Horatio Gates

During the French and Indian War, Gates served General Edward Braddock in America. In 1755 he accompanied the ill-fated Braddock Expedition in its attempt to control access to the Ohio Valley. This force included other future Revolutionary War leaders such as Thomas Gage, Charles Lee, Daniel Morgan, and George Washington. Gates didn't see significant combat, since he was severely injured early in the action. His experience in the early years of the war was limited to commanding small companies, but he apparently became quite good at military administration. In 1759 he was made brigade major to Brigadier General John Stanwix, a position he continued when General Robert Monckton took over Stanwix's command in 1760.[5] Gates served under Monckton in the capture of Martinique in 1762, although he saw little combat. Monckton bestowed on him the honor of bringing news of the success to England, which brought him a promotion to major. The end of the war also brought an end to Gates' prospects for advancement, as the army was demobilized and he did not have the financial wherewithal to purchase commissions for higher ranks.[5]

In November 1755, Gates married Elizabeth Phillips and had a son, Robert, in 1758. Gates' military career stalled, as advancement in the British army required money or influence. Frustrated by the British class hierarchy, he sold his major's commission in 1769, and came to North America. In 1772 he reestablished contact with George Washington, and purchased a modest plantation in Virginia the following year.

When the word reached Gates of the outbreak of war in late May 1775, he rushed to Mount Vernon and offered his services to Washington. In June, the Continental Congress began organizing the Continental Army. In accepting command, Washington urged the appointment of Gates as adjutant of the army. On June 17, 1775, Congress commissioned Gates as a Brigadier General and Adjutant General of the Continental Army. He is considered to be the first Adjutant General of the United States Army.[6]

Gates's previous wartime service in administrative posts was invaluable to the fledgling army, as he and Charles Lee were the only men with significant experience in the British regular army. As adjutant, Horatio Gates created the army's system of records and orders and helped standardize regiments from the various colonies. During the siege of Boston, he was a voice of caution, speaking in war councils against what he saw as overly risky actions.[7]

Although his administrative skills were valuable, Gates longed for a field command. By June 1776, he had been promoted to Major General and given command of the Canadian Department to replace John Sullivan. This unit of the army was then in disorganized retreat from Quebec, following the arrival of British reinforcements at Quebec City. Furthermore, disease, especially smallpox, had taken a significant toll on the ranks, which also suffered from poor morale and dissension over pay and conditions. The retreat from Quebec to Fort Ticonderoga also brought Gates into conflict with the authority of Major General Philip Schuyler, commander of the army's Northern Department, which retained jurisdiction over Ticonderoga. During the summer of 1776, this struggle was resolved, with Schuyler given command of the department as a whole and Gates command of Ticonderoga and the defense of Lake Champlain.[8]

Gates spent the summer of 1776 overseeing the enlargement of the American fleet that would be needed to prevent the British from taking control of Lake Champlain. Much of this work eventually fell to Benedict Arnold, who had been with the army during its retreat and was also an experienced seaman. Gates rewarded Arnold's initiative by giving him command of the fleet when it sailed to meet the British. The American fleet was defeated at the Battle of Valcour Island in October 1776, although the defense of the lake was sufficient to delay a British advance against Ticonderoga until 1777.[9]

When it was clear that the British were not going to make an attempt on Ticonderoga in 1776, Gates marched some of the army south to join Washington's army in Pennsylvania, where it had retreated after the fall of New York City. Though his troops were with Washington at the Battle of Trenton, Gates was not. Always an advocate of defensive action, Gates argued that Washington should retreat further rather than attack. When Washington dismissed this advice, Gates claimed illness as an excuse not to join the nighttime attack and instead traveled on to Baltimore, where the Continental Congress was meeting. Gates had always maintained that he and not Washington should have commanded the Continental Army, an opinion supported by several wealthy and prominent New England delegates to the Continental Congress. Although Gates actively lobbied Congress for the appointment, Washington's stunning successes at Trenton and Princeton subsequently left no doubt as to who should be commander-in-chief. Gates was then sent back north with orders to assist Schuyler in the Northern Department.

But in 1777, Congress blamed Schuyler and St. Clair for the loss of Fort Ticonderoga, though Gates had exercised a lengthy command in the region. Congress finally gave Gates command of the Northern Department on August 4.

