On December 9, the "Wyalusing" and other Union Navy ships attempted to capture the "Rainbow Bluff" but were forced to withdraw when several Union ships were damaged by Confederate torpedoes en route. The "Wyalusing" then resumed blockade and amphibious duties around Plymouth late that month. On January 9, 1865, the "Wyalusing's" crew captured the schooner "Triumph" at the mouth of the Perquimans River, helped remove torpedoes from the sound and its related rivers and streams, and captured a Confederate schooner, remaining near Albemarle Sound and Cape Hatteras until mid-May 1865 when they sailed for home. Arriving in New York City on May 21, they were then honorably discharged.
