I have not been so fortunate as to have a poet to do for me on this occasion what Longfellow did for the midnight ride of Paul Revere. There was a drizzling rain and a dense fog; it was impossible to see what the enemy were doing. I remember Stuart's joy and surprise when I told him that they were falling back from the river. In the rapture of the moment he told me that I could get any reward I wanted for what I had done. The only reward I asked was the opportunity to do the same thing again.[23] In ten minutes the cavalry had crossed the river and was capturing prisoners. Nothing had been left before us but a screen of cavalry, which was quickly brushed away. It now became evident that McClellan would move down the Potomac and operate against Richmond from a new base and on another line. This was the first cavalry reconnoissance that had ever been made to the rear of the enemy, and was considered as something remarkable at that time; at a later period they were very common. Soon after this, Stuart's cavalry was transferred from the line of the Rappahannock with the rest of Johnston's army, to confront McClellan on the Peninsula. I dined with Gen. Lee at his headquarters, near Petersburg, about six weeks before the surrender. He told me then that he had been opposed to Gen. Johnston's withdrawing to the Peninsula, and had written to him while he was on the Rapidan, advising him to move back towards the Potomac. He thought that if he had done this, McClellan would have been recalled to the defence of Washington. He further said that, instead of falling back from Yorktown to Richmond, Gen. Johnston should have made a stand with his whole army, instead of a part of it, on the narrow isthmus at Williamsburg.

Just before we reached Williamsburg, news came of the passage of the conscription law, which preserved all the regimental organizations as they were. The men were held in the ranks, but allowed to elect their company officers; and these in turn elected field officers. It is hard to reconcile democracy with military principles; and, consequently, many of the best officers were dropped. Such was the fate of my colonel. The staff officers, not being elected, were supposed to hold over without reappointment. I immediately handed my resignation as adjutant to the new colonel,—Fitz Lee,—who accepted it.

The conscription law at first produced some dissatisfaction among the men, as most of them had served twelve months without a furlough; but this soon subsided. All acquiesced in what was regarded as imperious necessity. The loss of our positions in the First Virginia Cavalry resulted in a benefit both to Jones and myself. Through the influence of Stonewall Jackson, Jones was made a brigadier-general, and soon after the death of Ashby was given the command of his brigade. Stuart invited me to come to his headquarters and act as a scout for him. In this way I began my career as a partisan, which now, when I recall it through the mist of years, seems as unreal as the lives of the Paladins.

I wish it to be understood that a scout is not a spy who goes in disguise, but a soldier in arms and uniform who reconnoitres either inside or outside an enemy's line. Such a life is full of adventure, excitement, and romance. Stuart was not only an educated, but a heaven-born soldier, whose natural genius had not been stifled by red tape and the narrow rules of the schools.

The history of the war furnishes no better type of the American soldier; as a chief of cavalry he is without a peer. He cared little for formulas, and knew when to follow and when to disregard precedents. He was the first to see that the European methods of employing cavalry were not adapted to the conditions of modern war.[24] His inventive genius discovered new ways of making cavalry useful, that had never been dreamed of by the regular professors of the science. I will now give some illustrations of his originality and the fertility of his resources. When McClellan was lying in the swamps of the Chickahominy, the infantry lines of the two armies were so close together that cavalry operations in their front were impracticable. One morning, when Stuart's headquarters were near Richmond, he invited me to breakfast with him, and at the table asked me to take two or three men and find out whether McClellan was fortifying on the Totopotomoy Creek. I had been inactive for some time, and this was just the opportunity I wanted. I started, but was diverted from the route I had been directed to go by there being a flag of truce on the road. I did not want to return without accomplishing something, so I turned north and made a wide detour by Hanover Court House. Although I was then engaged in the business of breaking idols, I had not lost all reverence for antiquity. I stopped a while to muse in the old brick building where Patrick Henry made his first speech at the bar, and pleaded the cause of the people against the parsons. In order to understand the enterprise on which I was going, a geographical description of the country and situation of the armies is necessary. The battle of Fair Oaks or Seven Pines had been fought, and the army of the Potomac was lying on the Peninsula between the James and Pamunkey rivers, and astraddle of the Chickahominy, which meanders between them and finally empties into the James. McClellan's right wing rested on the Pamunkey, with his base at the White House and his line of supply by the York River Railroad. His left extended to within a few miles of the James. The Totopotomoy Creek flows into the Pamunkey. I got down in the enemy's lines on the Totopotomoy and ascertained that six or eight miles of McClellan's front was a mere shroud of cavalry pickets that covered his line of communication with his depot at the White House. Of course, as he had no infantry on his right there would be no fortifications there. The idea immediately occurred to me that here was a grand opportunity for Stuart to strike a blow. It is now clear why General Lee wanted to get information about the enemy's fortifying the Totopotomoy.

