Hugh Mercer - Seven Years War

Seven Years War

Further information: Great Britain in the Seven Years War

In 1755, when General Edward Braddock's army was cut down by the French and Indians during the first British attempt to take Fort Duquesne, Mercer was shocked by the same butchery he remembered at Culloden. He came to the aid of the wounded and eventually took up arms in support of the army that a few years back was hunting him, this time as a soldier, not a surgeon. By 1756 he was commissioned a captain in a Pennsylvania regiment, and accompanied Lt. Col. John Armstrong's expedition on the raid of the Indian village of Kittanning in September 1756. During the attack, Mercer was badly wounded and separated from his unit. He trekked 100 miles through the woods for fourteen days, injured and with no supplies, until he found his way back to Fort Shirley, where he was recognized and promoted. He rose to the rank of colonel and commanded garrisons. It was during these trying times that Mercer developed a lifelong and warm friendship with another colonel, George Washington.

Both Washington and Mercer served under British General John Forbes during the second attempt to capture Fort Duquesne. Forbes occupied the burned fort on November 25, 1758. He immediately ordered the construction of a new fortification to be named Fort Pitt, after British Secretary of State William Pitt the Elder. He also named the settlement between the rivers "Pittsborough," which is the location of modern Pittsburgh, Pennsylvania.

Forbes’s health, which had been poor for much of the campaign, began a rapid decline during his occupation of Fort Pitt. On December 3, 1758, now gravely ill, Forbes began the arduous journey back to Philadelphia leaving Colonel Hugh Mercer in command of Fort Pitt. General Forbes died in Philadelphia on March 11, 1759. He was buried in Christ Church in Philadelphia.

Mercer's first task was to construct a temporary Fort to hold the Forks of the Ohio in case the French were able to execute their plans to return in the Spring of 1759. Drawing of the time call this temporary fortification "Mercer's Fort". Mercer's Fort stood at the site of what is today a parking lot between Point State Park and the Pittsburgh Post Gazette Building.

After befriending several Virginia men, Mercer moved to Fredericksburg, Virginia in 1760 to begin his medical practice anew at the conclusion of the war. When Mercer arrived in Fredericksburg, it was a thriving Scottish community that must have been a happy sanctuary for a Scotsman who could never again see his homeland. He became a noted member and businessman in town, buying land and involving himself in local trade. He became a member of the Fredericksburg Masonic Lodge in 1767, and sat as its Master a few years later. (Two members of this same lodge, Washington and James Monroe, would later become American Presidents, and at least eight members were generals of the American Revolution (Washington, Mercer, George Weedon, William Woodford, Fielding Lewis, Thomas Posey, Gustavus Wallace, and the Marquis de Lafayette (honorary in 1824) – far more than any other group, institution or organization save the pre-Revolution British Army. This lodge is still in existence today.)

Soon after this, Mercer opened a physician’s apothecary and practice. His apothecary in Fredericksburg, Virginia is now a museum. George Washington's mother, Mary Washington, became one of Mercer's patients, and Mercer prospered as a respected doctor in the area. Mercer married Isabella Gordon and fathered five children: Ann Mercer Patton, John Mercer, William Mercer, George Weedon Mercer, and Hugh Tennant Mercer. In 1774, George Washington sold Ferry Farm, his childhood home, to Mercer, who wanted to make this prized land into a town where he and his family would settle for the remainder of his days.

During 1775, Mercer was a member of the Fredericksburg Committee of Safety, and on April 25 he was one of the members of the Independent Company of the Town of Fredericksburg who sent a letter of concern to then-Colonel George Washington when the British removed gunpowder from the magazine at Williamsburg. In an August vote, Mercer was excluded from the elected leadership of the new regiments formed by the Virginia Convention because he was a "northern Briton," but on September 12 he was elected Colonel of the Minute Men of Spotsylvania, King George, Stafford, and Caroline Counties.

On November 17 Mercer was one of 21 members chosen for the Committee of Safety of Spotsylvania County. On January 11, 1776, Mercer was appointed Colonel to what soon became the 3rd Virginia Regiment of the Virginia Line, and the next day George Weedon was appointed Lieutenant Colonel. Future president James Monroe and future Chief Justice of the United States John Marshall also served as officers under his command. In June 1776 Mercer received a letter from the Continental Congress, signed by John Hancock, appointing him Brigadier-General in the Armies of the United Colonies and requesting him to report to headquarters in New York immediately. Mercer soon left Fredericksburg to join the Continental Army.
