World War I postcards

[fridgeman]

Hello dear Feldgrau members. I could need help in making out the back text of these very old postcards.
My grand-grand-grandfather wrote them during ww1, and the pencil written text is hard to make out nowadays.
I know some lines are impossible to read, but maybe someone has a tipp how to make the text reappear,
or can do some tricks with a photo program to make the text better to read. The adress and name
i'm able to read, but not the messages. I hope you like the postcards!

As always, glad for every bit of help!


Here is the link to the scan of the written text i need to make out (high res):

This is what I thought I could read, perhaps others can correct it.

Dear Gertrud!
Perhaps your wish did come true,
but did not work out too well.
Greetings from my heart,
see you again.
