Stone Wall on Cemetery Ridge
The Battle of Gettysburg began in 1863. Many experts call this battle the turning point of the Civil War. Confederate General Robert E. Lee led his troops across the Mason-Dixon Line, heading for Harrisburg, Pennsylvania. However, the northern troops, led by General George Mead, met the Confederate troops at Gettysburg. The battle lasted for three days. On the last day of the battle, the rebel troops commenced Picket’s Charge. Fifteen thousand troops tried to assail the Union’s position. The northern troops held, and Lee lost the battle. Idea: Children could make a timeline of the battle.
