Everett Marshall

Everett Marshall was an American Civil War soldier on the side of the Confederate States of America. He was present during the Battle of Gettysburg but, due to a malfunction caused by the Sixth Doctor's TARDIS, was flung forwards to the 1980s. There he became a state ward patient due to no one believing his story, under the watch of Doctor Carl Jenner. In 1986, another rift in the Time Vortex sucked Marshall and Dr. Jenner back to the year 1862, at which point Marshall attempted to use his knowledge of history to change the events of the war so that the Confederates would beat the Union Army.

Biography
Marshall was a member of the 2nd Georgia Infantry Regiment at Gettysburg in 1863. He served with his brother, Frankie Marshall, and several of his close friends. However, during the actual battle, Everett was suddenly shifted through cracks between the Vortex Barriers, sending him forwards in time to the 1980s.

Unbeknownst to Marshall, this was actually caused by a malfunction in the Sixth Doctor's TARDIS, which later arrived at Gettysburg among a specific series of possible events. (NOTVALID: Doctor Who and the Rebel's Gamble: "Player's Note", et. al)

In the 1980s, Marshall eventually was committed as a state ward patient. In 1986, he was given a new Psychiatrist named Doctor Carl Jenner. Jenner was himself a Civil War enthusiast and recreationist, and believed he could help Marshall. Marshall began to speak to Jenner of his survivor's guilt, and his believe that the other members of the 2nd Georgia Infantry were trying to pull him back. He reflected on his guilt of his brother Frankie, who records claimed died in the battle which he was taken from. Marshall continued to insist that he felt like something was pulling him back, just as another crack between the Vortex Barriers opened, sending both him and Jenner back to the year 1862.
