Dear Bernard
I thought this article on the Colonial Black Marines and their role at Bladensburg might be of interest. It seems like the Royal Navy did the Emancipation Proclamation 50 years early. I was only aware recently that Keys in his Star Spangled Banner Poem had a line about “No Refuge for the Hireling and the Slave” left out. We British being the Hirelings and Colonial Marines as they were escaped Slaves Regards
