On October 21, 1861, a minor battle occurred near Fredericktown, in Madison County, southeast Missouri. Union losses were 6 killed, 60 wounded, per Colonel Plummer’s report. A rebel (MSG) report indicated 20 killed, 27 wounded. However, Colonel Plummer reported Union troops buried 158 enemy, found on the battlefield.
The rebel (MSG) commander of the First Military Region of the former Military State Guard was self-proclaimed Brigadier General M. Jeff Thompson. In 1861, that was a lightly populated swampy area of southwest Missouri.
Thompson’s activities revolved around giving the forces of U.S. Grant and the people of Missouri the impression his small force was an army preparing to move north as part of a Confederate operation to capture St. Louis.
[His area of operations was] a miry, swampy region, utterly impracticable for baggage wagons. The country is now almost destitute of forage and provisions, the inhabitants living on cornbread and pork exclusively. During the remainder of this year, if Thompson should return, he can accomplish nothing but to devour what little remains. From all accounts, he is disgusted and dispirited, and his forces kept together only by fear of being arrested by us. —Col. Carlin, 38th ILL. Inf. (FLP: Vol 8-Nov#19.2)
A master of self-promotion and deception, Thompson was quick to issue proclamations and write bellicose letters that were picked up by the national press, as he worked to deceive U.S. forces, concerning the size and location of his force; consequently, he initiated few engagements. In a letter to the region’s Confederate commander Thompson wrote:
My rapid and unexpected movements have fully convinced them that my force is very large, and I have also exercised my talents upon them with fictitious orders and reports…
Thompson’s actions, described above, which earned him the moniker of Swamp Fox, unwittingly helped Grant train and motivate his forces under what were low intensity combat conditions, as his regiments scurried around searching for Thompson’s shadow army. Prior to the “Battle” of Fredericktown, Gen. Grant wrote the following to Col. Plummer:
I am satisfied that you can have no force to contend against but Thompson and Lowe’s. I feel but little confidence in your ever seeing them, but information just received from St. Louis reports Thompson as fortifying Fredericktown. You will, therefor, march upon that place, unless you should receive such information on your march as to indicate a different locality for the ubiquitous individual.
Even though Grant did not expect to find Thompson, he dispatched the large force listed above to converge on Fredericktown (good training for recently organized units). Upon arrival, that force found Thompson had already departed, as a messenger carrying the plans for the Union movements was captured when he passed through Fredericktown. However, rather than fleeing the area, Thompson established what he intended to be a hit and run ambush position south of town, “hoping to waylay enemy details as then came to get him in Fredericktown.” When Thompson sprung his ambush, he gave Union forces an opportunity to execute the battle drills they had been practicing for months. Fortunately for Thompson, the Union Calvary only pursued him for 10 miles, allowing him to escape.
As General Grant realized the battle was a rather minor affair, he reportedly stated the following.
The importance of the success cannot be measured by any ordinary standards; it gave new life to tens of thousands of our discouraged soldiers. It crushed out the rebellion in Southeast Missouri.
The large force management skills gained by Grant in southeast Missouri in 1861, as he searched for Thompson’s fake army, were put to good use after he crossed the Mississippi and started his trip toward Appomattox Court House. Prior to 1861, Grant had never commanded more than the 100 men in his own infantry company, and that was in a peacetime army.
 Thompson was unhappy because the Confederate Army would not support or even work with him.
