Another logical fallacy was the statement that if Colt hadn’t supplied revolvers to the North, the war might have turned out differently. In any major situation, all sorts of variables were employed. If the North had issued Henry rifles to all their troops at the start of the war instead of the Springfield musket, the war might have been shortened considerably as well. But Colt did supply revolvers, and the troops weren’t given Henry rifles as standard issue. (Although some Federal troops had repeating rifles like the Spencer, and a few purchased Henry’s out of their own pocket.) Britain might have come in on the side of the South. All sorts of variables. That’s history for you.
Prince Albert, on his deathbed requested the prime minister not recognize the pretended confederacy as he thought it morally wrong to support slavery. I don’t think that would have changed because of opportunity to sell a few rifles or pistols.
