It was drawn from the peacetime 4th Army District. When mobilised, it consisted of three divisions, a brigade-strength detachment, one horse cavalry regiment and one independent infantry regiment. It formed part of the 1st Army Group, and was responsible for defending a large section of the Yugoslav–Hungarian border, being deployed behind the Drava river between Varaždin and Slatina. Like all Yugoslav formations at the time, the 4th Army had serious deficiencies in both mobility and firepower.

The **4th Missouri Infantry Regiment** was formed on April 28, 1862, and served in the Confederate States Army during the American Civil War. The infantry regiment did not see action at the Battle of Farmington on May 9, and the Battle of Iuka on September 19 despite being part of the Confederate force present at those battles. As part of Brigadier General Martin E. Green's brigade, the regiment participated in three charges against Union lines on October 3, 1862, during the Second Battle of Corinth. The following day, the regiment, along with the rest of Green's brigade, attacked the new Union lines. Despite initial success, the attack was repulsed by a Union counterattack. The regiment ceased to exist as a separate unit when it was combined with the 1st Missouri Infantry Regiment on November 7, 1862, to form the 1st and 4th Missouri Infantry Regiment (Consolidated).

Hartranft. Logistical difficulties bedeviled the regiment, which served as part of the garrison of Washington, D.C., until late June, when it was sent into Northern Virginia to join in the army of Brigadier General Irvin McDowell.

The **6th Regiment Massachusetts Volunteer Militia** was a peacetime infantry regiment that was activated for federal service in the Union army for three separate terms during the American Civil War (1861-1865). The regiment gained notoriety as the first unit in the Union Army to suffer fatal casualties in action during the Civil War in the Baltimore Riot and the first militia unit to arrive in Washington D.C., in response to President Abraham Lincoln's initial call for 75,000 troops. Private Luther C. Ladd of the 6th Massachusetts is often referred to as the first Union soldier killed in action during the war.

The **8th Missouri Infantry Regiment** was an infantry regiment of the Confederate States Army during the American Civil War. From May 1861, the war began affecting events in the state of Missouri. In 1862, Confederate recruiting activities took place in Missouri, despite that the state never formally joined the Confederacy, and a cavalry regiment was formed in Oregon County, the nucleus being former members of the Missouri State Guard. On September 2, the unit entered Confederate service, but it was reclassified as infantry ten days later. After many of the men transferred to other units, the regiment was reclassified as a battalion on October 19 and named the **7th Missouri Infantry Battalion**, also known as **Mitchell's Missouri Infantry**. It participated in a Confederate offensive at the Battle of Prairie Grove on December 7. During the battle, the unit made several charges against the Union lines but was repeatedly repulsed by artillery fire. The regiment spent most of early 1863 encamped near Little Rock and Pine Bluff in Arkansas.
