Final answer:

Step-by-step explanation:
The statement about the Battle of Gettysburg that is accurate is that it was the last time the Confederacy would invade the North. This decisive battle, which was fought over three days from July 1 to July 3, 1863, ended with a significant defeat for General Robert E. Lee and his Confederate forces. After fierce fighting and heavy losses on both sides, Lee's army had to retreat back to Virginia, marking a turning point in the Civil War in favor of the Union. The engagement at Gettysburg had the highest casualty rate of the Civil War and the famous Pickett's Charge resulted in over half of the Confederate soldiers being killed or wounded.
The North, led by General George Meade, did not pursue Lee's forces immediately after their withdrawal. The battle was a crucial victory for the Union and coincided with another Union triumph at Vicksburg, which demonstrated a shift in the war's momentum. As such, Gettysburg marked a pivotal moment where the Confederacy's capacity to mount significant offensives into Union territory was effectively ended.
