The position of the Adjutant dates back to Roman times. The Roman "ADJUTARE" was a key advisor who assisted the commander in battle. Since these ancient times, commanders throughout history have relied and depended on their adjutants to dispatch and carry out their orders.
On June 16, 1775, the Continental Congress decreed that there be an Adjutant General in the Continental Army, similar to such positions in the French and British Armies of that day. Congress appointed Horatio Gates, a former British Army Major, as the first Adjutant General on June 17, 1175, and commissioned him in the grade of Brigadier General. General Gates was the second officer to receive a commission in the Continental Army; George Washington was the first. General Gates proved himself to be an able assistant to General Washington as well as a brilliant field commander. Following his strategic victory over the British at Saratoga on October 17, 1777, the Congress awarded General Gates our country's highest honor, the Congressional Gold Medal. Today the Adjutant General's Corps recognizes members of its ranks for exceptionally meritorious service by inducting them into the Order of Horatio Gates and awarding them an official replica of Horatio Gates' Gold Medal.
During the war of 1812, Adjutants General proved themselves to be officers of exceptional character, judgement, and combat prowess. Among these heroes were: Winfield Scott at the Battle of Fort George, Pendleton Gaines for his defense of Fort Erie, Alexander Macomb for repulsing the British in the Battle of Plattsburg, and the famous explorer, Zebulon Pike, killed in battle while leading the victorious assault on York, Canada.
Adjutants General became the only officers invested with the authority to speak for the commander. Recognizing this, the Army began appointing West Point graduates almost exclusively as Adjutants General from 1838 through the early 1900's. The first two graduates so appointed, Samuel Cooper and Lorenzo Thomas, served with distinction as Adjutants General during the Civil War. Cooper served the South, and Thomas served the North.
The unique branch insignia of the Adjutants General's Corps became our official symbol on December 14, 1872. The shield was previously used by the Topographic Engineers as an authentication device on military maps. Thirteen embossed stars replaced the letters T.E. thus creating the branch insignia worn by all Adjutants General's Corps soldiers today. The insignia symbolizes the trust placed in the branch by the Army as representing the values of the nation and the authority to speak "For the Commander."
For more than 200 years the mission of the Adjutant General's Corps has remained constant and clear: to assist the commander in war and peace, and be the vanguard of personnel supprt to the Army. Today, through the unflagging dedication of our soldiers, the Corps continues to develop new and better means of providing quality service support. Our pride in the past is only surpassed by our optimism for the future. We are prepared to Defend and Serve!
