Flag Description
The yellow flag with the green H was
adopted as a hospital flag by the US Army under a General Order
issued on 4 January 1864. Prior to that, as far as I can determine,
the only flag used was a plain yellow flag. I don't believe that
the CS Army ever used anything other than the unmarked yellow
flag as a hospital flag.

Regulations for Union and Confederate Armies
The Ambulance Department and Hospital Department were separate departments in the U.S. Army until 1864. (General Orders No. 9 Adjutant General's Office, War Department and Public 22-Act of Congress and General Orders No. 106 War Department, Adjutant General's Office). The Ambulance under the Quartermaster General and Hospital under the Surgeon General, U.S. Medical Service, War Department. It is not clear but it is probable the same system was used in the Confederate Army, except the Confederate had a Chief Surgeon over the Medical Service not a Surgeon General. (The Army Medical Department 1818-1865 CMH Pub 30-8, GPO S/N 008-029-00152-7)
U.S. Ambulance Department:
U.S. Army Revised Regulations 1861 (P 736) " The ambulance
depot, to which the wounded are carried or directed for immediate
treatment, is generally established at the most convenient building
nearest the field of battle. A red flag marks its place, or the
way to it, and the conductors of the ambulance and to the wounded
who can walk"
U.S. Hospital Department / Medical
Service:
Army of the Potomac March 24, 1862 General Orders No. 102 "
The Hospitals will be distinguished by a yellow flag" Department
of the Rappahannock June 19, 1863 General Orders No. 53 repeated
General Orders No. 102 Army of the Potomac. Army of the Cumberland/Department
of the Cumberland December 19, 1862 General Orders No. 91 "Hospital
and Ambulance depots will be distinguished by a yellow flag, 3
feet square for the hospitals and for the principle ambulance
depot on the field of battle; 2 feet square for the lesser ones"
The same order was repeated on April 25, 1863 Department of the
Cumberland. Adjutant General's Office, War Department January
4, 1864 General Orders No. 9 "Hospitals will be distinguished
by yellow flags with a green "H" in their centers, larger
for General Hospitals, smaller for Field Hospitals, a smaller
yellow flag bordered with green for ambulances". Army of
the Cumberland/ Department of the Gulf April 26, 1864 "Field
and General Hospitals flags will conform to the General Orders
No. 62 announced by the War Department.
C.S. Ambulance Department:
Although most of the Hospital Department and Ambulance Department
records were destroyed by fire in Richmond Virginia in 1865, I
have found that the same U.S. Army regulations of 1861 were adopted
by the Confederate Armies: Army of the Potomac/Army of Northern
Virginia, Army of the Mississippi, Department of South Carolina,
Georgia & Florida. Army of the Mississippi March 14, 1862
General Orders No. 3 copied nearly verbatim the Revised Regulations
of the U.S. Army of 1861 for ambulance flags. Department of South
Carolina, Georgia & Florida April 5 1863 General Orders No.
53 same as General Orders No. 3 Since General Beauregard issued
both General Orders above, he was probably also responsible for
starting the same system of flags in the Confederate Army of the
Potomac/Northern Virginia in 1861 (War Department Register of
Captured Flags No. 253,258,250,257,312 and 328)
C.S. Medical Department/Medical Service:
The organization of the Confederate Medical Department/Medical
Service was identical to that of the United States Medical Department
in 1861. It is probable that the same system, use of yellow flags
to mark the location of hospitals. (The Army Medical Department
1818-1865). Confederate Veteran XIX, reunion announcement "Medical
Officers Army and Navy, C.S.A. - Our place of meeting will be
the chapel of the First Presbyterian Church, centrally located
and easily accessible by the display from the front of a yellow
flag, the hospital insignia of the Confederate Army". Confederate
Veteran XXII " Dr. Simon Baruch, remembers the day of His
capture at the Black Horse Tavern Field Hospital on the Hagerstown
Road, I directed the Union Adjutant General's attention to the
yellow rag on the lightning rod and said; you fired five shells
after that hospital flag was hoisted"
The use of the yellow flag in the U.S. dates back to 1700's. The flag was used as a quarantine flag for ships suspected of carrying contagious disease. "An act to prevent Sickly Vessels from Coming into this Government" City of Philadelphia 1699. A yellow flag was also used to mark the location of hospitals in the "Marine Hospital Service" July 16, 1798 Federal Public Health Law "An act for the relief of sick and disabled seamen" signed by President John Adams. The hospitals of the "Marine Hospital Service" was under the Department of the Treasury at that time. At the start of the Civil War (War of Northern Aggression) as a Federal enterprise, "Marine Hospital Service" operated 27 hospitals. By comparison, the U.S. Army had 98 medical officers, 20 thermometers, 6 stethoscopes and a few medical text books. The Confederate Medical Department had 24 medical officers. In 1864 the "United States Marine Hospital Service" only had 8 hospitals in service, the others had been transferred to the U.S. Army Medical Service and the southern hospitals were taken over for military use by the Confederate Medical Service.
Except for the Federal Armies listed it is probable that the other Armies (Army of Ohio, Army of the West, etc.....) used the system of red flags to mark ambulance depots and yellow for hospitals until 1864 ( General Orders No. 106)
The Act of Congress of 1778 "Establishment of the American Army" and the Act of Congress 1778 & 1780 'Regulating the Hospitals of the United States of America" establish that each battalion of infantry (infantry regiment) of the Army have a Surgeon and a Surgeons Mate. It is probable that from 1818 to 1860 or 61, the regimental surgeon and/or brigade surgeons had a flag with a green or yellow device ( Corps Badge etc...) to mark his position in the field. ( U.S. Army Medical Department Museum has a pre or early Civil War Medical Flag - white field with a green shamrock in the center and a green border similar to 2nd U.S. Army Corps Division Headquarters Flags)
(Note: the National Archives has artwork of a yellow flag with a green "H" in the center on the hoist upper and lower corners a small red cross, Petersburg, Virginia Field Hospital 1864)
