While popular history tends to bring forth the notion of Alexander the Great as a military genius (and rightly so), his generalship was not only mirrored by his individual brilliance but also the impressive efforts of his army. To that end, in many ways, the destiny and legacy of Alexander was rather forged by the military prowess and organizational capacity of his commanded Macedonians. So, without further ado, let us take a gander at ten things you should know about the mighty ancient Macedonian army of Alexander the Great.
1) Dangers Forge the Macedonian Army of Philip –
When Philip II of Macedon (or Phílippos II ho Makedon – Alexander’s father) ascended the throne of Macedon, his realm was beset on the northern side by the ravaging Illyrians and precariously poised on the southern borders with the opportunistic Greeks. To make matters worse, the Macedonian army was all but vanquished – with their earlier king and many of the hetairoi (king’s companions) meeting their gruesome deaths in a battle against the invading northern tribes. But as the saying goes – “necessity is the mother of all inventions”; Philp went on to initiate a military reform of sorts that focused on training and equipping the infantry levies of Macedon, many of whom came from semi-nomadic shepherding backgrounds (as opposed to the Greek farmer/hoplite tied to his land).
Partly inspired by the great general Epaminondas and his Theban army, and also influenced by the contemporary Athenian general Iphicrates, Philip adopted the nascent ideas of the phalanx, wherein the infantrymen, in their deep formations, were armed with heavy, lengthy spears but armored in light attires. This ‘anvil’ of solid bodies of infantry was complemented by the ‘hammer’ of elite cavalrymen – Philip’s new ‘companions’ comprising various Greek nobles settled on the fiefs taken away from previous enemies. These corps of mounted warriors were presented with heavy cuirasses and Phyrgian helmets, and they acted as a hard-hitting yet mobile force on the battlefield.
2) The Personal Companions and Royal Pages –
Now it should be noted that hetairoi as a term is pretty vague, and it could denote both the aforementioned ‘companion’ cavalry and the king’s own personal companions. The latter group possibly pertained to the courtiers of ancient Macedon, who traveled with the basileus (king) and convened with him in the royal tent. Ancient sources also mention the term philoi (friends), which could have probably denoted the personal companions who held the highest positions in the hierarchy of the court. Interestingly enough, Alexander also preferred his dedicated ‘department’ of chaplains. These men, often accompanying the marching Macedonian army, had the important duty of convincing the soldiery of favorable battle omens by a mix of showmanship and augury.
Beyond the hierarchy of personal companions, Alexander also approved of a more centralized control on the nobles of the Macedonian society. A nifty solution came forth in the form of the Royal Pages (Basilikoi Paides). These group comprised the sons of nobles who were incorporated into the aristocratic court, albeit as servants of the kings. Fulfilling a role similar to the medieval squires, these teenager males were basically taken up as hostages who would serve as ‘guarantees’ of their parent’s loyalties.
Beneath this political veneer, the Royal Pages also performed a practical function. As the noble youth of the burgeoning realm, they were indoctrinated and inducted into the loyalty-based cult of the king. At the same time, they were trained within the scope of the royal machinery, ranging from menials tasks (including pouring the king’s bath), administrative jobs to even martial requirements. And on ‘completion’ of the term, many of these young men (who had entered adulthood) were drafted as officers of the Macedonian army or as members of the elite corps of Companion Cavalry – thus alluding to a cyclic order of military support from the noble families.
3) Somatophylakes or Bodyguards –
Given the sometimes confusing accounts from ancient writers, historians can only deduce that the Somatophylakes or Bodyguards probably comprised a separate unit within the ancient Macedonian army. One of the clues comes from the position of the Royal Bodyguard (Somatophylax Basilikos) – which was considered as the senior-most rank in the army. Originally, there were seven such high-ranking officers, with the number symbolizing their first-hand duties that entailed guarding the massive royal tent. To that end, it is known that Alexander’s closest friend Hephiastion commanded the Bodyguards at the famous Battle of Gaugamela.
In essence, it can be hypothesized that the Somatophylakes took an active part in actual military encounters, though their numbers were probably very low – in the range of just 200 men. On occasions, they possibly even functioned as the Hypaspists, the shield-bearers we will talk about later in the article. However, beyond their martial capacity, it is their origins that have perplexed historians.
