General Ulysses S. Grant
He was born on April 27, 1822 in Point Pleasant Ohio. He went to United States Military Academy at West Point, and public schools in Georgetown, Ohio. He was once the President on the United States and the youngest of them at the age of 46. Grant was important to the Civil War because he won most of the Union's battles and without him, the North would have lost the Civil War. He died on July 23, 1885 just as his memoirs were finished and was buried in New York City. The world will never forget him as General Grant.
George McClellan
George Brinton McClellan was born on December 3, 1826 in Philadelphia, Pennsylvania. His education was at U.S Military Academy. He first worked at a railroad industry until the Civil War began. He also served in the Mexican War before he served in the Civil War. McClellan was placed in command of the Union's Department of the Ohio when he was there, yet Lincoln was discouraged by McClellan's inability to claim Richmond. After that, he was removed from being general of the Union.
Robert E. Lee
Lee was born on January 19, 1807 in Stratford Hall, Virginia. He went to West Point Military Academy (The same as Grant). He was always a very good student in school and was never bad. He is best known for leading the Confederates during the Civil War. Lee is considered a heroic figure in the south; in fact, there is a museum dedicated in his honor in Stratford Hall! His family tree has a lot of important people in it like a president, a Chief Justice of the U.S and one of the signers of the Declaration of Independence. Lee's father "Light- Horse Harry" served in the Revolutionary War as a Calvary leader. After graduating from West Point, he married Mary Custis who was the great granddaughter of George and Martha Washington. He was instructed to end slavery and it took him about an hour to end it. Unfortunately he was turned down by Lincoln to lead the Union and he resigned from the military. On April 18, 1861 he agree to lead Confederate Forces. On May 18, 1862 he took control of the Army of Northern Virginia. Bad things occurred when he tried to cross the Potomac; he barely escaped the Battle of Antietam. On July 1, 1863 Lee's forces suffered negative effects in the Battle of Gettysburg and that almost defeated his army. By December of 1864, General Grant had the upper hand disseminating much of Richmond, the Confederate Capitol and Petersburg. In early 1865 the future of the Civil War was clear. On April 2, Lee abandoned Richmond, and a week later he surrendered to General Grant at a private home in Appomattox, Virginia. In April 1865, General Lee returned to his family. After the war he was accepted to be president at a small college in Western Virginia. Lee suffered a massive stroke and died on October 12, 1870.
T.J "Stonewall" Jackson
T.J "Stonewall" Jackson was born on January 21, 1824 in Clarksburg, Virginia. He graduated from West Point in 1846 and began his military career with the U.S Army as a Brevent Second Lieutenant in the Mexican- American War in 1846 through 1848. That is where Jackson met General Robert E. Lee. After all of his hard work being there and going a good job, he was promoted to rank of major. In 1851, he resigned from the military and accepted a teaching position at Virginia Military Institute in Lexington. He then commanded at Harper's Ferry and lead troops into the epic battle of First Manasses. That's how he got his nickname "Stonewall". Jackson conducted very efficient military maneuvers, and that lead to 7 days' battle. Sadly on May2, 1863, Jackson was wounded by fire while making reconnaissance with a member of staff and died 8 days later of pneumonia. He was buried in Lexington, Virginia.
