The 10th Texas Field Battery was organized on March 1, 1861. The unit was raised by
Captain Benjamin H. Pratt, a
Texas railroad builder. When the battery was mustered into
Confederate service in
Jefferson, Texas, it contained 72 men drawn from
Harrison,
Marion, and
Cass counties. Marmaduke's raid saw Confederate cavalry strike into Missouri in hopes of distracting Union troops from more important areas and peaked with
an abortive attempt to capture
Cape Girardeau, Missouri. From April 17 to May 2, Pratt's battery served in the raid, under Colonel
George Washington Carter. Two guns of the battery were part of a force sent to strike
Patterson beginning on April 19 at midnight, and while the battery was present on the field at Cape Girardeau, it was only lightly engaged. After the raid failed due to the repulse at Cape Girardeau and the arrival of Union reinforcements, Marmaduke's men concentrated on
Crowley's Ridge in early May. Still serving in Carter's brigade, the battery, which was now armed with four cannons, moved to
Colt, Arkansas, (then known as Taylor's Creek) as part of a plan to capture a Union cavalry force operating in the area. Early on May 11, Carter's men made contact with the Union cavalry, bringing on the
Skirmish at Taylor's Creek. During the action, Marmaduke detached two of Pratt's cannons to the south, as he was worried about Union reinforcements and wanted to protect the center of his line. After a brief skirmish, the Union cavalry retreated, but were able to escape as Carter did not order a pursuit. The battery then returned to operating against river shipping, this time both on the Mississippi River and the
Arkansas River. When
Confederate troops abandoned the city of
Little Rock, Arkansas, on September 10, Pratt's battery was at the Arkansas River, where it covered the crossing of the retreating Confederate units. The main part of the battery covered a
ford, while a smaller portion was sent to support
Etter's Arkansas Battery. Both Etter's guns and the detachment from Pratt's battery were soon silenced by Union
counterbattery fire. Later that day, in the
Battle of Bayou Fourche, Pratt's battery, which was armed with
12-pounder howitzers at this time, supported Colonel
Robert C. Newton's cavalry with artillery fire. When Marmaduke moved against the city of
Pine Bluff, Arkansas, in October, Pratt's battery accompanied him. On October 24, Marmaduke readied his forces to begin moving towards the city and its Union garrison. Near the
Saline River, the Confederate force split to conduct a
pincer attack. Pratt's battery was part of Newton's wing of the Confederate force, as part of
Major B. D. Chenoweth's brigade. Early on the 25th, Newton's cavalry reached a
brickyard southeast of Pine Bluff, where they dismounted and waited for the other wing of the Confederate force to fire a signal shot, which would begin the
Battle of Pine Bluff. Once the shot was fired, Newton's men, led by
Wood's Missouri Cavalry Battalion, charged the town, but were halted by Union defenders. Pratt's battery was then deployed to fire on Union
sharpshooters deployed in houses; the defenders were driven back further into the town by the fire. The Union soldiers were eventually driven back into a barricaded position in the
town square. Pratt's battery was brought up to fire on the position and particularly Union troops in the
cupola of the courthouse. While the courthouse cupola defenders were driven out of their positions, the main Union barricades held.
Ruffner's Missouri Battery had been firing from a churchyard, and Pratt's battery joined the Missouri gunners in that position. The Union position could not be subdued, and Marmaduke believed that a frontal attack would be too costly, so the Confederates abandoned the town in the mid-afternoon. The battery then spent the winter of 18631864 stationed in northeastern
Louisiana. Beginning on May 23, 1864, the battery accompanied a force of Missouri cavalry led by Colonel
Colton Greene to a landing on the Mississippi River in Arkansas, where it fired on several transports through June 4. The intention was to disrupt the portion of the Union supply line dependent on the Mississippi River. At this time, Pratt's battery had six cannons. It was split into multiple detachments in order to maximize disruption of river traffic. On May 24, the battery dueled with the gunboat
USS Curlew for about half an hour before withdrawing, and it fought other skirmishes with elements of the Union Navy and the
Mississippi Marine Brigade. When Union forces responded to Greene's harassment of river traffic by landing a sizable infantry force near the Confederate position on June 5, the Confederates withdrew and Pratt's battery covered a bridge during the
Battle of Ditch Bayou, which was fought on June 6. At Ditch Bayou, the Confederates held off Union forces for some time before withdrawing when they ran out of artillery ammunition. The Union troops were unable to mount an effective pursuit. ==Price's Raid==
