GENERAL ORDERS, ) WAR DEPARTMENT, '£ > Adjutant General's Office, No. 69. ) Washington, March 20, 1863. Paragraph 10 of General Orders, No. 36. of 1862, which authorizes the chief medical officer in each city "to employ as cooks, nurses, and attendants any convalescent, wounded, or feeble men, who can per- form such duties, instead of giving them discharges," is hereby modified as follows: At every U. S. General Hospital, the feeble and wounded men, unfit for field duty, but not entirely disabled, instead of being discharged, will be organized and mustered in detachments, under the charge of the officers acting as Military Commanders, who will assign men to them from time to time, on the reports of the surgeons in charge of hospitals. From these Invalid Detachments the Military Commanders will make details for provost, hospital, and other necessary guards; for clerks, hospital attendants, nurses, cooks, and other "extra-duty''' men. The Invalid Detachments will be mustered and reported as detach- ments, and will be paid on the Detachment Polls; but no extra pay will be allowed in any case. The Detachment Rolls must show to what company and regiment each man properly belongs, and all assignments to them must be promptly reported to their company commanders. They are not to be dropped from the rolls of those companies, but will be reported on detached service from them. Should any of the men become fit for duty with their regiments, they will be immediately sent to join them. In case of a want of non-commissioned officers to give efficiency to the Invalid Detachments, lance appointments maybe made, but with- out increase of pay. By order of the Secretary of War: L. THOMAS, Adjutant General. Official: Assistant Adjutant Gensral.
