So now we come to the man himself, Alexander the Great. We have looked now at the army that his father, Philip, left him and established that it was well balanced, extremely well disciplined, and highly experienced. However, there have been numerous times throughout history where an excellent army has been led to disaster by a poor leader. Take the destruction of the Roman legions led by Varrus at Teutoborg for example, or the decimation of the Romans at Carrhae under Crassus. These examples show that it would be facile to claim that the Macedonian victory over the Persians was inevitable, with or without Alexander, due to the army alone. A paintbrush and canvas is only as good as the artist who utilises them, and Alexander was a true artist of warfare. This article will aim to focus on the four main areas, which in my opinion, made Alexander one of the greatest generals of all time: his ambition, his ingenuity, his bravery and his ability to read a battle.
Ambition
“My boy, you must find a kingdom big enough for your ambitions. Macedonia is too small for you.’” – Philip to Alexander

- The Macedonian Empire at the time of Philip II’s death and Alexander’s coronation
Alexander’s ambition is beyond doubt. This was a man who at just twenty years old attacked the largest empire in the known world. Greek armies had attacked the Persian Empire before, notably under the Spartan king Agesilaus II, but these invasions had been less focused on conquest, and more on liberating Greek cities on the coast and raiding for plunder and so had little lasting effect. Alexander had a bigger prize in mind. He would not be content with just taking a few territories on the Ionian coast, or even the whole of Turkey: Alexander wanted it all. This ambition is what would drive him to take an army from Greece all the way to India; even on his death bed, Alexander is said to have been planning campaigns across North Africa to Carthage and then into Italy.
Alexander’s ambition meant that his strategy did not have to revolve around simply achieving a few short term objectives, as Agesilaus II’s had, but that he could craft a much grander strategy focusing on the complete conquest of the Persian Empire. This was an aim that all Greeks could unite behind and so Alexander had no fear of losing political support at home. He was also not so short-sighted as to be content with simply defeating the Persians in battles and annexing land. He instead aspired to creating a Hellenic-Persian Empire. Throughout his campaigns, Alexander would found almost twenty cities from Egypt to the Punjab. Instead of destroying the Persian Empire, Alexander almost absorbed it. The bureaucratic system of satraps used by Persian kings was kept, as were many of the traditions. This laid the ground for a multi-cultural Hellenism that would define the near-east for centuries, and could even be seen as a forerunner of the Renaissance.

This personal drive to achieve something extraordinary was something that men could rally around and that his army could take pride in being a part of. Indeed, in his twelve years of campaigning, he suffered just two mutinies, both born more out of a desire to return home as opposed to any lack of confidence in Alexander’s abilities to achieve his objectives. If a general loses the faith of his troops, then the battle is lost before it is even fought. It is clear that Alexander’s ambition inspired his men to constantly support him against huge odds and was the driving force behind the campaign across the known world.
Ingenuity
“There is nothing impossible to him who will try” – Alexander
Throughout his campaign, Alexander would encounter many extremely difficult challenges. However, each time he was able to think of a new innovative solution in order to overcome the obstacle. Perhaps the best example of this would be the Siege of Tyre.

Tyre is a coastal city in the Levant, and with half the city situated on a small island surrounded by walls, it was known as being nigh impenetrable. This was a crucial target for Alexander to conquer and, with its excellent geographical position and formidable defences, would require all his cunning and innovation.
Put yourself in Alexander’s sandals for a moment. You stand on the coast and look out towards the island 1,000 metres away, with walls almost 50 metres tall. How do you begin to tackle it? Starving out the opponents is possible, but slow and you are in enemy territory and so would risk allowing your enemy to regroup and attack you from the mainland. Do you build a bridge in order to move ladders up to the city? Possibly, but the Tyrian navy is strong and would be sure to burn any wooden bridge that was built. You have no significant siege weapons to speak of, none at least that would be able to fire a missile so far with enough power to damage the walls. So what do you do?

Alexander, ballsy as ever, decides to bring the mainland to the city and fights the siege on his own terms. He builds a mole, or causeway, using stone taken from the mainland part of the city, approximately 60 metres wide and 1,000 metres long to reach the island. In order to counter the Tyrian archers, 50 metre towers are built at the head of the causeway, complete with ballista and catapults to provide cover. Still Alexander struggles, plagued by the Tyrian navy. Fortunately, from his previous conquests he is able to muster together a few warships from other Phoenician cities, and is gifted more by the King of Cyprus, allowing him to form a blockade of the island. Onto some of these ships, he fits battering rams to attack the walls. Every challenge that the Tyrians throw at him, Alexander finds a solution. There are huge stones under the water to stop ships approaching the wall; Alexander puts cranes on his ships and lifts them out of the water. Tyrian divers cut the anchor ropes of the Macedonian ships; Alexander replaces them with chains. In a coordinated attack from both the causeways and through a breach made by the ships, the city is taken. The siege had lasted just seven months. For comparison, Alexander’s father Philip suffered just two defeats in his career, both sieges, that lasted over a year. This level of innovation and ingeniousness is easily on par with Caesar’s circumvallation of Alesia and shows not just intelligence, but also a level of audacity that is often seen in the best military commanders.
Tyre is not the only example of Alexander’s innovativeness. As we’ve already seen, Alexander also pioneered the use of heavy shock cavalry and hammer and anvil attacks, tactics that would become staples of western warfare for centuries. Philip and Alexander were also both been innovators of siege weaponry. In fact, they had been some of the first Hellenic kings to successfully take walled cities by force, as opposed to simply starving out the inhabitants. Alexander took this one step further and seems to have been one of the first generals to use artillery on an open battlefield, instead of using them solely as tools during a siege. Whilst these tactics may seem almost banal by today’s standards, at the time they were ground-breaking and it is this kind of creativity that can really take a general from being classed as good or solid, to great.
Bravery
“Fortune favours the bold” – Pliny the Elder

