Sorry; I meant the troops recruitable in a single site. Aren't these carried over when the capital falls? I was under this impression myself, but that mostly comes from toying with special sites as I do not take capitals that often.

One way or another, before 2.13 Black Forest Ulm units coming from their home sites were not working as intended. So either you can recruit them in 2.13, or you could recruit them in 2.12. That is according to the bug fixes for the 2.13 patch, which states that "Ulm black forest home site units not recruitable by others."
