I want to know the answer to the following question:
Approximately how long did Napoleon take to prepare another Danube crossing after his defeat at Aspern-Essling?
All the background I'm provided with is that "After the setback at Aspern-Essling, Napoleon took more than six weeks in planning and preparing for contingencies before he made another attempt at crossing the Danube.". Is that enough to answer the question?
Answer: yes
