TRIREME FIGHTING IN THE AEGEAN (411–405) II

Battle of Cynossema, 411 BCE. Athenian fleet in blue, Spartan navy in red.

Bloodbath

Yet if the Aegean had been relatively quiet since 429, suddenly from 411 to 404 the Athenians met the Spartans and their allies in at least seven major engagements. Across time and space, rarely are rival fleets willing to engage each other repeatedly until one side is not merely defeated but annihilated. Such is the conservatism of admirals who so jealously protect their precious assets while on the high seas. Like the British systematic destruction of the Napoleonic armada or the American Seventh Fleet’s brutal death struggle with the Japanese, which finally ended with the utter annihilation of the most lethal carrier and battleship force of the pre–World War II world, both Athens and Sparta now no longer sought mere tactical advantage but were willing to risk their all to finish off the enemy.

To win, Sparta had to kill off, capture, or scatter a final cohort of at least another 50,000 or so Athenian and allied sailors and sink another 200 ships, which otherwise, over a decade, might replace the losses of Sicily. These last battles across the Aegean—they are often lumped together and called the Ionian War—were decided in the waters off western Asia Minor (Ionia) and in or near the Hellespont (the modern Dardanelles). If Boeotia, home of nine major hoplite battlefields by the fourth century, was once dubbed by the Theban general Epaminondas “the dancing floor of war,” one could call the Hellespont and the adjoining Propontis (the Sea of Marmara) “the seas of death.” In those environs alone 50,000 men were probably killed, missing, or captured in just three battles at Cynossema, Cyzicus, and Aegospotami, all within a sixty-mile radius. In addition, between 412 and 404 thousands more Athenians, Persians, and Peloponnesians died in ambushes, seaborne attacks, and random killing up and down the Ionian seaboard.

With the establishment of a permanent garrison at Decelea, the new Peloponnesian fleet was confident that it now had muscle enough to block grain ships from arriving at Attica. Thus, this time under a year-round combined land and sea assault, the city, it was thought, would shortly go bankrupt if not starve: keep Attic farmers away from their land, destroy ships that imported food, deny access to grain-growing areas abroad, assure subjects that they can revolt in safety and withhold tribute, and all the while sink Athenian triremes. Decelea was the antithesis of Archidamus’ earlier failed strategy, which had offered no permanent presence and no ancillary naval strategy.

Not long after the defeat in the Great Harbor of Syracuse, an emboldened and reconstituted Spartan armada engaged what was left of the Athenian fleet in a series of inconclusive sea battles in the Aegean, at Spiraeum (412), Syme (411), Chios (411), and Eretria (411). Whereas losses at these rather obscure sea battles on both sides were minimal, the succession of collisions began to wear on a shaky Athens and had the practical effect of destroying another 30 or so Athenian triremes.

More importantly, perhaps 5,000 seamen were killed, scattered, or captured. Despite spending its final 1,000-talent critical reserve on rebuilding the fleet, strategically Athens could no longer control even the seas off its own coast. It was also on the verge of losing much of Ionia and, with it, a tribute-rich empire. After the defeat at Eretria in nearby Euboea—the Athenians lost 22 ships and most of the crews were killed in battle or captured—a panic descended upon the city that was greater than the near riot that had broken out after the news of the Sicilian disaster reached the Piraeus, two years earlier.

The final phases of the war next turned to the northern coast of the Hellespont. There, near the peninsula called the Thracian Chersonese, the Spartans now tightened the noose, hoping to cut off the sea-lanes between Propontis and Athens. In summer 411 at Cynossema, 76 Athenian ships, under the brilliant general Thrasybulus, beat back the larger Peloponnesian fleet of 86 triremes. Perhaps 32,000 seamen were involved. At least 36 ships were lost in fighting that spanned some eleven miles of the strait. The total casualties are unknown—though as many as 7,000 may have been killed, scattered, or wounded. The Athenians claimed victory on the basis that they had at least kept their last fleet intact. They had regained morale in their first major fight after the disaster in Sicily, defeated a fleet that included several hated Syracusan triremes last encountered in the disaster of the Great Harbor, and ensured that commerce with Athens remained open. As Thucydides rightly put it, “They stopped considering that their enemies were worth much in naval matters.”

