I want to know the answer to the following question:
On what date did Napoleon's alliance overthrow the Directory?
All the background I'm provided with is that "He drew together an alliance with director Emmanuel Joseph Sieyès, his brother Lucien, speaker of the Council of Five Hundred Roger Ducos, director Joseph Fouché, and Talleyrand, and they overthrew the Directory by a coup d'état on 9 November 1799 ("the 18th Brumaire" according to the revolutionary calendar), closing down the council of five hundred.". Is that enough to answer the question?
Answer: yes
