The Atlanta Campaign, May-September, 1864 - Over the next several months the Missouri Brigade and French's Division see some of the harshest campaigning they would experience throughout the war. They aren't engaged in every major battle but they are under fire, marching or digging earthworks almost every day of the campaign. From the New Hope Church line, the Lattimer House, Kennesaw Mountain, Chattahoochee River line, Peachtree Creek, and in the Atlanta defenses, the Missourians see constant skirmishing and artillery fire. Like their experience at Vicksburg, the lines are often just yards apart and sharpshooting goes on day and night. One of the major battles they play a notable part in is Kennesaw Mountain, defending Pigeon Hill against Federal attacks on June 27. The Missouri Brigade numbered 1,630 men on May 6 and about 1,100 by September, losing 531 men throughout the campaign.
