The American Army of Occupation now totals 1,188 persons, of which 1,043 are enlisted men, 117 are officers. 4 army nurses and 10 warrant officers. Though the normal capacity of the St. Mihiel is about 950 enlisted men and 50 officers, War Department officials believe the vessel will be able to accommodate the entire force when allowances are made for those who must be left behind in the interest of the Graves Registration Service and the sale of Government property.
General Allen will return on the St. Mihiel, but will leave behind a very small detachment to remain in charge of army property and arrange for its sale.
