Grant informed Butler of his recall on January 8, 1865, and named Major General Edward O. C. Ord to replace him as commander of the Army of the James. Rather than report to Lowell, Butler went to Washington, where he used his considerable political connections to get a hearing before the Joint Congressional Committee on the Conduct of the War in mid-January. At his hearing Butler focused his defense on his actions at Fort Fisher. He produced charts and duplicates of reports by subordinates to prove he had been right to call off his attack of Fort Fisher, despite orders from General Grant to the contrary. Butler claimed the fort was impregnable. To his embarrassment, a follow-up expedition led by Maj. Gen. Alfred H. Terry and Brig. Gen. Adelbert Ames (Butler's future son-in-law) captured the fort on January 15, and news of this victory arrived during the committee hearing; Butler's military career was over. He was formally retained until November 1865 with the idea that he might act as military prosecutor of Confederate President Jefferson Davis.
