Overall Size of Army Companies

March 18, 2025

The military hierarchy of ranks still used in the twenty-first century was already in place by 1600 [C.E.]. A colonel was assisted by a lieutenant-colonel who commanded in his absence. A major supervised training and administration and could command part of the regiment if it became detached from the rest of it. These three ‘staff officers’ were supplemented by secretaries, chaplains, doctors and a provost in charge of punishment. The same pattern was repeated in each company, with the captain assisted by one or two lieutenants, together with an ensign (called a cornet in the cavalry) responsible for the flag. There was generally also a company scribe, a barber surgeon and a number of non-commissioned officers (NCOs). Together, these senior ranks were known as the prima plana, or ‘first page’, on account of their names being listed before all the others in the muster register. The overall size of foot companies fell from three to four hundred, to two to three hundred over the sixteenth century, with cavalry companies averaging around half these sizes. The number of officers remained the same throughout, reflecting the growing emphasis on hierarchical order and enabling more complicated manoeuvres to be carried out….

The officer-to-men ratio remained relatively static after 1590, because of the technical limitations of the available weapons that required them to be used en masse. Around one officer or NCO could supervise about fifteen soldiers, but captains found it hard to command more than three hundred, as the smoke and noise of battle limited their ability to see what was happening and to shout instructions. This was another reason why infantrymen were packed close together in large formations, since it kept them within the sight of their mounted colonel. The flags and drums would be grouped in the centre and used to signal commands to the rest of the unit. Command problems also placed a premium on experienced men and it was reckoned at least a third of the strength had to be veterans to provide cohesion and sufficient old soldiers to teach new recruits the rudiments of drill and how to survive the rigours of campaign….

Feudal Military Organization Was on the Whole Highly Effective

April 15, 2024

But whatever his antecedents, the feudal knight was an important cog in the military machinery of the eleventh and twelfth centuries [C.E.]; and although Sidney Painter may have been guilty of some exaggeration in his summary of the achievements of European military feudalism, his opinion is worth quoting:

Feudal military organization was on the whole highly effective. The knights of Europe conquered vast territories from the Slavs, pressed the Moslems steadily back in Spain and drove them from Sicily, and established themselves at least temporarily in Palestine, Syria, the Byzantine lands, and Greece. As a defensive system feudalism was almost perfect. No organization ever devised could so quickly produce an effective military force wherever it was needed. The feudal army was essentially a militia, but a militia composed of the best soldiers of the day.

Perhaps so strong an assertion was needed to put the accomplishments of the feudal knight in proper perspective.

Origin of the Regiment and Battalion

March 9, 2024

The optimum combination of pike and shot, both as a numerical ratio and as a form of deployment, remained hotly debated in military treatises. Setting aside the numerous theoretical models, essentially only two formations were used in the field. Those adopting the Dutch-style counter-march needed thinner lines and more shot than pike, deploying a ratio of two to one in a ten-rank line by the 1590s [C.E.], with the pikemen in the centre, flanked by equal numbers of musketeers. The Spanish and imperial infantry favoured the larger, deeper formations that had been the norm earlier in the sixteenth century. Their pike were grouped as a central block with always twice the number of men in each line as there were ranks deep, because each man needed twice the amount of space in depth as in width to wield his weapon. The effect was to produce a square block that would be flanked by ‘sleeves’ of musketeers. An additional three to five ranks of light arquebusiers generally lined the entire front to maximize firepower. If caught by a cavalry attack, the musketeers could shelter under the pikes that would stretch over their heads. When attacking enemy foot, the arquebusiers would retire round the flanks once they had fired, leaving the pike free to charge. Spanish and imperial commanders sometimes grouped additional blocks of musketeers on the four corners, which can be seen in many battle engravings from the early seventeenth century. This was simply a formation for deploying and advancing, and the additional shot would fan out towards the enemy to fire, falling back to a less exposed side of the square if the formation came under attack.

