The Poor Fellow-Soldiers of Christ and of the Temple of Solomon—better known as the Knights Templar—remain one of the most studied armed orders of the crusading era. Their reputation for discipline, cohesion, and tactical sophistication on the battlefield is well earned, yet one aspect of their operational art often receives less attention than it deserves: the deliberate husbanding and deployment of operational reserves. For the Templars, reserves were not merely a safety net; they were a decisive weapon. Their ability to keep a potent force out of the initial engagement and then commit it at a precisely chosen moment frequently turned the tide of campaigns and stands as a model of medieval command.

The Templar Military Structure and the Role of Reserves

To understand how the Templars wielded reserves, one must first grasp how their army was organized. By the mid-12th century, the order fielded three principal types of troops: knights (heavily armored cavalry), sergeants (lighter cavalry and infantry), and turcopoles (native light cavalry). A typical Templar battle array placed the knights in the first line—the prima acies—supported by sergeants and infantry. Behind this main body stood a second line and, further back, a third line composed of the best knights and most experienced sergeants. This rear echelon constituted the reserve.

Why a Reserve?

The need for a reserve stemmed from the fundamental uncertainties of medieval combat. Battles rarely unfolded according to prearranged plans. Cavalry charges could overrun an enemy flank but also could be repulsed and disordered. Enemy feints or flanking movements could suddenly threaten the Crusader rear. A commander who committed every man in the first assault left himself no means to respond to such surprises. The Templars, drawing on centuries of Roman and Byzantine military thought filtered through their own hard-won experience, realized that a well-timed reserve could restore a wavering line, exploit a gap, or cover a retreat.

Moreover, the Crusader states were chronically short of manpower. The Templars could not afford to waste knights in futile attacks or disorderly pursuits. By keeping a portion of their forces fresh and under direct control, they maximized the combat power of their limited numbers. A reserve allowed them to apply force economically and precisely—principles that John Keegan later identified as hallmarks of professional armies.

Reserves in Action: Key Battles of the Templars

The Battle of Montgisard (1177)

One of the finest examples of Templar reserve usage occurred on 25 November 1177 at Montgisard. King Baldwin IV of Jerusalem, though gravely ill with leprosy, led a small Crusader army—perhaps 500 knights (mostly Templars under their Grand Master Odo de Saint-Amand) and a few thousand infantry—against Saladin’s much larger force, estimated at 20,000–30,000 men. The initial Crusader attack was a desperate gamble. The first line of knights charged into the Ayyubid vanguard, but the sheer weight of enemy numbers threatened to envelop them. At this critical moment, the Templar reserve, which had been stationed behind a low ridge west of the battlefield, was unleashed. These 80 to 100 heavily armored horsemen struck the Muslim right flank just as the main Crusader charge began to stall. The shock was physical and psychological. Saladin’s troops, already engaged to the front, saw fresh knights appear on their flank, and morale collapsed. The Ayyubid army fled, leaving Saladin’s personal guard dead around him. Modern historians such as Malcolm Barber and Steven Runciman credit the Templar reserve with saving the Crusader army from annihilation and turning a near-disaster into a stunning victory.

What made the reserve so effective at Montgisard? Positioning and timing. The Templars had concealed their reserve behind terrain that masked its approach until the final moment. They committed it when the enemy’s attention was fully fixed on the front, and when the initial Crusader assault had already created disorder in the Muslim ranks. The reserve thus operated as a force multiplier, multiplying the psychological effect of the charge.

Battle of Arsuf (1191)

A generation later, Richard the Lionheart, working in close coordination with the Templars, displayed a more defensive use of reserves at Arsuf. Richard’s plan was to march his army south from Acre to Jaffa under constant harassment by Saladin’s light cavalry. He organized his column with infantry on the seaward flank, cavalry in the center, and the Templars as the rearguard. The Templars were effectively the army’s rear reserve: they absorbed the worst of the Muslim attacks, allowing the main body to advance steadily. When Richard finally gave the signal for a general charge, the Templars—still fresh because they had mostly held back—led a devastating cavalry attack that broke the Ayyubid pressure and secured the Crusaders’ arrival at Jaffa. Here the reserve’s role was less about offensive shock and more about protecting the army’s cohesion while preserving combat power for the decisive moment.

The contrast between Montgisard and Arsuf illustrates the dual nature of Templar reserves: they could deliver a winning counterstroke (offensive) or shield the main force from attrition (defensive). In both cases, the reserve was saved for the decisive action rather than frittered away in skirmishing.

Battle of La Forbie (1244)

Not all Templar reserve operations succeeded. At La Forbie, near Gaza, the Crusader army, which included a large Templar contingent under Grand Master Armand de Périgord, was surprised by Khwarezmian and Egyptian forces. The Templars initially deployed in the center with a reserve behind them. However, the speed of the enemy attack and the collapse of the allied Ayyubid troops on the flanks made it impossible for the Templar reserve to be effective. They committed it piecemeal, and it too was overwhelmed. The disaster at La Forbie, where hundreds of Templars died, demonstrates that even a well-conceived reserve cannot function if the overall battle plan unravels before it can be committed. Reserve management requires not only good troops but also situational awareness and the ability to control the tempo of battle—something the Crusaders lost at La Forbie.