Yet in such battles of attrition, the greater resources now were starting to tip toward the Peloponnesians. Their newfound pluck at sea would encourage more contributions from their allies and closely observant Persia. In contrast, to win the war on the seas the Athenians would have to inflict crushing losses on the Spartans while losing almost none of their now precious triremes. Thucydides, for example, said of the Athenian victory at Cynossema (fought not far from Gallipoli) that it came “at just the right time,” inasmuch as small losses to the Peloponnesians in the prior two years and the great catastrophe on Sicily had made them “afraid of the Peloponnesian fleet.”

To compound the Peloponnesian misery, not far away, at Abydos, a few weeks later the Spartans once again forced battle. There they were to lose another 30 ships, along with thousands of crewmen. Still, Alcibiades—in 411 he had returned to Athens in yet another incarnation, as chief Athenian admiral—summed up the Athenian dilemma best before the battle of Cyzicus. After explaining why his crews had “to fight at sea, fight on land, and fight against walled fortresses,” he finished with the admission of a bitter reality: “The reason is that there is no money among us, while the enemy has all they wish from the king of Persia.”

Sparta was not to be deterred by the loss at Abydos in its ambitious efforts to destroy what was left of the once grand Athenian fleet. In between battle and revolution, the Spartans offered Persian bonuses for oarsmen on the open market, rightly figuring that higher pay in the Peloponnesian navy would cause desertion from the Athenian fleet, which now depended on mercenary rowers.

About six months later, in March 410 and thirty-five miles distant from Cynossema, the Spartan fleet unabashedly forced battle again, near Cyzicus. In this third consecutive battle of the Ionian War, after Cynossema and Abydos, the Peloponnesians suffered yet another setback, despite their now accustomed numerical superiority. Inspired leadership by the veteran generals Thrasybulus and Alcibiades and remarkable seamanship by a new generation of Athenian oarsmen, who went to sea in a storm and performed flawlessly the difficult periplous, explain the remarkable victory. In fact, Cyzicus proved one of the greatest naval disasters for any Greek fleet during the entire war. Yet it was the beginning, not the end, of the bloodbath in the Aegean.

Another 60 ships, including 20 Syracusan triremes, were now lost, some of which their dejected crews burned after seeing the defeat of their allies. The casualties are not known, but they must have been high. Perhaps well over 10,000 seamen were captured, scattered, or killed, including the Spartan general Mindarus. The historian Xenophon, in one of the most famous passages in his Hellenic history, quotes a laconic letter sent back home to Sparta from the surviving vice admiral Hippocrates—intercepted by the victorious Athenians—that read: “The ships are gone. Mindarus is dead. The men are starving. We are at a loss what we should do.”

What to do? In less than a year, Sparta had suffered staggering losses. Somewhere between 130 and 160 triremes were gone—almost the entire contribution two years earlier of its Peloponnesian and Syracusan allies. How many were dead, wounded, or lost is not recorded. In theory, between 20,000 and 30,000 seamen were on those ships that went down; in reality, no doubt at least a few thousand probably escaped or were captured.

Suddenly the entire course of the war began to change. After Sicily, the Greeks had assumed that Athens was finished. Now they were not so sure. Athens’ food supply was still safe. Rebellion among the allies was less likely. Athenian naval prestige was once again unquestioned. And most importantly, generals like Thrasybulus, Theramenes, and Alcibiades had proved that they were far better tacticians than almost all the admirals that had accompanied the Spartans to the Aegean.

After Cyzicus, a dejected Sparta apparently remembered why it had not sought naval engagements against Athens some twenty years earlier. In frustration, Sparta quickly sent out peace feelers to Athens: “We want to have peace with you, men of Athens,” their ambassadors pleaded in offering a return to the prewar status quo. But the Athenian assembly, perhaps led by rabble-rousing demagogues like Cleophon, was now aroused, drunk on success and paranoid after the failed oligarchic coup of 411. For the first time in some three years, the Athenians had thoughts of reclaiming the entire Aegean. Maybe they really could destroy the Spartan fleet for good, and drive the Persians out of Greek affairs. Unsure how to follow up their spectacular successes, the Athenians unwisely played defense for nearly four years, between 410 and 407, while the Spartans rebuilt their forces and found themselves a true military genius in Lysander, albeit one who did not emerge in a major role until 407, near the end of the war.

