There are other causes that deter me from giving this bill the sanction of my approval. The judgment of the court-martial by which more than twenty years since General Fitz John Porter was tried and convicted was pronounced by a tribunal composed of nine general officers of distinguished character and ability.

The officers who constituted it, in their report to the Secretary of War, dated March 19, 1879, state that in their opinion—
