Passage: Oklahoma left for Portland on 26 November, joined there by Arizona on 30 November,  Nevada on 4 December, and Battleship Division Nine's ships shortly after. The ships were assigned as a convoy escort for the ocean liner SS George Washington, carrying President Woodrow Wilson, and arrived with that ship in France several days later. She departed December 14, for New York City, and then spent early 1919 conducting winter battle drills off the coast of Cuba. On 15 June 1919, she returned to Brest, escorting Wilson on a second trip, and returned to New York, on 8 July. A part of the Atlantic Fleet for the next two years, Oklahoma was overhauled and her crew trained. The secondary battery was reduced from 20 to 12 5-inch/51 caliber guns in 1918. Early in 1921, she voyaged to South America's West Coast for combined exercises with the Pacific Fleet, and returned later that year for the Peruvian Centennial.

Question: What month was a return to New York made?
