Would you say there's a decent chance Katte's last letter to his father, written at Küstrin and passed on to Müller to be passed on to Schack to make a clean copy, ended up in the archives at Berlin? And do you think there's a chance foreign envoys would have access to less sensitive material, like personal farewell letters, from the archives?
I think the fact that the envoy reports include the "Fritz has renounced his right of succession" error but the correct info that his father pressured him to certainly hightens the likelihood the Danes had at least one person with access to all that material, including correspondance to and from Küstrin, in their pay. Possibly someone who delays potentially state endangering intel - like the demand on Fritz to remove himself from the succession only being mentioned when it is, in fact, no longer made.
And yes, I think all the letters Katte wrote to familiy members were copied first before behing delivered.
