British Political Satire - A Minister in Arms

This satire, according to the Library of Congress:

...expresses the British view that the American Revolution was inspired by the same kind of religious fanaticism that had fueled Oliver Cromwell's establishment of the Commonwealth of England more than a century earlier. Among the ragtag American soldiers is a clergyman holding a flag with a Liberty Tree on it and claiming "Tis Old Olivers Cause no Monarchy nor Laws."
