Samuel McClellan (4 January 1730 – 17 October 1807) was a Brigadier General in the American Revolutionary War. He was born in Worcester, Massachusetts, married Jemina Chandler(1734-1764) on 16 November 1757 in Killingly, Connecticut, and Rachel Abbe (a descendant of Plymouth, Massachusetts Governor, William Bradford) on March 5, 1766, and is buried in Woodstock, Connecticut.
Samuel McClellan served as Ensign and Lieutenant in the French and Indian War, and was wounded in battle. Upon his return from the provincial campaign, he purchased a farm in Woodstock and settled there. He later engaged in mercantile business and established an extensive trade, importing goods and supplying neighboring merchants.
When the American Revolution put a stop to his trade, he trained and equipped the county militia. In 1773, a troop of horse was raised in Woodstock, Killingly, and Pomfret, Connecticut, of which he became commander.
In 1775, Major Samuel McClellan led 184 men at the Battles of Lexington and Concord. He played a prominent role in the Battle of Bunker Hill, and after achieving the rank of Lieutenant Colonel in 1776, Colonel in 1777, and Brigadier General of the 5th Brigade in 1779, his regiment of the Connecticut Militia was stationed near New Jersey. McClellan was solicited by General George Washington to join the Continental Army and was offered a commission, but his domestic and business affairs compelled him to refuse.
After the Battle of Groton Heights, and the invasion and burning of New London, Connecticut, McClellan was appointed to oversee troops stationed at those points and continued the command until the close of the war, acting as commissary in the purchase and forwarding of provisions for the army when not otherwise in active service.
McClellan was highly esteemed as a Christian gentleman and was well respected by his townsmen. Shortly after the war, he returned to Woodstock and was elected to the State Assembly. He was known to many, including his great-grandson George B. McClellan (a Major General during the American Civil War), as "General Sam." Samuel's sons James and John founded the Woodstock Academy in 1801.
