Us american pilot Volunteers during the polish-bolshevik war 1920

As the titel speaks for itself, could you do maybe a special about us pilots in the polish-bolshevik war from 1919-1920??

Greetings from cologne


The only Name i know, who was definitely in the 7. Fighter sqn, is Kpt. Merian Cooper. The whole 7. Fighter sqn was, as far as Iā€™m aware, formed from us volunteers. And that is all I know.
Being Polish, I would like to know why risks some one his life for a country he never been to.
