New Orleans — The Louisiana Army National Guard’s 1st Battalion, 141st Field Artillery Regiment, will hold its annual wreath-laying ceremony and pass-in-review Saturday and Sunday in Metairie and Jackson Barracks in New Orleans.

The 1-141st of the 256th Infantry Brigade Combat Team, also known as the Washington Artillery, is the oldest and most historic unit in the Louisiana Army National Guard with roots that can be traced to a militia artillery battery in 1838.

The wreath ceremony was started in 1965 to honor the heritage of the Louisiana regiment’s past, while the pass-in-review dates from the early military history as a demonstration of the strength of assembled troops.

The wreath-laying ceremony will be 10 a.m. Saturday at Lake Lawn Cemetery, 5100 Pontchartrain Blvd.

The annual pass-in-review ceremony will be at 10 a.m. Sunday at Jackson Barracks, 400 St. Claude Ave.
