From Bergeron, LA Confed. Units, 14, 24-25:
Washington Battalion
"Probably the most famous Louisiana unit in the Confederate army next to Wheat's Tiger Battalion, the Washington Artillery traces its lineage back to 1838 in the state militia. ..."
5th Company
"Transferred to Confederate service March 6, 1862, with about 160 officers and men, this battery moved to Jackson, Tennessee, to reinforce the army of General Pierre G. T. Beauregard. Assigned to the brigade of General J. Patton Anderson, the battery played an important role in the Battle of Shiloh, April 6, by driving the Federals from some of their camps and bombarding the enemy soldiers trapped in the Hornet's Nest area. Three guns participated in a skirmish at Monterey, Tennessee, April 29. Two guns fought in the engagement at Farmington, Mississippi, May 9. Transferred to General Daniel W. Adams's (later Randall L. Gibson's) Louisiana brigade, the battery accompanied the Army of Tennessee on its invasion of Kentucky in September. The battery fought in the Battle of Perryville, October 8, losing two caissons. In the Battle of Murfreesboro, Tennessee, the battery was only lightly engaged until January 2, 1863, when it supported an attack against the Federal left flank. The men went with the brigade to Jackson, Mississippi, in May and fought in the campaign there, July 5-25. Returning to the Army of Tennessee, the battery fought in the Battle of Chickamauga, September 19-20; about 33 of its men were killed or wounded. The men participated in the Battle of Missionary Ridge, November 25, and lost their guns to the Federals during the retreat of the army. At Dalton, Georgia, the battery received four new guns in early 1864. In the Atlanta Campaign, the men frequently engaged the enemy. Three of the battery's guns became disabled during the fighting at Resaca, May 14-15, and Dallas, May 26-28. After the battles around Atlanta in July and August, the battery accompanied the army on its invasion of Tennessee. Assigned to General William B. Bate's division, the battery participated in operations near Murfreesboro. The men repulsed a charge by enemy soldier's on December 4 but lost two guns to the enemy on December 7, when the horses were killed. In February 1865, the battery received orders to report to Mobile, Alabama, to man heavy artillery emplacements there. The men moved to the Spanish Fort defenses in March and fought in the operations there from March 27 to April 8. After the evacuation of Mobile, the battery again received some field pieces and went with the army to Cuba Station. The battery was at Meridian, Mississippi, at the surrender, May 8, 1865. During the war, approximately 382 men served in the battery. Of that number, 43 were killed in battle, 1 died in an accident, and 6 died of disease."
