the guns of the High Seas Fleet, while Jellicoe sought to bring the latter into the jaws of the former.  Both succeeded, to a point; British battlecruisers and fast battleships engaged the German line of battle, before the arrival of the whole of the Grand Fleet put German survival in jeopardy.

The two sides fought for most of an afternoon.  The Germans has sixteen dreadnought battleships, six pre-dreadnoughts, and five battlecruisers.  Against this, the British fielded twenty-eight dreadnoughts and nine battlecruisers. Jellicoe managed to trap the Germans on the wrong side of the Grand Fleet, but in a confused night action most of the German ships passed through the British line, and to safety.

Many, on both sides, considered Jutland a disappointment.  Both Scheer and Jellicoe believed that they missed a chance to destroy the enemy fleet, the latter with considerably more justifiable cause. Nevertheless, together the two sides lost four battlecruisers and a pre-dreadnought battleship.  Had either side enjoyed a bit less luck, the losses could have been much worse.

Battle of Mers-el-Kebir:

The surrender of France in 1940 left the disposition of the French Navy in question. Many of the heavy ships, mostly located in French colonies, could aid either Axis or British forces.  In early July 1940, Winston Churchill decided to take a risk averse approach.  The Royal Navy would force a French decision, with the result of either seizing or destroying the French navy.

The largest concentration of French ships, including four French battleships, lay at Mers-el-Kebir, in Algeria. Two of the French battleships were veterans of World War I; old, slow, and not particularly useful to either the Italian or the British navies. The prizes were six heavy destroyers, and the fast battleships Strasbourg and Dunkerque.  These ships could contribute on either side of the conflict.

The British dispatched Force H from Gibraltar, consisting of HMS Hood, HMS Valiant, HMS Resolution, the aircraft carrier HMS Ark Royal, and a flotilla of supporting ships to either intimidate or destroy the French.  Royal Navy representatives submitted an ultimatum to their French counterparts, demanding that the ships either join the British, sail to America and disarm, or scuttle themselves. What precisely happened in the communications between Force H and the French commander remains in dispute.  What we do know is that the British battleships opened fire, with devastating results. Bretagne’s magazine exploded, killing over a thousand French sailors.  Provence and Dunkerque both took hits, and promptly beached themselves.  Strasbourg made a daring dash for the exit, then outran Hood to escape the British task force.

In the end, the British sank one obsolete ship and damaged another.  They damaged one fast battleship, and let another escape.  1300 French sailors died during the battle. Fortunately, the surviving French sailors had little interest in serving the Germans; they would eventually scuttle most of their ships at Toulon, following a German invasion of Vichy.

Battle of Calabria:

Most of the battles in the Mediterranean theater in World War II came about as the result of convoy protection.  The Italians needed to escort their convoys to Libya, while the British needed to escort convoys to Malta, and points east.

In July 1940, shortly after the destruction of the French fleet at Mers-el-Kebir, the far escorts of two convoys met each other in battle.  An Italian task force consisting of the battleships Giulio Cesare, Conti di Cavour, and various smaller ships rubbed up against a British convoy including HMS Warspite, HMS Malaya, HMS Royal Sovereign, the aircraft carrier HMS Eagle, and associated escorts.

The Italians had the initial advantage, as the dispersal of Royal Navy ships meant that only Warspite could fire upon the Italian line.  Warspite engaged both enemy ships, coming under fire from Giulio Cesare as Malaya and Royal Sovereign hurried to her aid.  After several near misses on both sides, Warspite struck with one of the longest hits in the history of naval artillery.  The hit, which detonated ammunition on Giulio Cesare’s deck, resulted in a loss of speed that forced the Italian ship out of line.  This cost the Italians their moment of advantage; with odds at 3-1, the remaining Italian ships retired.

Although the Italians failed to score a victory in the battle, they did demonstrate that the Royal Navy could not operate in the central Mediterranean without heavy escort.  The addition of two new, modern fast battleships in the next months would give the Italians a major advantage, which the airstrike on Taranto would ameliorate only for a time. The Allies could not claim naval supremacy in the ‘Med’ until 1943, when the Italian fleet surrendered under the guns of Malta.

Battle of Denmark Straits:

When the German battleship Bismarck entered service in 1941, she became the largest warship in the world, displacing the Royal Navy battlecruiser HMS Hood.  In May 1941, the Bismarck sortied from Norway in the company of the heavy cruiser Prinz Eugen.  The Germans planned to use the pair as commerce raiders, with Bismarck drawing off or destroying the capital ship escorts of any convoys, while Prinz Eugen concentrated on the merchant ships themselves.

The first task force to intercept Bismarck included HMS Hood, HMS Prince of Wales, and four destroyers.  HMS Prince of Wales was theoretically comparable to Bismarck, but teething problems (she had only very recently completed trials) limited her combat effectiveness.  HMS Hood carried a similar armament to Bismarck (8 15” guns), but also carried twenty more years of age.

Appreciating the threat that long-range fire posed to the thin deck-armor of Hood, Vice Admiral Lancelot Holland sought to close the range as quickly as possible.  Unfortunately, Bismarck’s fifth salvo caught Hood amidships, resulting in a huge explosion.  Analysts debate to this day what precisely happened aboard Hood, but the blast took her to the bottom so quickly that only three crewmembers (from a crew of 1419) escaped.

Late in the battle, Prince of Wales scored a hit on Bismarck that caused a fuel leak.  This killed Bismarck’s mission; she could not raid into the Atlantic with fuel running low.  Bismarck broke contact with Prince of Wales (which by this time was severely hampered by gunnery breakdowns), and attempted to run for home.  Two days later she was caught by HMS Rodney and HMS King George V, which avenged Hood by sending Bismarck to the bottom.

Second Battle of Guadalcanal:

In late 1942, Americans owned the day over the Solomon Islands, largely by virtue of their control of Henderson Airfield.  The Japanese, on the other hand, owned the night.  The Imperial Japanese Navy (IJN) used its advantages at night to run supplies and reinforcements to Japanese troops on Guadalcanal, and to bombard American positions.

On November 13, a task force including two Japanese battleships tried to “run the slot” and bombard Henderson. The IJN task force was met by a group of American cruisers and destroyers, which took advantage of surprise and good luck to cripple the battleship Hiei.  American aircraft finished off Hiei the next day.

The following evening, the Japanese tried again. The Americans, virtually tapped out after months of grueling combat, went to their aces in the hole; USS Washington and USS South Dakota, a pair of fast battleships normally tasked with escorting carriers.  Four destroyers screened the two battleships.  The IJN force included the battleship Kirishima (sister of Hiei, and survivor of the first battle), four cruisers, and nine destroyers.

The early stages of the night action saw the IJN warships sweep aside the U.S. Navy destroyer screen.  South Dakota and Washington became separated, and the former came under heavy fire from the entire Japanese task force, which caused high casualties and a complete loss of communications.  When the Japanese opened up on South Dakota, however, they revealed their position to USS Washington, which took the opportunity to hammer HIJMS Kirishima with her 16” and 5” guns.  Kirishima suffered mortal damage, fell out of the battle line, and eventually sank (although most of her crew was rescued).  South Dakota and Washington escaped, the latter with virtually no damage.

Parting Salvos:

Only eight dreadnoughts remain, all in the United States. Over time, it is almost certain that this number will dwindle; several of the memorialized battleships are in poor condition, and likely will eventually find their way to the scrappers, or to service as an artificial reef. Nevertheless, for more than a generation analysts and the general public perceived these ships to constitute the currency of naval, and to some extent national, power.
