Mounting Urgency: Krueger and Eisenhower prepare for war
Mounting Urgency
After a few days of inspections by General Krueger and analysis of plans by General Eisenhower, a flurry of orders begins flowing out of the Manila Hotel where both Admiral Hart and General Krueger (for a brief time) live. Both commanders agree to move their headquarters initially to Fort McKinley, adjacent to Nichols Field and within a few miles of Cavite after Eisenhower convinces Generals Krueger and Frank that it would be highly desirable for Admiral Hart to have use of a DC3 or Beechcraft at his beck and call, and that such a gift would improve cooperation. For the first time in the history of the Department the two services have staff working at the same location.

Eisenhower persuades Krueger, who needs little such, that the best thing to do is to get the USAFE out in the field for some field training, particularly the I Corps. Live fire training is particularly needed for support weapons and artillery, and on November 11th, for over a week, the units of I Corps do just that, while it is the first such ever for the Philippine Army Divisions. Many problems are found, but some of the more pressing are that nearly 80% of the mortar ammunition for the 3 inch mortars that provide the bulk of company and battalion firepower for the Philippine Army are duds. An urgent message is sent to the United States for immediate resupply, while every available ordinance sergeant in the Far East is put to work looking for solutions that can be done locally.

Eisenhower meanwhile discovers that little has been done to prepare the movement of supplies to Bataan in the event that War Plan 3 (the back up plan) gets put into effect, and he bargains with the Navy, Army Air Force and just flat out strips I Corps of their medium and heavy trucks, and organizes them into truck companies with Philippine Army drivers, along with Military Police Companies. These companies remain assigned to their units but on the issue of a code word, they are assigned to the Quartermasters who will use them to move supplies from base areas on the Luzon plain as well as government warehouses such as the NARIC warehouse as well as corporate warehouses along the south harbor of Manila well be seized on issue of that same code word. Supplies will then be moved to Bataan by barge, craft and ship. Eisenhower also orders General Moore to immediately fill his warehouses for his harbor forts and ensure that stocks for 12 months are on hand at all times.

Another maneuver is set for January 1942, where the I Corps will prepare in cooperation with the newly arrived 27th Bombardment Group (and their A24 dive bombers) as well as naval forces to practice a counterattack on a potential Japanese landing at Lingayen Gulf. However, the first war warning on November 30 makes it clear that time is increasingly running out. Krueger orders his troops to hurry their maintenance stand downs and get everything back up and running as quickly as possible. He also finalizes his command structure. He remains as theater commander, but he places Eisenhower as commander of all forces in Luzon. Under him is General Wainwright, commanding the US I Corps, General Ord, commanding the II Corps, and General King, commanding the III Corps, plus General Moore commanding the Harbor Defenses of Manila Bay, Subic Bay, Lingayan Gulf, Lamon Bay and Balayan Bay. General Frank commands US Army Air Forces Far East (USAAFFE) but his responsibilities have been expanded to include liaison and cooperation with the Australians, Dutch and British. After an inspection of the American Volunteer Group, Generals Frank and Eisenhower send a cable to Washington urging that Claire Chennault be given a reserve commission of Brigadier General and Eisenhower, Frank and Hart quietly work out a plan to make use of that organization in case war comes before it leaves.

In late November and early December, the 4th Marine Regiment arrives from Shanghai, and Admiral Hart generously places it under Army tactical command. Krueger is pleased to get another regiment of regulars, and he promptly allocates it as the reserve for III Corps.

As of December 8, 1941, all Filipino troops have at least 9 months service, with most having more than that, and are familiar with their weapons and chain of command. While still limited in their tactical training, they are not substantially less trained than the US National Guard troops that have sent to join them.
