Chapter 1: What was Hannibal's strategy after the Battle of Cannae?

10.797 - 34.29 Dominic Sandbrook

On the battlefield of Cannae, the victorious Hannibal was surrounded by his officers. They were all congratulating him and urging him to take things easy for the rest of the day and the night and to allow his exhausted troops to do the same. But Mahabal, his captain of horse, had a very different take on the situation, for he was convinced that not a moment was to be lost.

34.574 - 57.794 Dominic Sandbrook

My lord, he declared, if you wish to understand properly what you have secured with this victory, then let me tell you that within five days you will be feasting in triumph on the capital in Rome. I will go ahead with my horsemen. The first the Romans will know of the fate about to overwhelm them will be the sight of our cavalry at the gates of their city.

0

58.655 - 82.402 Dominic Sandbrook

All you have to do is to follow where we lead." But to Hannibal, this seemed altogether too optimistic, too ambitious a plan. While I commend your spirit, he said to Mahabal, I need time to evaluate what you are suggesting. To which Mahabal retorted, Gifts are never lavished by the gods in their entirety on a single man.

82.903 - 108.118 Dominic Sandbrook

You know, Hannibal, how to win a battle, but you do not know how to use your victory. So, a very celebrated moment in ancient history. This is the aftermath of the most notorious, the most shattering defeat ever suffered by a Roman army. And this is being reported two centuries later by the historian Livy.

0

108.098 - 125.01 Dominic Sandbrook

So to give people a little bit of context, the battle in question was the Battle of Cannae. It was fought on the 2nd of August, 216 BC, and it resulted in the almost total annihilation of the largest army that the Roman Republic had ever put into the field.

125.159 - 144.535 Dominic Sandbrook

And last year, Tom, in our episode on the Battle of Cannae, episode 571, for people who are interested in that kind of thing, you came up with some extraordinary facts to illustrate just how industrial the slaughter at Cannae was. So the Romans suffered more casualties at Cannae, if the ancient historians are to be believed.

144.515 - 155.876 Dominic Sandbrook

than the British army had suffered on the first day of the Somme, or the Americans had suffered in the entire Vietnam War. The stakes in this war between Rome and Carthage are that high.

156.116 - 178.293 Tom Holland

Absolutely. And if Cannae is the worst defeat in Rome's history, it is the greatest victory ever won by their enemies. the Carthaginians led by their great general Hannibal, still only just 30 when he won that victory. And it's the apogee of Hannibal's career.

178.333 - 208.525 Tom Holland

It's also in a sense, the apogee of Carthaginian power, because from this point onwards, it's going to be downhill for Carthage and indeed for Hannibal. And it will culminate in in 146 bc so you know not many decades later in the complete annihilation of carthage and we're going to be telling the story of how we go from can i to the complete destruction of the city in the next four episodes

Chapter 2: How did the Romans respond to their defeat at Cannae?

388.053 - 389.695 Dominic Sandbrook

Remind us how the Romans did it.

0

389.675 - 414.547 Tom Holland

Well, the Romans have immense reserves of manpower. So they are now the dominant power in Italy. And they have essentially constructed this framework of alliances. Defeated cities are offered various degrees of citizenship or associated status. And essentially, loyalty on the part of defeated cities to Rome is very amply rewarded. They get given chunks of spoil or whatever.

0

414.808 - 442.682 Tom Holland

Also, the Romans have an incredibly dogged system. in fact, implacable resolve never to accept defeat, never even to accept disrespect. It's almost a kind of mafia attitude. The classic example of how far they are prepared to go in the search of victory is the fact that even though they are the elephant to Carthage's wail, over the course of the First Punic War, as it comes to be called,

0

442.662 - 465.446 Tom Holland

They transform themselves into a naval power. I mean, they do it in a slightly makeshift way. They find a galley and it's kind of, it's like a kind of Ikea flat pack. And this is how they build their fleet, but they just go on and on and on. And by the end of it, they've won. And the treaty that they force on Carthage in 241 BC essentially institutionalizes Roman control of Sicily.

0

465.726 - 488.095 Tom Holland

And this is a key moment in the emergence of what will become the Roman empire. Because a large swathe of the island, about three quarters of it, comes under the authority, in Latin, the provincia of a Roman governor. And this word provincia is the word from which the English word province will ultimately derive.