Tactical Mechanics: How Templars Controlled and Deployed Reserves

Signals and Command

The Templars developed a sophisticated system of battlefield communication. Knights were trained to recognize pennons and banners—especially the famous black-and-white Beaucéant—which signaled the location of the commander and the direction of movement. Trumpets were used to order charges and withdrawals. The reserve commander typically had his own distinct banner and a trumpeter, allowing him to receive orders from the Grand Master or the overall Crusader commander even amidst the din of battle. This discipline was crucial because a reserve committed too early could be wasted; committed too late, it might arrive after the battle was lost.

Positioning and Terrain

Templar tactical doctrine prescribed that the reserve be placed behind a masking feature if possible—a rise, a wood, a reverse slope. This concealment served two purposes: it shielded the reserve from enemy observation (denying the enemy knowledge of its strength and location) and it increased the shock of its appearance when it emerged. At Montgisard, the low ridge east of the battlefield provided exactly such concealment. At Arsuf, the Templars used the dust clouds and the press of infantry to mask their numbers until the signal was given.

When natural cover was absent, the Templars sometimes deployed their reserve in a column or a deep formation directly behind the main battle line. This allowed rapid forward movement but sacrificed surprise. The choice depended on the tactical situation and the enemy’s capacity to react.

Training and Discipline

Maintaining a reserve under combat conditions requires extraordinary discipline. Troops withheld from the initial clash often feel frustrated, fearful, or eager for glory. The Templars solved this through rigorous training and a strong ethos of obedience. Knights took vows of obedience to the Grand Master, and this carried into battle. A Templar who broke ranks without orders faced severe punishment, including expulsion from the order. Such discipline ensured that reserves would await the command and not charge prematurely.

Furthermore, Templar reserves were often composed of the most experienced knights—those who had proven their coolness under fire. These men could be trusted to hold formation and follow orders even when comrades in front were falling. Their experience also made them more effective when finally committed, as they could recognize weak points in the enemy line and exploit them without needing explicit guidance.

Benefits of the Reserve Strategy

The systematic use of reserves conferred several advantages that distinguished Templar armies from many feudal hosts of the 12th and 13th centuries:

  • Battlefield agility: Reserves allowed the commander to react to enemy actions without losing the structure of the main line. If the enemy threatened a flank, the reserve could be shifted to shore it up.
  • Morale reinforcement: Troops in the front line knew that fresh comrades stood behind them. This confidence increased their staying power. Conversely, the enemy’s belief that they faced only limited opposition could be shattered when a fresh formation appeared.
  • Offensive surprise: A hidden or withheld reserve could be used to create a sudden local superiority of force, overwhelming a specific sector of the enemy line.
  • Economic use of force: By committing only the minimum forces needed to hold the enemy, the Templars conserved their precious knights for the moment when they could make the greatest impact. This principle of economy of force is still taught in military academies worldwide.
  • Control of retreat: Not all battles are winnable. A reserve could provide a rearguard screen to allow a defeated army to break contact and withdraw in order. The Templars used this tactic during the ill-fated expedition to the Sea of Galilee in 1187, though ultimately the main army was destroyed at Hattin.

Risks and Limitations

No tactic is foolproof. The Templar reserve system had vulnerabilities:

  • Indecision: A commander might hesitate to commit his reserve, waiting for the perfect moment that never comes. Such indecision could allow the enemy to defeat the main line in detail.
  • Isolation: If the enemy had his own reserve or could rapidly redeploy, the committed Templar reserves could become trapped and surrounded, as occurred at La Forbie.
  • Communication failures: In the chaos of battle, orders to the reserve might be delayed or misheard. The noise of combat, the dust, and the limited visibility all complicated command and control.
  • Morale of the reserve: Troops held back for too long might become demoralized, especially if they saw their comrades being slaughtered. Templar discipline mitigated this, but it remained a factor.

Legacy and Influence

The Templar approach to reserves did not vanish with the order’s dissolution in 1312. Later medieval commanders, such as the English during the Hundred Years’ War (think of the reserve at Agincourt), and the Swiss in their pike battles, employed similar concepts. Renaissance military theorists like Niccolò Machiavelli advocated for a reserve line in his Art of War, though he may not have explicitly credited the Templars. In a broader sense, the Templars demonstrated that a small, highly disciplined force could achieve disproportionate results through superior command and control—a lesson that echoes in modern military doctrine through the concept of the operational reserve.

Historians continue to debate the extent to which the Templars consciously developed a “system” of reserve employment versus simply reacting to circumstances with common sense. Yet the evidence from multiple battles suggests a deliberate pattern. The Templars understood that victory often goes not to the side that fights hardest, but to the one that fights smartest—and saving a portion of one’s strength for the decisive moment is perhaps the smartest tactic of all.

Conclusion

The Templar Knights’ strategic use of reserves was far more than a footnote in medieval warfare. It was a core principle of their tactical doctrine that enabled a relatively small military order to influence the course of the Crusades for nearly two centuries. By holding back a portion of their force, they gained flexibility, preserved combat power, and could deliver devastating counterstrokes at opportune moments. Battles such as Montgisard and Arsuf showcase the payoff; La Forbie offers a cautionary tale of what happens when the system breaks down. In the end, the Templars’ mastery of reserves reveals that, even in the age of clashing broadswords and thundering hooves, the intellectual side of command—the ability to hold back and then commit with precision—was decisive. Modern commanders from Napoleon to Rommel would echo this lesson: the side that controls the reserve often controls the battlefield.
