U.S. Army Order of Battle

From World War I Document Archive

A peacetime order of battle of the United States Army for August of 1914 (the outbreak of the World War in Europe), listing the divisions, brigades, regiments, and battalions of infantry, cavalry, field artillery, coast artillery, and engineers with their permanent garrisons and actual locations, all down to the company, troop, and battery level. All quartermaster, ordnance, signal corps, medical, and staff troops and units are included. Complete coverage of both the Regular Army and the National Guard. From the cavalry on the Rio Grande to the Philippine Scouts, from Rhode Island coast artillery to the Military Prison on Alcatraz, from the Porto Rico Regiment to the Alaska garrison, all are named and located.

For regular army units, locations are also noted for April 1917, when the US finally did enter the First World War.