Unfortunately for the Athenians, few of the city’s politicians saw the true complexion of this new Ionian War, and ignored the advice of the three brilliant generals, Alcibiades, Thrasybulus, and Theramenes, who had brought them such stunning victories. The truth was that the war had now changed dramatically and could no longer be seen in terms of the old simple Spartan land/Athenian sea dichotomy of decades past. The newfound Spartan ability to tap into the imperial treasuries of Persia, through the direct succor of its western satrapies, ensured the enemies of Athens an inexhaustible supply of mercenaries, new triremes, and money to hire crews who were experienced rowers, not rustic farmers from the Peloponnese.

To nullify the Spartan advantage in numbers and its determination to prompt battle repeatedly, Athens had to rely on superior seamanship and command in every major battle, without any margin of error. It could not fight on the defensive, since it was trying to maintain an empire, which involved more than just keeping out the Spartan fleet. And an unforeseen result of the Athenian victory at Cyzicus was a reexamination of the Spartan command, leading to the appointment of a new admiral, Lysander, who, even more so than Brasidas, would prove to be the unqualified military genius of the entire war on either side, the most ruthless, brilliant, and multidimensional battle leader Greece had produced since Themistocles. Most Spartan generals were fighters (with tough names like Thorax, “Breastplate,” and Leon, “Lion”), but rarely was one both heroic and full of strategic insight about how to defeat something as insidious as the Athenian empire. The presence of Lysander—a man cut from the same cloth as Brasidas and Gylippus (none of them were Spartan royalty and thus all were considered somewhat expendable)—along with a greater infusion of Persian capital was felt almost immediately as the Spartan maverick systematically hunted down grain ships, stormed Athenian strongholds, and enslaved captured peoples. In the next major battle, at Notium (spring 406)—the Spartans had used the three-year hiatus in naval confrontation to rebuild their fleet—Alcibiades temporarily left command to Antiochus, a minor captain, with strict orders to avoid an engagement in his absence.

Instead, the Athenians rashly fought Lysander off Ephesus, and right away lost 22 irreplaceable ships. By any measure this was small potatoes after the stunning string of victories at Cynossema, Abydos, and Cyzicus. On the other hand, every Athenian trireme was now precious. Despite the fact that when Alcibiades returned to Notium after the defeat of his subordinate the Athenians still had as many ships as Lysander, the loss caused outrage at a desperate Athens, raising the specter of Alcibiades’ past machinations and triangulations.

Once more Alcibiades was banished, and with that Athens lost its most capable and popular admiral. True, Athens had lost few ships, and its fleet of 108 remaining triremes was roughly the same size as the Peloponnesian armada. But Athens’ dilemma was not merely that it had to stop the Persian fleet but that it had an empire to protect in Ionia as well, a fact that in strategic terms meant that superiority, not parity, in ships was required.

A few months later at Mytilene, the Athenians under Conon lost another 30 ships to a Spartan fleet that once more had grown to somewhere between 140 and 170 ships. In response, the Athenians began a desperate search for even more manpower, putting old and young, slave and free, poor and wealthy on triremes in hopes of manning enough ships to thwart the Spartan juggernaut. By late spring of the same year, the death struggle continued as the fleets once more sailed to engage each other off the Ionian coast. In the previous five years, at the smaller battles of Spiraeum, Syme, Chios, Eretria, and Abydos and the three great fights at Cynossema, Cyzicus, and Notium, at least 84 Athenian triremes had been lost, along with perhaps as many as 16,000 seamen. Sparta, in turn, had suffered nearly double those casualties—160 ships sunk or captured and, with them, perhaps as many as 30,000 sailors.
