The History of the 29th Wisconsin Infantry Regiment
The Twenty-ninth Wisconsin Infantry Regiment was organized at Camp Randall, Madison, Wisconsin, and mustered into the service of the United States Union Army on September 27th, 1862. The Regiment left the state on November 2nd, reaching Helena, Arkansas, where it engaged in operations in the interior of the state and expeditions up the White River, to Friars Point in Mississippi, and as far as Yazoo Pass.
The regiment left Arkansas on April 10th, in the movement against Vicksburg. Crossing the Mississippi River on April 30th the unit moved to the front and took part in the battle of Fort Gibson on May Day. Serving under General Grant the regiment engaged in the battle of Champions Hill on May 16th, and then took position in the trenches in the rear of Vicksburg, and continued on in the siege until the surrender on July 4th, 1863. The day after the surrender the 29th was detailed to take part in the Jackson Campaign, running from July 5th to the 25th. In August accompanying other forces, it occupied Natchez, Mississippi, and from there moved into southern Louisiana. It was engaged in many expeditions about New Iberia, and in the early part of January of 1864, joined an expedition to Texas on the Rio Grande, returning to New Orleans by the end of February.
It was next assigned to duty with the forces engaged in the Red River expedition, March 10th-22nd, 1864, and participated in that campaign, and saw action in the battle of Sabine Cross Roads on April 8th, 1864. As a part of the work of the Twenty-ninth in this campaign it assisted Colonel Bailey in constructing a dam across the Red River which saved the Union gun boats. After the abandonment of the movement the regiment was transferred to southern Louisiana where it remained until September. Then the unit was transferred back to Arkansas, with headquarters at Little Rock, from which the regiment accompanied many expeditions in frequent contact with the enemy.
In January of 1865, the Twenty-ninth was again ordered to New Orleans as a part of the forces collecting for the reduction of the fortifications at Mobile, Alabama. This campaign lasting from March 17th to the 4th of May in 1865. It included the reduction of Spanish Fort and the capture of Fort Blakely. The war being practically over, the regiment remained in southern Louisiana until the 22th of June, when it was mustered out of the service of the United States, returning to Madison, and was disbanded on July 17th, 1865.
