War Plans and Seacoast Defenses[edit]

The office drew up defense plans for the islands of Luzon, Cebu, Negros, Panay, Leyte, Mindanao, Bohol, Mindoro, and many of the smaller islands. The plans included the establishment of seacoast defenses along the seven straits which give access to the inland waters of the Philippines.[1]


These plans did not involve the use of US forces, but were intended for use by district military commanders of the Philippine Army which was to be created under the National Defense Act.[1]


The seacoast defenses, mentioned above, were to consist, naturally, of heavy coastal guns. These defenses were scheduled to be completed in April 1942. The War Department, at some time or other, had sent twenty-four 155 mm guns, without fire control equipment. Later, while assigned to USAFFE, MacArthur asked for four 12 inch, four 8 inch, and 22 additional 155 mm guns, as well as 30 searchlights. This request was received in December, too late to be acted upon before Japanese offensive actions in 1941.[1]

Staff Changes[edit]

Upon the accidental death of Lieutenant Colonel Ord, in January 1938, Major Sutherland was brought in as his replacement. Lieutenant Colonel Eisenhower left in December 1939 and was replaced by Lieutenant Colonel Marshall. In October 1937, Captain Casey joined the group as an engineering advisor, and later Major Marquat was appointed as an antiaircraft advisor. These men would stay with MacArthur throughout the war.[1]

MacArthur's Point Of View[edit]

MacArthur argues, "A small fleet will have distinct effect in compelling any hostile force to approach cautiously. The only naval task is that of inshore defense. This will be provided by flotillas of fast torpedo boats, supported by an air force."[1]


MacArthur adds, "These islands have enormous defensive advantages. Luzon has only 2 areas where a hostile army could land. Each of these positions is broken by strong defensive positions.[1]


MacArthur continues, "When developed the Philippine Army will be strong enough to oppose any conceivable expeditionary force. By 1946, the Islands will be in a favorable posture of defensive security."[1]
