Such an institution, from its wide powers, great responsibilities, large control of moneys, and generally conspicuous position, was naturally open to repeated and bitter attacks. It sustained a searching congressional investigation at the instance of Fernando Wood in 1870. It was, with blunt discourtesy, transferred from Howard's control, in his absence, to the supervision of Secretary of War Belknap in 1872, on the Secretary's recommendation. Finally, in consequence of grave intimations of wrongdoing made by the Secretary and his subordinates, General Howard was court-martialed in 1874. In each of these trials, and in other attacks, the commissioner of the Freedmen's Bureau was exonerated from any willful misdoing, and his work heartily commended. Nevertheless, many unpleasant things were brought to light: the methods of transacting the business of the Bureau were faulty; several cases of defalcation among officials in the field were proven, and further frauds hinted at; there were some business transactions which savored of dangerous speculation, if not dishonesty; and, above all, the smirch of the Freedmen's Bank, which, while legally distinct from, was morally and practically a part of the Bureau, will ever blacken the record of this great institution. Not even ten additional years of slavery could have done as much to throttle the thrift of the freedmen as the mismanagement and bankruptcy of the savings bank chartered by the nation for their especial aid. Yet it is but fair to say that the perfect honesty of purpose and unselfish devotion of General Howard have passed untarnished through the fire of criticism. Not so with all his subordinates, although in the case of the great majority of these there were shown bravery and devotion to duty, even though sometimes linked to narrowness and incompetency.