Gates assumed command of the Northern Department on August 19 and led the army during the defeat of British General Burgoyne's invasion in the Battles of Saratoga. While Gates and his supporters took credit for the victory, military action was directed by a cohort of field commanders led by Benedict Arnold, Enoch Poor, Benjamin Lincoln, and Daniel Morgan. Arnold in particular took the field against Gates' orders and rallied the troops in a furious attack on the British lines, suffering serious injuries to his leg. John Stark's defeat of a sizable British raiding force at the Battle of Bennington–Stark's forces killed or captured over 900 British soldiers–was also a substantial factor in the outcome at Saratoga.

Gates stands front and center in John Trumbull's painting of the Surrender of General Burgoyne at Saratoga,[10][11] which hangs in the U.S. Capitol Rotunda. By Congressional resolution, a gold medal was presented to Gates to commemorate his victories over the British in the Battles of Bennington, Fort Stanwix and Saratoga. Gold and bronze replicas of that medal are still awarded by the Adjutant General's Corps Regimental Association in recognition of outstanding service.[12]

Gates followed up the victory at Saratoga with a proposal to invade Quebec, but his suggestion was rejected by Washington.[13]

Gates attempted to maximize his political return on the victory, particularly as George Washington was having no present successes with the main army. In fact, Gates insulted Washington by sending reports directly to Congress instead of to Washington, his commanding officer. At the behest of Gates's friends and the delegates from New England, Congress named Gates to President of the Board of War, a post he filled while retaining his field command —an unprecedented conflict of interest. The post technically made Gates Washington's civilian superior, conflicting with his lower military rank. At this time, some members of Congress briefly considered replacing Washington with Gates as commander-in-chief, supported by military officers also in disagreement with Washington's leadership.

Washington learned of the campaign against him by Gates's adjutant, James Wilkinson. In a letter to Gates, Wilkinson forwarded remarks of General Thomas Conway critical of Washington to General William Alexander, who passed them on to Washington. Gates (then unaware of Wilkinson's involvement) accused persons unknown of copying his mail and forwarded Conway's letter to the president of Congress, Henry Laurens. Washington's supporters in Congress and the army rallied to his side, ending the "Conway Cabal".[14][15] Gates then apologized to Washington for his role in the affair, resigned from the Board of War, and took an assignment as commander of the Eastern Department in November 1778.

In May 1780, news of the fall of Charleston, South Carolina and the capture of General Benjamin Lincoln's southern army reached Congress.[16] It voted to place Gates in command of the Southern Department.[17] He learned of his new command at his home near Shepherdstown, Virginia (now West Virginia), and headed south to assume command of the remaining Continental forces near the Deep River in North Carolina on July 25, 1780.[18]

Gates led Continental forces and militia south and prepared to face the British forces of Charles Cornwallis, who had advanced to Camden, South Carolina. In the Battle of Camden on August 16, Gates's army was routed, with nearly 1,000 men captured, along with the army's baggage train and artillery. Analysis of the debacle suggests that Gates greatly overestimated the capabilities of his inexperienced militia, an error magnified when he lined those forces against the British right, traditional position of the strongest troops. He also failed to make proper arrangements for an organized retreat. Gates's principal accomplishment in the unsuccessful campaign was to cover 170 miles (270 km) in three days on horseback, heading north in retreat. His disappointment was compounded by news of his son Robert's death in combat in October. Nathanael Greene replaced Gates as commander on December 3, and Gates returned home to Virginia. Gates's devastating defeat at Camden not only ruined his new American army, but it also ruined his military reputation.

Because of the debacle at Camden, Congress passed a resolution calling for a board of inquiry, the prelude to a court-martial, to look into Gates's conduct. Always one to support a court-martial of other officers, particularly those with whom he was in competition for advancement, such as Benedict Arnold, Gates vehemently opposed the inquiry into his own conduct. Although he never was again placed in field command, Gates's New England supporters in Congress came to his aid in 1782, repealing the call for an inquiry. Gates then rejoined Washington's staff at Newburgh, New York. Rumors implicated some of his aides in the Newburgh Conspiracy of 1783. Gates may have agreed to involve himself, though this remains unclear.[19]
