Civil War and Governorship
With secession and the Civil War, Colonel Baker retired to Franklin, Louisiana, in 1861. As a Conservative Democrat who opposed secession, he chose to cooperate with the Union Army of Occupation.[4] On January 8, 1868, Baker took the Oath of Loyalty to the Union. He was Appointed Military Governor by General Winfield Scott Hancock upon the resignation of Benjamin Flanders. As Governor, Baker supported the lenient reconstruction plan of President Andrew Johnson. His administration had little influence on the course of the Louisiana government, as its orders were liable to be countermanded by the military due to the reconstruction acts. Baker removed 9 New Orleans City Councilmen which resulted in President Ulysses S. Grant's reversal of this order. For this, Governor Baker resigned and in a special election Republican Henry C. Warmoth was elected Governor.[5]
