In May 1813 it was reported that within the space of two days a merchant vessel, "Pilgrim", was boarded, first by which was searching for "Syren", and then by "Syren", which was searching for "Herald". "Syren" was now commanded by Lieutenant Joseph Bainbridge. The following month "Syren" left Belize and proceeded to Cuba where after three weeks searching for a Royal Navy sloop, probably "Herald", she sailed for the coast of Florida putting in at New Orleans before departing on 9 May 1813. No prizes were taken during this voyage and the ship needed repairs.
