Operation Montclair

Operation Montclair was a military operation during the Second World War. 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 McArthur, 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.

US plans originally called for the elimination of the Japanese garrisons in the unliberated parts of the Philippine islands to be performed by Filipini guerilla's and the reformed Filipini army. Nonetheless, on February 6, 1944 General McArthur 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. this culminated in a series of operations called Operation Victor I through V:

• Battle of the Visayas (Victor I, II, II)
• Battle of Mindanao (Victor IV, V)

At the same time, I Australian Corps was order to take Borneo to supply the US forces for the invasion of Japan with oil. Once Borneo had been liberated, I Australian Corps was to form part of the invasion of Java. For more details, see Borneo campaign (1945)
