Origin/meaning

The regiment was organized in 1861 and was in the First Division of the 14th Corps, Army of Cumberland, during most of its operations during the Civil War, the badge of which was a red acorn.
The prominent feature of the Confederate flag was the saltire cross. The crossed arrows represent the regiment's Indian campaigns.
The old 8th Corps badge of the Spanish War recalls the Philippine service during the Spanish War and the bolo for the operations in the Visayas.
In World War I the regiment was awarded the fourragére for its part in the Soissons offensive of 1918-07-18, and the operations of early October around Exermont and Hill 240 in the old Lorraine.
The chief bears the bend of the arms of Lorraine between the fleurs-de-lis of the arms of Soissons.

The coat of arms was originally approved on 1922-04-24. It was amended on 1923-09-10 to correct the history.
On 1924-04-16 it was amended to correct the wording of the blazon. The coat of arms was amended on 1939-02-16 to change the color of the acorn in the crest
from Azure (blue) to Gules (red) and change the description accordingly.
