THE ONLY RECORDED REVOLUTIONARY WAR BLOCKADE-RUN COVER THROUGH THE AMERICAN PRIVATEER BLOCKADE OF DELAWARE BAY.
American privateers began attacking British shipping in the Spring of 1775. As America's largest city, Philadelphia was a center of trade, so British vessels in or out of Delaware Bay offered attractive prizes. By the Summer of 1775 Royal Navy warships were patrolling the mid-Atlantic coast between Cape Henlopen and Chesapeake Bay to thwart privateer attacks.
"Fifteen large galliots carrying at their bows from 32 to 48 pounders, swivels, etc. and fifty men each, are built at Philadelphia, and are to be stationed in Delawar [sic] River about Redbank, to oppose any men of war, who may attempt to come up the river, and to defend the machines sunk in that narrow part of the river." from The Ipswich Journal, England, 23 September 1775
Delaware Bay was not under a British blockade until March 1776 when the frigate HMS Roebuck entered Delaware Bay and stood off Lewes. Despite defensive measures along the Delaware, Philadelphia was invaded and occupied in September 1777.
