From 1845 to 1846, Pemberton and the 4th Artillery were part of the U.S. military occupation of Texas before the admission of the Republic of Texas into the United States as the 28th state in 1845. Then the 4th was sent to Mexico at the start of the Mexican–American War the following year. He fought at the Battle of Palo Alto on May 8, 1846, and at the Battle of Resaca de la Palma the next day. He then fought well at the Battle of Monterrey in that fall and was appointed a brevetcaptain "for Gallant Conduct in the several Conflicts at [Monterrey]" on September 23.[4]
Pemberton then fought in the U.S. Army's 1847 actions in Mexico, including the Siege of Vera Cruz in March, the Battle of Cerro Gordo in April, the skirmish near Amazoque in May, the capture of San Antonio and the Battle of Churubusco in August, and most notably in the Battle of Molino del Rey that September. Pemberton was appointed a brevet major[5] for his performance at Molino del Rey on September 8. He then was part of the storming of Chapultepec Castle on September 13, and the Battle for Mexico City that day and the next,[4] where Pemberton was wounded.[3] Pemberton held the position of Aide-de-Camp to Brevet Brigadier GeneralWilliam J. Worth from August 4, 1846, to May 1, 1849, and was a fellow staff lieutenant in the same division as his future opponent in the Civil War, Ulysses S. Grant.[4] He was an original member of the Aztec Club of 1847 – a military society founded by U.S. Army officers who served in Mexico City during the military occupation following the war.
After the war with Mexico, Pemberton and the 4th Artillery served in garrison duty at Fort Pickens near Pensacola, Florida, in 1849. He then fought in Florida during hostilities against the Seminoles in 1849 and 1850. The 4th returned to garrison duty at New Orleans Barracks in New Orleans, Louisiana, in 1850, and Pemberton was promoted to captain on September 16. He next served in Fort Washington, Maryland, along the lower Potomac River below the capital in 1851 and 1852, at Fort Hamilton, New York, from 1852 to 1856. He and the 4th Artillery fought again in Florida during further hostilities against the Seminoles from 1856 to 1857.[4]
Pemberton and the 4th were then on frontier duty at Fort Leavenworth, Kansas, from 1857 to 1858, and participated in the Utah War in 1858. He was then stationed at Fort Kearny in the New Mexico Territory in 1859, at Fort Ridgely in Minnesota from 1859 to 1861. After returning from the West in April 1861, he passed through Baltimore during the infamous Baltimore riot of 1861 in command of a regiment in transit on April 18–19, 1861, en route to Fort McHenry. Later he was briefly on garrison duty at the Washington Arsenal in Washington, D.C., in April 1861.[4]
American Civil War
At the start of the American Civil War in 1861, Pemberton resigned from his commission in the United States Army and joined the Confederate States Army, despite his birth in a free state and the fact that his two younger brothers both fought for the United States. He resigned his commission, effective April 29, despite pleas from his family and his former commander Winfield Scott.[3] His decision was due to the influence of his Virginia-born wife and many years of service in the slave states before the war.[7] He was appointed a lieutenant colonel in the Army of the Confederate States of America (ACSA) on March 28, and was made assistant adjutant general of the forces around and in the Confederate capital of Richmond, Virginia, on April 29, the date of his resignation from the U.S. Army. He was promoted to colonel on May 8. On May 9, Pemberton took a commission as a lieutenant colonel in the Artillery of the Provisional Army of Virginia.[8] Upon the absorption of the Provisional Army of Virginia into the PACS, Pemberton was appointed a major of artillery, a line field commission, on June 15, 1861, and was quickly promoted to brigadier general two days later. His first brigade command was in the Department of Norfolk, Virginia, leading its 1st Brigade from June to November.[3]
Pemberton was promoted to major general on January 14, 1862, and given command of the Confederate Department of South Carolina and Georgia, an assignment lasting from March 14 to August 29,[3] with his headquarters in Charleston, South Carolina. As a result of Pemberton's abrasive personality, his public statement that if he had to make a choice, he would abandon the area rather than risk the loss of his outnumbered army,[9] and the distrust of his free-state birth, the governors of both states in his department petitioned President of the Confederate States of AmericaJefferson Davis for his removal. Davis needed a commander for a new department in Mississippi and also a command for Gen.P.G.T. Beauregard, so he sent Pemberton west and assigned the more popular Beauregard to Charleston.[10]
Vicksburg
On October 10, 1862, Pemberton was promoted to the rank of lieutenant general,[3] and assigned to defend the fortress city of Vicksburg, Mississippi, and the Mississippi River, known as the Department of Mississippi and East Louisiana. Davis gave him the following instructions regarding his new assignment: "... consider the successful defense of those States as the first and chief object of your command." Pemberton arrived at his new headquarters in Jackson, Mississippi, on October 14.[11]
In an attempt to carry out his orders from both Davis and Gen. Joseph E. Johnston, Pemberton and his Army of Mississippi set out east to combine with Johnston's forces gathering around Jackson while remaining in contact and covering Vicksburg. Another order from Johnston changing their proposed meeting location caused Pemberton to turn around. When he did, he accidentally collided with Grant's army at the Battle of Champion Hill on May 16 and suffered a significant defeat. Pemberton retreated to the Big Black River, where he fought and suffered even more heavy losses on May 17.[12] Pemberton resolved to defend Vicksburg and led his defeated men back into its defenses on May 18. In the process, he gave up the high ground on Hayne's Bluff, which Sherman had failed to take in December. Johnston had advised him that if this ground ever fell, Vicksburg would be untenable and that he should escape with his army of 31,000, sacrificing the city. Pemberton refused to take this advice.[13] He held firm for over six weeks while soldiers and civilians were starved into submission. (Pemberton, well aware of his reputation as a Northerner by birth, was probably influenced by his fear of public condemnation as a traitor if he abandoned Vicksburg.)
