Question: James Rogers served with what American colonial frontiersman, who was his brother, and who served in the British army during the French and Indian War, and the American revolution?
Context: Joseph Gorham (sometimes recorded as Goreham, 1725–1790) was an American colonial military officer during King George's War and later a British army commander during the Seven Years' War and the American Revolutionary War.  He is best known for leading a company of British imperial Rangers, called Gorham's Rangers, during the 1750s and early 1760s.  Gorham's unit played an important role in the French and Indian War and were early practitioners of American frontier warfare, more commonly known as "petite guerre" or Guerrilla warfare. James Rogers (c. 1726 – September 23, 1790) was an Irish-born soldier.  He emigrated to America at an early age and became a frontiersman.  He served with his brother Robert Rogers during the French and Indian War.  He then served as a Loyalist leader during the American War of Independence and later settled in Ontario in Canada. The Military history of North America can be viewed as having four distinct phases.  The first is the precolonial period, during which warfare and conquest occurred from time to time between Native American tribes and alliances.  The second is the colonial period following the European discovery of the continent, during which the region saw both European efforts to wrest territories from their native inhabitante, and where European nations used their North American colonial possessions to wage wars with one another for the control of resources.  This phase culminated in the American Revolution, with the continent thereafter shifting away from European military domination.  The third phase was one of internal discord on the continent, including skirmishes between the United States and Canada, the Mexican–American War, the American Civil War and similar internal violence in Mexico, the Indian Wars, and the expulsion of the last major colonial bastion in the Spanish–American War. John Ross (1744–1809) was a British Army officer in the French and Indian War and the American Revolution.  He is best known for commanding a mixed force of approximately 600 (some sources say 1750) regulars, Loyalists, and Indians in a raid into upstate New York on October 24, 1781 that culminated in the Battle of Johnstown, one of the last battles in the northern theater of the American Revolution.  After the war, Ross was instrumental in settling Loyalist refugees in what is now the Kingston area of eastern Ontario. Jonathan Eddy (c. 1726–1804) served for the British in the French and Indian War and for the American Patriots in the American Revolution.  After the French and Indian War he settled in Nova Scotia as a New England Planter, becoming a member of the General Assembly of Nova Scotia.  During the American Revolutionary War, he was strongly supportive of the rebellion against the Crown.  He encouraged the residents of Nova Scotia to join in open revolt against King George III and England.  He led a failed attempt to capture Fort Cumberland in 1776 and was forced to retreat to Massachusetts, the place of his birth.  The following year he led the defense of Machias, Maine during the Battle of Machias (1777).  After the war he established the community now known as Eddington, Maine in 1784, where he died. Provincial troops were raised by the colonial governors and legislatures for extended operations during the French and Indian Wars.  The provincial troops differed from the militia, in that it was a full-time military organization conducting extended operations; differing from the regular British Army in that it was recruited only for one campaign season at the time.  These forces were often recruited through a quota system applied to the militia.  The officers were appointed by the provincial governments.  During the eighteenth century militia service was increasingly seen as a prerogative of the social and economic well-established, while provincial troops came to be recruited from different and less deep-rooted members of the community.  The first provincial forces in British North America were organized in the 1670s.  The major operations during King William's War were conducted by provincial troops from Massachusetts Bay.  During Queen Anne's War provincial troops from Massachusetts Bay, Connecticut, and New Hampshire made up the bulk of the English forces.  During King George's War the land forces that took Louisbourg was entirely supplied by Massachusetts, Connecticut, New Hampshire, and Rhode Island.  During the French and Indian War the imperial government in London took an increasingly more leading part, relegating the provincial troops to a non-combat role, largely as pioneers and transportation troops, while the bulk of the fighting was done by the regular British Army.  However the contributions of Connecticut, Massachusetts Bay, New Hampshire, and Rhode Island were essential. Robert Rogers (7 November 1731 – 18 May 1795) was an American colonial frontiersman.  Rogers served in the British army during both the French and Indian War and the American Revolution.  During the French and Indian War, Rogers raised and commanded the famous Rogers' Rangers, trained for raiding and close combat behind enemy lines. John Stark (August 28, 1728 – May 8, 1822) was a New Hampshire native who served as an officer in the British Army during the French and Indian war and a major general in the Continental Army during the American Revolution.  He became widely known as the "Hero of Bennington" for his exemplary service at the Battle of Bennington in 1777. Benjamin Goldthwait was a British army officer who served in King George's War and the French and Indian War.  He fought in the Siege of Louisbourg (1745) (along with his brother Joseph).  He arrived in Annapolis Royal, Nova Scotia in 1746 and then fought in the Battle of Grand Pre.  He then fought during the French and Indian War in the Battle of Fort Beauséjour. Rogers' Rangers was initially a provincial company from the colony of New Hampshire, attached to the British Army during the Seven Years' War (called the French and Indian War in the United States).  The unit was quickly adopted into the British army as an independent ranger company.  It was trained by Major Robert Rogers as a rapidly deployed light infantry force tasked mainly with reconnaissance as well as conducting special operations against distant targets.  Their tactics were built on earlier colonial precedents and were codified for the first time by Rogers.  The tactics proved remarkably effective, so much so that the initial company was expanded into a ranging corps of more than a dozen companies (containing as many as 1,200–1,400 men at its peak).  The ranger corps became the chief scouting arm of British Crown forces by the late 1750s.  The British valued them highly for gathering intelligence about the enemy.
