Oboe Landings: 1945

In mid-1945, the Australian 7th and 9th Divisions conducted three amphibious operations – code-named Oboe – on Borneo. The Allies enjoyed command of the sea and the air, and used both to isolate and pummel the Japanese defenders.

The Borneo landings – well planned, resourced and executed – are rightly considered the acme of amphibious operations, yet their strategic and operational utility has been questioned. By 1945, US forces had retaken the Philippines and were pressing towards Japan, while Australia was tasked with the conduct of these landings. Japan had yet to surrender and there was still fighting ahead, but Japan’s defeat was certain.

Oboe Landings: 1945 describes the planning and execution of the three landings: Oboe 1 on Tarakan, Oboe 6 on Brunei and Oboe 2 on Balikpapan. Although the political and strategic context is covered, this book focuses on operations and tactics, and demonstrates how the Oboe operations benefited from amphibious expertise developed in the Pacific theatre. As amphibious operations bring together land, naval and air assets to act in concert, amphibious expertise is joint in nature. This expertise comprised the development and use of specialist equipment, creation of fit-for-purpose command and control systems, joint and Allied interoperability and an overall amphibious mindset.

Dayton McCarthy uses official histories and war diaries to explain these complex operations, focusing on the often-overlooked aspects such as the logistics, staff work and planning and the role of air and naval forces. As Australia again re-examines the role of amphibious operations in its near region, the subject matter of this book is timely.
