My golden Else! This day is very hard for me. The 21st August; your birthday! It is the second time that we are not together on your birthday! My heart aches so much! The longer the time of our separation, the more I long for you and I would almost say that in my highly stressed state the present day causes me virtually physical pain. During the recent weeks I have tried to convey my wishes to you in various ways, let us hope that they reach you in time. Today I have written an additional postcard which is unlikely to arrive before October. And the wishes, which I am depositing here in my "letters", I will bring to you only when I come back. Do you understand that I cannot write much today? Little mouse, my heartaches! This day is all yours! I embrace you and kiss you a thousand times with all my love!
21st August, 1915
