In early 1863, Company C of the 12th Ga Batt. was detached to Georgia Siege Train, under the command of Major Buist, and would remain with this command until September of 1864, when they rejoined the rest of the 12th Ga Batt in Virginia.
Also in January of 1863, Company E was detached to support the defense of Fort McAllister and would remain there until November 1863, where it rejoined the command in Charleston.
Perhaps since these two companies were detatched from their main command for so long they were issued seperate flags? I bet that flag in MOC Belonged to one of these companies.
Other things I've found on the 12th Ga Batt and their flags are the following:
On Oct 18th 4 companies of the 12th Ga Batt (A,B,D, and F)were sent to Fort Sumter where the fort was under constant heavy bombardment. On Oct 31st the garrison flag was hit several times. Each time it was replaced by Sgt W.M. Hitt and Pvt. Bob Swain of Co.F. Finally, the flagstaff was completely shot away, and they put up the 12th Ga Batt colors in its place. The 12th Ga Batt Band then mounted the parapet and played the "Bonnie Blue Flag". The Union forces stopped the shelling from Cummings point, formed their band and played "The Star Spangled Banner"
At Cold Harbor, their colors were described as having the battle honors "Battery Wagner" and "Fort Sumter" on it.
I wonder if this was a Charleston Depot Flag?
At the battle of Monocacy Md. on July 9th, 1864 the 12th Ga Batt lost six color bearers.
At the Battle of Cedar Creek, on Oct 19th 1864, the color bearer of the Battalion was killed trying to rally the men. Private Albert Wallen, who was 15 years old, ran back and got the colors while under heavy fire and brought them off safely. Described as the bravest boy in the battalion and was Complimented by General Gordon and General Lee for his bravery.
On March 25, 1865, at Fort Stedman the 12th Ga Batt lost its colors. These colors are at the Georgia Capital.
Hope this is of some help, I to have a great interest in the 12th Ga Batt. My GR-GR Grandfather was Pvt Absalom Rhodes of Co. F. He served from 5/62 until the surrender at Appomattox.
I would love to see some pictures of these flags!
