West coast operations occupied the remainder of the year, while the first half of 1920 was spent in overhaul at Puget Sound.

By 23 September the atoll had been occupied and Rathburne moved south, to New Guinea and the Admiralties, to prepare for the invasion of Leyte.

On 11 January, she got underway for Leyte, but 14 days later headed back to Luzon to provide support during the push against Manila.

UDT 10, disembarked on 29 January, reported no opposition at San Narciso, but Rathburne remained in the area until after the landings.
