How Important are Superior Numbers?: A Reappraisal of Lanchester's Square Law

During the American Civil War, the ratio of losses incurred was inversely proportional to the ratio of numbers effectively engaged, demonstrating that the numbers of fighting units in a military force are less important than the ability of those units to get into action and inflict losses on the enemy.

A century ago, Frederick Lanchester developed a mathematical model of combat that proposed that a military force's combat power was directly proportional to the product of the individual effectiveness of its units and the square of the number of units deployed. This model reinforced the belief in the significance of superior numbers, which had been prevalent for centuries. However, subsequent historical studies failed to establish a clear correlation between the numbers of opposing forces and the resulting losses.

In this Element, we examine American Civil War battles to demonstrate that the ratio of losses incurred was inversely proportional to the ratio of numbers effectively engaged. This finding challenges the notion that the sheer volume of troops is paramount, highlighting the importance of the units' ability to engage and inflict damage on the enemy.

This result sheds light on the limitations of the Square Law, which suggests that the combat power of a force increases with the square of the number of units. It emphasizes the need for a more nuanced understanding of warfare, where factors such as unit effectiveness, tactics, and strategy play a crucial role in determining military outcomes.

By recognizing the limitations of the Square Law, military leaders and policymakers can avoid making decisions based solely on the number of troops deployed. Instead, they should focus on developing strategies that maximize the efficiency and effectiveness of their forces, enabling them to achieve their objectives while minimizing casualties and losses.

In conclusion, the analysis of American Civil War battles highlights the importance of individual unit effectiveness and the limitations of the Square Law in determining military outcomes. It underscores the need for a more holistic approach to warfare that considers factors such as tactics, strategy, and the capabilities of the fighting units. By adopting such an approach, military organizations can enhance their effectiveness and achieve greater success on the battlefield.
