Yes, trained horses were very important in his battle tactics. He even won at Dreseden in 1813 thanks to Murat's large cavalry charge on left allies wing, while Imperial Guard pushed allies on their right wing.
He also tried delivered large cavalry charge at Leipsig, but alleis had more horses in their disposition.
In Russia 1812 French lost many, many horses and many experienced soldiers, officers and generals.
These were also big problems. Therefore Napoleon must used these young and inexperienced MarieLouises soldiers. They can not fought in 1813 as old veterans from Austerlitz 1805 or Jena 1806.
Napoleon played one card game in 1815. He tried attack in Belgium, however his army was not fully prepared yet.Originally Posted by JaM
Davout here could not help him too much, but he could help him in Paris. Napoleon needed Paris as his main base which can gave some reinforcements. Napoleon did not know, would British and Prussian fought in Belgium or would they withdrew or would they waited there for allies. Russian and Austrian armies were on the route.
Napoleon would like to quickly defeat British or Prussian, but he knew that even his victories there would not gave him a peace or brought the war to the end. Therefore he needed trusted man which can help him create new Grande Armee and reinforcements. Davout was good in this position.
