who helped collect large amounts of money for the colonial army and what was the nickname?

Since this is not my area of expertise, I searched Google under the key words "US Revolutionary War finance" to get these possible sources:

http://books.google.com/books?id=Uazpff00Y5EC&pg=PA77&lpg=PA77&dq=US+Revolutionary+War++finance&source=web&ots=n-GnPzVamM&sig=LZaT12_ZceamZuWwkxZZTzKJzjs&hl=en&sa=X&oi=book_result&resnum=3&ct=result

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps. Thanks for asking.
