It seems the Union was targeting the banks in their sweeps to disperse the rebels. This may have motivated the confederate guerillas to begin molesting the train system, first firing into one, and finally the tragedy that unfolds at Platte River on Sept. 3, 1861.
Fremont, reporting on the action at Springfield when Brig. Gen. Lyons was killed, states Brig. Gen. Sigel on the 11th of August while continuing his retreat through Rolla brought off $250,000 dollars of specie from the Springfield Bank. [page 54]
On the 16th of August, a force of Eighth Regiment Missouri Volunteers under Major John MacDonald, acting upon orders from Cape Girardeau, captured the town Saint Genevieve, Missouri. McDonald in his report [page 132] states; "I then caused the branch of the Merchant's Bank of Saint Louis to be opened, and I took from it a box said to contain $28,633.30 in coin and $29,680 in currency, total $58,313.30, and brought the same on board the steamer [Hannibal City] which I have the honor to turn over to you in person. Stockholders and directors expressed great gratification at my taking the money…."
On the 16th of August a band of guerillas fired into the train near Palmyra, Missouri, killing one man. General Hurlbut on the 19th issued a proclamation that unless these guerillas were turned within 6 days, that he would levy $10,000 dollars from Marion County and $5,000 from the City of Palmyra. [page 135].
On September 3rd, it was reported by confederate General Jeff. Thompson [page 155]; "The Federal Troops took $700,000 from the bank at Cape Girardeau yesterday."
Colonel Nelson Williams of the Third Iowa Infantry reports he arrived in Paris, Missouri early on the morning of the 2nd, and immediately proceeded to the bank. "We called the directors together. They informed us that the cashier had taken the money to a safe place, and that they did not know where he or the money was." [page 158].
How possible was it that the rebels were hoping to make use of the rails for themselves. The Union was using the railroad branches for resupply and movement of troops; relocation and retreat, too. Was there any chance Governor Jackson's men could have commandeered the system?
