Dr. Adam McGill Lyle and his wife, Harriett Feaster, who lived three miles south of Russellville, had seven sons in the Confederate Army. Thomas was one of eleven Logan County men to be killed at Shiloh. Harriett went to the battlefield and saw him buried. She rode in a buggy over the war area and carried to the soldiers food and money she had sewn in her skirts. She made a trip to Washington to ask President Lincoln to intercede for her son John, sentenced by the Federals to be hanged as a spy. He was exchanged as a prisoner of war.

Bri. Gen. Stephen Burbridge of the Union Army, who commanded all Federal troops in Kentucky from February 1864 until 1865, came to be known as "the most hated man in Kentucky" was from the Red Oak community in Logan County. He wrote Order No. 59 which provided for the shooting of four southern guerrilla prisoners in retaliation for any one Northern supporter killed by guerrillas. One such shooting took place on the public square in Russellville and merchants were forced to close up shop and witness the shooting.

Skirmish at Whippoorwill Bridge took place on Dec. 9, 1861 and was the first conflict of the War in Logan County. Five miles west of Russellville where present day 68/80 crosses Whippoorwill Creek was the site of the small battle. Fifty Confederate soldiers of the 9th Kentucky Infantry (later know as the Orphan Brigade) and ninety Union Soldiers engaged in the action which resulted in the first casualities of the war for that unit.

The Keysburg community in the southern part of the county was the point at which many Logan Countians crossed the state line to join the Confederacy. Even though they enlisted at Clarksville, Tennessee, they were members of the Kentucky Brigade. Logan County was occupied by Confederate troops from the beginning of the war until February 1862 when the Union forces took control until the end of the war.
