All of the colonies thereafter tended to look more favorably upon the enlistment of colored troops. Free Negroes enlisted in Virginia and so many slaves deserted their masters for the army that the State enacted in 1777 a law providing that no Negro should be enlisted unless he had a certificate of freedom.[36] That commonwealth, however, soon took another step toward greater recognition of the rights of the Negroes who desired to be free to help maintain the honor of the State. With the promise of freedom for military service many slaves were sent to the army as substitutes for freemen. The effort of inhuman masters to force such Negroes back into slavery at the close of their service at the front actuated the liberal legislators of that commonwealth to pass the Act of Emancipation, proclaiming freedom to all Negroes who had thus enlisted and served their term faithfully, and empowered them to sue _in forma pauperis_, should they thereafter be unlawfully held in bondage.[37] In the course of time there arose an urgent need for the Negro in the army. The army reached the point when almost all sorts of soldiers were acceptable. In 1778 General Varnum induced General Washington to send certain officers from Valley Forge to Rhode Island to enlist a battalion of Negroes to fill the depleted ranks of that State.[38] Setting forth in the preamble that "history affords us frequent precedents of the wisest, freest and bravest nations having liberated their slaves and enlisted them as soldiers to fight in defense of their country," the Rhode Island Assembly resolved to raise a regiment of slaves, who were to be freed upon their enlistment, their owners to be paid by the State according to the valuation of a committee. Further light was thrown upon this action in the statement of Governor Cooke, who in reporting the action of the Assembly to Washington boasted that liberty was given to every effective slave to don the uniform and that upon his passing muster he became absolutely free and entitled to all the wages, bounties and encouragements given to any other soldier.[39]
