In answering Longstreet, Johnston had said that he would execute zealously any plan the President would order; but he evidently insisted on definite and formal commands if he were to depart from his preconceived views to which he held tenaciously. On the 16th of March he wrote again, this time in answer to Bragg's of the 7th. After telling of the impossibility of collecting artillery horses in northern Georgia, he mentions Longstreet's letter to him, to say that he thinks the point of junction suggested is too near the enemy, and that his army should have an accumulation of eighteen or twenty days' supplies before entering upon such a movement. They must also have ordnance stores for a campaign, and wagon trains to carry it all. [Footnote: Official Records, vol. xxxii. pt. iii. p. 636.] Two days later he received Bragg's full letter of the 12th sent by the hand of Colonel Sale as special messenger, and he now answers by telegraph. He says that Grant is back at Nashville, and is not likely to stand on the defensive. To meet at Dalton his expected advance, the reinforcements that had been spoken of must be sent at once. "Give us those troops," he says; "and if we beat him we follow. Should he not advance, we will thus be ready for the offensive. The troops can be fed as easily here as where they now are." [Footnote: _Id_., p. 649.] Next day he elaborated the same ideas in a letter, adding the suggestion before made by him that the line of advance by way of North Alabama was a preferable one to the route through East Tennessee. The telegram was answered from Richmond whilst the longer letter was on its way. The answer conveyed the information that Grant would not personally lead the western army, but would turn over its command to Sherman. It also briefly noted the fact that Johnston had not accepted the aggressive policy on which the large reinforcements were made conditional. [Footnote: I do not find this dispatch in the Official Records. It is given in Johnston's "Narrative of Military Operations," p. 298.] He replied that his dispatch expressly accepted taking the offensive, and the only difference was as to details. He therefore repeats the urgent request that the troops be sent at once. [Footnote: Official Records, vol. xxxii. pt. iii. p. 666.]
