The order to the army is published from the War Office:
HORSE GUARDS, Dec. 18, 1861.
_Orders for the Mourning of the Army for His late Royal Highness
the Prince Consort._
The General commanding-in-chief has received Her Majesty's commands
to direct, on the present melancholy occasion of the death of
H.R.H. the Prince Consort, that the officers of the army be
required to wear, when in uniform, black crape over the ornamental
part of the cap or hat, over the sword-knot, and on the left
arm;--with black gloves, and a black crape scarf over the sash.
The drums are to be covered with black, and black crape is to
hang from the head of the colour-staff of the infantry, and from
the standard-staff of cavalry. When officers appear at Court in
uniform, they are to wear black crape over the ornamental part of
the cap or hat, over the sword-knot, and on the left arm;--with
black gloves and a black crape scarf.
A like order was issued by the Admiralty, addressed to the officers and
men of the Royal Navy.
