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.
The Gorham family (from Cape Cod) had a distinguished history in the New England colonial military. Serving alongside the early colonial military innovator Benjamin Church, John Gorham I died while fighting in the famous Great Swamp Fight during King Philip's War. Joseph's grandfather, John Gorham II, also served with Church during the fourth Eastward Expedition into Acadia, which involved the Raid on Chignecto (1696) during King William's War and again during Queen Anne's War. His father Shubael Gorham was also a provincial military officer in Queen Anne's War and again in King George's War. Joseph and his brother John Gorham III fought as rangers in Acadia/Nova Scotia throughout the 1740s as well as at the Siege of Louisbourg (1745) as officers in the Massachusetts provincial forces.
Joseph served as a lieutenant in his brother's ranger company from 1744 through 1752. Initially the rank and file members of the company were Wampanoag and Nauset Indians from southeastern Massachusetts, prized as much for their small-boat handling skills (learned in the whaling industry) as for their scouting and tracking skills, and also a handful of Pequawket Indians from Maine. Gorham was in the Battle at Canso during Father Le Loutre's War (1748-1752). Shortly after his brother's death in December 1751, Joseph was promoted to captain and took command of the rangers, who were by then mostly Anglo-Americans. During the French and Indian War he participated in the Expulsion of the Acadians and in both the Battle of Petitcodiac, where he was wounded, as well as the Cape Sable Campaign and the St. John River Campaign.
