Confederate General, Robert E. Lee, leads the Army of Northern Virginia, on a massive raid into Union territory. Lee’s invasion is designed to secure Desperately Needed Supplies, undermine civilian morale, and bolster anti-war elements in the North. On July 1, 1863, the Army of the Potomac, under Union General George Meade, stumbles across the Rebels at Gettysburg, Pennsylvania. Union General John Buford and his cavalry, reinforced by two divisions of infantry, defend the low ridges on the northwest of town. Around 7:30am, Union soldier Marcellus Jones, of the 8th Illinois Cavalry, fires the First shot of the battle. The Union lines collapse under Confederate assaults, forcing a retreat to the high ground at Cemetery Hill. Union Major General Winfield Hancock remarks, “I think this is the strongest position by nature, upon which to fight a battle, that I ever saw.”
