The final version of the outline plan originally called Operation Princeton, it outlined plans to recapture the Visayas and Mindanao in the Philippines, Borneo and the Dutch East Indies.
The operation was planned by the South-West pacific Area command under General Douglas MacArthur, and was a joint US and Australian effort.
The US 8th Army under Lieutenant General Robert L. Eichelberger was allocated the Visayas part of the operation, and the I Australian Corps under Lieutenant General Sir Leslie Morshead was allocated the Borneo part.
Nonetheless, on February 6, 1944, General MacArthur ordered General Eichelberger to mop up the Japanese forces in the Philippines with his 8th Army, supported by Vice Admiral Thomas C. Kinkaid's 7th Fleet.
Once Borneo had been liberated, I Australian Corps was to form part of the invasion of Java.
