Campaign: Joint Operations against New Madrid, Island No. 10, and Memphis (February-June 1862)
Outcome: Union victory
This marked the first time the Confederate Army lost a position on the Mississippi River in battle.
The struggle for navigation control of the Mississippi River began as soon the Civil War started in April 1861. In February 1862, Union leaders aimed to
take control of the Mississippi River at Island No. 10, which sat between New Madrid, Missouri, and Tiptonville, Tennessee. Once they had control, the Union
could then move rapidly into the South and divide the Confederacy in two.
On February 28 the two sides clashed. Soon Union forces laid siege to Confederate-controlled New Madrid. By March 13 the city fell and Confederate troops
evacuated to Island No. 10 and Tiptonville.
The battle continued as Confederate troops were bombarded by Union vessels. Two U.S. Navy ironclad gunboats aided a Union Army river crossing to trap
Confederates trying to flee Tiptonville. The Confederates in Tiptonville and the remaining garrison on the island realized their cause was hopeless. The
Confederate forces surrendered on April 8, 1862.
The 8th and 15th Wisconsin Infantry regiments and 5th, 6th and 7th Wisconsin Light Artillery Batteries were heavily involved in this effort.
Early in the siege, the three Wisconsin light artillery batteries were positioned on the river bank just 800 yards from the fortress at New Madrid. They
bombarded it steadily until the enemy withdrew. The 8th Wisconsin Infantry helped capture 6,000 Confederate prisoners on April 8. The 15th Wisconsin
Infantry, composed almost entirely of Norwegian immigrants, was put in command of the island after the battle.
