During the Battle of Gettysburg, Mary Todd Lincoln is shown in the White House War Room with the president and his military advisors looking at a huge wall map of the Union position on the second day of the battle as the fighting raged miles away. She comments on the importance of Little Round Top to the Union army. In actuality, minute details of the battle were not made known to Lincoln and his advisors until after the fighting ended as there was no quick communication between the Union army and Washington during the actual fighting, since the nearest telegraph office was in Gettysburg, which was occupied by the Confederates. The notion that Lincoln and his advisors had a real time detailed map of the Union position during the battle listing the names of geographic features like Cemetery Ridge and Little Round Top as these positions were coming under attack is ludicrous.
