I'm not sure the order of the day led to his removal, that seems to have happened before Napoleon found out about the order.

Looking at the Correspondance, Bernadotte was still being sent orders on the 8th of July (Marbot's story of him being dismissed on the battlefield must be untrue) but on the 9th an order reorganising the army states 'the Saxon corps will form a detached corps under the command of general de division Reynier'.

Schonbrun 29.7.09 to Minister of War
"If you have occasion to see the prince de Ponte-Corvo, express my displeasure to him at the ridiculous order of the day which he has had printed in all the papers, all the more out of place because he had daily brought me complaints against the Saxons. This order of the day contains, besides, several falsehoods. It was general Oudinot who took Wagram at noon on the 6th; therefore the prince de Ponte-Corvo could not have taken it. It is no more true that the Saxons had pierced the centre of the enemy on the 5th, they didn't fire a shot. In general I am quite happy for you to know that the prince de Ponte-Corvo has done nothing in this campaign. He is a has-been, who wants money, pleasures and status but who does not want to purchase them by the dangers and fatigues of war. The truth is that that 'column of granite' was constantly in retreat."

It does sound as if he has only just found out about the order at that point, unless of course it was just learning it had got into the papers that made him blow his top.

The interestin sequel is that 7.8 he wrote to the minister with instructions for dealing with the English attack on Walcheren.
"if the English expedition is serious and the prince de Ponte-Corvo is at hand, put the 24th and 25th military divisions under his orders and send him to lead the movement, or send marshal Moncey."

So Bernadotte wasn't considered completely useless: Moncey was put under his command and he was later given command of the Dutch army until he was removed abruptly on Sept 11th partly for corresponding with intriguers in Paris and partly again for an order of the day which did not meet with Imperial approval.

Definitely an irretrievable breakdown of the relationship.
