after repairs at philadelphia, "wasp" returned to duty in the delaware river and bay. on 5 may, two british men-of-war, the 44-gun and the 28-gun , entered the bay with several prizes. in the face of these two formidable enemies, "wasp" retreated into christiana creek, but came out again on the 8th to join a force of galleys in attacking "roebuck" after she had run aground. during the ensuing engagement, the continental schooner captured the british brig "betsey" and took her into philadelphia where the british officers were placed in jail.
