Chickamauga Battlefield

This is the site from Chickamauga Battlefield where Confederate Lt. General Longstreet's troops attacked from the woods across Lafayette Road, past the Brotherton Cabin, and across the field and into the newly created gap. The gap was created as a result of the Union Brigadier General Rosecrans receiving an erroneous report that Union Brigadier General Brannan's division had moved out of position, thus creating, it was believed, a gap in the federal Line. When Union Brigadier Wood division was ordered to fill that supposed gap, he created a real one. Doesn't appear that the left hand was talking to the right one.
As one can see from the picture the Battle of Chickamauga, September 19-20, 1863 dates, was fought mostly in a wooded area. The battles was the most significant Union defeat in the Western Theater and involved the second highest number of casualties in the war following the Battle of Gettysburg.
