[Author's note: Okay, so Lieutenant Cogley wasn't present for duty when his company fought against the Confederates during Price's 1864 invasion of Missouri. But after the war, Cogley wrote a history of the 7th Indiana Cavalry.]
Thomas S. Cogley was born in Liberty, Union County, Indiana, on November 24, 1840. Cogley was living in LaPorte, Indiana, when he volunteered for Federal service in 1861. Cogley mustered into Company C, 8th Indiana Infantry, for a 90-day enlistment and served until mustered out on the expiration of his term of enlistment. He fought in the battle of Rich Mountain in West Virginia.
Next Cogley mustered into Company C, 29th Indiana Infantry as a sergeant. Cogley was wounded in the knee at the Battle of Shiloh. After recuperating he returned to his regiment but was discharged in January 1863 because of poor health.
Cogley returned to LaPorte and took up the sudy of law. Then in August, Cogley enlisted as an orderly sergeant in Company F, 7th Indiana Cavalry. Cogley was with the regiment duringthe expedition to West Point, and in the saber charge on the evening of February 22, 1864; on the expedition to Guntown and in the Battle of Brice's Crossroads, June 10, 1864; on the expedition to Port Gibson and Grand Gulf, Mississippi, in July 1864.
During the Expedition to Oxford, Cogley was "shot in [his] right side with a revolver, the ball striking the lower right rib, and following around in front and lodging over the pit of the stomach, but [he] was still able to keep the saddle" during the fighting near Lamar, Mississippi. Cogley became separated from his company and was captured. Cogley was able to escape on October 10, 1864, but did not rejoin the regiment until after its service against Maj. Gen. Sterling Price in Missouri.
After the war, Cogley returned to LaPorte, Indiana, and finshed his study of law, after which he began to practice law in LaPorte County.
