Confederate General Joseph E Johnston’s Army of Tennessee moved into a line between Big Kennesaw Mountain and Little Kennesaw Mountain. Union Major General William Tecumseh Sherman started probing this line on June 19th 1864, looking for a week spot. Sherman decided the spot was the left flank, and he sent Hooker’s XX Corps with the support of Major General John McAllister Schofield to take on that flank near Powder Springs. Johnston predicted the Union movement and sent Confederate Lieutenant General John Bell Hood’s Corps to cover the Union movement.
Confederate Major General Cater L Stevenson one of Hood’s division commanders moved on the afternoon of June 22nd 1864 toward Kolb’s Farm on the south Powder Springs Road. They ran into heavy skirmishing with the Union 14th Kentucky and 123rd New York. Hood ordered his whole Corps; about 11,000 men, to advance up the Powder Springs Road pushing the Union troops ahead of them. Hooker had information about Hood’s coming troops and had entrenched his Corps of about 15,000 men across the Powder Springs Road. The marshy terrain and well placed Union artillery stalled Hood’s attack and caused him to have to withdraw.
It was a one sided battle with the Union side coming out on top. Confederate losses were about 1,000, the Union only had about 350 casualties.