The importance of bravery for a general at this time should not be underestimated. All kings and rulers were expected to be strong military leaders as well as political leaders, and so it was important that they set an example for their men by fighting alongside them. The importance of a general’s bravery, or lack thereof, is perhaps best illustrated by Alexander’s Persian counterpart, Darius III. At two key battles, Issus and Gaugamela, Darius fled the battlefield triggering a full scale rout of his army on both occasions.
Alexander was the complete antithesis of this – in every battle that he fought Alexander led from the front. When a crucial charge was needed to break the enemy line Alexander would lead it; during sieges Alexander would be scaling the walls alongside his men, constantly inspiring them by his own example. Throughout his campaigns, he would suffer a plethora of injuries that attest to his bravery and willingness to be in the very thick of the fighting. These included, but are not limited to: a sword thrust to the thigh, a ballista bolt to the shoulder, an arrow to the thigh, an arrow to the shoulder and an arrow to the lung. Alexander put himself through the same risks and dangers that he demanded of his men, and it is clear that this had a profound effect on the moral of his armies. His men consistently faced forces that vastly outnumbered their own and were not wholly routed once, always trusting that Alexander would be able to deliver victory.
An excellent example of how important Alexander’s personal bravery was to his success was during his Mallian campaign. In one siege when the army was struggling to breakthrough, Alexander scaled the wall and leaped down the other side with just two bodyguard for protection. He killed the Mallian leader but was left effectively stranded and was shot threw the lung. The army, so desperate to either save or avenge their king, launched a final frantic push, cutting their way to Alexander and winning the battle. This is an instance where Alexander’s courageousness directly led to the army’s victory, however, in almost every battle Alexander was constantly situated at the critical point. Whilst Darius is a prime example of the disastrous effect that a general fleeing can have on an army, Alexander is a prime example of how a general’s personal bravery can inspire an army and keep their morale high.
Ability to read a battle
“I do not steal victory”- Alexander
The Ancient World is full of excellent generals, Hannibal, Scipio Africanus, Casear and Pompey to name just a few, but in terms of the ability to read a battlefield, Alexander would, in my opinion, be the best. Indeed, Hannibal, the ‘father of strategy’ when asked who he considered the greatest commander named Alexander before himself.

Alexander was a fine strategist, however, as a battlefield tactician he was in his element. Alexander’s favoured tactic was to use his phalanx to pin and hold the enemy line in place with his left flank fighting a defensive action, whilst he would feint an outflanking manoeuvre with his Companions on the right, drawing the enemy cavalry away from the flank of their infantry before driving into the resulting hole, and following up with hammer and anvil attacks on the backs of the engaged enemy infantry. This is a very risky strategy. If the crucial Companion charge happens too early, then the hole in the enemy line would not be large enough and could result in the Companions, and Alexander, simply being surrounded and cut to shreds. Too late, and Alexander risked his armies left flank being overrun and his army encircled. Alexander’s timing of this charge was impeccable. Both at the battles of Issus and Gaugamela, it is this kind of charge, directly at the Persian king Darius’ position that results in Darius fleeing the battle, and the Persian defeat. This is what one means when they say that one has the ability to ‘read a battlefield’; it is being able to judge where the enemy is weak, where a charge needs to be focused, and, most importantly, getting the timing right.
The greatest testimony to Alexander’s tactical ability is the fact that he fought approximately 20 major battles or sieges and was victorious every time. Even his father Philip, excellent general though he was, was defeated twice. Out of the 10 main battles Alexander fought, 4 were opposed river crossings and 2 were in defended narrow mountain passes. These are very difficult terrains for an attacking army, especially one relying on heavy cavalry and phalanxes, both of which excel in open terrain. Alexander’s success in such circumstances is again testimony to his extraordinary tactical ability.
Conclusion
“A tomb now suffices him for whom the world was not enough” – Alexander’s tombstone
It has become almost clichéd to say that Alexander was a great general, however, it is not a cliché without any evidence, nor one that becomes any less true upon repetition. Alexander was gifted the greatest military machine of its time in the form of the Macedonian army. However, it was not an invincible force; Philip had been defeated whilst in command of the force and future kingdoms that used the same army composition would not be able to replicate Alexander’s achievements.
Alexander was one of these rare figures in history who is truly unique in his time. Philip could not have done what Alexander did, nor could any of Alexander’s lieutenants. The Macedonian Empire and the success of the army was built by Alexander himself. The clearest evidence for this is that just one year after Alexander’s death, his empire would fracture into several smaller warring kingdoms led by his lieutenants. Without Alexander’s personal leadership, without his ambition, without his extraordinary military mind, these Hellenic kingdoms would never again reach the astounding heights they had under Alexander the Great.
