Brigadier-General John Forbes (5 September 1707 – 11 March 1759) was a British Army officer. During the French and Indian War, he commanded the 1758 Forbes Expedition which occupied the French outpost of Fort Duquesne. This required the construction of a military trail known as the Forbes Road, which became an important route for settlement of the Western United States. Forbes died in Philadelphia and was buried in the chancel of Christ Church, Philadelphia.

Life
John Forbes was born in Dunfermline on 5 September 1707, youngest child of Colonel John Forbes, 1658–1707, who died several months before his birth, and Elizabeth Graham, daughter of an Edinburgh merchant. His uncle, Duncan Forbes, 3rd of Culloden (1644-1704), was a prominent supporter of William of Orange and obtained his brother John an army commission.
In 1701, Colonel Forbes purchased Pittencrieff Park, near Dunfermline, and it was here John grew up. He had five elder sisters, of whom little is known, and two older brothers; Arthur (1703-1757), who inherited the estate, and Hugh (1704-1760), who became a lawyer. All three of the Forbes brothers had problems with money; John borrowed large sums to pursue his military career, while Arthur ruined himself expanding Pittencrief, which was sold after his death.
Forbes married Anna Donald and had a daughter Anna.
Career
The Forbes family were prominent civic leaders in Inverness, who supported the succession of George I in 1714 and were political allies of the Campbell Dukes of Argyll. John's cousin Duncan Forbes, 5th of Culloden (1685-1747), became senior Scottish legal officer in 1737 and played a key role in suppressing the 1745 Jacobite Rising. These personal connections were essential; like many contemporaries, John was also a Freemason, another of the informal networks needed for a successful public career in this period.
Educated locally in Dunfermline, Forbes is thought to have studied medicine at Edinburgh University. In September 1729, he was appointed surgeon in the Royal Scots Greys, then based in Scotland. He remained with the regiment for the next 28 years but gave up his medical post in 1735, when he was commissioned as a cornet.
The long period of peace from 1713 to 1739 meant limited opportunities for promotion, while the commission purchase system worked against those like Forbes with little money. It was not until April 1742 he was promoted lieutenant, shortly before the regiment was posted to the Austrian Netherlands to fight in the War of the Austrian Succession. Forbes became aide-de-camp to James Campbell of Lawers, (1690-1745), colonel of the Scots Greys and commander of the Allied cavalry. He fought at Dettingen in June 1743 and in September 1744, purchased a commission as captain.
At Fontenoy in May 1745, Campbell sent Forbes with instructions to Brigadier General Ingoldsby on the Allied right, ordering him to attack a French redoubt whose fire was impeding their advance. One shot badly wounded Sir James, who was carried from the field; Forbes stayed with him after the Allies retreated and was taken prisoner. He was soon exchanged but Campbell died a few days later and Forbes' letters display genuine grief at his death.
Many viewed Fontenoy as a 'defeat snatched from the jaws of victory', and in the recriminations that followed, Ingoldsby was court-martialled. The grounds were his failure to comply with three separate orders to attack the French position, given by Campbell, Cumberland, the Allied commander, and Ligonier. Ingoldsby claimed he received conflicting instructions and attempted to blame Forbes, who testified at his trial. While he had some justification, any confusion was caused by Cumberland, not Forbes; in any case, this was not considered an adequate excuse and Ingoldsby was forced to resign.
The Forbes Expedition
The Treaty of Aix-la-Chapelle set up a commission to resolve territorial disputes between British and French colonies in North America, including the Ohio Country, French Acadia and Nova Scotia. Neither side was willing to make concessions, which led to the 1754-1763 French and Indian War; in 1755, an expedition under General Braddock to capture Fort Duquesne ended in a disastrous defeat.
When the global conflict known as the Seven Years' War began in 1756, James Campbell's nephew, the Earl of Loudoun, was appointed Commander-in-Chief, North America and Governor General of Virginia. In early 1757, Forbes was in Southern England, training a 'light company' of the Scots Greys for attacks on the French coast. In March, he was promoted colonel of the 17th Foot, part of a force of 5,400 sent to Nova Scotia for an attempt on Louisbourg.
Following the failure of the 1757 Louisbourg Expedition, Forbes was promoted Brigadier general in December 1757 and given command of another attack on Fort Duquesne. His force contained 1,400 regulars, 400 from the Royal American Regiment, commanded by the experienced Swiss mercenary, Lt-Colonel Henry Bouquet, along with 1,000 Scots who made up Montgomerie's Highlanders. There were also 5,000 provincial militia from Virginia and Pennsylvania, commanded by George Washington, who had carried messages to Fort Le Boeuf in 1753, and accompanied Braddock in 1755.
Forbes decided to build a new road from the Pennsylvania frontier, since it required fewer river crossings than that used by Braddock, which followed a trail cut in 1752 by the Virginia-based Ohio Company. The decision led to protests from his Virginian officers, many of whom were investors in the company, including two of Washington's brothers.
As a compromise, Forbes agreed to improve Braddock's original road, but use the route through Pennsylvania. A base was established at Carlisle, Pennsylvania, and a trail cut through the Allegheny Mountains, which became the Forbes Road. Already severely ill, Forbes had to be carried in a litter and relied heavily on Bouquet, who commanded the advance guard. Construction of the road and bases such as Fort Ligonier was supervised by Lt-Colonel John St Clair, who proved to be incompetent and required Forbes to do much of the work, despite his poor health.
Legacy
Forbes Field, now demolished but which formerly served as the home field for the Pittsburgh Pirates, Pittsburgh Steelers and the Pitt Panthers football team, was named after John Forbes. Forbes Field was America's first all-steel and concrete baseball stadium. Forbes Avenue, one of the city of Pittsburgh's principal boulevards, runs from the Monongahela River in Downtown Pittsburgh to Frick Park and the start of the eastern suburbs. It is named in his honor and roughly follows his colonial road. John Forbes Lane in Kanpur running from British India Corporation to Huddard High School is named in his memory.