About three weeks after that he called Jackson from the valley, who struck McClellan on this very ground. I was chased away from there and came out just behind a regiment of Union cavalry going on a scout. They very little thought that I was coming back so soon. I hastened to Stuart's headquarters to give him the information. Everybody there was in high glee. News had just come of Jackson's victories over Fremont and Shields: Cross Keyes and Port Republic had been inscribed on his banners. It was a hot day in June, and Stuart was sitting under the shade of a tree, and I lay down on the grass to tell him what I had learned. After giving him the information, I remarked, that as the cavalry was idle, he could find on the Pamunkey something for them to do. A blow on this weak point would greatly alarm McClellan for the safety of his supplies, and compel him to detach heavily from his front to guard them. After I got through, he said to me, "Write down what you have told me." I went to his adjutant's office and wrote it down hurriedly; but, not attaching much importance to it, did not sign the writing. When I brought the paper to Stuart he had his horse ready to mount. He called my attention to the omission, and I went back and signed it. He started off at a gallop with a single courier to General Lee's headquarters. He returned that afternoon, and orders were immediately issued for a part of the cavalry to get ready to march.

General Lee's instructions to Stuart, directing, or rather authorizing, the expedition, are dated June 11, which shows how soon he started after my return, which was on the 10th.[25] With about 1200 cavalry and two pieces of artillery, on the morning of June 12, Stuart left Richmond, moving in a northerly direction, to create the impression that he was going to reinforce Jackson. That night we bivouacked within a few miles of Hanover Court House. During his absence his adjutant was left in charge of his headquarters. I was present when he started. The adjutant asked him how long he would be gone. Stuart's answer was, "It may be for years, and it may be forever." Taking leave of his staff had suggested the parting from Erin and Kathleen Mavourneen.

There were many surmises as to his destination; but I never doubted for a moment where we were going. Early the next morning Stuart sent me on in advance with a few men to Hanover Court House, and I then saw that my idea of a raid on McClellan's lines was about to be realized. When we got within a few hundred yards of the village, a squadron of cavalry was discovered there, and I sent a man back to inform Stuart of it, so that he might send a regiment round to cut off their retreat. He ordered the First Virginia Cavalry to go; but the enemy, suspecting that there was a stronger force than they could see, withdrew too soon to be caught.

The column then pushed rapidly towards the camp of Union cavalry at Old Church. At that place Captain Royall was stationed with two squadrons of the 5th U.S. regular cavalry. There was a running fight of several miles with the pickets, and finally we met Captain Royall, who came out with his whole command to reinforce the outpost. He had no suspicion of the number he was attacking, and as soon as he came in sight, Stuart ordered the front squadron of the 9th Virginia cavalry to charge. Royall was wounded and routed. On our side, Captain Latané was killed. We could not stay to give him even the hasty burial that the hero received who died on the ramparts of Corunna. This was left for female hands to do. The scene has been preserved on canvas by a Virginia artist. As Royall's command had been scattered, we soon had possession of his camp, and were feasting on the good things we found in it. Nearly everybody forgot—many never knew—the danger we were in. A mile or so on our left was an impassable river—not more than six miles to the right were McClellan's headquarters, with Fitz John Porter's corps and the reserve division of cavalry camped near us. Here was the turning-point of the expedition. Stuart was as jolly as anybody; but his head was always level in critical moments—even in the midst of fun. There was a short conference between him and the Lees, who were the colonels of the two Virginia regiments. I was sitting on my horse, buckling on a pistol I had just captured, within a few feet of them and heard all that passed. Stuart was for pushing on to the York River Railroad, which was still nine miles off. Lee, of the 9th (son of General R. E. Lee), was in favor of it, but Fitz Lee was opposed. Stuart had no idea of turning back, and determined to go on and strike McClellan in his rear. In the conception and execution of this bold enterprise he showed the genius and the intrepid spirit that took the plunge of the Rubicon.

Just as he gave the command, "Forward!" he turned to me, and said, "Mosby, I want you to ride some distance ahead." I replied: "Very well. But you must give me a guide; I don't know the road." He then ordered two cavalrymen who were familiar with the country to go with me; and I started on towards Tunstall's station. I was on a slow horse; and I remember that I had not gone very far before Stuart sent one of his staff to tell me to go faster and increase the distance between us. It was important that we should reach the railroad before dark, or reinforcements could be sent there. So I went on with my two men at a trot.[26]
