I think you are both correct. At moment I thought that those lines 'must' have been written by the Empress actually, since that spirit of writing, so poetic and full of hope really reminds me on the Empress' letters from 1917. I must admit that I even thought that letter contains more of them.
Empress' diary , May 2/15 1918:
Wednesday. ... They were told not to leave the house this morning. The old man removed a white paint all the windows from the outside, so that only the top you can see a piece of the sky, and it looks as if we were in a thick layer of fog, not quite comfortable. Breakfast. Sedinev feels bad and he is wheezing. N. read to us. We were allowed to go into the garden for an hour. N. again read, we played bezique ... Dinner. Cards. Sedniev's inflation. [temperature] 38,6.
