All the troops we had to counteract Buckner were Rousseau’s Legion, and a few Home Guards in Louisville.  The former were still encamped across the river at Jeffersonville; so General Anderson ordered me to go over, and with them, and such Home Guards as we could collect, make the effort to secure possession of Muldraugh’s Hill before Buckner could reach it.  I took Captain Prime with me; and crossed over to Rousseau’s camp.  The long-roll was beaten, and within an hour the men, to the number of about one thousand, were marching for the ferry-boat and for the Nashville depot.  Meantime General Anderson had sent to collect some Home Guards, and Mr. Guthrie to get the trains ready.  It was after midnight before we began to move.  The trains proceeded slowly, and it was daybreak when we reached Lebanon Junction, twenty-six miles out, where we disembarked, and marched to the bridge over Salt River, which we found had been burnt; whether to prevent Buckner coming into Louisville, or us from going out, was not clear.  Rousseau’s Legion forded the stream and marched up to the State Camp of Instruction, finding the high trestles all secure.  The railroad hands went to work at once to rebuild the bridge.  I remained a couple of days at Lebanon Junction, during which General Anderson forwarded two regiments of volunteers that had come to him.  Before the bridge was done we advanced the whole camp to the summit of Muldraugh’s Hill, just back of Elizabethtown.  There I learned definitely that General Buckner had not crossed Green River at all, that General Sidney Johnston was fortifying Bowling Green, and preparing for a systematic advance into Kentucky, of which he was a native, and with whose people and geography he must have been familiar.  As fast as fresh troops reached Louisville, they were sent out to me at Muldraugh’s Hill, where I was endeavoring to put them into shape for service, and by the 1st of October I had the equivalent of a division of two brigades preparing to move forward toward Green River.  The daily correspondence between General Anderson and myself satisfied me that the worry and harassment at Louisville were exhausting his strength and health, and that he would soon leave.  On a telegraphic summons from him, about the 5th of October, I went down to Louisville, when General Anderson said he could not stand the mental torture of his command any longer, and that he must go away, or it would kill him.  On the 8th of October he actually published an order relinquishing the command, and, by reason of my seniority, I had no alternative but to assume command, though much against the grain, and in direct violation of Mr. Lincoln’s promise to me.  I am certain that, in my earliest communication to the War Department, I renewed the expression of my wish to remain in a subordinate position, and that I received the assurance that Brigadier-General Buell would soon arrive from California, and would be sent to relieve me.  By that time I had become pretty