The large square formation has become known as the tercio after the term used by the Spanish for their infantry regiments, while the thinner, longer Dutch formation is called a battalion. It has become a historical convention to see the latter as inherently superior to the former, not least because of its association with firearms that have appeared to later generations as obviously more advanced than pikes, weapons first used by the ancient Greeks. This distinction is not accurate, nor does it correspond to sixteenth-century military thinking that drew directly on the ancient world for its inspiration. The deeper block formations offered better all-round fighting ability than the thinner Dutch lines, where each unit relied on its neighbours standing firm or its vulnerable flanks would be exposed if the enemy broke through. Though only the first five ranks of the tercio could fire at any one time, the presence of another ten or more behind stiffened the resolve of those in front, or at least made it harder for them to run away. The unit assumed a more imposing presence on the battlefield; something that was a considerable advantage as it bore down on a wavering foe. In an age of black powder, the battlefield soon filled with smoke, making it extremely difficult for commanders to see what was happening. It was easier to lose control of long thin lines, composed of smaller, but more numerous battalions, than a deployment of fewer, larger tercios. These could be positioned en échelon, or diagonally staggered in chequerboard fashion about 200 metres apart. If one became detached or separated, it was generally large enough to fight on alone until rescued.

There was a trend towards increasing the ratio of shot to pike and to stretch formations into thinner lines that became pronounced in the 1630s, as we shall see later. It was partly related to minor technological advances producing the lighter muskets, and possibly also to pressure from soldiers themselves. Recruits generally preferred becoming musketeers rather than pikemen, who often had to stand under fire without personally being able to retaliate. Pikemen had originally received higher pay and were still seen by officers as more honourable than musketeers. Men who rose from the ranks did so ‘from the pike up’ (von der Pike auf), and not from the musket. Pikemen killed using cold steel, like the traditional knight’s lance, whereas musketeers relied on the devilish invention of gunpowder producing thick clouds of acrid smoke, striking their foes from a distance, rather than looking them in the eye. Pikemen also accused their more lightly equipped colleagues of being more prone to plunder, whereas they could not enter houses with their long weapons—something that clearly had a ring of jealousy to it. Certainly, pikemen were more likely to throw away their weapons if their formation broke, thus becoming defenceless, whereas musketeers could flee still fully armed.

The trend towards more shot around 1590 was also due to the deployment of musketeers in smaller, looser formations to open a battle or to delay an enemy while the rest of the army assembled. Parties of 50 or more musketeers would be pushed out in front of the main line, covered by groups of 250 pikemen as a reserve and rallying point. Such methods anticipated those of 200 years later, but generally disappeared around 1630 with the growing emphasis on massed, disciplined firing by ranks developed by the Dutch and copied by the Swedes. Given the inaccuracy of individual shots, commanders emphasized the volume of fire, and later also its rapidity, culminating in the disciplined firing by platoons adopted around 1700.

End of Medieval Warfare

February 24, 2024

The first important break from the conventions which dominated medieval warfare was the triumph of the Swiss pike-squares over the mounted knights of Burgundy in a series of pitched battles (1475-7 [C.E.]). The lesson of Morat, Grandson, and Nancy was immediate, important and ineluctable: victory in battle could be won by infantry over cavalry. This shift in military effectiveness removed a crucial restriction on the scale of warfare in Europe. Since a warhorse was not only expensive but also a mark of social rank the size of a cavalry-based army was necessarily circumscribed by the dimensions of the social class which was entitled to go through life on horseback: the knights. There was no such bar to the number of men who could be recruited and issued with a helmet and sixteen-foot pike. Accordingly the eclipse of cavalry by infantry meant that victory in war after the 1470s came to depend not on the quality of the combatants nor on the excellence of their armament, but on their numbers. A government bent on war had now to mobilize and equip every man who could be found.

