Wartime History
Starting in November 1942, Allied personnel used Oro Bay as a staging area during the campaign against the Japanese defenders at Buna, Gona and Sanananda.  By November 14, 1942 U.S. Army soldiers had consolidated into the Oro Bay area and developed it into a aging area and anchorage for Allied small ships.

During December 1942 Operation Lilliput began as convoys of small ships and barges to move supplies from Milne Bay northwest to Oro Bay. Within six months, the convoys had delivered 60,000 tons of supplies and 3,802 personnel. Corvettes provided the majority of the escorts.

US Army Base B (Oro Bay)
In early 1943, Oro Bay was further developed by the U.S. Army into a major base area. Designated "Base B" by U.S. Army Letter Base designation. Shore facilities were expanded to include Liberty Ship Wharves on the south side of Oro Bay, plus an engineering depot at the center of the bay. On the northern side was headquarters Base B, fuel jetty and bulk petroleum storage. Further inland was a hospital and radio transmitter. Later, the area was further developed, including a detention center to rehabilitating soldiers with combat neurosis.

During 1943, Oro Bay was the target of many Japanese air raids against shipping that sank several vessels. Air combat was frequent over the area as defending U.S. planes intercepted the Japanese formations.
