The battle strategy primarily used by the Confederacy during the Battle of Gettysburg was Aggressive frontal assaults.

General Robert E. Lee aimed to take the initiative and overwhelm Union positions through direct attacks. This approach culminated in the infamous Pickett's Charge on July 3, 1863, where Confederate forces launched a massive assault against the Union center. Despite their courage, these frontal assaults resulted in devastating casualties for the Confederates and ultimately failed to break Union lines. This strategy reflected Lee's belief in the effectiveness of offensive operations despite the inherent risks involved.
