As a fan of SEE (when I found it, I actually read the corrected version so I did actually not find much discrepancies), I was wondering about that as well, even if it was somebody quite young from 3rd Reich, they would have been in H. Jugend (especially as a boy) and would have much of military knowledge to not leave any mark on Yod. So Yod would have trenches, camouflage, armour plates on wagons, firearms, chemical weapons, blips, and artillery many years in past and would not need Y. Perrinard. Especially in case of A. who also served in 1st WW.

Whoever they are, they are probably not who Ursula has been afraid to find. He would be 120+ in Earth years at the time this is happening (maybe less if we considered the cloning process to reset the cellular age of the transferee, but since the Epilogue of SEE does not mention what happened to others and Garia emerged, we do not know if that happens). That should be clearly too much even for Anmar healers (although he is dying after all). So I see there are 3 possibilities besides that I see immediately:

1. Somebody quite young (probably a girl) from one of the families of "Top brass" of 3rd Reich (maybe one of the poisoned Goebbl. children)? Having grown in luxury and not having direct military knowledge, but being indoctrinated with the "right ideals"?
2. Some child of one of those who fled to South America who grew on the propaganda of their parents?
3. Someone else entirely, probably a local Yodan, using a honorific title introduced by the real transferee (whoever that was), who was transferred to Anmar, spread all the the crappy supremacy ideas, but for some reason died before starting to build the military improvements for the empire? In that case Ursula will be probably very disappointed with all the work she put into this meeting.

Of course there is still the possible workaround that the memories were not really intact after a shoot through one's brain and the military knowledge was lost. But the VMBs would probably not make such error during transfer and it does not mesh with the "memory dimension".

I guess we will see soon anyway.

Well federation military, at least, fortunately it seems Pakmal is likely willing to part with the captured galleys, good test for a steam tug once available sometime after the rains. Yod is about what they probably expected, you have pockets of militant Ascendancy left scattered, turning to crime, but by in large, without their legitimacy, or means of contacting each other, they are isolated, and their civil backbone knows it's over. that isn't to say they aren't a threat, as they still have enough influence to rebrand and legitimize themselves when the Federation pulls out and tries to organize an election (implied as outcome in Snep's day out). Pakmal is more of a surprise and a potential diplomatic concern, being on the opposite bank to one of the Federation members they can't ignore them.

before the rains (as it is at this point in the story) the water levels are at their lowest, but both their vessels are meant to be able to navigate shallow waters, Ptuvil as a river barge (lightly loaded now as converted into a passenger transport) and the Visund being designed to land on beaches, probably not much further than Bidek though on this voyage, there are other concerns.
