Dayton's military career
Jonathan Dayton was born on October 16, 1760, in Elizabethtown, New Jersey. His father, Elias Dayton, was a prominent merchant and militia officer in the French and Indian War, and was also active in local politics. Jonathan attended the local "Reeves" school, where his classmates included Alexander Hamilton and Aaron Burr. After graduating, Dayton attended the College of New Jersey (now Princeton University).
When the Revolutionary War broke out, Dayton enlisted and served under his father, who commanded the 3rd New Jersey Regiment. On January 1, 1777, he was commissioned a lieutenant and served as paymaster. Dayton saw service under General George Washington, fighting in the battles of Brandywine Creek and Germantown. He remained with Washington at Valley Forge and helped push the British from their position in New Jersey into the safety of New York City. In October 1780, Dayton and an uncle were captured by Loyalists, who held them captive for the winter before releasing them the following year. Dayton then served under his father again in the New Jersey Brigade. On March 30, 1780, at age 19, he was promoted to the rank of captain and transferred to the 2nd New Jersey Regiment, where he took part in the Battle of Yorktown.

Dayton's arrest and its impact on his career
Jonathan Dayton, the youngest person to sign the US Constitution, was arrested in 1807 for alleged treason in connection with Aaron Burr's conspiracy to establish an independent country in the Southwestern US and parts of Mexico. Although he was exonerated by a grand jury, the arrest marked a turning point in his political career, from which he was never able to recover.
Dayton's career before his arrest was illustrious, having served in the military during the Revolutionary War, fighting in the battles of Brandywine Creek and Germantown, and remaining with General George Washington at Valley Forge. After the war, he studied law and opened a practice, dividing his time between land speculation, law, and politics. He served as a New Jersey delegate to the Continental Congress and Constitutional Convention, and later became a prominent Federalist legislator, serving in the New Jersey General Assembly and the New Jersey Legislative Council. He was elected to the US House of Representatives in 1791 and served as its third speaker from 1795 to 1799. He was then elected to the US Senate, where he served one term from 1799 to 1805.
However, Dayton's arrest in 1807 changed the trajectory of his career. He was accused of being involved in Aaron Burr's conspiracy, later known as the Burr Conspiracy, to establish an independent country in the Southwestern United States and parts of Mexico. This was a serious charge of treason against the United States. Although he was exonerated by a grand jury, the accusation had a detrimental effect on his reputation and national political career.
After his arrest and exoneration, Dayton held public office only once more in his life, serving a term in the New Jersey legislature from 1814 to 1815. He spent most of his remaining years devoted to developing his large landholdings in Ohio. The city of Dayton, Ohio, was named after him, although he never visited the area.
