As you may know, the 244th Birthday of the U.S. Navy (well, technically begun as the Continental Navy) is this week.

Continental Navy sloop-of-war Fly (8 guns) along with Continental Navy sloop-of-war Mosquito (4 guns). Both ships were mentioned as being on station in Delaware Bay watching six British warships in a letter dated 30 December 1776.
