Caleb Gibbs (1748–1818) was the first commander of the Commander-in-Chief's Guard, the unit that protected General George Washington during the American Revolutionary War.
During the American Revolutionary War, Gibbs was appointed as the adjutant of the 14th Continental Regiment, commanded by Colonel John Glover of Marblehead, on January 1, 1776.
During his command of Washington's "Life Guard" Gibbs was promoted to the rank of Major on July 29, 1778.
In 1798 Gibbs was recommended by then retired Major General Henry Knox to command a regiment when the U.S. Army was expanded during the Quasi War with France.
Knox said of Gibbs - "No officer of the late American army would discipline and command a regiment with greater effect."
