What is a Flanking Maneuver?

Defining the Maneuver

In the domain of military tactics, a flanking maneuver constitutes a strategic movement by an armed force around the side, or flank, of an opposing enemy force. The primary objective is to achieve a position of superior advantage relative to the adversary.[1] This tactic leverages the inherent concentration of a force's combat strength along its front. By circumventing the enemy's primary defensive front and attacking its vulnerable flank, an attacking force can concentrate its offensive power where the enemy is least prepared to defend.

Scope of Application

The strategic implications of flanking extend beyond the immediate battlefield. Flanking maneuvers are not confined to tactical engagements but are also integral to the operational and strategic levels of warfare. Their effective execution can fundamentally alter the balance of power and dictate the overall course of a campaign or conflict.

Tactical Flanking

Ambush: The Surprise Assault

The first primary tactical maneuver is the ambush. This involves a unit executing a surprise attack from a concealed position. To enhance the effectiveness and achieve encirclement, allied units may be positioned to the sides of the ambush site. However, meticulous planning is required to manage fields of fire and prevent friendly fire incidents. Ambushes are typically favored by smaller, highly mobile forces operating in terrain conducive to concealment, such as exemplified by the Battle of Beaver Dams.

Direct Flank Attack: Pinning and Striking

The second tactical approach is employed when an attacking unit encounters an entrenched enemy defensive position. The strategy involves a portion of the attacking force engaging the enemy frontally to provide suppressive fire, thereby pinning the enemy and preventing them from reinforcing their flanks or retreating. Concurrently, a flanking force advances to attack the enemy's exposed side at close range. This method requires precise coordination to mitigate friendly fire and is often utilized by forces of comparable strength.

Double Envelopment: The Pincer Movement

The third, and often decisive, form of flanking maneuver is the double envelopment. This strategy entails simultaneous flanking attacks on both sides of the enemy formation. A classic illustration is Hannibal's masterful victory over the Roman army at the Battle of Cannae. This maneuver necessitates either significantly wider formations or gaps between units, which can weaken the center. It is most effectively employed when possessing numerical superiority or facing an opponent with insufficient cavalry support, as seen in battles like Gaugamela.

Maneuvering Through Eras

Pre-Modern Warfare

Historically, flanking maneuvers on land were predominantly executed by cavalry units, owing to their superior speed and mobility. These cavalry forces would typically flank the enemy, while heavily armored infantry would engage and pin the opposing front line. The Battle of Pharsalus serves as a notable example of this tactical paradigm.

The Age of Mechanization

With the advent of mechanized warfare in the 20th century, armored vehicles, particularly tanks, superseded cavalry as the primary instrument for executing flanking maneuvers. The Battle of France during World War II vividly demonstrated the transformative impact of armored thrusts in achieving strategic envelopment.

Defending Against the Flank

Leveraging Terrain

A fundamental aspect of defense against flanking involves the strategic utilization of terrain. Commanders can mitigate the risk of being outflanked by anchoring their lines on natural obstacles such as gorges, lakes, or mountainous regions, rendering them impassable to enemy forces. Historical instances include the Spartans at the Battle of Thermopylae and Hannibal at the Battle of Lake Trasimene. Even less formidable terrain, like woods or rivers, can serve to anchor a flank, though vigilance through skirmishers remains crucial.

Fortification and Prepared Positions

In certain circumstances, a flank may be secured by a fortified position, such as a castle or fortress. It is imperative, however, to establish a "killing space" between the fortress and the main battle line, allowing the garrison to engage enemy forces attempting to flank the field army. Natural strongholds can also be integrated into defensive lines, as seen at the Battle of Gettysburg with positions like Culp's Hill and Little Round Top. When time permits, field fortifications can be constructed or expanded to bolster flank defenses, as observed at the Battle of Waterloo.

Formations and Unit Disposition

When terrain offers no inherent advantage, the disposition of forces within the battle line becomes paramount. Traditionally, cavalry was positioned on the flanks of infantry formations due to their tactical flexibility, enabling both offensive flanking attacks and defensive screening. In the absence of effective cavalry, infantry units were trained to rapidly adopt defensive formations, such as squares, to present no vulnerable flank to enemy cavalry. The adoption of formations like the echelon formation or the oblique order, which concentrate strength on one flank to overwhelm a portion of the enemy line, also reflects the critical importance of flank security and exploitation.

Operational Flanking

Enveloping Entire Armies

At the operational level, commanders aim to flank and outmaneuver entire enemy armies, extending beyond tactical engagements. A prominent historical example is the modified Schlieffen Plan employed by Germany in World War I, which sought to bypass French frontal defenses by advancing through neutral Belgium. Such operations can be decisive, as demonstrated by the Battle of Inchon, or serve to relieve pressure on main fronts, as seen with the Anzio landings, by forcing the enemy to divert resources.

Opening Second Fronts

Similar to tactical defense, operational planning involves anchoring flanks. The German Winter Line in Italy during World War II, secured by the Tyrrhenian and Adriatic Seas, exemplifies this. When front lines become stalemated, flanking attacks into less defended areas can be initiated to break the deadlock. Strategic objectives, such as the Invasion of Italy, the Gallipoli campaign, and the Normandy landings, represent large-scale flanking operations with profound strategic consequences.

Strategic Flanking

Geopolitical Encirclement

On a strategic level, flanking manifests as a nation or coalition surrounding an adversary from multiple directions, forcing them to contend with threats on several fronts simultaneously. The Allied strategy against Nazi Germany in World War II is a prime example. This strategic posture can create significant disadvantages for the flanked nation.

Peacetime Maneuvers

The threat of strategic flanking profoundly influences geopolitical actions even during peacetime. The historical Great Game between the British and Russian Empires saw both powers expand their influence to avoid encirclement, leading to territorial competition in regions like China and Southeast Asia. The cultivation of alliances, such as the Anglo-Japanese Alliance, served as a counterweight to perceived strategic threats. Similarly, the Cold War involved intense competition between the US and USSR for global influence, employing proxy wars and crises like the Cuban Missile Crisis to gain strategic advantage.

Historical Examples

Ancient and Medieval Conflicts

The principles of flanking have been applied throughout military history. Ancient strategists like Hannibal utilized double envelopments, as at the Battle of Cannae. Miltiades's deployment at the Battle of Marathon demonstrates the importance of flank strength. In medieval and early modern periods, the use of cavalry for flanking remained critical, as seen in battles like Agincourt and the strategic maneuvers employed by Scipio Africanus against Carthage.

Modern and Contemporary Warfare

The 20th century saw flanking maneuvers evolve with the introduction of mechanized forces. The Battle of France showcased the power of armored breakthroughs. World Wars I and II featured large-scale operational flanking attempts, such as the Schlieffen Plan and the Allied encirclement of Germany. Amphibious landings like Normandy and Gallipoli represent strategic flanking operations aimed at opening new fronts and relieving pressure on existing ones.
