ルンガ沖夜戦
On 30 November, "Lamson" joined Rear Admiral Wright’s Task Force 67 during the Battle of Tassafaronga. One Japanese destroyer was sunk and one damaged while the American force lost one cruiser and three damaged. "Lamson" returned to operate in the South Pacific for the next 8 months, screening convoys en route to Guadalcanal. Constantly at sea on patrol and ASW screen, the destroyer assisted other units as they paved the way for the Allied advance across the Pacific.
