This is one of those questions that is near impossible to answer.
The best I can give you, based upon my reading, is that it is likely that slavery would have continued for quite a while longer. Over time, though, it would have held a diminished role in society as the South industrialized. The advent of the assembly line would have further pushed the decline.
Holding slaves was a morally bankrupt AND expensive endeavor. For a long time, the cost benefit analysis for slave owners was that they could get years of work out of a person without wages. Eventually, with technology, this would have made the institution less of a good "investment," combined with moral pressure as most of the Western world divested itself from slavery.
So, you'd likely see a more pronounced version of our de facto slavery with migrant farm workers in the United States.
The events that helped the Allies win the war in Europe were:
-the Nazi defeat at Stalingrad
The Battle of Stalingrad was a combat between the Red Army of the Soviet Union and the Wehrmacht of Nazi Germany and its allies for the control of the Soviet city of Stalingrad, current Volgograd, between August 23, 1942 and February 2, 1943. The battle took place in the course of the German invasion of the Soviet Union, in the framework of World War II. The serious defeat of Nazi Germany and its allies in this city meant a key point of severe inflection in the final results of the war and represents the beginning of the end of Nazism in Europe, as the Wehrmacht would never regain its previous strength nor would obtain more strategic victories in the Eastern Front.
-the North African campaign
The North African Campaign was the second most important front during the Second World War, after the Eastern Front. It took place in the desert of North Africa, from June 10, 1940 and until May 16, 1943.
Having the Axis forces fighting on a second front in North Africa, the Western Allies helped in some way the Soviet Union, which was fighting against the Axis on the Eastern Front.
Answer: They made an impact