For example, Diodorus talked about how the king’s friends or philoi had sent around 50 of their sons to serve as bodyguards in the Macedonian army of Alexander. Curtius, on the other hand, talks about how these ‘bodyguards’ performed the function of Royal Pages, which goes against the Macedonian norm that forbade noble male adults from performing menial tasks. But if we combine the two elements, we can deduce the possibility of the Somatophylakes being recruited from the Royal Pages who had shown their martial acumen (upon entering adulthood). Simply put, the Bodyguards was an active combat unit (manned by the elite warriors who swore to protect their Basileus) and possibly also an institution for officer training and even staff support.
4) The Hetairoi Cavalry –
The Hetairoi or Companion cavalry was in many ways a military extension of the political framework of ancient Macedon centered around the king himself. As we mentioned before, most members of this elite cavalry regiment were recruited from the nobles (and their sons), and they possibly numbered around 1,800 men, divided into 8 squadrons (ilai), before the start of Alexander’s momentous expedition into Asia. Among these units, the Royal Squadron (Basilike Ile) with its double numbers held the position of honor in battles, and such its members were usually drawn from the Personal Companions and Friends (philoi) of the Basileus.
Befitting the elite ‘hammer’ of the Macedonian army, the Hetairoi flaunted their uniforms, with the Royal Squadron members ostentatiously displaying purple cloaks or chlamys (dyed with Tyrian purple) with golden yellow borders – many of which were confiscated from the Persian treasury. They were also presented with standard yet flexible cuirasses, possibly made of small metal pieces that were reinforced with leather or covered in white linen, along with the Boeotian helmets that replaced the earlier Phyrgian models. On the offensive avenue, the Companion cavalrymen were equipped with the lengthy xyston spears usually made of sturdy cornel wood, and these were backed up by the secondary weapons of swords.
Interestingly enough, there may have been a conspicuous absence of shields – the mainstay of Greek warfare, when it came to cavalry maneuvering, except on rare occasions. And since we brought up the scope of defensive equipment, it is widely known that Alexander himself preferred to ditch his cuirass in favor of just his tunic, probably to enact bouts of bravado during the earlier parts of the expedition (or possibly due to the heat). Suffice it to say, fueled by the personality cult of Alexander the Great, many of the impressionable noble youths from the cavalry regiments may have also tried to mimic their leader and charged into the battle – wearing just their ritzy tunics and armed with the xysta.
5) The Pezhetairoi or Foot Companions –
Before the Macedonian army crossed the Hellespont, the mainstay of their infantry comprised the Pezhetairoi (or Foot Companions) – men who the formed up the dreaded ‘anvil’ of the phalanx. Numbering around 9,000, these infantrymen were divided into six battalions (taxeis) – each comprising three lochoi. And mirroring the honored units of their cavalry counterparts, the Pezhetairoi possibly had an elite taxis of their own known as the Asthetairoi, with its members (preferably) recruited from Upper Macedonia.
Now in terms of equipment, ancient writers and pictorial evidence rather paint a vague picture of the renowned Macedonian phalangites. According to Polyaenus’ account of Macedonian military training, the infantrymen of phalanx were supplied with bronze helmets (kranos) of the Phrygian variety, light shields (pelte), greaves (knemides) and their characteristic long pikes (sarissai). So as can be gathered from this small list of items, the armor is conspicuously missing. On the other hand, Diodorus talked about standardized forms of armor being issued during the tough Indian campaign, thus suggesting how at least some of the Pezhetairoi wore cuirasses. Interestingly enough, one of the accounts of Polyaenus anecdotally entails how Alexander himself armed the men who had previously fled the battlefield with a hemithorakion – a half armor that only covered the front part of the body so that the soldiers wouldn’t turn their backs on the enemy.
In any case, as we fleetingly mentioned, beyond the scope of their armor, it was the bristling set of pointed sarissai that presented a nigh-impenetrable (albeit rigid) formation of the Macedonian phalangites. The longest of these sarissa pikes reached 18 ft during the times of the Wars of the Successors after Alexander’s death. Considering the defensive attitude of his successors, it can be assumed that in Alexander’s lifetime the sarissai were possibly somewhat shorter. These lengthy spears were also known their distinctive small iron heads that were more conducive to breaching the armor of the enemy.
