Did American colonist soldiers learn guerrilla fighting tactics from the Native Americans?

A Prussian soldier named Friedrich Wilhelm Ludolf Gerhard Augustin von Steuben is credited with turning the early American colonists into a fighting army. He has been recognized as the Father of our military. He was also gay. "Killing England" Bill O'Reilly.

Yes, many of them did. Specifically the third of four groups listed below. But that is not what finally won the war.

There were actually four groups of American soldiers. The first group was the smallest, numbering about 10,000, who were both trained and experienced. These men had marched and fought with George Washington in the first two years of the war, camped with him at Valley Forge in the winter of 1777-78, and were trained in marching and bayonet fighting there by (mostly) European officers such as (US-commissioned) General Friedrich Wilhelm von Steuben from Prussia. Naturally good at loading and shooting, these men were better than any in the British army.

The second group of men were subsequent regular recruits, who were trained but not experienced. They were put through similar training, but did not have the prior experience of the first group.

The third, and perhaps largest group, were men that were not formally trained by the regular army like the first two groups, but had military experience, usually fighting Native Americans. An example were the so-called "Overmountain Men", drawn from the mountainous areas at the borders of the modern Virginia/Kentucky, North Carolina/Tennessee, who fought the Cherokees. Such men formed irregular units that won notable battles at Kings Mountain and elsewhere in the South using guerrilla tactics. Some such units fought in northern battles such as the siege of Boston and Saratoga under officers such as Dan Morgan who taught them to target officers, "aim for the epaulette boys".

And the fourth group of men were raw militia, who did not have either the training or the experience of the first three groups. Such men were almost useless, although they did "pad the rolls" on the American side at a number of battles, notably Camden, South Carolina.

It is worth noting that men that got most of their experience by "learning" guerrilla tactics from Indians (through opposing them) were not as good as trained "regular" troops, except in special circumstances (like fighting from cover). Even so, they were decidedly better than militia with no experience, and thereby formed a pool of men that gave the British unexpected difficulties. It was not that their "flexible" guerrilla tactics usually led to victory. Instead they lost battles at a lower-than-expected rate until help arrived from Europe beginning in late 1777, or early 1778. Put another way, such men "beat the spread."

It is important to note that the American Revolution was finally won at e.g. Yorktown by trained troops, both "native" recruits in the first two groups, and the ones we received from France.

Yes, American colonist soldiers did learn guerrilla fighting tactics from the Native Americans.

One can believe that the Native Americans had a great influence on how warfare was shaped from the European methods of fighting as was done by soldiers in say France or England.

When Europeans first arrived and the inevitable conflicts with the Indians began, the Europeans were surprised and shocked by the Indian way of making war. Instead of the lines of infantry on open battlefields the Europeans were used to, the Indians used stealth, camouflage, surprise, deception, and other small-unit tactics that utilized the terrain as cover and confused their conventional European opponents. The European colonists quickly adapted and became every bit as skilled and savage as the Indians in waging frontier war and began using Indian tactics when they fought each other. In short, the Indians were good because their environment and culture promoted armed combat as a necessary skill. From having to survive by matching wits against nature and wild game, to having to defend themselves against rival tribes, the North American Indians were some of the finest soldiers in the world by the time Columbus arrived. Those societies mentioned earlier that had perished by the fifteenth century did not seem to value warfare according to what archaeologists tell us. That may be a major reason they weren’t there.

Evidence of the Indians’ influence on the American military still is evident at Fort Benning, Georgia, where the United States Army Ranger School posts the standing orders of Robert Rogers. Rogers was a colonial militiaman who admired the Indian way of combat and built a unit that modeled itself after the Indians’ tactics. They traveled off-road, learned ambush and tracking tactics, and traveled light while garnishing their food from nature as them rapidly moved overland. They proved extremely effective against the French in the French-Indian War and subsequent units that fought for both British and American colonists also utilized tactics learned from the Indians by Rogers’ Rangers. - What Students Need to Know about the Frontier Wars.

What really is guerrilla warfare?

Guerrilla Warfare. Guerrilla warfare (the word guerrilla comes from the Spanish meaning “little war”) is often the means used by weaker nations or military organizations against a larger, stronger foe. Fought largely by independent, irregular bands, sometimes linked to regular forces, it is a warfare of harassment through surprise. It features the use of ambushes, hit‐and‐run raids, sabotage, and, on occasion, terrorism to wear down the enemy. Typically, a small guerrilla force seeks to concentrate its strength against the weaker portions of the enemy's forces, such as outposts or lines of communication and logistics, to strike suddenly, and then to disappear into the surrounding countryside. In the American experience, this type of warfare has been used since the French and Indian War (1754–63), when colonists adopted American Indian tactics to strike back against French forces and their Indian allies. Maj. Robert Rogers of Connecticut, considered a founder of the guerrilla tradition in America, organized Rogers's Royal American Rangers in 1756 and trained them to carry the war deep into enemy territory. His doctrine, published as Rogers’ Rules for Ranging (1757), is considered a classic and is still issued to all soldiers attending the school for U.S. Army Rangers (Fort Benning, Georgia).

Here is this excellent article on American Military History which is quite informative, yet too long to quote in its entirety. It is great read for those interested.

Don't believe everything you see on TV. Colonel Robert Rogers was the founder, in order, of Roger's Rangers during the Seven Years War, and then the Queen's Rangers and King's Rangers during the Revolutionary War. All of these units fought loyally on the British side as effective irregular troops.

While it is certainly true that the early American Settlers learned much from the native inhabitants about both fighting as irregulars and traveling about and living off the land, by the time of the Revolutionary War many American colonists, both Loyalists and Patriots, were accomplished and even distinguished in that regard.

Update - from the link to American Military History (courtesy of Ken Graham, pp 38-9):

.... The lessons of the debacle on the Monongahela, as the British properly understood, were not that regular forces or European methods were useless in America or that undisciplined American militia were superior to regular troops. They were rather that tactics and formations had to be adapted to terrain and the nature of the enemy and that regulars, when employed in the forest, would have to learn to travel faster and lighter and to take advantage of cover, concealment, and surprise as their enemies did. ...

Special companies, such as Maj. Robert Rogers’ Rangers, were recruited among skilled woodsmen in the colonies and placed in the regular British establishment. ....

The colonial wars also proved that only troops possessing the organization and discipline of regulars, whatever their tactics, could actually move on, seize, and hold objectives and thus achieve decisive results.
