He was given command of the fifth-rate HMS Fox in 1852, of the frigate HMS Eurydice in 1855 and of the frigate HMS Euryalus in 1858: he led the latter ship as an element of the Channel Squadron and then of the Mediterranean Squadron. Tarleton served as Junior Naval Lord from 1871 and then as Second Naval Lord from 1872 to 1874. He was promoted to Vice Admiral in 1875 and retired in 1879.
