I captured a "secesh" horse found running loose,--for my own horse had been killed and I had been afoot quite a long time,--mounted him, and as son as the state of the contest would permit, I rode to Major Sturgis, informed him of Lyon's death, and told him he must assume the command, which he accordingly did. It afterward appeared that there was one lieutenant-colonel of volunteers remaining on the field, but neither he nor any one else thought of questioning the propriety of Major Sturgis's taking the command. Soon after Lyon's death the enemy was repulsed, but then seemed to gather up all his remaining strength for a last effort. His final attack was heavier than any of the preceding, but it was more firmly met by our troops and completely repulsed. There is probably no room for doubt that the enemy was beaten if we had but known it; but the battle-field was covered with timber and underbrush, so that nothing could be seen beyond a few hundred yards. Our troops were nearly out of ammunition, and exhausted by a night march and by six hours' hard fighting without breakfast.
It did not seem possible to resist another such attack as the last, and there was no apparent assurance that another would not be made. Hence Major Sturgis decided to withdraw from the field while he was free to do so. The movement was effected without opposition, the wounded were brought off, and the command returned to Springfield in the afternoon. This retreat was undoubtedly an error, and the battle of Wilson's Creek must be classed as a defeat for the Union army. The error was a failure to estimate the effect that must have been produced upon the enemy as well as upon ourselves by so much hard fighting. It was only necessary to hold our ground, trusting to the pluck and endurance of our men, and the victory would have been ours. Had Lyon, who was in the front of the line of battle when wounded as well as when killed, appreciated this fact and acted upon it, instead of throwing his life away, it is safe to say he would have won a brilliant victory.
On the march from the battle-field the main body was joined by the remnant of Sigel's brigade, which had made a complete circuit in rear of the enemy's position. They were without brigade or regimental commanders, and were escorted by a troop of regular cavalry. On our arrival in Springfield it was found that Colonel Sigel and Colonel Salomon, commanding the 5th Missouri Regiment, of Sigel's brigade, had arrived in town some hours before. Major Sturgis then relinquished the command to Colonel Sigel, and it was determined to retreat toward Rolla next morning. Sigel's brigade was placed in advance, and Sturgis's brigade of regulars was assigned the important post of rear-guard. This order of march was continued during three days, and the march was so conducted that while the advance would reach camp at a reasonable hour and be able to get supper and rest, the rear-guard, and even the main body, would be kept in the road until late in the night, and then, unable to find their wagons, be compelled to lie down without food. The clamor for relief from this hardship became so general that Major Sturgis determined to resume the command, justifying this action upon the ground that Colonel Sigel, although mustered into the United States service, had no commission from any competent authority. Colonel Sigel protested against this assumption of Major Sturgis, but the latter was so manifestly sustained by the great majority of the officers of the army that Colonel Sigel quietly submitted.
