Future United States President Benjamin Harrison led the 70th Indiana in a charge against Van Den Corput's Battery.

Stevenson gave the order to position Capt. Maximillian Van Den Corput's "Cherokee Battery" of four Napoleons in front of the Confederate line on the morning of May 15. This positioning, however risky, guaranteed the artillerymen would have unobstructed lines of sight. The Confederates put the guns in an earthen shelter, but two Union regiments, one of which, the 70th Indiana, was commanded by the future president of the United States, attacked before they could link these pits with their main lines. The mission was risky.

The enemy's earthworks, "whose strength, and even exact location, was only exposed by the line of fire which, with awful destructiveness, was belched into our advancing column," were attacked by Harrison and his forces as they advanced. Due to heavy Rebel fire, the Union troops, including Harrison, were forced to retreat back down the slope after infiltrating and overcoming the Rebel soldiers, leaving Van Den Corput's battery's weapons in the area between the Union and Confederate lines. Since both forces were pinned down by heavy skirmishing and artillery dueling at 3 p.m., neither side was able to retake the battery.

After dark, Union Brigadier General John Geary gave the order for soldiers to advance covertly while tearing through the earthworks and dragging all four guns back to the Union line. The successful capture of Van Den Corput's pieces made the Cherokee Battery the only artillery lost by Johnston's army during the Atlanta Campaign.
