In the very beginning of the Thirty-seventh Congress there came a series of antislavery measures which constituted a complete and decisive reversal of the policy of the Federal Government.[30] On March 13, 1862, Congress approved an act, which prohibited all military and naval officers and enlisted personnel from returning fugitive slaves. Section 10 of the Confiscation Act, virtually an amendment of the Fugitive Slave Law, which withheld from the claimant the right to use his authority until he had taken an oath of allegiance, and made it tantamount to a crime for any person in the army or navy to surrender a fugitive slave or attempt to validate the owner's claim, was rigidly enforced. Wishing to see Liberia and Haiti welcomed into the family of nations, moreover, Lincoln in his annual message in the previous December recommended the recognition of their independence and the establishment of diplomatic relations with the new nations. This resolution was passed by a Congress and approved June 5, 1862. Lincoln then effected the passage of a measure to carry into execution the treaty between Great Britain and the United States for the suppression of the African slave trade. Soon thereafter followed an act to secure freedom to all persons within the territories of the United States. The Republican party had thus carried out its platform by its restoration of the Missouri Compromise, its extension and application to all Territories, and as a logical result the rejection and condemnation of the Dred Scott decision and the subversive property theory of the secessionists.[31] Then followed the Confiscation Act, the discussion of which was closely followed by Lincoln, who had his views incorporated therein by pointing out its defects and suggesting amendments. Whereas the act of August 6, 1861, freed slaves actually employed in military service, the new Confiscation Act of 1862 proved to be a law to destroy slavery under the powers of war. In conjunction with provisions for punishing treason or rebellion it declared free all slaves of persons guilty and convicted of these crimes, and provided that slaves deserted by rebels escaping from them or coming under control of the United States and slaves of rebels found on Union soil should be deemed captives and set free. Then again, there were enacted other provisions, which by implication permitted the employment of slaves in the United States army that they might work their own enfranchisement. Under this law the President was empowered to enroll and employ contrabands in such service as they were fitted for. Their mothers, wives, and children, if owned by rebels, should be declared free by virtue of such service. The eleventh section of the Confiscation Act authorized the President to employ as many Negroes as he might deem necessary for the suppression of the rebellion. The organization of the earliest Negro regiments resulted from this legislation.
