1941 Reinforcement
Expansion of the Philippine Army
An infusion of money allows the Philippine Army to call up over 30,000 conscripts in January 1941, enough to bring all 14 brigades of the Philippine Army up to strength as well as replace those who volunteer for service in the Philippine Scouts. The work over the last years to expand training camps and make them habitable pays off this year as well as the efforts to obtain sufficient weapons for the troops. The Army is able to raise an additional 2 MP brigades, and with the arrival of heavier guns fro the US Army and Philippine Scouts, as well as stripping 120 75 mm guns from formations elsewhere (plus those released from the Scouts) the Philippine Army is able to form 10 light artillery battalions of 12 guns each. With the addition of artillery, the 20 MP regiments are reorganized into 6 light infantry divisions (3 regiments infantry, 1 battalion light artillery, 1 engineer/pioneer battalion each) with 1 division each (31st and 41st) at Mindanao and Cebu, and the remaining 4 (11th, 21st, 51st, and 61st) organized into 2 small corps. Each corps is also assigned an engineer brigade (1st and 2nd), while the remaining 2 MP regiments are assigned to Manila and far northern Luzon, while 1 engineer brigade (3rd) is assigned to the Del Monte area and another continues work on improving airfields in Bataan (along with an American aviation engineer battalion) as well as providing engineer companies to continue work improving airfields in Luzon.
Another division, the 1st Division, is raised from cadres supplied by the Philippine Army and Philippine Scouts. Sufficient artillery is found to raise a full regiment of guns (36 75 mm guns) for this division, and sufficient trucks for them as well plus move one of its three regiments at a time. More trucks are on order but they will not reach the Philippines until sometime in 1942. It is assigned to the Mobile Force providing that formation with a third division, although one less well equipped or trained than the other two.
What is missing though are sufficient machine guns and any anti tank artillery for the other 6 divisions of the Philippine Army. Lacking any other choices, the 2.95 inch mountain gun, dating back to the last century, are given trucks and although they have wooden wheels they can be broken down they are mobile enough to move to a vital area although once placed will likely not be able to withdraw. With this expedient a total of 48 anti tank guns are put into service, enough that each of the 4 divisions in Luzon is able to field an anti tank battalion of 12 guns each, which are also were the bulk of the few heavy machine guns that the Philippine Army has available are concentrated (aside from those assigned to air defense). However each company has only 3 light machine guns, and each platoon only 3 BARs, although a few old Lewis guns are found to put into service by companies lucky enough to find them.
However the Coast Artillery finally gets weapons that it needs. A sufficient number of 8 inch guns are found for use by the 1st and 2nd Coast Artillery, Philippine Army, giving each 3 firing batteries and spare tubes. The other 6 batteries in each regiment are given World War I era 155 guns. The 1st Coast Artillery is assigned Lingayen Gulf, while the 2nd Coast Artillery is deployed so that a battalion each covers the Iba/Palauig area, Lamon Bay, and Balayan Bay. The Marines of the 1st Provisional Battalion (USMC) and elements of the US 59th Coast Artillery cover Subic Bay, while the remaining US and all of the Philippine Scout units are manning the Manila Bay fortifications.
US Army reinforcements
The most important arrivals are the 192nd and 194th tank battalions, which between them have 108 M3 Stuart tanks and 46 halftracks fitted with 75 mm guns which have an armor ordinance company as well. General Weaver is assigned command of a provisional brigade sized force called 6th Cavalry Brigade (provisional) consisting of the 1st Provisional Armored Group, the 26th Cavalry (PS) Regiment, and the newly arrived 112th Cavalry Regiment (Texas National Guard) giving him nearly 2,600 armored and cavalry troops. The remaining reinforcements are sufficient personnel to bring the US units in the islands up to strength.
Two regiments of 105 mm guns, as well an infantry regiment are en route, as well as an aviation engineer brigade and heavy equipment such as bulldozers and other earth moving equipment and vehicles are aboard the Pensacola convoy.
A new commander October 1941
In September, now past retirement age and in increasingly poor health, General Parsons is forced to ask for relief. Although General Grunnert is briefly considered for the position, in the end it is decided that as General Krueger has done very well in the recent Louisiana Maneuvers, and has the rank and experience commanding an army, he will be sent. With him is sent his Chief of Staff, Brigadier General Dwight Eisenhower. Both men get a brevet promotion with the job, Krueger to four star general and Eisenhower to Major General (although Ike gets that as a permanent rank as well).
They arrive aboard the Manila Clipper and the change of command ceremony occurs on October 21, 1941. Sent home with Parsons is General Grunnert who is being given an assignment in the US and General Wainwright is given command of the US I Corps.
