James Longstreet was one of the most prominent ‘Confederate’ generals of the American Civil War (1861–1865). He served as the principal subordinate to General Robert E. Lee, who named him his “Old War Horse.” He served as a corps commander under Lee, in many major battles fought by the ‘Army of Northern Virginia’ in the Eastern Theater. He also worked with Braxton Bragg as part of the ‘Army of Tennessee’ in the Western Theater. A graduate of the ‘United States Military Academy’ at ‘West Point,’ he fought many notable battles of the Mexican–American War. He was badly wounded in the Battle of Chapultepec. In spite of losing three of his children to scarlet fever, he fought the Seven Days' Battles of 1862 valiantly. His other notable contributions were at the Battle of Second Bull Run and the Battle of Fredericksburg. He was dragged into a controversy when, at the Battle of Gettysburg in 1863, he markedly disagreed with General Lee on the war tactics to be used and then reluctantly took charge of several unsuccessful attacks on the Union forces, such as the Pickett's Charge. He was also involved in the Battle of Chickamauga, The Battle of the Wilderness, and the Siege at Petersburg. Following the war, Longstreet joined the ‘Republican Party.’ He supported the 1868 presidential campaign of Ulysses S. Grant. This earned him a lot of criticism and the nickname “scalawag.” He served as the U.S. ambassador to Turkey and was also a railroad commissioner before he died in 1904.
