Pickett's Charge was an infantry assault ordered by Confederate Gen. Robert E. Lee against Maj. Gen. George G. Meade's Union positions on Cemetery Ridge on July 3, 1863, the last day of the Battle of Gettysburg in the state of Pennsylvania during the American Civil War.
When Lee learned that Meade was in Pennsylvania, Lee concentrated his army around Gettysburg. Elements of the two armies collided west and north of the town on July 1, 1863. Union cavalry under Brig. Gen. John Buford slowed the Confederate advance until Union infantry, the Union 1st and 11th Corps, arrived.
