Colonel Darnall has rendered especially meritorious and distinguished service in organizing, developing, and administering the Supply Division of the Medical Department, and it is due to his foresight and ability that new sources of medical supplies were developed in this country so that adequate quantities of material were always available for use with the sick and wounded of the Army.
