Since you apparently believe that blacks only fought for Rhode Island in the Revolutionary War, I believe it safe to assume you don't know lots of things. Black Americans, slave and free, fought in the Regiments and Militias of many of the colonies. And they refused British bribes of immediate emancipation to do so.
Inspector Steiner's report would have to be read in its entirety in order to know what he really said
Maybe he said what he said. How about Frederick Douglass? Here's what he had to say about black SOLDIERS in the Confederate Army:
"There are at the present moment many colored men in the Confederate army doing duty not only as cooks, servants and laborers, but as real soldiers, having muskets on their shoulders, and bullets in their pockets, ready to shoot down loyal troops, and do all that soldiers may to destroy the Federal Government and build up that of the traitors and rebels. There were such soldiers at Manassas, and they are probably there still...Rising above vulgar prejudice, the slaveholding rebel accepts the aid of the black man as readily as that of any other." - Frederick Douglass, 1861.
Even Horace Greeley, yet another REPUBLICAN, mentioned the fact that black soldiers were in the Southern Confederate Army, and not segregated into one-color units either:
"For more than two years, Negroes have been extensively employed in belligerent operations by the Confederacy. They have been embodied and drilled as rebel soldiers and had paraded with white troops at a time when this would not have been tolerated in the armies of the Union."
Maybe Frederick Douglass and Horace Greeley were really secret democrats...at any rate, your continued attempts to deny black Americans of their historical contributions do not help the Republican Party. In fact, they contribute greatly to further the current democrat stereotypes of it.
