The correct answer is B) they needed more weapons to continue aggressive movements.
<em>Southern disadvantages led to the Battle of Gettysburg in that they needed more weapons to continue aggressive movements. </em>
One of the disadvantages of the Confederated Army was the lack of supplies. They needed more supplies to keep on with their aggressive movements after the Potomac victory. The Southern Army had fewer weapons and supplies compared to the Union's Army. They also did not have the same amount of money that the Union had to support the war effort.
Anyway, the Battle of Gettysburg was fought from July 1 to 3, 1863, and is considered the bloodiest battle of the war and a turning point for the Union Army.
