True to his nature, Grant did not panic at the Confederate assault. As Grant rode back from the river, he heard the sounds of guns and sent word to Foote to begin a demonstration of naval gunfire, assuming that his troops would be demoralized and could use the encouragement. Grant observed that some of the Confederates (Buckner's) were fighting with knapsacks filled with three days of rations, which implied to him that they were attempting to escape, not pressing for a combat victory. He told an aide, "The one who attacks first now will be victorious. The enemy will have to be in a hurry if he gets ahead of me."
