Johnston wrote to Bragg on the 12th that no particular plan of campaign had been communicated to him. [Footnote: _Id_., p. 613.] He does not appear to have telegraphed a brief inquiry on this subject, but wrote at some length in regard to his requirements before he could be in condition to take the field. He referred to his first opinion in favor of a defensive campaign as unchanged. The ordinary course of mail seems to have required about a week for a letter to reach Richmond. It happened that on the same day Bragg at Richmond was writing to Johnston outlining the plan of campaign mentioned above, adding that it was intended to throw a heavy column of cavalry into West Tennessee as a diversion, and that if by rapid movement Johnston could capture Nashville, Grant would be in a precarious position. The President, on assurance of the immediate execution of the plan, would order to him 5000 men from General Polk, 10,000 from Beauregard, and Longstreet's command estimated at 16,000, but which was really nearer 20,000. Putting these reinforcements and Johnston's own army at lowest figures, his column would amount to 75,000 men. [Footnote: Official Records, vol. xxxii. pt. iii. p. 614.] After posting his letter of the 12th, Johnston went on an inspection tour to Atlanta, and there on the 13th he received and answered Longstreet's letter of the 5th. He pronounced impracticable the plan submitted to them, and reiterated his fixed opinion that it was best to wait for Grant's advance. In any event, he thought a forward movement should "wait for the grass of May." [Footnote: _Id_., p. 618.] He argued that it was better to let the enemy's forces advance, and fight them far from their base and near his own. Bragg, on the other hand, had urged the recovery of the populous region of Middle Tennessee as necessary both for obtaining army subsistence and forage, and for the recruitment of the ranks. Both these resources he estimated very highly, and as Tennessee was still claimed as a seceding State, the Confederate conscription laws would be enforced there. On the other hand, every movement in retreat cut off a part of their area for supplies and men, was discouraging to the army, and was followed by numerous desertions of soldiers whose families were within our lines.
