If Wikipedia is to be believed, Confederate general Beauregard was offered important military positions for several different countries in the years following the American Civil War, including leadership of the Bulgarian army. However, he declined all of these offers, happy with the relatively conciliatory policies of President Andrew Johnson and his successors toward former Confederate officers. However, what if, for whatever reason (say, perhaps a hardline Radical Republican presidency), Beauregard had taken up an offer from the Bulgarians, then revolting against the Ottoman Empire, to lead their armies during the greater Russo-Turkish War of 1877-1878? Would the Bulgarians have done better in the war? Worse? If the former, would they have had the leverage to secure the borders promised to them by the Treaty of San Stefano? And whatever the final outcome was, how would it affect the future of Southeastern Europe?
