10th Missouri Infantry Regiment (Confederate)

The 10th Regiment Missouri Infantry was an infantry regiment that served in the Confederate States Army during the American Civil War. It was also known as the 12th Regiment or Steen's Regiment, the latter referring to the first regimental commander Alexander E. Steen.

History
The regiment was mustered east of Fort Smith, Arkansas in Camp Mulberry on November 10, 1862. The regiment was made up by approximately 650 soldiers with a variety of equipment. These soldiers mainly came from previously established units that had been disbanded. These units include a battalion of William O. Coleman's former cavalry regiment led by Alexander E. Steen. Other company sized elements included those from John M. Johnson's mounted and two more former Missouri State Guard that had been led by John W. Priest and John H. Winston.

Within a month of the formation of the regiment, they marched north in December to meet union forces at the Battle of Prairie Grove. On December 7, 1862, as part of Parson's brigade, the 10th was aligned to defend the main confederate body of forces. By mid-day, Parson's brigade was moved up to the main line driving union forces back. This gain was stalled by union artillery. The attack cost the regiment dearly; casualties totaled 31 dead, 62 wounded and 3 missing, including the deaths of both the commander, Colonel Alexander E. Steen, and executive officer, Lieutenant Colonel Chappell. Confederate forces were withdrawn by the field commander, Major General Thomas C. Hindman. After the death of the regimental commander, Alexander Corbin Pickett was promoted to the command. The regiment retreated to Van Buren, Arkansas and in the beginning of the new year moved on to Little Rock until May.

In late May, Major General Sterling Price ordered the 10th to join his forces, marching them northeast of Little Rock in Jacksonport. Now with Price's division, in late June they moved southeast to the Mississippi River to confront the a union garrison at Helena, Arkansas. This march took 12 hard days, marching across flooded river bottoms. In the pre-dawn hours of July 4, 1863, simontanious attacks against Batteries A, C and D were planned. The 10th, in formation with the Missouri Brigade, set prepared to attack union troops on Graveyard Hill or Battery C at 4:00 am, quickly running the union troops out of their fortifications. The rest of Price's division was not quite as successful, meeting with strong resistance and leaving the 10th without proper support. Left without a choice, Pickett called for a retreat of his division, with disastrous results; the division was left nearly decimated with 11 killed, 41 wounded and 237 captured with only 236 able bodied soldiers remaining. By August, the 10th returned to defend Little Rock against union assault, however, the attack came to a different point in the city, leaving the regiment spared from harm. With the city falling into Union influence, the regiment was forced south to Arkadelphia on September 10th.

After the devastating blow suffered by the regiment, additional troops and unit realignment would be necessary. The 12th Missouri Infantry Regiment, also devastated by the effects of war, restructured with their 200 remaining men into two companies, replacing Company F and G. Company F was transferred to the 38th Arkansas Infantry Regiment. The few remaining men of the original Company G were transferred to Company K.

In late March 1864, the 10th was assigned to a brigade commanded by Colonel Simon P. Burns. Early April, union forces under command of Major General Nathaniel Banks' army. Union forces marching towards Shreveport, Louisiana, in the Red River Campaign, the 10th standing in the way under its assigned division commanded by General Parsons. Marching Pleasant Hill, Louisiana, the brigade took position to charge the opposing forces on April 9, 1864. Confusion ensued with a surprise attack by a counter attack against the brigade. By the time confederate forces rallied, Union forces retreated from the field. The battle cost the regiment 10 dead and 25 wounded.

The division went on the offensive, marching north towards Camden, to attack a garrison of troops commanded by General Frederick Steele. Federal troops fled, with Parson's division in pursuit. On April 30, the confederate division caught up with the union troops at Jenkins' Ferry. In a driving rain storm, confederate forces engaged the Federal troops, however, through the course of battle, the union forces largely escaped across the Saline River by way of pontoon bridges. Jenkins' Ferry conclude the 10th Missouri Infantry Regiment's wartime combat engagments, but not before enflicting yet more casualties; 3 dead and 8 wounded, including the death of Lieutenant Colonel Simon Harris.

The 10th wrapped up its war time experience in southern Arkansas and in Northern Louisiana. On June 8, 1865, the soldiers of the 10th Missouri Infantry Regiment received their paroles. Finally they boarded the steamer E. H. Fairchild for their return trip home.
