The Indian method of warfare in the forest, perforce adopted by the white man also, was the most significant influence in developing and preserving the spirit of individualism and self-reliance in the military sphere. When the white man came, the Indian relied on bow and spear, or tomahawk and knife, but he soon learned the value of the white man's muskets and was not long in obtaining them in trade for his valuable furs. With bow or musket, his method of fighting was the same. Indian tribes had no organized system of war; warriors simply formed voluntary bands under war chiefs and took off on the warpath. In battle each Indian fought a separate opponent without regard for his fellows. Indians avoided pitched battle whenever possible, instead seeking victory by surprise and carefully utilizing cover and concealment. Only when they had the advantage did they close in for hand-to-hand combat. In such combat the Indian brave lacked neither skill nor courage. Since he cared little about the rules of civilized warfare, he slaughtered men, women, and children indiscriminately. The favorite Indian tactic was a surprise raid on an isolated settlement. When the settlers organized a pursuit, the Indians lay in wait and ambushed them.
The white man soon adapted his tactics to the Indian's, quickly learning the value of surprise and stealth himself. To avoid ambush he sent out scouts as the Indians did, frequently employing friendly Indians in the role. Instead of fighting in the closed formations of Europe, he too adopted the open formation and fought from behind trees, rocks, and fences. In such fighting more depended on individual initiative and courage than on strict discipline and control.
The white settler learned to benefit from some of the enemy's weaknesses. For all their cunning, the Indians never learned the lesson of proper security and did not post guards at night. Nor did they like to fight in winter. Expeditions into the Indian country used as their favorite technique an attack on an Indian village at dawn and in the winter season. This attack almost invariably came as a surprise, and the white man, imitating the savagery of his opponent, burned the Indian's villages and sometimes slaughtered braves, squaws, and papooses.
The settlers tried to provide some permanent protection for their frontiers by erecting forts along the western most line of settlement in each colony, moving them forward as the line of settlement moved. These forts were not the elaborate earth and masonry structures of Europe, but simple rectangular enclosures, their walls constructed of upright pointed logs. Usually there were wooden blockhouses at each corner. These rude frontier forts served as points to which settlers and their families could retreat for protection in time of Indian troubles. Having no artillery, the Indians found the forts hard to take and could rely only on burning arrows to set them afire, on surprise attack, or on direct frontal assault. From the last alternative they almost invariably shrank. Their war chiefs possessed no power to order any group of braves to undertake an assault in which they would suffer heavy casualties for the sake of gaining an objective.
For fighting Indians, colonial governments were in no position to form professional armies, even had the nature of Indian warfare lent itself to such a practice. Instead they fell back on the ancient British tradition of the militia. This tradition took on new vitality in America at the same time that it was declining in England where, after Oliver Cromwell's time, England's wars were fought on the sea and in foreign lands. The British Government came to rely on its Regular Army and Navy just as other European states did despite a continuing tradition of opposition to a standing army. Each of the thirteen colonies, except for Pennsylvania where Quaker influence was dominant, enacted laws providing for a compulsory militia organization, generally based on the principle of the Saxon fyrd that every able-bodied free male from sixteen to sixty should render military service. Each member of the militia was obligated to appear for training at his county or town seat a certain number of days each year, to provide himself with weapons, and to hold himself in readiness for call in case of Indian attack or other emergency.
Each colony maintained its separate militia establishment, and each concentrated on the problems of protecting or extending its own frontiers; co-operation among the militias of the various colonies was confined to specific expeditions in which two or more colonies had an interest. The militia was by and large a local institution, administered in county and town or township under the general militia laws of each colony. It was closely integrated with the social and economic structure of colonial society. Though the royal governors or colonial assemblies appointed the general officers and the colonels who commanded militia districts, the companies in each locality elected their own officers. This practice seemingly put a premium on popularity rather than wealth or ability, but rank in the militia generally corresponded with social station in the community.
Each individual militiaman was expected to provide his own weapon - usually a smoothbore musket - and ammunition, clothing, and food for a short expedition, just as the British knight had been required to provide his own horse, armor, and suitable weapons for feudal warfare. Local authorities maintained reserve supplies of muskets to arm those too poor to buy them and collected stores of ammunition and sometimes small cannon that could be dragged along through the wilderness. For really long campaigns, the colonial government had to take charge, the assembly appropriating the money for supplies and designating the supply officers or contractors to handle purchasing and distribution.
Although the militia was organized into units by county or township, it hardly ever fought that way. Instead the local unit served as a training and mobilization base from which individuals could be selected for active operations. When a particular area of a colony was threatened, the colonial government would direct the local militia commander to call out his men and the commander would mobilize as many as he could or as he thought necessary, selecting the younger and more active men for service. For expeditions into the Indian country, individuals from many localities were usually selected and formed into improvised units for the occasion. Selection was generally by volunteering, but local commanders could draft both men and property if necessary. Drafted men were permitted the option of hiring substitutes, a practice that favored the well to do. Volunteer, drafted man, and substitue alike insisted on the militiaman's prerogative to serve only a short period and return to home and fireside as quickly as possible.
As a part-time citizen army, the militia was naturally not a well-disciplined, cohesive force comparable to the professional army of the age. Moreover, its efficiency, even for Indian fighting, varied from colony to colony and even from locality to locality within the same colony, depending on the ability and determination of commanders and the presence or absence of any threat. When engaged in eliminating an Indian threat to their own community, militiamen might be counted on to make up in enthusiasm what they lacked in discipline and formal training, but when the Indian threat was pushed westward there was a tendency for people along the seaboard to relax. Training days, one a week in the early days of settlement, fell to one a month or even one a year. Festivities rather than military training increasingly became the main purpose of many of the gatherings, and the efficiency of the militia in these regions declined accordingly. In some towns and counties, however, the military tradition was kept alive by volunteers who formed units of their own, purchased distinctive uniforms, and prepared themselves to respond in case of war or emergency. These units became known as the volunteer militia and were the predecessors of the National Guard of the United States. In Pennsylvania, which lacked a militia law until 1755 and then passed one that made militia service voluntary rather than compulsory, all units were composed of volunteers.
On the frontier, where Indian raids were a constant threat, training days were more frequent and militia had to be ready for instant action. Except on the frontier, where proficiency in this sort of warfare was a matter of survival, it is doubtful that colonial militia in general were really adept in forest fighting. Training days were devoted not to the techniques of fighting Indians but to learning the drill and motions required on a European battlefield.
As early as the the 1630's during the Pequot War in New England, temporary detachments were drawn from the militia companies for field operations against the Indians. Volunteers or drafted quotas formed the detachments. This expedient practice minimized economic dislocation and concentrated field leadership in the hands of the most experienced officers. But even the detachments were seen as disrupting continuity life too much, and eventually they were employed primarily as garrisons. A different type of force emerged in the 1670's. Hired volunteers ranged the frontiers, patrolling between outposts and giving early warning of any Indian attack. Other volunteers combined with friendly Indians for offensive operations deep in the wilderness where European tactics were ineffective. The memoirs of the most successful leader of these mixed forces, Benjamin Church, were published by his son Thomas in 1716 and represent the first American military manual.
