Croatian anecdotes, facts, journals, letters, etc., from World WarOne

Josip Novakovich, author of Salvation and Other Disasters, is looking for 
Croatian anecdotes, facts, journals, letters, etc., from World War One, as 
research materials for a novel he is working on. He is writing about Croatian 
immigrants in the States, their work in coal mines, iron mills, factories, 
etc., their reactions to the war, and their experiences in the war both as 
draftees and volunteers for either side. He welcomes any tidbits of 
information--please send to josipn@yahoo.com.
