George Brinton McClellan 

George Brinton McClellan was born in Philadelphia, Pennsylvania, 3 December, 1826.  He was educated by private tutors, and spent two years, 1840-42 at the University of Pennsylvania, where he was an industrious student and shared the first honors of his class. At the age of fifteen years and six months (the minimum age being sixteen, and the exceptions rare) he entered the United States Military Academy on July 1st, 1842.

At West Point, he led his class in mathematics. After graduating in July 1846, McClellan was appointed brevet 2d lieutenant in the corps of engineers, and assigned to a company of engineer troops (the only one then in service) raised for the Mexican war.

 

During that conflict, he was at Malan, Camargo, Tampico, and Vera Cruz. After the fall of Vera Cruz, he took an active part in the battle of Cerro Gordo, April 17-18, 1847, and the unsuccessful attack on the left against the triple batteries that swept the road. A second attack was rendered unnecessary by the fall of the Cerro de Telegrafe.

He was promoted to 2nd Lieutenant on April 24th, and took part in the battles of Contreras and Churubusco (August 18-19) and the assault and capture of the city of Mexico (September 13-14).  He received the brevet of 1st Lieutenant "for gallant and meritorious conduct at Contreras and Churubusco," and the brevet of Captain for his part in the assault of Chapultepec.

In 1848, after the Mexican War ended, McClellan served at West Point as assistant instructor of practical engineering. In 1852 he was with Captain Marcy (later his father-in-law) on an exploration of the upper Red River, between Texas and the Indian territory; and afterward he was engineer-in-charge of explorations and surveys in Texas. In 1853 he served on engineer duty in Oregon and Washington territories, and later was employed as engineer on the western division of the Northern Pacific railroad.

In March 1855, McClellan was appointed a Captain in the 1st U.S. Cavalry. That same year, he was sent to Europe as a member of a military commission to report on the condition of the European armies, and to observe the operations of both sides in the Crimean war. His colleagues were Colonel Richard Delafield of the engineers, and Major Alfred Mordecai of the ordnance corps.  The individual reports of these officers were published by Congress. McClellan's was notable for its detail and accuracy, and was republished in 1861 with the title "The Armies of Europe."

On January 18th, 1857, Captain McClellan resigned his commission to accept a position in industry as chief engineer of the Illinois Central Railroad. He became railroad's vice-president in 1858.  In 1859, he was elected president of the eastern division of the Ohio and Mississippi railroad, residing in Cincinnati, Ohio. In 1860 he was made President of the St. Louis, Missouri, and Cincinnati railroad, a position he held until the outbreak of the Civil War in 1861.

On April 23rd, 1861, McClellan was appointed Major-General of Ohio volunteers, and placed in command of the Department of the Ohio, which included the states of Ohio, Indiana, and Illinois, with portions of Virginia and Pennsylvania. Rapidly taking the field, he crossed the Ohio on May 26th into Virginia and occupied Parkersburg. This advance into West Virginia, he claimed, was made "without orders, and entirely of his own volition."  During an eight day campaign, McClellan drove the enemy from the great Kanawha, and captured 1,000 prisoners.  He wrote to Washington that "he had completely annihilated the enemy in western Virginia." 

On May 14th, McClellan was appointed a Major-General and immediately after the battle of Bull Run, McClellan was called to Washington, and on July 27th he was given command of the Department of Washington and Northeastern Virginia. While reorganizing the Army of the Potomac, he was given command on August 20th.  Upon the retirement of General Winfield Scott, on November 1st, McClellan was made commander of all the armies of the United States.

It was not until March 1862, that McClellan put the army in motion again towards Manassas.  The enemy, however, had evacuated the position the day before. Shortly thereafter, McClellan began his Peninsula Campaign, landing at Fort Monroe, which would be a base of operations, with the intention of proceeding by the James River to Richmond. Another was to proceed by York river with the co-operation of the navy. The Army of the Potomac began moving via Alexandria from March 17th to April 6th by water to Hampton Roads, and landed at Old Point Comfort. As soon as he ledt Washington his opponents declared he had left the capital undefended.  Among other intrigues, McDowell's corps of 40,000 men was diverted from marching southward to join McClellan's campaign.  McClellan was also relieved from the command-in-chief by a published order that had not been communicated to him before, and became simply commander of the Army of the Potomac.

