North America Colonial Wars

In the mid 17th century the Colonists of New France were in conflict with the Iroquois Confederacy. Iroquois forces used hit and run tactics, harassment and avoided costly pitched battles. The colonists of New France began calling these Indian tactics La Petite Guerre because the tactics were meant for raiding as opposed to pitched battles. Under the tutelage of Wendake, Wobanaki, Algonquin and Ottawa tutors the habitants of New France learned La Petite Guerre and successfully used them against the Iroquois. In the early to mid 18th century Canadiens and Indian allies brought La Petite Guerre to New England and the Ohio Valley. Led by Major Benjamin Church, New Englanders had also been adopting Indian scouting and raiding tactics since King Phillips War. In Nova Scotia

In a different sense, the imperial command that the Russian serfs should attack the French resembled guerrilla tactics in its reliance on partisans rather than army regulars.

  • "It is manifest that, though a great army may easily defeat or disperse another army, less or greater, yet it is not in a like degree formidable to a determined people, nor efficient in a like degree to subdue them, or to keep them in subjugation–much less if this people, like those of Spain in the present instance, be numerous, and, like them, inhabit a territory extensive and strong by nature. For a great army, and even several great armies, cannot accomplish this by marching about the country, unbroken, but each must split itself into many portions, and the several detachments become weak accordingly, not merely as they are small in size, but because the soldiery, acting thus, necessarily relinquish much of that part of their superiority, which lies in what may be called the engineer of war; and far more, because they lose, in proportion as they are broken, the power of profiting by the military skill of the Commanders, or by their own military habits. The experienced soldier is thus brought down nearer to the plain ground of the inexperienced, man to the level of man: and it is then, that the truly brave man rises, the man of good hopes and purposes; and superiority in moral brings with it superiority in physical power." (William Wordsworth: Selected Prose, Penguin Classics 1988, page 177-8.)

 followed the patterns of irregular warfare in 19th century Europe. Structurally, irregular warfare can be divided into three different types conducted during the Civil War: 'People's War', 'partisan warfare', and 'raiding warfare'. The concept of 'People's war,' first described by Clausewitz in On War, was the closest example of a mass guerrilla movement in the era. In general, this type of irregular warfare was conducted in the hinterland of the Border States (Missouri, Arkansas, Tennessee, Kentucky, and northwestern Virginia), and was marked by a vicious neighbor against neighbor quality. One such example was the opposing irregular forces operating in Missouri and northern Arkansas from 1862 to 1865, most of which were pro-Confederate

Dozens of other small, localized bands terrorized the countryside throughout the border region during the war, bringing total war to the area that lasted until the end of the Civil War and, in some areas, beyond.

Partisan warfare, in contrast, more closely resembles Commando operations of the 20th century. Partisans were small units of conventional forces, controlled and organized by a military force for operations behind enemy lines. The 1862 Partisan Ranger Act

Not only did SOE help the resistance to tie down many German units as garrison troops, so directly aiding the conventional war effort, but also guerrilla incidents in occupied countries were useful in the propaganda war, helping to repudiate German claims that the occupied countries were pacified and broadly on the side of the Germans. Despite these minor successes, many historians believe that the efficacy of the European resistance movements has been greatly exaggerated in popular novels, films and other media.

 is commonly thought of as a guerrilla war. However, this is a simplification of a much more complex situation which followed the pattern outlined by Maoist theory.

The National Liberation Front (NLF), drawing its ranks from the South Vietnamese peasantry and working class, used guerrilla tactics in the early phases of the war. However, by 1965 when U.S. involvement escalated, the National Liberation Front was in the process of being supplanted by regular units of the North Vietnamese Army.

 in 1975 was a mostly conventional military operation in which guerrilla warfare played a minor, supporting role.

The Cu Chi Tunnels (Ðịa đạo Củ Chi) was a major base for guerrilla warfare during the Vietnam War. Located about 60 km northwest of Saigon (Ho Chi Minh City), the Viet Cong (NLF) used the complex system tunnels to hide and live during the day and come up to fight at night.

Despite the aggressiveness of the Vietnamese forces, the VietCong failed to achieve their objective. The defeat of the VietCong outlined the flaws of large scale guerrilla warfare over an extended time. These lessons were later exploited by SAS and Delta Force units during the Gulf War who worked in small teams instead of armies.

Throughout the Vietnam War, the Communist Party closely supervised all levels of the conflict. The bulk of the VC/NLF were initially southerners, with some distinctive southern issues and sensibilities. Nevertheless, the VC/NLF was associated with the Northern Lao Dong Party which furnished it with supplies, weaponry and trained cadres, including regular NVA/PAVN troops. The Southern Communist party, the Peoples Revolutionary Party (PRP) organized in 1962, to participate in the insurgency, and COVSN, Central Office for Southern Vietnam, which partially controlled military activity. The general replacement of CV irregulars with NVA troops supplanted the original VC goals with those proposed by the NVA. As the 1968 Tet Offensive was primarily a VC operation in which large numbers of VC fighters were killed, increasing the role of the NVA in the war effort.

This is a set of tactics which were used frequently in the Vietnam War by the NVA.