488.175 - 496.767 Tom Holland

So in effect, kind of the three quarters of Sicily that the Romans have seized becomes Rome's first overseas province.

496.747 - 511.929 Dominic Sandbrook

And this treaty, so we're in 241 BC. The Carthaginians, this great naval power in the Western Mediterranean, have been defeated unexpectedly. They've signed this treaty, agreed this treaty with the Romans. And this treaty, you could liken it, I suppose, to the Treaty of Versailles or something.

512.13 - 528.745 Dominic Sandbrook

Because it's often said, when people are talking about the origins of the Second World War, that they were kind of implicit in the way the First World War ended. Because the very punitive treaty that the Allies forced on the Germans meant that the Germans were bound to seek revenge or redress at some point.

528.927 - 534.454 Dominic Sandbrook

And do you think this is true of Carthage as well, that basically the First Punic War means there's bound to be a second one?

Chapter 3: What role did Carthage play in the Mediterranean before the Punic Wars?

708.306 - 733.298 Tom Holland

Hamilcar, in the wake of Carthage's defeat, decides that there is a need to find a replacement for Sicily, a new base for empire. He fixes on Spain and he builds a very substantial empire there. And he dies there fighting against Spanish Iberian warriors, but he has three sons to succeed him. And the eldest of these is Hannibal, the famous general who will win the Battle of Cannae.

0

733.638 - 749.217 Tom Holland

The two other sons, Hasdrubal and Mago, and they will also feature in the war that Hannibal launches against Rome. Because Hamilcar dies in battle in 229, and Hannibal proves a very, very worthy heir to his father.

0

749.197 - 764.708 Tom Holland

And by the 220s BC, he's built on the foundations laid by his father, and he has fashioned Spain into a very formidable launchpad for attacking Rome and for launching what he obviously sees as a kind of war of vengeance.

0

764.688 - 774.31 Dominic Sandbrook

Well, he has a new Carthage, doesn't he? Because they've got this dazzling new capital with harbours and city walls and fortifications and so on. He didn't build it himself, but he's inherited it.

0

774.731 - 796.767 Tom Holland

Yes. And so it's called Carthage, but the Romans will call it New Carthage. And I think it's easier for us to follow the Roman example. And as you say, it is modelled on the original Carthage and it is impressive in the way that the original Carthage is. And people may be wondering, well, how can this be afforded? Well, it can be afforded because Spain is massively rich in mineral wealth.

797.328 - 814.332 Tom Holland

There is gold, there is silver, there is copper, there is tin, there is lead. There's basically everything that you could possibly want. And the gold and silver in particular can be used to recruit mercenaries. So infantry from Spain, the Spaniards are very proficient fighters.

815.714 - 840.587 Tom Holland

Infantry from Libya, cavalry from Numidia, which is basically now Algeria, which is by far the best light cavalry in the world. And Hannibal by 218 is ready to take the Romans on. And very famously, he does this by taking the land route from Spain to Italy, complete with elephants, and he crosses the Alps. And this is probably the one thing that everyone knows about Hannibal.

841.207 - 863.753 Tom Holland

And he has with him his youngest brother, Mago. He leaves Hasdrubal, his younger brother, to garrison Spain. And he also takes with him someone we've met in the reading that you gave at the start of this program, Mahabal, who is probably Hannibal's nephew. And these are all very battle-hardened, seasoned, able men.

864.113 - 876.938 Dominic Sandbrook

And then the result of this, so he crosses the Alps, famously, elephants in tow, and he comes down into the plains of Italy, and he has a hat trick on. of extraordinary victories.

Chapter 4: What were the consequences of the First Punic War for Carthage?

1205.391 - 1218.072 Tom Holland

So not everyone in the Roman task force that had been defeated at Cannae had actually died. Some, a few, had managed to break out through the Carthaginian lines as they kind of pressed in on the captured Romans.

0

1218.052 - 1239.418 Tom Holland

And also there were something like 10,000 men who had been left as a reserve in the main Roman camp, which was on the other side of a river from the plain where the battle had been fought. And the fugitives from Cannae, some of them had sought refuge in the town of Cannae itself, near the battlefield, of course.

0

1239.398 - 1258.032 Tom Holland

And others had sought refuge in a second, smaller camp that had been built in the rear of the Roman battle lines. So people should imagine that there's the plain where the battle is fought. There's this smaller camp where the Roman generals and people had been based before the thing. Then there's a river. And on the other side, there is a massive Roman military camp.

