up and stirring at four on the morning of April 7. The General himself roused his command quietly by riding through the bivouac. At five, he was able to report to General Buell, by an aide-de-camp, that his line of battle with skirmishers in front was ready to move, and received orders to advance on the enemy. Crittenden advanced simultaneously on Nelson's right. I followed in the rear with the ambulances. At half-past five the first shots fell, and, in a few minutes, the musketry-firing was heavy, and presently hostile balls and shells were whizzing over us.
