The 141st Field Artillery Regiment (Washington Artillery) is a United States field artillery regiment. History The 141st Field Artillery is an historic American military unit that is currently part of the Louisiana Army National Guard headquartered in New Orleans, Louisiana. It traces its lineage to a militia artillery battery back to 1838, and its heritage includes substantial combat service in several major wars. It earned the Presidential Unit Citation (US) for its service in World War II. The Washington Artillery was founded on 7 September 1838, as the Washington Artillery Company. It received its regimental flag in August 1846 after serving under Zachary Taylor in the Mexican–American War. 26 May 1861 the Unit was mustered into the American Civil War; four companies served in the Army of Northern Virginia and a fifth was in the Army of Tennessee. Elements of the Washington Artillery participated in over sixty major actions. A few notable engagements include: Battle of Antietam, Battle of Perryville, Battle of Gettysburg, Battle of Shiloh, Battle of Chickamauga, Battle of Fredericksburg, First Battle of Manassas, and the Battle of Cold Harbor. After the Civil War, it was reorganized as an independent unit called the "Louisiana Volunteer Field Artillery" where it served the United States in the occupation of Cuba. It later was called into service to protect the Mexican border in 1916. A year later it received the designation 141st Artillery. In early 1941, the 141st Field Artillery was mobilized for World War II where it earned the Presidential Unit Citation; a duplicate unit was formed, the 935th Field Artillery Battalion, with both serving in Europe and North Africa. The anti-tank batteries of the battalion were separated in mid-1941, and formed the 773rd Tank Destroyer Battalion. On 1 July 1959, the 141st and 935th Field Artillery Battalions were consolidated with Headquarters and Headquarters Battery, 204th Antiaircraft Artillery Group, 527th Antiaircraft Artillery Battalion, and the 219th Antiaircraft Artillery Detachment to form the 141st Artillery, a parent regiment under the Combat Arms Regimental System to consist of the 1st, 2nd, and 3rd Howitzer Battalions, elements of the 39th Infantry Division, the 4th Automatic Weapons Battalion, and the 5th Detachment. The 141st Artillery was redesignated on 1 May 1972 as the 141st Field Artillery to consist of the 1st Battalion, an element of the 256th infantry Brigade. It was withdrawn 30 June 1986 from the Combat Arms Regimental System and reorganized under
