The stalemate on the Kennesaw Mountain front was broken when the right wing of Sherman’s forces was extended south on the old Sandtown road to this point. That development came on July 1, 1864, when Brigadier General Milo S. Hascall’s 2d division, 23d A. C. [US], moved to this strategic position, threatening Johnston’s Confederate lines of communication and retreat along the State Railroad and highways east of here and south of Kennesaw Mountain. McPherson’s Army of the Tennessee [US] joined the 23 A. C. here on July 2d and 3d. The 15th and 16th A.C. then moved east to Nickajack Creek, and the 17th moved south toward the Chattahoochee River.