Captains Held Enormous Power Over Their Companies

January 25, 2023

Every captain in an early modern army held enormous power over the rank and file of his company. In absolute charge of discipline he could flog, fine, or otherwise humiliate his men whenever he chose; because he alone decided who should perform sentry guard and other onerous duties, the captain was free to victimize the men he disliked and excuse his friends…. [Without] interference from above, [a Spanish Empire] captain chose the two sergeants and eight corporals of his company (the cabos de escuadra or corporals were in charge of twenty-five men and received a wage-bonus of 3 escudos each per month), and he distributed at his pleasure 30 escudos of treasury bonus-pay among his men. As if this were not enough, the insolvency of the military treasury made the company captains into money-lenders and welfare-officers as well. Every company had a chest (caja) kept by the captain and used by him to advance subsistence wages (the socorro) to necessitous men when no money arrived from the treasury. The captains were also responsible for ransoming, re-arming, or re-horsing any of their men who had the misfortune to lose their liberty, their weapons, or their mounts. Naturally when the treasury did contrive to pay an [installment] of wages the captains expected to receive it first in order to deduct the sums already advanced “on account”. The scheme was excellent in principle, but it assumed that all captains were honest and scrupulous men. Of course they were not…. “The arrangements for paying the troops played right into the eager hands of the captains, who took full advantage of the generous opportunities afforded them.”

Not All Recruits Were Base-born: the Gentleman-rankers

January 21, 2023

Not all recruits were destitute or base-born, however. The Army of Flanders, especially in the sixteenth century [C.E.], needed quality as well as quantity; men who excelled in single combat, in the “actions” of the war, were required as well as cannon-fodder for the great battles. Every captain therefore tried to enlist a number of gentlemen (particulares) to serve as common soldiers in his company, offering a bonus-pay (ventaja) to every gentleman who agreed to do so. Some of these volunteers would be the relatives of the captain, others would no doubt be poor gentry unable to gain a living in other ways (Spanish gentlemen were not supposed to demean themselves by manual labour or commercial transactions), others still would be aspiring noblemen who began their military service in the ranks and hoped before long to rise to a position of command.

Most army commanders set the highest value upon these gentleman-rankers. The duke of Alva, for example, was overjoyed to find that a large number of particulares had volunteered to serve in the Spanish infantry which he led to the Netherlands in 1567.

Soldiers of this calibre [wrote Alva] are the men who win victory in the “actions” and with whom the General establishes the requisite discipline among the troops. In our nation nothing is more important than to introduce gentlemen and men of substance into the infantry so that all is not left in the hands of labourers and lackeys.

Throughout the Eighty Years’ War the same sentiment was expressed in remarkably similar terms. As late as 1640, for example, a Netherlander—and a civilian at that—could write:

Gentleman-rankers…are the people who bear the brunt of the battles and sieges, as we have seen on many occasions, and who by their example oblige and enliven the rest of the soldiers (who have less sense of duty) to stand fast and fight with courage.

Service as a volunteer among the infantry was particularly popular among the Spanish gentry, but particulares were also to be found in considerable numbers in the ranks of other “nations”. The English units in the Army of Flanders, for example, regularly included Catesbys, Treshams and other members of the leading recusant gentry families—including Guy Fawkes. Not all these gentleman-rankers were poor. On one celebrated occasion the Emperor Charles V lent additional dignity to the military profession by himself taking up a pike and marching with his men; later, in the 1590s, the dukes of Osuna and Pastrana and the prince of Asculi, scions of the most illustrious houses of Spain, were all to be found serving as simple soldiers in the Army of Flanders. Naturally these volunteers, especially the nobles, aspired to an eventual position of command, but they first received an admirable apprenticeship and, in addition, their presence in the ranks helped to maintain morale and reduce insubordination. In this way the Spanish Habsburgs assembled armies which were supremely capable of victory without resort to any compulsion.

Retinue Versus Followers

September 3, 2022

The retinue did not consist of only soldiers…but also of servants, artisans, professionals, estate officials, treasurers, stewards, lawyers and generally all that was needed by the normal operation of society. And, as the lord grew in status, so did the retinue; so that a sort of “bastard feudalism” developed, in which middle ranking figures under a king or major noble would compete for money, offices or influence…. The collective name for these retainers was “affinity,” which also happens to be a word that began in c. 1300 [C.E.] as “relation by marriage.” In a sense, the retinue were “kin,” or part of the “neighbourhood,” words that have developed other meanings over time. For this post, [we will] go on using the word retinue and retainer, but try to keep affinity in mind….