0

1258.012 - 1281.456 Tom Holland

There are 10,000 men in the large camp. There are refugees in the smaller camp. They're separated by this river. So Hannibal in the morning turns his attentions to the Romans who've taken refuge in the town of Cannae and in this smaller fort. The fugitives in Cannae are very quickly taken prisoner. Then Hannibal is preparing to move on this small Roman camp, which is of course fortified.

0

1281.476 - 1301.105 Tom Holland

I mean, the Romans there can hope to hold out. And officers in the main Roman camp, so on the other side of the river, they've been urging the fugitives to, you know, don't stay there. You're going to be, you know, you're going to be wiped out if you do stay there. Cross the river, come and join us. You can add to our numbers and hopefully we can kind of get away from here.

1301.465 - 1329.75 Tom Holland

But the Romans fugitives are so demoralized that ultimately only about 600 make the attempt and managed to get away across the river. And so they and the 10,000 reserves had then managed to march out of the main camp to avoid being cornered by Hannibal's cavalry. And they cross the plain and they reach a walled town called Canusium, which is about six miles from the battlefield.

1329.73 - 1353.118 Tom Holland

So the fact that so few people had wanted to take the risk and escape from that smaller camp to join the large camp, I mean, this to Hannibal is an indicator that Roman morale is broken. But also what then happens in Canusium is another indicator of this. Because even in the relative safety of Canusium, which is a walled town, it's evident that morale is really, really at rock bottom.

1353.839 - 1380.828 Tom Holland

So one officer... who is the son of a consul, the consul is the kind of the leading magistrate in the Republic, he is reported by Hannibal's spies to have insisted publicly that all is lost, to quote him, the future has nothing to offer but misery and despair. And there are other officers who, again, are men of very high birth, high rank, who are said to be planning to flee overseas.

1381.228 - 1383.43 Tom Holland

You know, they have despaired of the situation.

Chapter 5: How did Hannibal prepare for his campaign against Rome?

1748.206 - 1767.073 Tom Holland

Yeah. So Fabius has obviously sent scouts out along the roads. They say, no, nobody's coming from Cannae. This kind of potential mutiny in Canusium with all the officers who are kind of panicking and wanting to go abroad. This is put down by a young officer, no more than 19 years old at this point. And he is called Publius Cornelius Scipio.

0

1767.534 - 1788.987 Tom Holland

And he's the son of the consul who had confronted Hannibal in the year of his invasion of Italy. And he had drawn his sword, pointed it at his jittery fellow officers and made them swear an oath. And I quote, never to desert our country nor permit any other citizen of Rome to leave her in the lurch. So, you know, morale is restored in Canusium. And

0

1788.967 - 1809.945 Tom Holland

Even the arrival in Rome of one of the two consuls who had been defeated at Cannae, which you might think would just plunge people into despondency. Actually, it serves to boost spirits in the city. And this consul who arrives is a guy called Terentius Varro. And he, unlike his colleague who had fallen in the battle, he'd managed to escape the slaughter.

0

1809.925 - 1830.567 Tom Holland

He ends up going to Canusium, taking charge of the soldiers there. He works hard to get them into fighting order, and then he hands them over to the command of the man who has been sent by the Senate to replace him. For Varro, the prospect of going back to Rome is obviously a terrible one. He's presided over the worst defeat in Rome's history.

0

1830.547 - 1856.656 Tom Holland

He does go back and he's braced to accept whatever punishment the Senate might decree. But the Senate is impressed by his courage in returning to face the music. And so instead, it gives him a vote of thanks. And the reason for this vote of thanks, he had not despaired of the republic. And so this notion that to despair is the worst of crimes is absolutely enshrined.

1856.836 - 1861.204 Tom Holland

This is the great message that the Romans are proclaiming to the world.

1861.685 - 1879.306 Dominic Sandbrook

And not only that, but the Romans, so when these prisoners arrive, so these prisoners who've been sent by Hannibal, basically to ask for a ransom and to start the process of negotiations when they turn up outside the city. The Romans don't even let them in, do they? I mean, that's a very, very bold statement of intent.

1879.326 - 1883.537 Dominic Sandbrook

We're not even going to consider talking to you because we're so determined that we fight on.

