Rogers' Rangers began in 1755 as a company in the provincial forces of the colony of New Hampshire in British North America. It was the latest in a long line of New England ranger companies dating back to the 1670s. The immediate precursor and model for the unit was Gorham's Rangers, formed in 1744. Both were initially organized by William Shirley. Gorham's Rangers are always depicted as precursors of Rogers' Rangers; however, they were also active throughout the French and Indian War, which makes them contemporaries of Rogers' Rangers. In fact, the Nova Scotia ranger corps that Gorham's company belonged to operated in cooperation with units of Rogers' corps on several occasions, most notably when Moses Hazen's company joined Rogers' Rangers at the Siege of Louisburg in 1758 and the Siege of Quebec in 1759. Rogers' company was formed to fight in the French and Indian War (the Seven Years' War in Canada, Britain, and Europe) in the borderlands of the colonial Northeast. They were commanded by Captain (later Major) Robert Rogers and operated primarily in the Lake George and Lake Champlain regions of New York. The unit was formed during the winter of 1755 from forces stationed at Fort William Henry. The Rangers sometimes undertook raids against French towns and military emplacements, traveling on foot, in whaleboats, and even on snowshoes during winter. Israel Putnam (who would go on to later fame in the Revolutionary War) fought as a Connecticut militia captain in conjunction with Rogers, and at one point saved his life.
