18th Illinois Infantry

The 18th Illinois Infantry regiment¹ was organized at Aurora, Illinois, with US Colonel Michael K. Lawler being appointed its commander.  It was mustered into Federal service on May 28, 1861.  It would be sent to Bird’s Point, Missouri, in June and on to Cairo, Illinois on October 5.  It would remain in the District of Cairo until February 1862, when it was assigned to the First Brigade (Colonel Richard J. Ogelsby) of US Brigadier General John A. McClernand’s First Division of the District of Cairo.

In February 1862, the 18th Illinois would participate in the capture of Forts Henry and Donelson.  As part of McClernand’s Division, they would be repulsed during CS Brigadier General Gideon J. Pillow’s break out attempt, at Fort Donelson.  With US Brigadier General Ulysses S. Grant arriving at the battle, they would be reformed and participate in the counter attack that would lead to the capitulation of the fort.  Colonel Lawler would be wounded during Donelson with command passing to Major Samuel Eaton.

The regiment would move to Pittsburg Landing, Tennessee in March and would be in bivouac there on March 23.  On April 6th, Confederate forces under the command of CS General Albert Sidney Johnston, would attack Grant’s Army of the Tennessee, at Pittsburg Landing.  The ensuing Battle of Shiloh would be a Union victory, but it would come at a terrible cost.  Still part of McClernand’s First Division, the 18th Illinois would be engaged in some of the fiercest fighting at the Crossroads, and the Hornet’s Nest.

From April 29 to May 30, the regiment would participate in the advance, and siege of Corinth, Mississippi.  In early July, the regiment would have a new commander, Major Daniel H. Brush, from Carbondale, Illinois.  They would be detached to Bethel, and then to Jackson, arriving on June 15, 1862.  They would remain there May 30, 1863, participating in battles against CS Major General Nathan Bedford Forrest, in west Tennessee.  Companies A and E would fight against Forrest at Parker’s Crossroads on December 30 and 31, 1862.  They would participate in the pursuit of Forrest’s cavalry to Clifton, Tennessee.

In July 1863, they would participate in Steele’s expedition against Little Rock, Arkansas.  On September 10, 1863 the 18th would fight at Bayou Forche, leading to the capture of Little Rock.  For the remainder of the war the 18th Illinois would be on duty at Little Rock, Pine Bluff and Duvall’s Bluff, all in Arkansas.  Non–Veterans would muster out on May 28, 1864, with the regiment mustering out of Federal service on December 16, 1865.  They would be discharged at Camp Butler, Illinois on December 31, 1865.

The regiment would suffer a total of 394 casualties during the Civil War.

About Michael Noirot

I grew up in the Central Illinois farming community, of Dunlap. Growing up, I played sports, tinkered with cars and enjoyed photography. While I did well in school, I did not become passionate about history until my early 30's. I have built a large library, of books on early America, politics and the Civil War. I am an avid reader. Fortunately, I have had plenty of opportunities to travel, over the years, and have been to most of the Civil War battlefields. I work while I travel, so more often than not, I am up, in the middle of the night, to get sunrise pictures, or I will be out until well after dark, exploring Civil War battlefields. I have other hobbies, and passions, that I really enjoy. Number one on the list would be guitar. I play my guitars on a regular basis, and enjoy the Bluegrass, and Contemporary Christian (CCM) genres. I play a style of guitar, called FLATPICKING, where using a flat pick, you play lead solos, similar to the way a fiddle would have been played during the 19th and early 20th Centuries. Laura, my wife, and I also enjoy scuba diving, travel and spending time at our property, in the country. Lastly, we spend as much time with our families, as possible. Thanks for stopping by.

    I found your site while searching for 18th Illinois Infantry. I live in Anderson, Indiana and thought you would be interested in knowing that W.D. Hearl is buried in Maplewood Cemetery. He served in the 18th Illinois Infantry; Co G. He is on Findagrave, memorial 64827489. Perhaps you know of a database for the 18th and could be sure the Mr. Hearl is added. I read on your bio about your love history so I figured you would know what to do.
    Thanks for all of the work you have done on the Civil War.