6) The Hypaspistes or Shield Bearers –
Many historians have theorized that the Hypaspistes (‘Shield Bearers’) had their origins as retainers of the Companions of the royal court (not to be confused with the Hetairoi Cavalry), while others have hypothesized that they evolved from the mainline Pezhetairoi infantry. In any case, they probably bore a higher rank than the members of the Macedonian phalanx, and such also comprised an agema (vanguard) known as the Royal Shield Bearers (Basilikoi Hypaspistes). This unit, made up of taller candidates, expressly took the position of honor on the battlefield on the right side, supported on the left by other lochoi of Hypaspistes – and together they possibly had a strength of around 3,000 men.
Now considering the relatively rigid tactics of the aforementioned Pezhetairoi, it can be surmised that the Hypaspistes probably fulfilled a flexible battlefield role that bridged the gap between the mobile cavalry and the ‘stagnant’ phalanx. Judging by this requirement for agility, it can be assumed that the Hypaspist wore less armor when compared to his infantry comrades of the Macedonian army. To that end, Alexander may have equipped many of his Hypaspistes in a manner similar to that of Greek hoplites, thus suggesting the usage of Phyrgian helmets, lighter tunics, and shorter spears.
At the same time, these Shield Bearers formed the crack units of the army, and they proved their worth in many a siege battle, by taking part in the frontal assaults conducted within cramped quarters. In essence, it is fair to assume that the Hypaspistes were better trained and drilled than most contemporary infantry units, while their (required) agility kept them at the peak of their physical conditions. Given their esteemed martial value, many of the veteran Hypaspistes possibly also formed the renowned Argyraspides – the ‘Silver Shields’ who later took part in the Wars of the Successors after Alexander’s death.
7) The ‘Multinational’ Force –
Our popular notions about the ancient army commanded by Alexander the Great in his renowned campaigns mostly harks back to a homogenous Greek-speaking force comprising of the ‘anvil’ phalanx and the ‘hammer’ cavalry. However, in truth, the ‘Macedonian army’ was composed of soldiers who came from different backgrounds and nationalities. For starters, the Macedonians themselves, who formed up the ‘Royal Army’, were bolstered by their vassals, including the Triballians, Agrarians, Odrysians and even Illyrians – their former enemies. Alexander was also the de-facto head (archon) of the Thessalian army and the commander of the League of Corinth that gave him the power to levy military support from the Greeks. Added to this mix were the mercenaries, most of whom hailed from the southern Greek realms and the neighboring Balkans.
In fact, contrary to our modern concept of political correctness, there was rampant racism and pre-conceived ideas directed against other groups within the army. For example, the southern Greeks perceived their northern Macedonian brethren as being uncouth and even semi-civilized. The Macedonians, on the other hand, regarded their southern neighbors as being effete and soft. And both these essentially Greek groups identified the Thracians as barbarians, on account of their foreign language and boisterous tendencies. However, in spite of these cultural differences, the ‘hotch-potch’ of Alexander’s force was admirably successful in conducting long-lasting campaigns while enduring logistical obstacles – feats that were only matched by Hannibal and his army of ‘multinationals’ more than 80 years later.
8) The Thessalians and Thracians –
With all the talk about the elite Companion Cavalry, it may come as a surprise that it was actually the Thessalians who were considered as the finest horsemen in the Macedonian army (and possibly even the whole Greek world). Many of these valued cavalrymen were borne by the equestrian culture prevalent in the Thessalian noble class – and as such their regiments possibly mirrored the structure of the much heralded Hetairoi. To that end, ancient sources talked about how 1,800 Thessalian horsemen took part in Alexander’s Asia expedition, a number matched by the Companion Cavalry forces. Consequently, it can be assumed that they were similarly divided into eight squadrons (ilai), with the agema (vanguard) pertaining to the Pharsalian squadron – the Thessalian counterpart to the Royal Squadron (Basilike Ile) of the Hetairoi. As for their attire, the Thessalian horsemen probably wore their distinctive dark purple cloaks with white borders, while being armored in the similar white-hued cuirasses preferred by the Companions.
The Thracians, on the other hand, were perceived as an unruly bunch by their Greek neighbors. Nevertheless, they were renowned for their effective light cavalry forces. The Prodromoi (scouts) was one such Thracian unit that was attached to the Royal Army (comprising only Macedonians), and they possibly consisted of four squadrons. And even beyond the official designations of Prodromoi cavalry, the Macedonian army was often reliant on Thracian auxiliary cavalry – as they were suited to essential scouting and raiding activities inside enemy territories. In terms of panoply, the Prodromoi wore light tunics (without armor), possibly complemented by rose-colored cloaks (and the panther-skin shabraque for officers). They were also known to carry the longer sarissai instead of the sturdier xysta preferred by the heavy cavalry regiments.
