The 865th Bombardment Group was the second of three B-24 Liberator squadrons formed to create the 494th Bombardment Group, the last Liberator group to leave the United States during the Second World War. The three new squadrons were joined by the 867th Bombardment Squadron, which under three different designations had taken part in the anti-submarine war since early in 1942, and after spending most of 1944 in training the new group left for Angaur at the end of September 1944.
The B-24s of the 866th Bombardment Squadron were left in their natural metal finish and could be distinguished by a backslash painted in black on the tail.
The 866th operated from two main bases during its time in the Pacific - first on Angaur from late in 1944 until June 1945, and then from Okinawa to the end of the war. While based on Angaur the squadron carried out attacks on Japanese held islands in the Palau group and took part in the campaign on the Philippines. The squadron took part in the first B-24 raid on Japan from Okinawa and spent the last two months of the war attacking targets in the south of Japan as well as in China and Korea.
