« At the time when Gen. Grant's character and probable usefulness were unknown quantities, Mr. Dana's confidence in Grant's military ability probably did much to defeat the powerful effort then making to break down the rising commander. Of this critical period Gen. Sherman remarks in his “Memoirs”: “One day early in April, 1863, I was up at Grant's headquarters [at Vicksburg], and we talked over all these things with absolute freedom. Charles A. Dana, assistant secretary of war, was there, and Wilson, Rawlins, Frank Blair, McPherson, etc. We all knew, what was notorious, that Gen. McClernand was intriguing against Gen. Grant, in hopes to regain command of the whole expedition, and that others were raising clamor against Grant in the newspapers of the north. Even Mr. Lincoln and Gen. Halleck seemed to be shaken; but at no instant did we (his personal friends) slacken in our loyalty to him. » in Appleton's Cyclopedia of American Biography :