During the Peninsula Campaign, McClellan led his forces - with characteristic caution - through the battles of Yorktown, Williamsburg, Fair Oaks, and the Seven Days.  The advance up the peninsula stagnated, and then began to reverse.  Having lost the confidence of the President and his advisers, neither McClellan's  requests for additional troops nor his advice was heeded.  On July 11th General Henry Halleck was made general-in-chief, and on August 3rd McClellan was ordered to evacuate the peninsula. He was directed also to repair in person first to Fort Monroe and then to Alexandria, and was relieved of his command and ordered to send every available soldier to the new army of Virginia under General John Pope.

The second battle of Bull Run, August 30th, 1862, was even more disastrous than the first, and on September 2nd, General Pope resigned his command. In this emergency the government looked again towards McClellan as the only man who could inspire confidence and bring order out of chaos. Flushed with recent victories, Robert E. Lee was marching into Maryland.  McClellan would need to meet and check Lee's advance with the remnants of Pope's army and the Army of the Potomac. He marched into Maryland parallel with Lee, who had advanced as far as Frederick. On the approach of McClellan, Lee fell back to Turner's and Crampton's Gaps in the South Mountain, where he was defeated and driven back. On the September 16th, Lee still had only two divisions across the Potomac, but McClellan's forces did not come into position until the 17th.  At daylight on the morning of the 17th, the engagement at Antietam began.  The battle saw horrific losses on both sides, but McClellan retained the field when Lee withdrew.

However, McClellan did not attempt any swift pursuit, save one reconnaissance in force towards Shepherdstown, which met sharp resistance.  Lee had crossed the Potomac at his leisure. McClellan then followed, advancing his army between Longstreet's corps and the main body under Lee, and halted at Warrenton to recruit.  Washington was critical of McClellan for his delay, and urgent orders were sent, imploring him to move. At last an order from the President came on November 7th, relieving McClellan of command, and conferring it upon General Burnside. McClellan was directed to await orders at Trenton, New Jersey, and afterward at New York.

Many in the army as well as in the public idolized "Little Mac", and in 1863 he visited Boston, where he was received enthusiastically.  In 1864 he was chosen to deliver the oration at West Point on the occasion of the unveiling of the monument erected to the memory of the officers and soldiers of the Regular Army. He took no further part in the war, and dedicated time towards the preparation of his "Report on the Organization and Campaigns of the Army of the Potomac," which was published by the government. He also published an edition himself, with a preliminary account of the campaign in western Virginia.

In August 1864, McClellan was nominated by the Democratic party as their candidate for the presidency of the United States. However, Lincoln's popularity had been growing as successes in the war also grew.  During the election of 1864, McClellan received just 21 electoral votes against 212, though his share of the popular vote was more impressive - he had won 1,800,000 votes against 2,200,000.

McClellan resigned his commission in the Army on September 8th, 1864, and immediately after the election he went to Europe, where he remained until 1868. On his return, he took up residence in New York City. In 1868-69, he was retained to complete the Stevens iron-clad floating battery for harbor defense. He declined the presidency of the University of California in 1868, and that of Union college in 1869.  From 1870-71, he was engineer-in-chief of the Department of Docks of the City of New York. In 1881 he was appointed by Congress as a member of the Board of Managers of the National Home for Disabled Soldiers, an office he held until his death.

During these latter years, McClellan's principal residence was in Orange, New Jersey, but in the winters he resided in New York or Washington. He was elected governor of New Jersey in 1877, served for one term with credit, and declined a renomination. He made several tours in Europe, publishing his observations in magazine articles.  He also authored several monographs illustrating his campaigns and trying to vindicate his reputation.  In 1885, McClellan died suddenly at his country residence.

An accomplished engineer and student of military history, he had no superior in his systematic knowledge of wars, battles, and tactics. He devised the McClellan saddle in 1856, which proved useful and popular. His writings include "A Manual of Bayonet Exercise," adapted from the French (1852); "Government Reports of Pacific Railroad Surveys" (1854)" "Report on the Organization and Campaigns of the Army of the Potomac" (1864)" papers in "Harper's Magazine," 1874-'7, and in "Scribner's" on Egypt and the Nile.
