<P> Led by Major Benjamin Church, New Englanders had also been adopting Indian scouting and raiding tactics since King Philip's War . Throughout the four French and Indian Wars, starting in the late 17th century Canadiens, the Wabanaki Confederacy, and some Acadians brought La Petite Guerre to New England and the Ohio Valley . In present - day Maine, Father Sebastian Rale led the Wabanaki Confederacy in a petite guerre along the New England / Acadia border . A generation later, in Nova Scotia, Father Jean - Louis Le Loutre led the Mi'kmaq and the Acadians in a petite guerre behind Anglo - American lines in the lead up to the last French and Indian War . </P> <P> During the French and Indian War La Petite Guerre came to front stage when the Ohio valley Indians defeated Braddock's expedition near the forks of the Ohio in the Battle of the Monongahela . In Nova Scotia, French Officer Charles Deschamps de Boishébert led the Mi'kmaq and the Acadians in a guerrilla war while the British expelled the Acadians from the region . In the Northeast, a New Hampshire backwoodsman, Robert Rogers, began to make a stir in the British military establishment for his success using the tactics of the "little war". British military leaders like Jeffery Amherst, John Forbes and Henry Bouquet understood they needed to learn and adopt the techniques and tactics of the little war, or be consumed, like Braddock . The British military establishment began adopting some of the tactics of La Petite Guerre as "light infantry ." </P> <P> Although many of the engagements of the American Revolution were conventional, guerrilla warfare was used to a certain extent during this conflict from 1775--1783, which made a significant impact . Guerrilla tactics were first used at the Battles of Lexington and Concord by the Patriots at April 19, 1775 . George Washington sometimes used some sort of unconventional methods to fight the British . During the Forage War, George Washington sent militia units with limited Continental Army support to launch raids and ambushes on British detachments and forage parties, the militia and Continental Army support would skirmish with British detachments in small scale battles and engagements . Throughout the Forage War, British casualties exceeded past 900 . The Forage War raised morale for the Patriots as their guerrilla operations against the British were very effective . Next, there are other Americans that used hit and run raids, ambushes, and surprise attacks against the British such as William R. Davie, David Wooster, Francis Marion, Shadrach Inman, Daniel Morgan, Morgan's riflemen, and the Overmountain Men . All these American guerrilla fighters did their part by using unconventional tactics to fight the British and loyalists . Nathanael Greene used a guerrilla strategy very effectively against Lord Cornwallis . First, Nathanael Greene would keep retreating to lure the British far from their supply lines, then send out his forces to fight in small skirmishes and engagements with British detachments to weaken them . Then fighting the conventional battle, Nathanael Greene fought Lord Cornwallis at Guilford Court House and gave him a severe blow . Although Lord Cornwallis was the victor, his victory was pyrrhic as he had too many casualties that he could ill afford . After the British surrender at Yorktown and America gaining their independence, many of these Americans who used guerrilla tactics and strategies became immortalized and romanticized as time passed . Although guerrilla warfare was frequently used when avoiding battles, the Americans fought in conventional linear formations in decisive battles against the British . The American Revolution could be seen as a hybrid war since both conventional and guerrilla warfare were used throughout its duration . </P> <P> From 1793--1796 a revolt broke out against the French Revolution by Catholic royalists in the Department of the Vendée . This movement was intended to oppose the persecution endured by the Roman Catholic Church in revolutionary France (see Dechristianisation of France during the French Revolution #The Revolution and the Church) and ultimately to restore the monarchy . Though ill - equipped and untrained in conventional military tactics, the Vendéan counter-revolution, known as the "Royal Catholic Army," relied heavily on guerrilla tactics, taking full advantage of their intimate knowledge of the marsh filled, heavily forested countryside . Though the Revolt in the Vendée was eventually "pacified" by government troops, their successes against the larger, better equipped republican army were notable . </P>
