Kosciuszko, leader and exile Book

Been trying to find some books on lesser known heroes of the American Revolution so got this from the library. Book was a huge slog, the vast majority of the content is 200+ year old letter from Pulaski, Washington and others of the times. Would have been a much easier read if the letters had been summarized into modern language. The story also only covers his arrival in America to his death with a little bit of the aftermath. Very little is said about his life in Poland. Also way too much of the book details the fight between two 18th century writers, one who loved Pulaski and one who hated Pulaski.