1883.517 - 1903.934 Tom Holland

It's a massively hardcore decision, because what it means is that the Romans are losing fit men of military age that they might have ransomed, and they're very short of fit military men. Individual senators, of course, they would have relatives there. They might have sons or brothers or whatever. And sure enough, when the news comes back to Hannibal, he's furious.

Chapter 6: What was the significance of Syracuse in the Punic Wars?

2126.49 - 2147.65 Tom Holland

There is this famous cry, Hannibal ad portas, Hannibal at the gates, which becomes one of the most famous phrases in Roman life and culture. But the Senate. unlike the mass of the populace, refuse to panic because they know the situation. As you said, Hannibal doesn't have siege equipment. There's no prospect that he'll be able to storm the walls.

0

2148.111 - 2164.079 Tom Holland

And what is more, by great good fortune, it so happens that two legions are present in Rome at the time when Hannibal appears before the walls. And that's about 10,000 men. So there is actually, in the upper echelons of the Roman elite, they're not panicking.

0

2164.439 - 2185.06 Tom Holland

And in fact, there is a famous story, which regrettably is very late, and so therefore it's probably made up, but it's a good one anyway, that even as Hannibal is camped out on the estates and lands beyond Rome, the Senate are auctioning off the land on which he's camped, and that there are lots of buyers for it. So a nice statement of Roman pluck.

0

2185.546 - 2209.917 Tom Holland

And their sang-froid is entirely justified because in due course, Hannibal abandons his camp. He leaves Rome. He's off roaming across Italy again. The city has survived. And what is more, his diversionary tactic doesn't prove successful because shortly after he's marched on Rome, Capua submits and he loses essentially what had been his capital.

0

2209.897 - 2238.52 Tom Holland

Now, this doesn't really bring Rome any closer to ultimate success because Hannibal is still undefeated. The Romans are still reluctant to meet him in battle. And lots of other cities, lots of other peoples and regions do remain loyal to Hannibal. And so the problem essentially for both sides now, Hannibal and the Romans, is that neither side really seems to have a route to defeating the other.

2239.175 - 2250.89 Tom Holland

But I guess for the Romans, I mean, bearing in mind the scale of the disaster they had suffered at Cannae, I mean, a stalemate is a kind of victory for Rome.

2251.291 - 2276.68 Dominic Sandbrook

Yeah, but the stalemate will not last because both sides are determined to break it. Certainly the Romans are. And after the break, we will find out how this extraordinary war, this duel between Hannibal and Rome takes another twist. Welcome back to The Rest is History. The great war between Hannibal and the Romans has degenerated into a stalemate.

2276.74 - 2301.114 Dominic Sandbrook

Hannibal's won his battle at Cannae, but he hasn't pressed home his advantage. He hasn't captured Rome. On the other hand, the Romans don't want to face him in battle because they know that he is... A formidable opponent. So the question is, how are the Romans, or indeed the Carthaginians, going to break the stalemate? And the answer lies not in Rome specifically, but in Italy, doesn't it?

2301.174 - 2304.602 Dominic Sandbrook

It's the mastery of Italy that is now the bone of contention.

Chapter 7: What innovative military strategies did Archimedes employ?

2566.076 - 2583.478 Tom Holland

And again, all of these have been comprehensively renovated and refurbished. It has impregnable walls, which stretch 17 miles. And a lot of these walls are snaking up and over mountainous heights. So essentially, it's almost impossible for a besieger to invest the city.

0

2583.458 - 2602.669 Tom Holland

It has an enormous fortress, the Euryalus, which is set on the highest point of the city walls and dominates the land approaches to Syracuse. And even the very oldest part of the city, which is an island called Ortigia, so just off the mainland. This is where the first colonists from Corinth had settled, who founded Carthage.

0

2603.129 - 2609.179 Tom Holland

This now boasts a really sumptuous, magnificent palace, a palace that can rival the palace in Alexandria.

0

2609.159 - 2629.648 Dominic Sandbrook

And the bloke who has paid for all this, or has commissioned it, the bloke who's been running Syracuse for the last few decades, is this guy who used to be, he's a hard man, isn't he? He's an ex-captain of mercenaries called Hieron. And he's incredibly old, especially by classical standards. He's almost 90 now.

