A Story of Service: Major General Henry Dearborn (1751–1829)

Henry Dearborn was born on February 23, 1751, in the small New Hampshire town of North Hampton, a child of colonial America on the brink of revolution. Trained as a physician, he might have spent his days tending to the sick and injured in rural New England. But fate—and principle—had other plans. When the first shots of the American Revolution rang out in April 1775, Dearborn left behind his medical practice to answer the call to arms. It would be the beginning of a lifetime dedicated to the service of his country.

As a captain in the 1st New Hampshire Regiment, Dearborn fought at the Battle of Bunker Hill, one of the Revolution’s first major clashes. Later that year, he joined Benedict Arnold’s grueling expedition through the Maine wilderness to launch an assault on Quebec. There, in a failed but heroic attack on New Year’s Eve 1775, Dearborn was captured by British forces. Held as a prisoner for nearly a year, he was eventually paroled and later exchanged, returning to the fight as a major in the Continental Army.

Dearborn’s Revolutionary War record is a chronicle of the struggle itself. He was at Ticonderoga during its controversial evacuation in 1777, and he distinguished himself at both battles of Saratoga—key victories that turned the tide of the war. He wintered with General Washington at Valley Forge, enduring the bitter cold and deprivation alongside the men he led. At Monmouth in 1778, he served with Washington again, and in 1779, he joined the Sullivan Expedition, which targeted British-allied Iroquois forces in the New York frontier.

By the war’s end, Dearborn had risen to the rank of lieutenant colonel and served at the Siege of Yorktown, where the British surrender effectively sealed American independence. After eight years of near-continuous military service, he was honorably discharged in June 1783.

Yet Dearborn’s service to the fledgling republic was far from over. In the 1790s, he was elected to Congress as a representative from Massachusetts, where he supported a stronger central government but remained wary of Federalist overreach. His political alignment with Thomas Jefferson would shape the next chapter of his career. When Jefferson became president, he named Dearborn as his Secretary of War—a position he held from 1801 to 1809. In that role, Dearborn oversaw the nation’s small standing army, helped organize the Lewis and Clark Expedition, and managed Native American relations during a period of western expansion.

In 1812, with the United States again at war—this time against Great Britain—President James Madison called on Dearborn once more. Though now in his sixties, Dearborn was appointed senior major general and commanding general of the U.S. Army. He led the American offensive into Upper Canada, capturing both York (now Toronto) and Fort George in 1813. While his performance was mixed and he faced political criticism, he remained a steady if cautious leader at a time when the young nation’s military was still taking shape.

After the war, Dearborn returned to civilian life, later serving as U.S. Minister to Portugal. He passed away on June 6, 1829, in Roxbury, Massachusetts, and was laid to rest at Forest Hills Cemetery in Boston.

From a frontier doctor to a revolutionary officer, a trusted cabinet secretary, and a wartime general, Henry Dearborn’s life was one of enduring service. His legacy endures in the town of Dearborn, Michigan—named in his honor—and in the annals of American history, where he stands as one of the Revolutionary generation who helped birth a nation and defend it in its infancy.
