Wagram is such a huge battle that it can be hard to get your mind around all of it.
My fave anecdote is on the evening of the first day. The French are Attacking the Line of the Russbach stream. To stabilize the situation, archduke Karl shows up with a regiment of chevauxleger light cavalry and. Scatters the Saxon and French. His presence was a great morale boost, much like at Aspern-Esling when he grabbed the flag of the Zach grenadiers.
However, that's not what an army commander should be doing. That's a task for a cavalry brigadier.
And as an epileptic, it may have caused a lethargy the following day. Some accounts say that his two senior staff, Wimpfen and Grunne, actually ran the army.

"We've got the torpedo damage temporarily shored up, the fires out and soon will have the ship back on an even keel. But I would suggest, sir, that if you have to take any more torpedoes, you take 'em on the starboard side." Pops Healy, DCA USS Lexington.
