While they were eating, the house was surrounded by Union cavalry. Mosby rushed to the back door, to find the backyard full of soldiers. He started for the front door, but as he did, it burst open and a number of Yankees, officers and men, entered the house. At the same time, the soldiers behind, having seen the back door open and shut, began firing at the rear windows, and one bullet hit Mosby in the abdomen. In the confusion, with the women of the Lake family screaming, the soldiers cursing, and bullets coming through the windows, the kitchen table was overturned and the lights extinguished. Mosby in the dark, managed to crawl into a first-floor bedroom, where he got off his tell-tale belt and coat, stuffing them under the bed. Then he lay down on the floor.
After a while, the shooting outside stopped, the officers returned, and the candles were relighted. The Union officers found Mosby on the floor, bleeding badly, and asked the family who he was. They said, of course, that they did not know, and neither did Tom Love—he was only a Confederate officer on his way to rejoin his command, who had stopped for a night's lodging. There was a surgeon with the Union detachment. After they got most of Mosby's clothes off and put him on the bed, he examined the wounded Confederate and pronounced his wound mortal. When asked his name and unit, Mosby, still conscious, hastily improvised a false identity, at the same time congratulating himself on having left all his documents behind when starting on this scouting trip. Having been assured, by medical authority, that he was as good as dead, the Union officers were no longer interested in him and soon went away.
Fortunately, on his visit to Lee's headquarters, Mosby had met an old schoolmate, a Dr. Montiero, who was now a surgeon with the Confederate Army, and, persuading him to get a transfer, had brought him back with him. Montiero's new C.O. was his first patient in his new outfit. Early the next morning, he extracted the bullet. The next night Mosby was taken to Lynchburg.
Despite the Union doctor's pronouncement of his impending death, Mosby was back in action again near the end of February, 1865. His return was celebrated with another series of raids on both sides of the mountains. It was, of course, obvious to everybody that the sands of the Confederacy were running out, but the true extent of the debacle was somewhat obscured to Mosby's followers by their own immediate successes. Peace rumors began drifting about, the favorite item of wish-thinking being that the Union government was going to recognize the Confederacy and negotiate a peace in return for Confederate help in throwing the French out of Mexico. Of course, Mosby himself never believed any such nonsense, but he continued his attacks as though victory were just around the corner. On April 5, two days after the Union army entered Richmond, a party of fifty Mosby men caught their old enemies, the Loudoun Rangers, in camp near Halltown and beat them badly. On April 9, the day of Lee's surrender, "D" Company and the newly organized "H" Company fired the last shots for the Forty-Third Virginia in a skirmish in Fairfax County. Two days later, Mosby received a message from General Hancock, calling for his surrender.
He sent a group of his officers—William Mosby, Sam Chapman, Walter Frankland and Dr. Montiero—with a flag of truce, and, after several other meetings with Hancock, the command was disbanded and most of the men went in to take the parole.
When his armistice with Hancock expired, Mosby found himself with only about forty irreconcilables left out of his whole command. As General Joe Johnston had not yet surrendered, he did not feel justified in getting out of the fight, himself. With his bloodied but unbowed handful, he set out on the most ambitious project of his entire military career—nothing less than a plan to penetrate into Richmond and abduct General Grant. If this scheme succeeded, it was his intention to dodge around the Union Army, carry his distinguished prisoner to Johnston, and present him with a real bargaining point for negotiating terms.
They reached the outskirts of Richmond and made a concealed camp across the river, waiting for darkness. In the meanwhile, two of the party, both natives of the city, Munson and Cole Jordan, went in to scout. Several hours passed, and neither returned. Mosby feared that they had been picked up by Union patrols. He was about to send an older man, Lieutenant Ben Palmer, when a canal-boat passed, and, hailing it, they learned of Johnston's surrender.
That was the end of the scheme to kidnap Grant. As long as a Confederate force was still under arms, it would have been a legitimate act of war. Now, it would be mere brigandage, and Mosby had no intention of turning brigand.
So Mosby returned to Fauquier County to take the parole. For him, the fighting was over, but he was soon to discover that the war was not. At that time, Edwin M. Stanton was making frantic efforts to inculpate as many prominent Confederates as possible in the Booth conspiracy, and Mosby's name was suggested as a worthy addition to Stanton's long and fantastic list of alleged conspirators. A witness was produced to testify that Mosby had been in Washington on the night of the assassination, April 14. At that time, Stanton was able to produce a witness to almost anything he wanted to establish. Fortunately, Mosby had an alibi; at the time in question, he had been at Hancock's headquarters, discussing armistice terms; even Stanton couldn't get around that.
