Captain James C. Hughes photographed these men of the 344th Field Artillery Regiment, March 20, 1928. He mentioned Captain Stanley in his caption to the photo, perhaps he is the officer seated in front of the rest. They were probably taking part in ORC (Officer Reserve Corps) at Waco, Texas, as Captain Hughes had gone from ORC duty in Houston to Waco, Texas and was there from December, 1927 to July, 1929. James Clark Hughes was born in Topeka, Kansas, in 1888, and served in the Mexican Border Conflict, World War I, and World War II. He used an autographic camera to take pictures of friends, family, and places in the United States and Europe during and just after World War I.
