I risk a translation of Chebotareva's diary entries about our thema. If someone will have time to do better later, I will be grateful! Just as an introduction!

What's for a drama had Olga Nikolaevna? Why is she so thin, so white? Loves Shakh-Bagov? Yes, a little bit, not it is not so serious. In general, the atmosphere is at the moment not very quite. As soon as she finishes her work, Tatiana Nikolaevna goes doing the injection and them they sit both with K. The last sit at the piano and, playing something with one finger, talks endless, a lot with our sweet girl. Varvara Afanassevna looks at it with horror and said that if Narishkina, madam Zizi, would see these scenes, she would certainly die. Shakh-Bagov has temperature, he is lying. Olga Nikolaevna sit all the time on his bed. The other pair came to them, they all sat on this bed yesterday and looked at albums. K. is doing his best. The sweet face of Tatiana Nikolaevna hide nothing, she is rose, exited. But it is not good, all these attouchements. I think it is horrible. The others are actually jealous and I can imagine what they say in the town. Vera Ignatevna will send K. to Eupatoria, thanks to God. Let us keep them far from sin. Vera Ignatevna said me she heard that Shakh-Bagov, when he was drunk show someone ON's letters. The poor children!

27.11 (...) at 9pm came ON and TN to clean the instruments. K. once more sat near Tatiana Nikolaevna on the stairs. The children were in a good mood, exited.
(...) The empress gave an order, K. can stay as a sanitar.

24 they succeeded in coming to us, with the secret idea to see K! We decided to send to Eupatoria the 18. He allowed himself some incredibles things, somewhere he talked about his victory. People make gossip, they see how he takes her endless far from the others, playing something on the piano and endless talking something in low voice with mysterious expression. Vera Ignatevna is totally angry.
22 on the evening both of them, Shakh-BAgov and K. were invited by Anna Alexandrovna, there was also the Empress. She decided that K. can stay until the end of the fests. They are today out, out of the lazaret. What will be?

Tatiana Nikolaevna asked what related O. who just came back from Eupatoria.She evidently waited hearing something about K. "They all go for only 6 weeks", she asks. I heard that K. will be back those days.

The 3rd of March the Emperor came back to the army. They (ON and TN) came very early, and had to go to say good buy at 12 o'clock. The day before were, evidently, others plans. K. was sure that they will come back after the train. At 12.00 they phoned, called Rita, and then, of course, K. I was in road (...) and saw (...) K. On the left I heard the sound of their car and saw their pretty faces. I could not understand how did they could go out at that time. They had the permission to go to the cemetery. "We had such a desire to see K. , we came by car to the door of the lazaret and then went to the cemetery.
