During the campaign of 1813, Eugène fought in the Battle of Lützen. Napoleon then sent him back to Italy, where he organised the defence against the Austrians, holding out on the Mincio until the abdication in 1814. After the fall of Napoleon in 1814, Eugène retired to Munich and at the behest of his father-in-law, King Maximilian I Joseph of Bavaria. He soon returned to Paris on the death of his mother, where he was welcomed by Louis XVIII and Alexander I of Russia, and immediately renounced his political activity and returned to his wife's family in Bavaria. Accordingly, he remained neutral during Napoleon's return to power in the Hundred Days.
