James Longstreet (January 8, 1821 – January 2, 1904) was one of the foremost Confederate generals of the American Civil War and the principal subordinate to General Robert E. Lee, who called Longstreet his "Old War Horse." Longstreet served under Lee as a corps commander for many of the famous battles fought by the Army of Northern Virginia in the Eastern Theater, but also with General Braxton Bragg in the Army of Tennessee in the Western Theater. Biographer and historian Jeffry D. Wert wrote that "Longstreet ... was the finest corps commander in the Army of Northern Virginia; in fact, he was arguably the best corps commander in the conflict on either side."
Perhaps no Confederate officer is surrounded by more controversy than James Longstreet. Called “Old Pete” and “My Old War Horse” by General Robert E. Lee, Longstreet was Lee’s trusted advisor and friend. Nonetheless, after the war, Longstreet became the target of many “Lost Cause” attacks. Longstreet's letters to the New Orleans Times, his support of the Republican Party, and his memoirs alienated many Southerners.
Fall 1830 - 1838 -- James Longstreet lived with his uncle, Augustus Baldwin Longstreet, and aunt Francis Eliza Parke Longstreet, and their two daughters on their plantation, Westover, on the outskirts of Augusta, Richmond County, Georgia. James attended Richmond County Academy. . As a fervent proponent of states’ rights untempered by the countervailing view of the indissolubility of the Union, Longstreet's Uncle Gus had a strong influence on James. 
Longstreet opposed CSA General Robert E. Lee's plan to attack at Gettysburg, though he followed Lee's orders. Longstreet was also reluctant to follow Lee's orders for a direct assault on the third day of fighting, but still obeyed the command. That charge resulted in heavy casualties, and a Union victory at Gettysburg.
After the Civil War
With the war over, Longstreet moved to New Orleans, where he upset some by joining the Republican Party and by accepting the process of Reconstruction. President Ulysses S. Grant conferred political appointments on his old friend and fellow West Point graduate James Longstreet.
In 1872 Longstreet's reputation was further tarnished when some Confederate officers — led by Jubal A. Early — claimed that Longstreet had disobeyed Lee's orders at Gettysburg, and held him responsible for the South's defeat. Though Lee's records from the war did not mention any such disobedience, Longstreet's criticism of Lee while defending himself did not help his cause.
In 1875, Longstreet relocated to Gainesville, Hall County, Georgia.
In 1880 former Union general and Republican President Rutherford B. Hayes named him the U.S. ambassador to Turkey, a position Longstreet held for one year.
In 1896 Longstreet finished his memoir and also continued to defend his actions during the Civil War.

Calhoun in persuading U.S. Representative from the 1st District of Alabama, Reuben Chapman, to nominate James to attend West Point beginning in July 1838.
