Irregular Military - Historical Reliance On Irregulars

Historical Reliance On Irregulars

By definition, "irregular" is understood in contrast to "regular armies," which grew slowly from personal bodyguards or elite militia. In Ancient warfare, most civilized nations relied heavily on irregulars to augment their small regular army. Even in advanced civilizations, the irregulars commonly outnumbered the regular army.

Sometimes entire tribal armies of irregulars were brought in from internal native or neighboring cultures, especially ones that still had an active hunting tradition to provide the basic training of irregulars. The regulars would only provide the core military in the major battles; irregulars would provide all other combat duties.

Notable examples of regulars relying on irregulars include Bashi-bozouk units in the Ottoman Empire, auxiliary legions of Germanic tribes in the Roman Empire, Cossack regiments in Imperial Russia, and Native American forces in the far west of the Confederate States of America.

One could attribute the disastrous defeat of the Romans at the Battle of the Teutoburg Forest to the lack of supporting irregular forces; only a few squadrons of irregular light cavalry accompanied the invasion of Germany when normally the number of foederati legions would equal the regular legions; however, since irregulars won that battle, there are few surviving details.

During the decline of the Roman Empire, irregulars made up an ever increasing proportion of the Roman military. At the end, there was little difference between the Roman military and the barbarians across the borders. Throughout history, most civilizations eventually fell to "barbarians", that is, irregular military forces, with minimal historical details.

Following Napoleon's modernisation of warfare with the invention of conscription, the Peninsular War led by Spaniards against the French invaders in 1808 provided the first modern example of guerrilla warfare. Indeed, the term of guerrilla itself was coined during this time.

As the spread of industrialism dried up the traditional source of irregulars, nations were forced take over the duties of the irregulars using specially trained regular army units. Examples are the light infantry in the British Army.

Use of large irregular forces featured heavily in wars such as the American Revolution, the Irish War of Independence, the Franco-Prussian War, the Russian Civil War, the Second Boer War, Vietnam War, and especially the Eastern Front of World War II where hundreds of thousands of partisans fought on both sides.
