[HELP] Books on german Great War poems

My gf has just read First World War Poems from the Front by Paul O'Prey, which is an antollogy of english poems written from the front, it's amazing, heart-crashing and she loved it.

​

She asked me if there could be books like these from the german (or any other) perspective and I thought it could be an amazing gift for her birthdat. Sadly, I've only found Antology of First World War French Poetry which we cannot read because... well, all poems are in the original french (we're Spanish and can read English pretty well). I have not had better luck with german poetry.

​

As an alternative to an existing antology, I'm thinking of compiling as much german WWI poems in English as I can find and print them together as a handmade antology, but I don't know where to start, I'd need at least half a dozen poets for starters..

​

TL;DR: Do you know some antology of German or French WWI poetry in English? Or some sources on particular german/french poets of the front?
