Do you have any of your haiku to share, as you mentioned they touch on the darker moments?
The book which I have somewhere in my library is:
Haiku Iz Rata: War Haiku, second edition. Marijan Čekolj, editor. Croatian Haiku Society, Smerovišće 24, 41430 Samobor, Croatia, 1995, 80 pages, 8 x 5½ inches, paperback, perfectbound. In Croatian and English.
If you particularly like war haiku, then check out this list:

too early for sunrise
the horizon glows with the red
of burning villages
This ku wowed me!
Amazing.
Thank you for posting these great examples, Alan 
Do you by any chance know where i would be able to purchase a collection like this?
I would be very interested.
