US War Prison Barracks No. 2
During World War 1, Fort Oglethorpe was the largest German internment camp in the US. Its official title was the US War Prison Barracks No. 2. For three years (1917-1920), the US held about 3,600 prisoners that were mostly German sailors of interned vessels in American harbors, and German nationals who had been living and working in the US prior to the war. They were held behind barbed wire with no rights, no sentence, no trials, and few freedoms. This controversial practice of jailing "dangerous enemy aliens" or "terror suspects" during wartime in the name of national security would play out several more times over the next century. The Fort Oglethorpe experience was really the first test of our nation's values as a free democratic republic.

What did the Prison Look Like?
All matters of the US War Prison Barracks during WW1 were matters of national security, so information is limited at best. We have the local newspaper reporters and a few photographers to thank for what little information we do have. Nevertheless, we can piece together the scattered scraps of information that they left behind to get a fairly good idea of the prison camp.
​
​Based on newspaper research, the prison stockade was 31.5 acres, more or less a large square. It was situated about a half mile north northeast of the original Fort Oglethorpe post (Barnhardt Circle). While Fort Oglethorpe was located on the west side of the Lafayette Road, the prison stockade was located on the east side of the Lafayette Road. Today, the stockade would be bounded by GA Hwy 2/Battlefield Parkway on the north, Lafayette Road on the west, and Forrest Road on the south, and the Gilbert-Stephenson Park at its southeast corner.
The perimeter of the stockade was an inner and outer fence. The two fences were about 10-15 feet apart and about 10-15 feet high. The six-foot zone just inside the inner fence was known as the "dead zone," because anyone in that zone would be shot. The fences were barbed wire strands about four inches apart, running parallel to the ground, and attached to wooden posts.
Twelve guard towers were evenly placed along the west, north, and east sides, but none on the south side. The reason for this may be because the prison stockade was adjacent to the Camp Greenleaf medical school, which was between Forrest Road and what is today Reeds Bridge Road. Each guard tower was armed with a mounted machine gun and a pump action shotgun. Each tower also had a searchlight and telephone. If the twelve guard towers were evenly spaced along the west, north, and east sides of a 31.5 acre square, they would be approximately 78 yards apart. A wooden boardwalk went around the entire stockade connecting the guard towers, and guards were walking the perimeter frequently. The towers and boardwalk were just outside the outer wire fence. Nitrogen lights were used around the perimeter to illuminate the fences.

By zooming in on the picture below, one can see the barbed wire strands and the construction of the fence, as well the guard tower. In the background is the Lafayette Road, so this picture is looking at a guard tower on the western side of the stockade. The overhead wires would have been carrying power from Chattanooga and some are telephone wires (courtesy National Archives).

Below is a close up of the stockade's main gate which was located near the southwestern corner. Zooming in on the fence clearly reveals the barbed wire. Note the top wires spaced closer together. Also note the personnel gate that one guard has opened and the other guard is walking through is a portion of the larger gate through vehicles could pass (courtesy National Archives).

The picture below is a good wide angle shot from the Lafayette Road looking east toward the stockade. Note the spacing of the guard towers. Outside the stockade in the grassy areas, it appears American troops are perhaps training. There appears to be what might be a baseball game going on in the center-right. The rock quarry where prisoners harvested rock for use in camp improvements is in the center, but located outside the stockade. The two rail tracks in the foreground were electric trolley tracks built in 1917, to accommodate transportation between Chickamauga Park, Fort Oglethorpe, and Chattanooga. Remnants of that line can still be seen today around Missionary Ridge (courtesy National Archives).

Film Footage of the Prison Barracks
Below is a wartime silent film with footage of the Fort Oglethorpe War Prison Barracks No. 2. It opens with footage of War Prison Barracks No. 1 (Fort McPherson, Atlanta, GA). The Fort Oglethorpe segment begins with the American sentry in the guard tower and ends with Germans digging in their gardens. The reader will know the Fort Oglethorpe segment has ended when they see the scene of civilians loading onto a ship in Charleston, SC, which was a large deportation of German prisoners after their release. The film ends with Americans inspecting a trophy German submarine (U-117) after the war was over (film courtesy National Archives).

The German Experience at Fort Oglethorpe
The German prisoner experience during World War 1 at Fort Oglethorpe is vast. To keep things simple, the author has divided this experience into the following periods:
-
Pre-Hot Springs transfer - October 1917 - August 1918
-
Post-Hot Springs transfer - August 1918 - June 1919
-
Post-Treaty of Versailles release - June 1919 - April 1920
​It is important to note that the battlefield combat of WW1 ceased with the Armistice on November 11, 1918, and the official end of WW1 was the Treaty of Versailles, signed on June 28, 1919, yet prisoners continued to be held for ten months after the official end of the war.

The below timeline was created to illustrate key local and world events, escape attempts, the camp census over time, and who the camp commandant was. ​The date markers are relative and not to scale.
