"WASHINGTON, September 17, 1841.

" Dear Sir :—You wish to know of me, what I know of the conduct of Colonel Sidney Sherman, before and after the battle of San Jacinto. On our march to that place, Colonel Sherman often asked me.if I had heard you speak of him. I informed him that I had heard you speak of him. and always in the highest terms of praise. I thought he looked disappointed. There was mutiny and discontent in the army, created, as I believed, by those who wished to put you down; and I believed that Colonel Sherman was one of the most active in creating disturbance, as I will have occasion to show.

" Various councils were held on the Brazos, as well as on the march to San Jacinto, for the purpose of opposing or destroying your authority. Colonel Sherman, I am satisfied, was among the most active of those who sought to destroy you. On the 2oth of April, the day before the battle of San Jacinto, you gave Colonel Sherman orders to charge on an island of timber, on the left of the artillery, with two companies of his regiment, for the purpose of routing some Mexicans who were in the timber. He wished you to let him charge on horseback, which you reluctantly granted. As he approached the enemy they fired and killed one horse of his command, and the whole command came galloping back to the camp. In the evening, when the enemy had withdrawn to where they fortified, at his request, you ordered Colonel Sherman to take the cavalry and reconnoiter the enemy, and if he could decoy the enemy's cavalry to a certain island of timber, that the artillery and infantry should be there to sustain him, but by no means to approach within gun-shot of the enemy's infantry or line.

" I was present when you gave the orders to Colonel Sherman, and soon after he came to me and asked me if I would sustain him, as he had determined to bring on a general engagement, contrary to your orders. At the same time, the officer with him said he had agreed to sustain him with his command. I replied that I knew it was contrary to your orders to him, for I heard you give them to him; but, if a general engagement was brought on, my regiment would be under arms, and I would support him ; for you had ordered me to have the men under arms. He departed, saying he would depend on me. He soon commenced firing after he was out of sight of our camp; and, as it had not been expected from the orders given by you to him, there was great stir in the camp. I started with my command, and in marching a short distance, I saw the cavalry returning with two wounded men. In the meantime, Colonel Wharton, from you, ordered me not to advance, but to wait further orders. You afterward ordered me, with my command, back to our camp, and showed evident dissatisfaction with Sherman for disobeying your orders, in attempting to bring on a general engagement, when you did not intend it should be done. It was then late in the evening of the 2oth.

"After the arrival of General Cos' command, next morning (21st), and 1 think it was between twelve and two o'clock, I was summoned to attend a council of war. I attended with six other field officers, when you told us the object of our being called together. You asked the council' whether we should attack the enemy, or remain in our position and \lef\ the enemy attack us.'

-' The officer lowest in rank voted first, and so on, until all voted. Only two out of the seven voted for attacking the enemy. The balance voted in faver of awaiting the attack upon us. They said that we had not bayonets to charge with, and that it was through an open prairie ; that our position was strong, and in it we could whip all Mexico.

" When you received the sense of the council, you gave no opinion, but dismissed the members. Soon after, I was riding out to graze my horse and take a look at the enemy. You spoke to me, and asked me my object in riding out. I told you, when you said, 'Do not be absent. Colonel, more than thirty minutes, as I will want you.' I did return in less than a half hour; you requested me to see my captains and men, and ascertain their feelings about fighting. I reported favorably, and said they were anxious to fight, or they told many lies. You ordered the troops to be paraded; the second regiment, called Sherman's, as he was Colonel, and myself Lieutenant-Colonel. Soon after you ordered the parade, Colonel Sherman, in company with Colonel Burleson, came to me, and asked me if I intended to obey your orders, and if I did not think it would be better to wait until next morning, just before day, and make the attack. Sherman went on to say that whatever I said should be done. I told him that I would fight, if you said so, and that I would follow you to h—1, if you would lead, in defending  Texas. They then left me. When Colonel Sherman and myself were mounted, at the head of the regiment, he asked me if I would take command that day, as I had some experience in fighting, and he never had been in a battle. I thanked him kindly, saying that I would do so, and after we were ordered to advance, he rode with me until the enemy commenced firing upon us. Colonel Sherman then left in great haste for a small island of timber, about three hundred yards distant, in the rear of our left wing, where he secured himself, and remained there until the enemy had all fled. As I returned from the pursuit of the enemy, I met him coming up with some stragglers.

" This statement is made principally from notes taken during the campaign, and from facts within my recollection, as though they had passed yesterday. I have forborne to state anything about Colonel Sherman's conduct in disposing of, and appropriating the spoils privately to his own use; but, should it be necessary at any future day to do so, I am fully prepared.

" I am your friend, etc., JOSEPH L BENNETT
