Named c1859 by Captain Richards, after Rear Admiral Sir Robert Lambert Baynes ( -1869), commander in chief of the Pacific Station 1857-1860, flagship Ganges, 84 guns; KCB 1860; Vice Admiral 1861; Admiral 1865. "....It was through his wise forbearance that no collision took place on San Juan Island between the British and American forces... summer of 1859. Neither the provocation of his enemies nor the rashness of his friends would allow him to hurry into ill-considered action, though he had an ample force to have prevented them landing or to effect their capture afterwards...."