Obviously, this would mean that many persons outside the retinue would always be seeking to be a part of it, if they had no affinity of their own. This meant that outside the retinue were an amorphous group of general supporters and contacts, most of them completely unknown to the lord, but known to the various members of the retinue. Thus, even a minor lord could potentially affect hundreds, even thousands of persons, simply by their existence at the heart of his or her retinue. This made political maneuverings and the raising of an huge army a realistic possibility…. In [Dungeons & Dragons], we tend to think that to raise an army, we need to scatter out agents and interview people. In fact, the more likely truth is that there would be large numbers predisposed to our cause; we would need only to canvas our own connections, gain the support of other nobles and let them canvas their connections, and thus through specific persons already in our employ, we would dredge up the very people we needed from both our lands and from those wanting to be part of our lands. Thus, every war begins with a promise of land—which we will naturally take from the losers, when we win.

All this makes the retainer far, far more valuable than the follower—though, it must be said the retainer has less reason to be directly loyal. Ultimately, the retainer serves the office, not the individual. A lord is sure to be surrounded by trusted, reliable followers and henchmen, the “inner circle,” while sorting out the trusted members of the retinue from those not quite so trusted. In general, the retinue is expected to fall in line because the lord has the retinue’s general welfare at heart; if the lord fights to preserve the lord’s lands, he or she also fights to preserve the retinue’s lands. So all join together in the common cause.

An Army Open to Talents

March 12, 2022

[King Philip] had carried through a social revolution among the Macedonian military class…. The old nobility were laid under an obligation of regular military service; to it a new nobility of military adventurers was added, recruited and promoted on the basis of professional excellence. The result was an army ‘open to talents’, in which the king’s new and old followers competed for position in demonstrations of loyalty and self-disregard.

Retinue of Retinues

January 25, 2022

The phrase I drill into my student’s heads about the structure of medieval armies is that they are a retinue of retinues. What I mean by this is that the way a medieval king raises his armies is that he has a bunch of military aristocrats (read: nobles) who owe him military service (they are his ‘vassals’) – his retinue. When he goes to war, the king calls on all of his vassals to show up. But each of those vassals also have their own bunch of military aristocrats who are their vassals – their retinue. And this repeats down the line, even down to an individual knight, who likely has a handful of non-nobles as his retinue (perhaps a few of his peasants, or maybe he’s hired a mercenary or two on retainer).

…The average retinue…was five men although significant lords (like earls) might have hundreds of men in their retinues (which were in turn comprised of the retinues of their own retainers). So the noble’s retinue is the combined retinues of all of his retainers, and the king’s army is the combined total of everyone’s retainer’s retainers, if that make sense. Thus: a retinue of retinues.

Versatility of the Napoleonic Army Corps

May 2, 2008

Among the reforms of the army begun before the [French] Revolution was the development of the corps d’armée. Napoleon saw the value of this reform, adopting and developing it into what has been called his secret weapon. The Napoleonic army corps was a well-balanced unit comprising all arms: infantry, cavalry and artillery, with attached engineers, auxiliary trains and a headquarters staff. The corps was in effect an army in miniature, although its size, anywhere from 5,000 to 40,000 men, could rival that of many 18th-century armies. The corps would be made up of a number of infantry and cavalry divisions, each of two or more brigades with attached artillery. As Napoleon’s corps structured army went into battle against a traditionally organized enemy force, each of his corps, being a complete fighting force, could go into action without delay as soon as it arrived on the field. When [Marshal Louis-Nicolas] Davout, one of the pre-eminent corps commander of the period, brought his men by an epic forced march directly into the fray at Austerlitz, he undoubtedly stopped the great Russian envelopment of the French right which would have threatened to cut across Napoleon’s line of communication and make his position untenable. The size of a corps could vary and would depend on several factors, such as its particular task and the ability of its commanding general. To his step-son, Eugéne de Beauharnais, Napoleon in 1809 commented, ‘…a corps of 25,000-30,000 men can be left on its own. Well handled it can fight or alternatively avoid action…an opponent cannot force it to accept an engagement, but if it chooses to do so it can fight alone for a long time.

