Major General John C. Fremont made St. Louis his headquarters when President Lincoln gave him command of the Union's Department of the West. Missouri was a divided state. The people of Missouri had been deeply involved in the "Bleeding Kansas" conflict well before the US Civil War. Now Missouri, a slave state, was burdened with sectional conflicts. Fremont had to control a state that had pro and anti-slavery militias. Armed conflict between pro-Confederate guerrillas and Union troops made things extremely difficult for Fremont.
When Major General John C. Fremont issued his proclamation freeing slaves in Missouri, he was out of step with President Lincoln. Lincoln made it clear that Fremont was making political policies that he did not have. The dispute became ugly and Lincoln replaced Fremont with Major General David Hunter.
In the early part of the US Civil War, President Lincoln was upset with the political operations of General Fremont in Missouri. At one point Fremont, declared that Missouri slaves were now "free". This was beyond the jurisdiction of any Union general. Halleck, an experienced West Point (USMA ) graduate was sent to St. Louis as Fremont's replacement.
Major General Henry W. Halleck was President Lincoln's replacement for the over-stepping General Fremont in Missouri. In a number of letters to Washington DC, he expressed grave concern about the Border-slave state. Confederate General Sterling Price in northwestern Arkansas was trying to convince Jefferson Davis that with a sizable army he, with the help of Southern sympathizing Missouri militias could take and hold three quarters of Missouri. Halleck, with the aid of generals Pope and Curtis were gathering pro-Union militias to thwart any Confederate threat to the key state of Missouri.
General in Chief Winfield Scott and President Lincoln wanted General Fremont to raise an army and prepare them for military action against the Southern Rebels. His objective was to move down the Mississippi and focus on capturing Memphis, Tennessee.
President Lincoln had to make many political appointments during the US Civil War. This included military appointments which included John C. Fremont to head the Western Department that included Missouri. It's true that Fremont had a role in securing California during the Mexican American War. The political realities were Fremont's leadership in the abolitionist wing of the Republican Party. Also there was pressure from German Americans and the politically powerful Blair family. These factors counted allot, plus Fremont was eager to take the job as a major general.
What cannot ever be underestimated was the struggles of US President Lincoln during the four years of the US Civil War. That in itself was a burden that perhaps to few people of his time fully understood.Two Union generals, one a good friend of Lincoln's had to be either replaced and reprimanded or simply reprimanded were generals John Fremont and Major General David Hunter. In the Western Department of Missouri, abolitionist General John Fremont, also a Radical Republican candidate for the US presidency in 1856, declared, on his own, that slaves owned by contentious Missouri slave owners were to be set free by order of General Fremont. Such a crucial subject was not to be decided by an independent minded general. Lincoln reversed that decision and replaced Fremont with General Hunter, a man that Lincoln allowed Fremont to nominate himself. Hunter was well aware of why Fremont was replaced. Despite that, Hunter fell victim to his own abolitionist goals later in the war in the South Carolina sea islands. There General Hunter declared the freedom of all slaves. Most likely to Lincoln's astonishment and dismay, that decision was reversed by Lincoln. As an aside, the burdens of President Lincoln were heavy, as mentioned earlier on. Now despite what General Hunter knew, he did exactly what caused the dismissal of General Fremont. To both these generals and Radical Republicans, President Lincoln had the onerous duty to keep the war under civilian control, where the Constitution wanted it. Not by radical generals.
John C. Fremont. Fremont had been the first Republican presidential candidate in 1856. He had gained fame as "The Pathfinder" from a book he published detailing his explorations of the west. He was married to Jessie Benton, the daughter of powerful Missouri Senator Thomas Hart Benton. For this reason he had been given command in Missouri, where he issued his proclamation without consultation with the administration in Washington. This was at a time when Lincoln was trying to woo the undecided in the border states, and Lincoln ordered Fremont's proclamation rescinded. Despite an emotional personal visit from Jessie Benton Fremont, Lincoln held firm and Fremont resigned in a huff, no doubt to the considerable relief of Lincoln.
In 1863, General in Chief Henry Halleck had appointed Major General John Scofield as the commanding officer of the Department of Missouri. Scofield was a New Yorker and a graduate of West Point. Missouri was an important border state and a slave state. It was vital that Missouri and other border states remained in the Union.
The Battle of Belmont took place on November 7, 1861 in Belmont, Missouri. General Fremont sent Brigadier General US Grant and 3,000 men downriver from Cairo, Illinois. His troops had an escort of two gunboats. There Grant defeated the Confederates for his first victory in the war. Not long after, Confederate Major General Leonidas Polk sent new troops to Belmont forcing Grant to retreat. Union casualties were 607 and Confederate losses numbered 641.
