Wednesday, June 20, 1945 www.onwar.com

In the Ryukyu Islands... On Okinawa, Japanese resistance along the center of the line, held by the US 24th Corps, continues to be strong. The US 32nd Infantry Regiment (US 7th Division) reaches Height 89, near Mabuni, where the Japanese headquarters have been identified. On the flanks, the American Marines on the right and the infantry on the left advance virtually unopposed, capturing over 1000 Japanese and reaching the southern coast of the island at several points. The scale of surrenders is unprecedented for the forces of the Imperial Army.

In the Philippines... On Luzon, Filipino guerrillas advance up the Cagayan valley from Aparri and liberate the town of Tuguegarao. The American regimental task force enters Aparri while elements of the US 37th Division advances 2.5 miles north of Ilagan. Meanwhile, the US 8th Army headquarters announces that operations to recapture the islands of Panay, Negros, Cebu, Bohol and Palawan, as well as the western part of Mindanao, are completed.

Over Wake Island... US Task Group 12.4 (Admiral Jennings) with the carriers Lexington, Hancock and Cowpens conduct air raids on Japanese positions. The carriers are en route to join US Task Force 38.

In China... The Allies agree on a plan to capture Fort Bayard (now Zhanijang), on the South China Sea, by August 1st. The area is intended to serve as a base for operations against Japanese held Hong Kong and Canton.

In the Greater Sunda Islands... On Borneo, Australian forces land at Lutong in eastern Sarawak.

In London... The Polish government in exile denies the right of the Soviets to try the Polish ministers who had flown to Moscow and were arrested.
