Editing Fort Mills (section)

===Prelude===
From the late 1930s through the surrender in 1942 a number of batteries for [[155 mm gun M1918|{{convert|155|mm|1|abbr=on}} GPF guns]]<ref>A French design, designated Grand Puissance Filloux for its designer.</ref> were built at Fort Mills. These were mobile [[field gun]]s adopted by the Coast Artillery Corps for use in "tractor-drawn" units, such as the [[92nd Coast Artillery (United States)|92nd Coast Artillery]]. At least a few of these were delivered to the Philippines in 1921 with transfer of the [[59th Coast Artillery (United States)|59th Coast Artillery]] to the islands.<ref>[http://cdsg.org/wp-content/uploads/pdfs/FORTS/CACunits/CACreg1.pdf Gaines, William C., Coast Artillery Organizational History, 1917-1950, ''Coast Defense Journal'', vol. 23, issue 2, pp. 34-35]</ref> Nine batteries with emplacements for 22 guns were built.<ref name=CDSG1/><ref name=Ber222/> The US Army's official history states that 19 of these weapons were on Corregidor during the final battle in 1942. Most of these batteries simply had "[[Panama mount]]s", circular concrete platforms to stabilize the gun on its mobile carriage. One battery was exceptional, Battery Monja in the southwest part of Corregidor, with two emplacements. One or both of these were [[casemate]]d by being built into a rock face; this proved to be crucial to the battery remaining in action during the siege. By December 1941 there were seven [[antiaircraft]] batteries totaling 28 [[3-inch Gun M1918|3-inch guns]] on Corregidor (including one nearby on Bataan), some manned by the [[60th Coast Artillery (United States)|60th Coast Artillery]] (AA) and some manned by batteries of the harbor defense regiments.<ref>Morton, p. 474</ref><ref>[http://corregidor.org/chs_battery1/ordnance.htm Table of Armaments & Coast Artillery Assignments at corregidor.org]</ref>

On 26 July 1941 Lieutenant General<ref>Major General when recalled, promoted two days later.</ref> [[Douglas MacArthur]] was recalled to active duty and made the commander of [[U.S. Army Forces in the Far East]] (USAFFE), which included the [[Philippine Scouts]] and the [[Philippine Commonwealth Army]]. MacArthur had been an [[Office of the Military Advisor to the Commonwealth Government of the Philippines|official U.S. advisor to the Philippine forces]] as a Philippine Field Marshal from 1935 to 1937, and had continued this function as a civilian since his retirement from the U.S. Army at the end of that period.<ref>Morton, p. 19</ref>
