I've just looked at Davout's order of the day for April 29th 1814
"The wish of Frenchmen, consecrated by the act of the Senate, the adhesion of the Legislative Corps, of the high dignitaries, of the principal courts of justice, of the communes and of the army, has abolished the imperial government in France and has called the Bourbon dynasty to the throne of France.
We therefore swear to our king,
Obedience and Fidelity
By order of the marshal Prince d'Eckmuhl."
