This is kind of bringing a thread back from the dead, but i was looking though my Danish materials and came up with the following thoughts about the Danish uniforms in Ireland, so I thought I would share them, FWIW. Here is what I have been able to gather on the subject. If anyone has anything more specific, please let me know.
In his “Chakoten” article on the Danish Army 1699-1720, translated by Dan Schorr, Tortstein Snorrason quotes a Royal Decree of January 24, 1691 that shows the following colors:
Life Guards Yellow with Red lining
Queen’s Red with Yellow lining
Prins Frederick Gray with Dark Red lining
Prins Christian Gray with Yellow lining
Prins Georg Gray with Orange lining
Seeland Gray with Blue lining
Jydske Gray with Red lining
Fynske Gray with Green lining
In another article on the Scanian War on Dan’s old Northern Wars website, Olaf Hasselager and Snorrason show the following during the later years of the war.
Life Guards Red with Yellow lining
Queen’s Red with Yellow lining
Prins Frederick Blue with Dark Red lining
Prins Christian Blue with Yellow lining
Prins Georg Blue with Orange lining
Seeland Gray with Blue lining (1679)
Jydske Gray with yellow lining (1677)
Fynske Gray with Green lining (August 1677) (green with yellow in 1676)
These colors are the same as shown for 1679 in a typed manuscript study by Hasselager that I got from the Tøjhusmeet in the mid-1980s (not sure when it was written). All this research seems very thorough and reliable.
The Life Guards uniform was changed in 1686 to yellow with red. The Queen’s Regiment remained the same. The facing colors of the other regiments, with the exception of the Jydske regiment were that same under the 1691 decree and they were in the late 1670s. The obvious change is that the three “enlisted” regiments named after the princes were gray in 1691 instead of blue. It is also worth noting that the lining colors remained consistent, for the most part, through the early 1700s, until the uniforms were changed to red. See Hoglund et al., and Snorrason.
From the foregoing, it would seem a safe conclusion that the facing colors in 1690 were, with the possible exception of Jydske, the same as the late Scanian War. However, there are some sources that are inconsistent with that theory.
Vaupel shows Fynske in green with white in 1685 and this has been adopted by the artist in the Osprey book on the Boyne. Vaupel also indicates light green with orange for Prins Georg, but this has been said to be a misreading of his handwriting by the publisher and it should be light gray and orange.
An eyewitness describes the following uniforms of Danish infantry in Ireland in 1690(?) but does not state which regiments they are: green with red; blue with white; grey with blue; and gray with green. What are we to make of this? Green was the traditional color of the Fynske regiment (indeed it is referred to as “The Green Regiment” in reports to the King of Denmark from Ireland), and I have found no other regiment that ever wore green. Yet here we have a regiment supposedly with green coats and another with green linings. In 1676, one of the Fynske regiments wore green with yellow linings, but the two Fynske regiments were amalgamated after the Battle of Lund in December 1676 and every source shows that the regiment wore gray with green linings by the end of the war. I am inclined to believe that the regiment with gray coats and green linings was Fynske. True, there is some indication that Fynske wore green coats with white at some time in the 1680s but there is no indication that they ever wore green with red linings. So, perhaps the green with white reference is an inversion of white (gray) with green?
I am also inclined to think the regiment wearing gray with blue is Sjaeland, since those colors were worn by it in the late 1670s and thereafter.
So which regiments are green with red and blue with white? One possibility is that the green coats were actually faded blue (although it is usually the other way around) and the regiment was Prins Frederick. If one accepts that Prins Georg wore green with orage, it is possible the reporter described orange as red, but I theink this is unlikely. Likewise, the regiment with blue coats and yellow linings, might be Prins Christian, with the yellow having faded to a whitish color.
If the January 1691 decree actually required a change of uniform colors, as opposed to confirming the status quo for these regiments, it is unlikely that the changes were implemented while they were in Ireland, since there is every indication that there was difficulty in even supplying new recruits. It does seem likely that they would have been the colors worn after these units went to Low Countries.
Absent any evidence of a change in a unit’s flags between the Scanian War and 1690, I would use the flags used in the Scanian War. Any flags showing the order of the Elephant (a small elephant dangling from a blue ribbon or a chain) would not have been carried in Ireland, since the Order was not established until 1693. Also, any flag with an “F4” monogram would be WSS/GNW time frame, as Frederick IV became king in 1699. Christian V was king from 1670 to 1699 and his monogram was a “C” intertwined with a “5."
I'm certainly open to comments an corrections. Hope this is of help to those who want to paint the Danish contingent.