From Ghazi to Sipahi

May 2, 2008

The ghazi warriors who provided the original cutting edge of Ottoman expansion were land-hungry freebooters of diverse origins. An increase in the size of this group was essential if the Ottoman state was to continue expanding. The timar system provided an economic basis for a numerous class of such sipahis, whose obedience was ensured by institutionalizing denial of the hereditary principle in the Ottoman law of feudal land-holding, and whose appetite for warfare was stimulated by the enticing prospect of fresh plunder perpetually available across the frontiers of the empire. According to the Venetian ambassador…there were 80,000 sipahis in European Turkey in 1573 [C.E.] and 50,000 in the Asiatic provinces, together with 15,000 sipahis ‘of the Porte’, household cavalry who were paid by the treasury and did not receive timars. The sipahis remained an unruly class, militarily valuable but politically untrustworthy, whose turbulence it was necessary to balance and control by increasing the numbers and improving the efficiency of public administrators and by establishing a body of household infantry whose effectiveness on campaign and loyalty to the sultan were beyond question. It was in response to these requirements that the Ottomans of the fifteenth and sixteenth centuries developed slavery as a fundamental social institution; organizing by this means a supply of obedient and talented soldiers and administrators on a scale suited to the demands of a great imperialist power.

Assyrian Army of the Sargonid Period

May 2, 2008

The Assyrian army in the Sargonid period had a potential magnitude of several hundreds of thousands of troops, although a call-up of the entire force for a campaign was extremely rare. Supreme command of the army rested with the king and, immediately under him, the “field-marshal”…. The army was divided into units of various sizes and types; but the basic division was the “company”…of fifty men under a “captain”…and this unit was in turn broken down into files of ten men. An officer carried a mace as a symbol of his authority.

The levying of troops was the primary responsibility of the captains, each of whom had a certain number of villages under his command, and the captains were in turn responsible to the provincial governor. By the Sargonid age there was also a standing army which was under the direct authority of the king, no doubt created as a counter-balance to the potential misuse of military power by the provincial governors. The king also had his own bodyguard of infantry and cavalry. The troops recruited within Assyria proper were spread around the empire as much as possible, since they were the most loyal, and they constituted the chariotry and cavalry divisions. The infantry consisted largely of foreigners, mainly Aramaeans. Some foreign groups became specialized units. For example, the Ituaeans, an Aramaic people, were entrusted with special tasks such as escort duty throughout the empire.

Garrisons and barracks were scattered over the empire, but the military headquarters was a massive armoury in the Assyrian capital. Here was stationed a large portion of the troops, animals, and equipment of the standing army, and there were, in addition, royal apartments for the king to occupy when he wished. At each New Year there was a grand inspection at the armoury when the king reviewed his troops and their equipment….

Regimental Proprietary System

May 2, 2008
The establishment of permanent units hastened the almost universal adoption of the proprietary system, which had already begun to replace the vestiges of feudalism and of free companies. The permanent colonel was the proprietor of his regiment, accepted by the king as a permanent officer and authorized (personally, and through him his captains) to raise men. Initially, with armies being raised only for a campaign and disbanded afterward, the troops raised by the proprietary system were volunteers, more or less carefully selected from the available and willing manpower. But as the armies became permanent, the standing units were not disbanded and were kept up to strength by regular influx of recruits, usually provided by the crown. This, combined with the financial considerations in maintaining year-round units, gave the crown increasing rights of supervision over the administration and training of the regiments, and thus somewhat restricted the proprietary right previously exercised by colonels and captains.
This proprietary system could be profitable. A commander was paid for the number of men he mustered, as well as for their weapons, equipment, and subsistence. In addition to the profit to be derived from economical exercise of his proprietorship (to say nothing of the possibilities offered by parsimony and fraud), an officer could sell his proprietary interest when he retired. Thus officers’ commissions were valuable, and could be purchased. This custom of purchase of commissions continued in some armies—notably that of England—long after the proprietary system itself had disappeared.

Amir Grades of Rank

March 7, 2003

A brief explanation regarding the ranks of Mamluke ameers [sic] may here be useful. The government was divided into two distinct classes, “men of the pen” and “men of the sword,” civil servants and soldiers. The men of the sword at this period consisted solely of Turkish Mamlukes born on the steppes….

