FWIW, summary of Napoleon's critique while in exile 15 years later:
From exile on Elba fifteen years later, Napoleon analyzed the Battle of Stockach and the French defeat: its cause, he concluded, lay in Jourdan's division of force. Although Jourdan had increased concentration from his dispositions at Ostrach, the French force was still over-extended. Against a more concentrated force, the Austrians could not have moved troops from the left to reinforce the right flank when Saint Cyr and Vandamme attacked from front and rear. Furthermore, Napoleon averred, Ferino's force on the French right had not been concentrated sufficiently and d'Hautpoul's cavalry assault had taken too long to materialize, giving the Austrians the upper hand. The Austrian left had halted his assault, freeing men from the southern flank to reinforce the northern one. Importantly, the Austrian line was short enough that troops could move quickly from the southern flank to the northern one. Furthermore, Napoleon argued, Jourdan had retreated north-northwest, to the Black Forest to protect Alsace. He should have retreated south, to join with André Masséna's well-positioned Army of Helvetia, where in combination the Army of Helvetia and the Army of the Danube could have combined forces to defeat the Habsburg army. With Jourdan's misguided overall strategy, Napoleon asserted, the French snatched defeat from the jaws of victory.
