216 BCE — Cannae: Hannibal’s encirclement using cavalry feint, infantry draw, and reserves.
Subtitle: How ancient strategy shaped modern combined arms doctrine

OVERVIEW
The Battle of Cannae (216 BCE), commanded by Hannibal Barca, stands as a canonical example of ancient combined arms manoeuvre (CAM) doctrine. Its enduring legacy lies in Hannibal’s successful coordination of infantry and cavalry in a double envelopment—a manoeuvre where both flanks envelop the enemy. This battle exemplifies the synchronization of dissimilar combat arms to achieve strategic surprise and operational destruction. By integrating light and heavy infantry with agile cavalry and exploiting terrain and enemy momentum, Hannibal achieved a tactical masterpiece, referenced by later military theorists and practitioners from Frederick the Great to von Schlieffen. This prompt frames the battle’s structure through the lens of combined arms warfare to explore how ancient techniques prefigure modern doctrines of operational art and manoeuvre-centric combat.

KEY POINTS

1. Cannae as a Paradigm of CAM
   Hannibal’s order of battle at Cannae illustrates the integration of cavalry, skirmishers, and infantry to create mutually supporting elements, fulfilling the core concept of CAM as defined in ancient military practice.

2. Manipulating Enemy Expectations
   By deploying his weakest troops in the center, Hannibal lured the Roman legions into overextension, creating the conditions for envelopment. This feigned retreat was a deliberate operational deception.

3. Role of Cavalry Superiority
   Hannibal’s Numidian and Iberian cavalry played a decisive role, first defeating the Roman cavalry, then striking the Roman rear, closing the trap—an archetype of CAM exploitation of mobility and speed.

4. Operational Synergy Across Combat Arms
   The battle demonstrated a deliberate orchestration of actions—infantry fixated the enemy, while cavalry and flanking infantry created tactical shock. This illustrates early operational synergy central to CAM doctrine.

5. Dislocation and Strategic Shock
   By striking the Roman army’s unprotected rear, Hannibal introduced dislocation, preventing organized retreat. This reflects the CAM principle of attacking system vulnerabilities rather than strengths.

6. Force Structure and Flexibility
   Hannibal’s force disposition—African heavy infantry on the flanks, Celtiberian/Gallic troops in the center—allowed for a responsive and elastic defense that later formed the basis of the double envelopment.

7. Psychological Effects of Envelopment
   Envelopment inflicted psychological shock and paralysis on the Roman force, anticipating modern CAM’s goal of cognitive dominance and moral dislocation over mere physical destruction.

8. CAM Through Terrain Exploitation
   Hannibal chose terrain that constrained Roman movement and enhanced his own flanking mobility. This terrain control reflects CAM's imperative of environmental manipulation for tactical advantage.

9. Economy of Force and Massing Effects
   Despite being outnumbered, Hannibal achieved superiority at critical points via economy of force—a key principle of manoeuvre-warfare. Combat power was massed where it would yield decisive returns.

10. Command and Control in CAM
    The precision and timing of the envelopment required robust C2. Hannibal’s ability to orchestrate complex actions across multiple formations without modern communications highlights the centrality of initiative and mission command.

11. The Legacy of Cannae in Modern Doctrine
    Cannae has been repeatedly invoked in Prussian and German operational doctrines, most notably by von Schlieffen and later by NATO theorists. It serves as the foundational example of battle as operational manoeuvre.

12. Encirclement as CAM Decisiveness
    The outcome—complete Roman encirclement and annihilation—offers a classical expression of CAM’s ideal: not just winning, but decisively ending the enemy’s ability to fight, a core principle in operational design.

13. Synthesis of Ancient and Modern CAM Elements
    While Hannibal lacked modern logistics and communications, his tactical design and use of complementary arms align with modern definitions of CAM, emphasizing initiative, depth, and simultaneity in operations.

14. CAM as an Adaptive System
    Hannibal’s flexibility and adaptation to Roman doctrine, exploiting its rigidity, showcases CAM’s requirement for systemic thinking—fighting the enemy’s mind, not just their forces.

15. Educational Utility of Cannae
    Cannae’s study provides a didactic model in military education on the application of manoeuvre battle planning, and integration of disparate arms, bridging ancient theory with contemporary military education frameworks.

IMPORTANT NOTE—LIMITS OF OPERATIONAL SUCCESS:

While Hannibal’s tactical and operational brilliance—most famously demonstrated at Cannae—stands as a canonical example of ancient combined arms manoeuvre (CAM), his broader campaign reveals a timeless military lesson: operational success is not synonymous with strategic victory.

Hannibal achieved devastating battlefield results at Trebia, Lake Trasimene, and Cannae through innovative use of cavalry, infantry, and terrain. Yet these victories failed to break the Roman alliance system or secure peace on Carthaginian terms. Central to this failure was the Roman adaptation under Fabius Maximus, whose Fabian strategy—the deliberate avoidance of pitched battle and systematic denial of Hannibal’s foraging opportunities—gradually undercut Hannibal’s campaign. By depriving him of resupply and wearing down his forces through attritional pressure, Rome forced Hannibal into a war of exhaustion he could not sustain.

This pattern is mirrored in the Wehrmacht's 1942 Eastern Front campaign. During Case Blue, German forces executed a series of stunning operational advances and encirclements, but they failed to achieve strategic effect. Overextended lines, insufficient logistical infrastructure, and a lack of clear political objectives rendered these victories hollow. Despite localized successes, the inability to compel Soviet collapse or secure sustainable territorial gains revealed the same gap Hannibal faced: no strategic framework to consolidate operational achievements.

These cases illustrate a central truth in military history: tactical and operational excellence must be subordinated to coherent strategy and logistical reality. Without that, even the most celebrated campaigns risk becoming operational dead ends.

OPERATIONAL SUCCESS TRANSLATED INTO STRATEGIC VICTORY—THE SIX-DAY WAR (1967)

In stark contrast to Hannibal’s and the Wehrmacht’s campaigns, the Six-Day War (1967) provides a textbook case where combined arms manoeuvre (CAM) at the operational level yielded swift and decisive strategic victory.

Israel’s military orchestrated a coordinated, multi-domain campaign against Egypt, Syria, and Jordan, leveraging surprise, air superiority, and rapid armored advances. The preemptive strike on Arab air forces (Operation Focus) rendered enemy air power ineffective, ensuring air dominance. Ground forces—armored, mechanized, and infantry units—then executed rapid envelopment and penetration manoeuvres, particularly in the Sinai, West Bank, and Golan Heights.

This campaign was marked by:

• Deep coordination across air, land, and command elements;

• Flexibility and initiative in command structure;

• Operational tempo that paralyzed adversary reaction cycles.
  
  

Most crucially, these tactical and operational actions were tightly aligned with clear strategic objectives: neutralizing existential threats and achieving defensible borders. The result was a strategic transformation of Israel’s regional position, with territorial gains that altered the strategic calculus in the Middle East for decades.

The Six-Day War illustrates CAM at its best: not only operational brilliance but a direct, coherent linkage to political-military objectives, making it a key counterexample to Hannibal’s and the Wehrmacht’s campaigns.
