At Gettysburg, both armies faced Supply shortages, Communication issues, and Reinforcement delays challenges.

Supply shortages were a major concern, as both Union and Confederate forces faced challenges in providing sufficient provisions for their troops, raising worries about food and ammunition availability. Communication problems emerged, making it difficult to relay orders and coordinate movements, which hindered effective strategic planning. Furthermore, delays in reinforcements were substantial, as the prompt arrival of troops could significantly change the dynamics of the battle. These logistical challenges complicated operations for both sides and impacted the overall outcome of the conflict.
