Qwerty I directed that part of my part to Arso.
Basically that part of the story is part of the mesora so to
Speak of the retelling of what happened every year so it’s not forged…
In any case, for context, the Alter Rebbe was still in petersberg when he was released (not home), he had given the soldiers the address of a chossid living in the city, where all the Chassidim were expecting him. The soldiers brought him there but to the downstairs apartment which belonged to a misnaged. The misnaged welcomed him in and gave him a cup of tea, but then started lecturing him for an hour over the changes he had made. He wasn’t interested in hearing a true answer, he just lectured the Alter Rebbe. Eventually the Chassidim realized what might have happened and went downstairs where they heard the misnaged yelling at the Alter Rebbe. The knocked/ banged on the door, he opened and said here’s your Rebbe, take him. The Alter Rebbe finished the tea that has been offered in honor of his host and then left.
