Quezon on recommendations by MacArthur, to become the chief of police of a new capital being planned, now named Quezon City, but he declined the offer.

In June 1941, he was appointed Chief of Staff to General Walter Krueger, Commander of the 3rd Army, at Fort Sam Houston in San Antonio, Texas. After successfully participating in the Louisiana Maneuvers, he was promoted to brigadier general on October 3, 1941.

Document 10: Dwight D. Eisenhower: Edgar took the first turn at school, and Dwight was employed as a night supervisor at the Belle Springs Creamery. Edgar asked for a second year, Dwight consented and worked for a second year. At that time, a friend "Swede" Hazlet was applying to the Naval Academy and urged Dwight to apply to the school, since no tuition was required. Eisenhower requested consideration for either Annapolis or West Point with his U.S. Senator, Joseph L. Bristow.

He commanded a unit that trained tank crews at Camp Colt – his first command – at the site of "Pickett's Charge" on the Gettysburg, Pennsylvania Civil War battleground. Though Eisenhower and his tank crews never saw combat, he displayed excellent organizational skills, as well as an ability to accurately assess junior officers' strengths and make optimal placements of personnel.

Patton, Sereno E. Brett, and other senior tank leaders. Their leading-edge ideas of speed-oriented offensive tank warfare were strongly discouraged by superiors, who considered the new approach too radical and preferred to continue using tanks in a strictly supportive role for the infantry. Eisenhower was even threatened with court martial for continued publication of these proposed methods of tank deployment, and he relented.

In retirement, the former president did not completely retreat from political life; he spoke at the 1964 Republican National Convention and appeared with Barry Goldwater in a Republican campaign commercial from Gettysburg.
