DAY ONE

The Battle of Gettysburg begins: On the morning of July 1, 1863, Confederate cavalry ran into Union horsemen on the Cashtown Road, northwest of town. Each side sent for help. The rebels got there first, and by afternoon had driven the Federals south of town, where they rallied into defensive positions on Culp's Hill and Cemetery Hill.

DAY TWO

The Battle of Gettysburg, the second day: By the morning of July 2, 1863, 150,000 Union and Confederate troops had converged on the little Pennsylvania town. The southerners occupied a line west of the Emmittsburg Road, along the Seminary Ridge. The northern men waited along Cemetery Ridge - a slightly more elevated crest that ran south toward two hills, Big and Little Round Top. Lee's plan called for an assault on the left, or southernmost, end of the Union line.

DAY THREE

Pickett's Charge: At about three in the afternoon of July 3, 1863, Robert E. Lee ordered the most fateful assault of the war, against the center of the Union line.
