A small tribe of Lutuanian Indians from northeastern California, who, following a long series of wars with the whites, was placed part upon the Klamath Reservation, Oreg., and part upon the Quapaw in Oklahoma.
The second Modoc (WPG-46) was launched as a Coast Guard cutter by Union Construction Co., Oakland, Calif., 1 October 1922 ; sponsored by Miss Jean Lemard ; and commissioned 14 January 1923.
Home ported at Wilmington, N.C., Modoc began Atlantic ice patrol service with the International Ice Patrol in 1923. For much of the next 18 years, she and another cutter alternated on 15-day patrols off the Grand Banks, using Halifax, Nova Scotia, and Boston as their bases.
Transferred to the Navy by Executive Order No. 8029 of 1 November 1941, Modoc joined the Greenland Patrol, whose orders were to do "a little of everything." This duty involved keeping convoy routes open, breaking and finding leads in ice for the Greenland convoys, escorting the convoys and rescuing survivors from torpedoed ships, constructing and maintaining aids to navigation, and reporting weather conditions. Ships of the patrol were also expected to discover and destroy enemy weather and radio stations in Greenland, continue hydrographic surveys, maintain communications, deliver supplies, and conduct search and rescue operations. All of these duties, the Coast Guard performed with exemplary fortitude and faithfulness throughout the war.
In both World Wars, when submarines were more of a menace than icebergs, the International Ice Patrol was suspended so that the cutters could perform more important escort duty. During these years there was but one major collision ; British ship Svend Foyne struck a berg 21 January 1943. Before she sank Modoc rescued 128 survivors.
Modoc, in company with cutters Northland and General Greene rescuing survivors from torpedoed convoy ships, has also witnessed a large part of German ship Bismarck's death battle 23 to 27 May 1941. Close to midnight 24 May Modoc found herself in the midst of an attack in which eight planes and three warships were involved. Antiaircraft fire from Bismarck whizzed dangerously close to the cutter's port bow. HMS Norfolk was about to take the cutter under fire until HMS Prince of Wales identified her as U.S. Coast Guard. The cutters were undamaged, although they were near the fighting and at times only 6 miles from Bismarck. The widespread movements of the combatants, 19 plus destroyers and smaller ships, had distributed danger over a wide area. Aircraft had played a continuous part in coordinating activities, thus adding to the danger of accidents to innocent bystanders, a role the cutters had to play prior to Pearl Harbor.
On the Greenland Ice Patrol plodded many of the Coast Guard's older, smaller, and slower ships. They endured much discomfort amid the dangers of fog, storms, ice, and German raiders, but their work was vital to victory in the Atlantic.
Modoc returned to the Treasury Department in accordance with Executive Order No. 9666 of 28 December 1945, and served as a patrol cutter until decommissioning in 1947. Sold to Manuel Velliantis in Honduras, she was converted for merchant use and renamed Amalia V. Registered in Ecuador in 1960 by Tropical Navigation Co., she was renamed Machala , and served as a merchantman until scrapped in 1964.
Modoc received one battle star for World War II service.
