Answer:
He was succesful a first, but a failure in the end
Explanation:
During the first years of the Napoleonic Wars, Napoleon was succesful in bringing most of Europe under his control. He lead the French army to sounding victories against several enemies in Italy, in Germany, and in Eastern Europe, although he had many difficulties to conquer Spain.
Napoleon's tide changed when he decided to invade Russia. He had some victories at first, but an extremely cold winter, and the vastness of the country obliged him to retreat. During this retreat, he was often ambushed, and lost most of his army due to these ambushes, or due to the harsh winter.
His escape from Russia was precisely in 1812, and would mark his fate of several subsequent defeats that would utimately lead to his forced exile in the island of St. Helena.
The Civil War was based on a disagreement on slavery, but slavery was not the main issue.

President Lincoln's main goal was to preserve the Union and to get the Southern states to come back. Slavery was just something that had gotten taken care of during the Civil War.
