The Confederate Army’s logistical challenge during the battle was primarily a Lack of supplies.

As the army moved deeper into Union territory, they encountered significant challenges in sustaining sufficient supply lines for food, ammunition, and equipment. As the campaign prolonged, these shortages became increasingly evident, impairing their operational efficiency. Confederate forces found it difficult to restock their supplies, which negatively impacted troop morale and combat preparedness. This logistical pressure, along with the casualties incurred in battle, ultimately complicated Lee's ability to implement his strategy at Gettysburg.
