The Return of the King, LoTR Appendix B, The Tale of Years: The Third Age
'Thorongil often counselled Ecthelion that the strength of the rebels in Umbar was a great peril to Gondor, and a threat to the fiefs of the south that would prove deadly, if Sauron moved to open war. At last he got leave of the Steward and gathered a small fleet, and he came to Umbar unlooked-for by night, and there burned a great part of the ships of the Corsairs. He himself overthrew the Captain of the Haven in battle upon the quays, and then he withdrew his fleet with small loss.'

[Note: The year is known because Appendix A goes on to say that Ecthelion died four years later, which is known to be 2984.]
