The American-British-Dutch-Australian (ABDA) Command, or ABDACOM, was the short-lived supreme command for all Allied forces in South East Asia in early 1942, during the Pacific War in World War II. The command consisted of the forces of Australia, the Netherlands, United Kingdom and the United States. The main objective of the command, led by General Sir Archibald Wavell, was to maintain control of the "Malay Barrier" (or "East Indies Barrier"), a notional line running down the Malay Peninsula, through Singapore and the southernmost islands of the Dutch East Indies. ABDACOM was also known in British military circles as the "South West Pacific Command", although it should not be confused with the later South West Pacific Area command (see below). Although ABDACOM was only in existence for a few weeks and presided over one defeat after another, it did provide some useful lessons for combined Allied commands later in the war. Formation Efforts to organise the ABDA Command began soon after war between the Allies and Japan commenced, on 7 December 1941. Army Chief of Staff George C. Marshall and Secretary of War Henry L.

Despite objections from the British military establishment, the scheme was finalized at the Arcadia Conference in Washington. On December 27 Marshall and Admiral Ernest King proposed an ABDA Command led by Archibald Wavell to Charles Portal, Dudley Pound, and John Dill. The British were skeptical and believed the Pacific theatre was too geographically large to be controlled by a single commander. Winston Churchill warned Marshall about the difficulties faced by Ferdinand Foch as Supreme Allied Commander while simply trying to coordinate operations across the Western Front of World War I. Marshall rebuffed this and other historical analogies from Churchill, telling him that he "was not interested in Drake and Frobisher, but I was interested in having a united front against Japan." Churchill reluctantly telephoned his War Cabinet in London advising them to accept the arrangement despite their concerns. On December 29, Winston Churchill said that it had been agreed Wavell would be supreme commander in order to assuage British concerns. Wavell then held the position of British Commander-in-Chief, India. Churchill added: It is intended that General Wavell should have a
