The Signal Corps played a significant role in the Union's efforts during the Battle of Fredericksburg by facilitating communication and intelligence gathering. They used wigwag flags, torches, and other visual signals to relay messages across the battlefield. This communication was crucial for coordinating Union troop movements and relaying commands during the complex maneuvers required for operations such as river crossings and assaults against fortified Confederate positions.

At the Battle of Fredericksburg, the Signal Corps' duties included relaying information on troop movements and providing real-time updates to Union commanders, which was essential in maintaining the limited coordination that was possible given the chaotic nature of the battle.