When the sultan wished to promote an efficient soldier to officer rank, he was given a commission and the rank of “an ameer of ten,” corrosponding, let us say, to a lieutenant. He was obliged to maintain ten mamlukes of his own, and was given a small fief of government land, on the income from which he had to live and maintain his ten mamlukes. In the event of war, the officer and his ten men served in the army, providing their own horses, weapons and supplies.

Next above an ameer of ten was an ameer of forty, who maintained forty trained mamlukes. We may compare this officer to a captain. At this stage, he was allowed to have a tablkhana, a small military band, consisting of drums, and possibly also cymbals, oboes and trumpets. The essential component was the drums, which were used in battle.

…The drums were not merely a military ritual, but played a vital part in battle. An ameer of forty was consequently often called “an ameer of drums”….

The next rank above ameer of drums was that of ameer of one hundred, whom we may liken to colonels. The establishment of ameers of one hundred under Baybars was twenty-four. These senior ameers were each supposed to have one hundred private mamlukes. They had larger bands than those of the ameers of forty. The sultan’s own band was larger still, and was commanded by a band-master. The drums were presumably side-drums or kettle-drums, for they were beaten on horseback.

Ameers of one hundred are often described as “commanders of one thousand.” The one hundred were the ameer’s personal retainers, always under arms. In war time, when the reserves were mobilized, the ameer commanded a thousand troopers. All real Mamluke units were mounted. They had no infantry and disliked fighting on foot.

In peace time, the sultan and all ameers of a hundred were entitled to have their bands play outside their houses at sunset. History does not explain what happened if several ameers lived next door to one another in the same street, for in Egypt all ameers seem to have had houses in Cairo. The resulting evening cacophany must have been trying for civilian neighbours….

Reasonably enough, the right to beat drums was a military privilege….

Military Systems

March 7, 2003

The military system of a state is explained by its resources, principally financial, the structure of its government and administration, the level of its technology, the organization of its society and the nature of its economy, but one must also take into account its objectives and strictly military imperatives. Every state in effect seeks to raise armed forces adapted to its ambitions and to its own fears. This was the case in England at the end of the Middle Ages when military institutions were founded as a result of the interaction of several factors. First, it was a society where the feudal regime had changed almost completely into a system of land tenures, creating the need to establish new personal ties between those who governed and the men who were capable of serving them in war—’bastard feudalism’. Secondly, the fact that the principal English strength lay in the massive use of the longbow, a weapon which was popular rather than aristocratic, led to the need to draw on the resources of every level of society, independent of juridical status, in order to recruit a sufficient number of highly qualified archers. Finally, the adoption of a deliberately aggressive and expansive foreign policy implied the sending of forces against Scotland, Wales and Ireland, but above all across the sea. These expeditionary corps had to be capable of waging war away from their base for six months, a year, two years or even more. Garrison troops, intended to hold permanently a certain number of places on the continent and also, if the need arose, capable of turning themselves into a proper army of occupation, were vital.

A Vast Encampment

March 7, 2003

Uninterrupted conquest was the law of life of Turkish society; the sultans emerged into the light of recorded history as leaders of a ghazi horde. Even when the empire had acquired a metropolis and was governed through a formal and elaborate administrative system, it remained almost continuously at war, a vast encampment rather than a state in the European sense. Until the advent of a succession of luxurious and fainéant rulers in the later sixteenth century [C.E.], sultans were active field commanders, usually quitting Istanbul with the army each spring and campaigning throughout the summer.

Three-Tier System of Administration for Military Orders

May 6, 2001

In the years immediately following foundation, a [Christian] military order [like the Knights Templar] consisted of a small group of brethren under the leadership of a master. At this stage little governmental machinery was needed. As property and recruits were gained, it became the norm to establish subordinate convents, both in frontier regions and elsewhere. If expansion was considerable, an intermediate tier of government between convents and the order’s headquarters was soon needed, as it became difficult for masters to supervise distant convents. Also, a system was needed by which resources and recruits could easily be channelled to frontier regions from other convents. Orders which fought on several fronts also required a military leader in each district. They adopted the practice of grouping the convents of a region into what were called provinces or priories. Although there were variations in detail, the leading orders adopted a three-tier system of administration.