9) The Allied Greeks –
Delving into the scope of the infantrymen, earlier we talked about how around 9,000 Pezhetairoi (or Foot Companions), the main phalanx force of the Macedonian army, were assembled for Alexander’s incredible military expedition. They were accompanied by 3,000 Hypaspistes (or Shield Bearers) and around 7,000 allied Greeks. Pertaining to the latter, it has been hypothesized that some of these allied Greek forces (along with mercenaries) were possibly relegated to garrison duties after crossing the Hellespont. Nevertheless, it can also be assumed that the Greeks of the League of Corinth were pretty well drilled, mainly because of their own set of reforms initiated after the disastrous defeat at Chaeronea (ironically handed by the Macedonians of Philip II).
One significant outcome of these reforms related to the phasing out of the typical ‘militia’ Greek hoplites in favor of the epilektoi (picked troops). Unlike hoplites, however, these epilektoi had to be paid on a regular basis – a system that often severely affected the fiscal condition of many individual city-states. And in terms of armor, most of these infantrymen adopted the heavier ‘muscled cuirass’ and the ubiquitous Phrygian helmet. It should also be noted that some Greek city-states offered their military support in the form of cavalry forces. Diodorus talked about at least such 600 Greek horsemen crossing the Hellespont with the main expeditionary force, and they were possibly reinforced by other detachments later in the campaign.
10) The Mercenaries and Other Troops –
In addition to around 3,600 heavy cavalry forces (comprising the Hetairoi and Thessalians), complemented by around 1,400 light cavalry troopers (comprising Thracians, Greeks, and other auxiliaries), the Macedonian army of Alexander also inducted mercenary horsemen. In fact, judging by the aforementioned figures, Alexander desperately needed more light cavalry, not just to balance his forces, but also for scouting activities in deep enemy territories that often played their part in strategic decision making. These mercenaries, possibly arranged in two squadrons, fought under the umbrella of ‘Foreign Mercenary Cavalry’ – and as such proved their worth against mighty equestrian opponents like the Bactrians and Scythians at Guagamela.
And beyond the scope of standard infantrymen and cavalry, the Macedonian army presumably also had its fair share of light skirmishers (psiloi), who fought in front of the packed phalanx formations – though not much is known about their numbers. What we do know, however, is that Alexander specifically recruited a company of the renowned Cretan archers (toxotai), and they were known for carrying their bronze pelte (light shield) that also aided them in close-combat scenarios.
Interestingly enough, other than archers, the light troops that played their instrumental role in many a military encounter, pertained to the peltasts and javelinmen (akontistai). The most famous of them arguably related to the crack troops of Agrianians, who numbered around 1,000 and carried both short and long javelins. And while grouped under the general term of ‘Thracians’, Diodorus also talked about 7,000 multinational light troops accompanying the main Macedonian army at Hellespont – and they possibly comprised akontistai contingents of the Triballians, Odrysians, and Illyrians.
Honorable Mention – The March
The basic tactical unit in the Macedonian army was known as the dekas, which contrary to its allusion to the number 10, actually consisted of sixteen man – equivalent of a single file in a square formation of the phalanx (comprising 256 men). Each dekas was officially allowed to have only one servant, known as ektaktoi, and his job entailed looking after the precious baggage (containing the main tent and other accessories) of the combatants, usually carried by mules, horses and later even camels.
Now in spite of such frugal means and lack of actual pay (that was usually replaced by the plunder taken from enemy settlements), the infantrymen who had joined Alexander in 336 BC and then embarked on his Asia-bound campaign, had traveled more than 20,870 miles (or 33,400 km) by the time Alexander breathed his last in Babylon (in 323 BC) – according to a calculation made by historian Theodore Ayrault Dodge. So, on an average, each of these men had covered an impressive 1,605 miles (or 2,570 km) per year! And, when translated in geographical terms, many of the Macedonian veterans could have claimed to cross a multitude of rivers including the Nile (in Egypt), Euphrates and Tigris (in Iraq), Oxus (in Tajikistan), Syr-Darya (in Uzbekistan) and the Indus (in Pakistan).
