“Captain John S. Mosby has for a long time attracted the attention of his generals by his boldness, skill and success, so signally displayed in his numerous forays upon the invaders of his native State. None know his daring enterprise and dashing heroism better than these foul invaders though strangers themselves to such noble traits. His late brilliant exploit, the capture of General Stoughton, U. S. A., two captains, thirty other prisoners, together with their arms, equipments and fifty-eight horses, justifies this recognition in General Orders. The feat, almost unparalleled in the war, was performed in the midst of the enemy’s troops, at Fairfax Court House, without loss to Virginia. The gallant band of Captain Mosby share the glory as they did the danger of this enterprise, and are worthy of such a leader.” Secretary of War Stanton was very angry over the incident. He felt that it was the result of bad management in permitting Union secrets to be discovered by the enemy and he was determined to know just how it had happened. Secretary Stanton sent for General Lafayette C. Baker, then Chief of the Federal Secret Service, and instructed him to make a thorough investigation and to make any arrests that might be deemed necessary. Baker had already made a survey of the grounds at Fairfax Court House, and was familiar with the incidents of the raid. He was perfectly satisfied that the Union soldiers had been betrayed by a spy. And he came to another important conclusion. It was that the work had been done by a woman spy! How could he ascertain the identity of the woman and how could he prove her guilt? These were not the sort of questions to be easily answered. Baker suspected the daughter of one of the leading citizens of Fairfax Court House, but he had too much experience in handling delicate matters of the war to think of arresting a woman without having proof of her guilt. It would not do to place the case in the hands of the soldiers. Their methods were likely to be crude, and besides might cause complications. He thought over the matter for some time and then he made a momentous decision. He decided to place the case in the hands of a woman operative in his own office. It was to be a case of woman against woman!
