This picture is Officers Training - Camp John Sevier - May 1914 - My grandfather Joseph Phillips is Bottom Right fourth from left. According to military history "Camp Sevier (South Carolina) was initially established in July 1917 to train draftees and recruits from South Carolina, North Carolina and Tennessee."
This was evidently a predecessor in or near Maryville, TN. I have found on this website, Knox County in the World War the following:
In the fall of 1918 the regiment (Fourth Tennessee Infantry) was ordered to go into encampment at Camp John Sevier near Fountain City. The rifle range was put in a good state of repair, the camp buildings and grounds prepared, and all arrangements made for the encampment October 7-22, 1918. The serious epidemic of influenza, which reached its height about that time, made it necessary to call off the encampment. After the signing of the armistice, Colonel Chapman resigned his command on November 23, 1918, and serious attempts to continue the military training with the companies were abandoned.
The catalyst for the war that plunged nations into its first major World War was the assassination of the heir to Austria's throne, Archduke Francis Ferdinand and his wife, the Duchess of Hohenberg on June 28, 1914 by Serbian anarchists.
My grandfather had been discharged in 1899 from the U.S. Army because of Malaria and therefore could not reenlist for WWI
