Wherein either Hooker exaggerates or global warming is real
........................................................................................................................................
The cold weather of December had brought a warming, rather than a cooling of tensions on the Lower Potomac. From the headquarters of the Department of Northern Virginia in Centreville, General Joseph E. Johnston was preparing his Southern army for a battle that he expected, even this far into the winter. While winter campaigning was something that no army enjoyed, it certainly wasn't unusual. Writing to his subordinate commanders about the situation, Johnston would have been well aware that Union forces were on the offensive in the Western Virginia mountains and that Brig. Gen. Thomas "Stonewall" Jackson was playing a cat and mouse game with two Union forces in what is today the West Virginia panhandle.
On December 5, Johnston had written to Brig. Gen. William H.C. Whiting, commanding his right flank at Dumfries about the eventuality of an attack by the Union army and his plans for a Confederate response.
My Dear General... I want to know precisely what roads are open and which closed. Please inform me The enemy's movements might be such as to tempt me to go in your direction first. It is necessary to be prepared to do so at all events... Should we go against your enemy it ought to be in two columns on those two routes.And, referring to the way he had tricked Union Maj. Gen. Robert Patterson before Manassas into thinking his army was at Winchester when it was in fact on the way to turn the battle's tide, he added a line that would have brought a shout of triumph to Professor Thaddeus Lowe: "The infernal balloon may interfere with such success as we had with Patterson."
Meanwhile, Johnston was also in a letter battle with Richmond over orders issued by Secretary of War Judah P. Benjamin that he immediately create two brigades of only Mississippi troops, which Johnston scornfully refused to do in several hundred words, especially because two of his Mississippi regiments were with Whiting.
The forces as now arranged are perfectly familiar with their respective positions, officers and men have become accustomed to each other, are acquainted with the nature of the ground they occupy, &c. The execution of Orders No 252 would work a complete revolution in the organization of the army, and necessitate a change of position of all the regiments from Leesburg to Dumfries, and from this position to Dumfries and Leesburg. Should the enemy attack us whilst these changes of station are in process, an event by no means improbable, it would be almost impossible to avert disaster to our arms.Benjamin, naturally, wrote back expressing President Jefferson Davis' "desire" that Johnston should simply send the 13th, 17th, and 18th Mississippi regiments from Leesburg (where they had been crucial at Ball's Bluff) to Whiting as reinforcements, "to whose brigade they belong". Johnston could then move any other brigade to take their place at Leesburg, never mind that the last major troop movement at Leesburg had prompted a battle.
