Tomorrow is the 150th anniversary of the
Battle of Mill Springs during which George Thomas' Federal Army defeated the army of George Crittenden. That army was commanded in the field by Felix Zollicoffer, who was killed in the battle. That victory was soon eclipsed in the mind of the public by the victories at Forts Henry and Donnelson. However, Thomas accomplished in eastern Kentucky what Grant had done in the west, did in one day's battle, and did it with his typical efficiency.
Thomas was, in my never humble opinion, the most competent and the most modern officer on either side in the war. Being a native of Virginia, he had no political influence. That, combined with his diffidence meant that he exercised no major independent command until after the battle of Chicamauga. A simple fact can show what a difference Thomas' thoroughness and modernity made, and that was how long it took for the news to get out. After the defeat of Zollicoffer's brigade, Thomas organized his troops, and prepared to advance the next morning. The survivors of Zollicoffer's brigade began to arrive in Crittenden's camp, a fortified camp which was also the depot for all of the military, public property in eastern Kentucky. Crittenden panicked and retreated, leaving all of the public property behind, and most of it was not burned, as it ought to have been, if Crittenden had been doing his job properly. Crittenden was soon accused of drunkenness (and even treason!) and was relieved of his command. Although casualties were light, his command was broken up, and the troops were effectively out of the war for months.
News of the defeat of Crittenden in two battles on January 10th and 18th did not reach the theater commander, Albert Sidney Johnston, for two weeks. Initial reports of victory were contradicted by northern newspapers, and Johnston was not assured of the outcome until officers arrived at his headquarters to demand the court martial of Crittenden. By contrast, Thomas laid telegraph wire wherever he went, and had wagons in his train with telegraph keys and telegraphers. Lincoln was informed of the outcome of Mill Springs that same evening.
Thomas had also mapped every road in the campaign area during his advance. Another wagon in his train carried the special printing press which was needed to print maps. Later, Thomas was to encounter two topographical engineers from the Coast and Geodetic Survey, and he managed to convince one of them to take a commission as Major, and join his staff. Thomas was prepared to exploit every advantage which the Union could afford--and with Lincoln's income tax, they could afford a lot.