On the evening of July 2, 1863, Pemberton asked in writing his four division commanders if they believed their men could "make the marches and undergo the fatigues necessary to accomplish a successful evacuation" after 45 days of siege. With four votes of no, the next day, Pemberton asked the U.S. soldiers for an armistice to allow time for the discussion of terms of surrender, and at 10:00 a.m. on July 4, he surrendered the city and his army to Grant. The written terms (which in the first talks were simply unconditional surrender) were negotiated so that the Confederate soldiers would be paroled and:[14]
...be allowed to march out of our lines, the officers taking with them their side-arms and clothing, and the field, staff, and cavalry officers one horse each. The rank and file will be allowed all their clothing, but no other property.[14]
Pemberton surrendered 2,166 officers and 27,230 men, 172 cannons, and almost 60,000 muskets and rifles to Grant.[14] This, combined with the successful Siege of Port Hudson on July 9, reestablished the United States complete control over the Mississippi River, a major strategic loss for the Confederacy that cut off Lt. Gen. Edmund Kirby Smith's command and the Trans-Mississippi Theater from the Confederacy for the rest of the war.
After his surrender, Pemberton was exchanged as a prisoner on October 13, 1863, and returned to Richmond. There he spent some eight months without an assignment. At first, Gen. Braxton Bragg thought he could use Pemberton. Still, after conferring with his ranking officers, he advised Davis that taking on the discredited lieutenant general "would not be advisable." Pemberton finally wrote Davis directly, asking to return to duty "in any capacity in which you think I may be useful." Davis replied that his confidence in him remained unshaken, saying:[15]
I thought and still think that you did right to risk an army for the purpose of keeping command of even a section of the Mississippi River. Had you succeeded none would have blamed; had you not made the attempt, few if any would have defended your course.[15]
Pemberton resigned as a general officer on May 9, 1864, and Davis offered him a commission as a lieutenant colonel of artillery three days later,[3] which he accepted, a testimonial of his loyalty to the Confederacy and the Confederate cause.[16] He commanded the artillery of the defenses of Richmond until January 9, 1865. He was appointed inspector general of the artillery as of January 7,[3] and held this position until he was captured in Salisbury, North Carolina, on April 12. Along with Pemberton and his 14 remaining guns, the U.S. soldiers rounded up about 1,300 men and nearly 10,000 small arms.[17] There is no record of his parole after his capture.[3]
Postbellum life
After the war, Pemberton lived on his farm near Warrenton, Virginia, from 1866 to 1876. He carried on a feud with Johnston about the Vicksburg campaign.[2] His mother, Rebecca Clifford Pemberton (1782–1869), survived her husband John Pemberton (1783–1847) by more than two decades, and a few years after her death, Pemberton returned to Pennsylvania.
Death and legacy
Pemberton died in Lower Gwynedd Township, Montgomery County, Pennsylvania, on July 13, 1881, although his widow Martha Thompson Pemberton would survive until 1907. The families of several famous people, including General George Meade and Admiral John A. Dahlgren (whose brother also served as a Confederate General), protested against the unrepentant Confederate Pemberton's burial at Laurel Hill Cemetery in Philadelphia, where his mother and father had been buried. He was interred at the cemetery despite a supposed decision that he would be interred elsewhere.[18] He is the only Confederate general buried in Philadelphia.[19]
A statue depicting Pemberton, sculpted by Edmond Thomas Quinn, was erected in the Vicksburg National Military Park. His grandson, also John C. Pemberton,[20] in 1942 published a book about his grandfather's defense of Vicksburg, and donated family papers and his research concerning his grandfather to the University of North Carolina, which maintains them in its Special Collections.[21]
