Served on board the USS Fort Hindman during the engagement near Harrisonburg, La., 2 March 1864. Following a shellburst which mortally wounded the first sponger, who dropped the sponge out of the forecastle port, Molloy jumped out of the port to the forecastle, recovered the sponge and sponged and loaded the gun for the remainder of the action from his exposed position, despite the extreme danger to his person from the raking fire of enemy musketry.
