Searching for Photographs of the 15th Infantry Regiment in 1864

[Max Rasmussen]

My 2x Greatgrandfather Niels Christiansen from Slagelse, served in the 6th Company of the 15th Infantry Regiment during 1864. I would like to find a photograph of that regiment. I have searched the internet and found pictures of other regiments, but not 15th.

If anybody has such a picture or can direct me to one on the internet, I would be most apreciative.

Niels younger brother Jacob Christiansen, also served in the war (as a Stillingsmand) in the 1st Company of the 12th Infantry Regiment, so any pictures of this would be helpful too.
