American-British-Dutch-Australian Command

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. It consisted of the forces of Australia, the Netherlands, United Kingdom and the United States. Led by General Sir Archibald Wavell, the command's objective 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.