0

2629.628 - 2657.723 Tom Holland

Well, yes. So by the time that Hannibal launches his invasion of Italy, Huron is in his late 80s. And he has been in charge of the city since the 270s. So, I mean, that is a very, very long period of office. And it reflects the fact that he is a very, very wily, astute man who is able to capitalize on two tremendous advantages. And the first of these is the alliance with Rome.

2658.044 - 2679.298 Tom Holland

It's Hieron who kind of says, we are sticking to Rome through thick and thin. Although he was a mercenary, and although it's kind of, you know, for centuries been the national sport of the Greeks in Sicily to fight each other, Hieron actually isn't a great man for war. He's a man of peace. And the Roman alliance enables him to enjoy decades of peace.

2679.879 - 2700.517 Tom Holland

And so the money that previous leaders of Syracuse would have squandered on pointless wars, with Carthage or with other Greek cities or whatever, Heron is able to spend this wealth on beautifying Syracuse and on growing the economy. So, you know, by expanding the harbours or whatever, he makes Syracuse richer and more productive.

2700.858 - 2722.258 Tom Holland

And even the defeats of Rome at first late Trasimene and then Cannae cannot persuade him to budge in his loyalty to Rome. So in the wake of Cannae, he sends the Romans grain, he sends them troops, he sends them financial subsidies. The special relationship holds rock solid. So that's the first advantage that Hieron feels he has.

2722.238 - 2749.242 Tom Holland

There is another advantage, and that is the fact that he has in Syracuse one of the great geniuses of history. And this is a man called Archimedes. And Dominic, I know you love a mathematician and an engineer, don't you? And Archimedes is... I mean, he's kind of hailed by Leonardo, by Galileo, by Newton as the greatest, the goat.

Chapter 8: How did the fall of Syracuse impact the outcome of the war?

2964.665 - 2992.035 Tom Holland

In 215, everything changes because Hieron dies. And by this point, he is 92 years old. And he's succeeded by his grandson, who's a guy called Hieronymus. And he is still only a teenager. He's very headstrong. He's very inexperienced. And he fatally is persuaded by an anti-Roman faction in the city that Rome is doomed and that he should open negotiations with Carthage. Ooh, that's a big twist.

0

2992.395 - 3015.664 Tom Holland

It's in the wake of Cannae. You can see why they would do it. But the pro-Roman faction, which is very strong in Syracuse, they immediately have Hieronymus assassinated and there's a low-level civil war. A republic is proclaimed. The pro-Carthage faction triumphs and it opens negotiations with Hannibal and it starts to launch raids on Roman-held territory in Sicily.

0

3015.644 - 3034.918 Tom Holland

And this, Dominic, proves to be, for Syracuse, an absolutely calamitous mistake. Hieron had been right. It is the worst policy imaginable to take on the Romans, even as they are kind of battered by all the losses of manpower that they've been suffering at the hands of Hannibal.

0

3035.084 - 3050.17 Dominic Sandbrook

Not least because the Roman, the top Roman in Sicily, who's called Claudius Marcellus, he is a very formidable person, isn't he? He had killed a king of the Gauls in single combat and had won the Spolia, what's that?

0

3050.351 - 3073.222 Tom Holland

Spolia Apima, which is the greatest prize that any Roman could hope to have. So you kill your enemy general in combat and you strip him of his armor. And it's just tremendous glory. And this is what Marcellus has done. He's been consul for five times. He's quite a cultured man. He's a lover of Greek culture. He will prove to be a great admirer of Archimedes.

3073.523 - 3096.866 Tom Holland

But he's absolutely not someone to mess with. So he's described in a later biography as a man of war with a body hewn from granite and a sword arm of devastating power. And this is the guy in the spring of 213 who appears before the walls of Syracuse at the head of a large army of Romans, many of whom are veterans of Cannae.

3097.106 - 3118.278 Tom Holland

So those 10,000 who had survived Cannae and who are therefore desperate for revenge. They camp out before the walls of Syracuse. And on the seaside, Marcellus gets on board his galley and leads a battle fleet into the harbors of the city. So it's a kind of pincer movement. And the Syracusans understandably are terrified.

3118.899 - 3124.626 Tom Holland

But this is the moment when Archimedes and his war machines come into their own.

3124.606 - 3135.116 Dominic Sandbrook

Bring out the scorpions. Bring out the scorpions. Bring out the catapults. And the scorpions and the catapults are incredibly effective, right? They absolutely bombard the Roman besiegers.
