The expedition assigned to Captain Barry which he came near being deprived of by Congress was a cruise in the Delaware River. The Marine Committee, not being directed not to employ Barry, on January 29, 1778, directed him to fit out the pinnace and barges belonging to the frigates for "a cruise in said river under your command." He was empowered to "receive stores and employ such Continental Navy officers and call the number of men necessary for officering, manning, victualing and equipping the boats." He was directed to have frequent occasion to land on each side of the Delaware and to restrain his men from plundering or insulting the inhabitants. The Navy Board was directed to supply "everything necessary for your little fleet" and money to procure supplies. He was directed to inform General Washington of such stores as he might capture which are necessary for the use of the army. He was to sink or destroy the vessels which he could not remove to safety. His "despatch, activity, prudence and valor," were relied on to bring success. If Barry's project to destroy British shipping by explosive machines did not succeed, another form of endeavor dependent more upon skill and bravery would accomplish results as satisfactory as had been hoped for by the floating "score of kegs or more that came floating down the tide." The Supreme Executive Committee of Pennsylvania, then at Lancaster, on February 7, 1778, notified the Navy Board, then at Burlington, New Jersey, that "a spirit of enterprise to annoy the enemy in the river below Philadelphia had discovered itself in Captain Barry and other officers of the Continental Navy, which promised considerable advantage to the adventurous as well as to the public."
