This bill was the _pièce de résistance_ of senatorial debate for the whole session. Its confiscatory features were attacked on the 4th of March by Senator Cowan, in a speech of great force. Cowan was a new Senator from Pennsylvania, a Republican of conservative leanings, and a great debater. He opposed the bill on grounds of both constitutionality and expediency. On the 24th of April, Collamer, of Vermont, expressed the sound opinions that private property could not be confiscated except by judicial process, and that even if it could be done it would be bad policy, since it would tend to prolong the war and would constitute a barrier against future peace. The Confederate Government had led the way by passing a law (May 21, 1861) sequestrating all debts due to Northern individuals or corporations and authorizing the payment of the same to the Confederate Treasury. The whole subject was extremely complex. "There was commonly," says a recent writer in the _American Historical Review_, "a failure in the debates to discriminate between a general confiscation of property within the jurisdiction of the confiscating government and the treatment accorded by victorious armies to private property found within the limits of military occupation. Thus the general rule exempting private property on land from the sort of capture property must suffer at sea, was erroneously appealed to as an inhibition upon the right of judicial confiscation. That a military capture on land analogous to prize at sea was not regarded as a legitimate war measure was so obvious and well recognized a principle that it would hardly require a continual reaffirmation. It was a very different matter, however, so far as the law and practice of nations was concerned, for a belligerent to attack through its courts whatever enemy's property might be available within its limits."[55] Collamer offered an amendment to strike out the first section of the bill and insert a clause providing that every person adjudged guilty of the crime of treason should suffer death, or, at the discretion of the court, be imprisoned not less than five years and fined not less than ten thousand dollars, which fine should be levied on any property, real or personal, of which he might be possessed. The fine was to be in lieu of confiscation. The aim of the amendment was to substitute due process of law in place of legislative forfeiture. Various other amendments were offered. On the 6th of May, the Senate voted by 24 to 14 to refer the bill and amendments to a select committee of nine. The House, which had been waiting for the Senate bill, decided on the 14th of May to take up a measure of its own, which it passed on the 26th. The select committee of the Senate framed a measure regarding the emancipation of escaping slaves. This and the House bill were sent to a conference committee, which reported the bill which became a law July 17, 1862.
